The managers of SMEs and VSEs too often perceive the issue of cybersecurity as a technical and IT subject. The human factor is at the heart of almost all cyberattacks.

Ransomware

Ransomware is software that takes your data hostage and paralyzes your system while waiting for a ransom, most often in cryptocurrency.
Often attackers threaten to disclose certain personal data publicly. Attackers seek to create a sense of urgency and panic by issuing an injunction and sometimes a ransom that increases over time.

Intrusion Into Your Information System (IS)

In this attack, the attackers manage to break into your IS to alter its operation or steal data to resell it. In the first case, we are faced with a desire for destabilization or sabotage. In the second, it is more akin to espionage or theft.
Most of the time, a human error is at the origin of this intrusion which occurs via an email containing an attachment, a visit to a corrupted site, or a connection from an unsecured public network.

Account Hacking

Account takeover is taking control of an account from its owner. From then on, the attackers can access all the functionalities and information this account is entitled to. It can be an email account or social networks but also access to an intranet or management tools.
Most often, the attackers only had to force a password that was too simple or send a phishing email asking you to enter your password. Sometimes, they may use spyware capable of recording letters typed on a keyboard.

Identity Theft

Historically, it was about taking a person’s identity to carry out fraudulent actions. Today, criminals prefer to impersonate companies to trick their customers, place large orders or take out loans.
To do this, they do not hesitate to recreate a complete digital identity with email addresses and mirror sites similar to their victims. Some falsify purchase orders and invoices and even go so far as to register with the commercial register.

Phishing

Phishing, or Phishing in English, is not an attack but rather a way to prepare for future attacks such as account hacking, intrusion, or even Ransomware.
This involves pretending in an email to be a reliable and trustworthy source to deceive the victims and thus obtain confidential information, such as access codes, or encourage them to act: click on a malicious site, open an attachment, install software, enter a form, etc.

Denial of Service Attack or DDOS Attack

A denial of service attack aims to make an online site or service unavailable by saturating bandwidth or mobilizing system resources. This artificial peak in stress considerably slows down the operation. It can go as far as causing a breakdown and, therefore, a system shutdown with the consequences that can be imagined in the case of a merchant site, for example.
It also happens that this type of attack serves as a diversion for intrusions or data theft.

Transfer Fraud

Wire transfer fraud is a variant of identity theft that often uses the technique of Phishing. It consists of contacting an accounting department employee and obtaining from him that he “voluntarily” makes a transfer.
To do this, the attackers can pretend to be a supplier awaiting payment whose bank details have changed. Some even go so far as to pretend to be employees who have changed banks and thus have their wages paid. It can sometimes take several months before the company realizes the deception.
A variant of this type of attack consists of contacting the accounting department, pretending to be the manager or one of his representatives, and asking to execute transfers to accounts abroad urgently. The scenarios have often been very carefully studied to make them believable and create a sense of urgency.

Disfigurement

Disfiguration is a deliberately very visible and sometimes publicized attack that aims to damage the image and credibility of a company by modifying the appearance and content of its website or its accounts on the networks. Most often, the motivations are political or ideological. However, it is not uncommon for this type of attack to be identified as former employees acting out of revenge or on behalf of competitors.

Two-Factor Authentication – Opportunity Or Risk? https://www.techreviewscorner.com/two-factor-authentication-opportunity-or-risk/ https://www.techreviewscorner.com/two-factor-authentication-opportunity-or-risk/#respond Tue, 12 Jul 2022 09:44:43 +0000 https://www.techreviewscorner.com/?p=4193 Double is not automatically better: conscientious handling your data is the be-all and end-all.

Double is not automatically better: conscientious handling your data is the be-all and end-all.

Two-factor authentication ( 2FA ) is a “strong customer authentication” measure that checks whether an electronic payment transaction is legitimately made. The 2FA consists of a first factor for the identity of a user, which consists of a username and password, and a second, independent factor. The latter must either be something that only the rightful owner of an account can know, possess or be.

This ensures that potential hackers find it difficult or impossible to access third-party data. The 2FA promises users greater security against unauthorized access and data misuse. But does 2FA only offer advantages, or does it also entail risks?

The Two-Factor process is a clear opportunity.

Modern solutions generate one-time passcodes via tokens and apps or also use the biometric functions of smartphones and tablets. These processes usually run isolated on a second device. This makes it difficult, if not impossible, for a hacker to complete signing into an account that is not theirs or authenticate for a purchase they are not authorized to make without access to that device. With 2FA, an additional difficulty for attackers is that passcodes are tied to the original session. This means that even if login data is read, hacked passwords cannot be used again in a new session. Therefore, the benefit of multiple authentications against hacker attacks is undisputed and an opportunity in the digital age. However, the implementation and use of authentication measures play a crucial role in ensuring that users are protected.

And As A Possible Risk.

The “Default” Password

Risks often arise from users not handling their data responsibly enough. It is enough to choose an insecure or uniform password for several accounts. Especially when a user selects a password for more than one service and changes it only rarely or not at all, he is exposed to the risk that an attacker who hacks any of these services will gain access to many of the user’s access points with the same password.

Security Versus Usability

Another aspect that should be considered when discussing the risks of IT security solutions is user-friendliness. In terms of mobility and flexibility, token solutions stand out positively from alternatives. However, they have deficiencies in handling, safety, and cost. A token must be assigned to a user; if the latter loses the device, time-consuming workarounds for temporary access would be necessary. Also, tickets are expensive due to their short lifespan of three to four years. In addition, a token’s flexibility is limited because the user must carry it with him at all times. In this case, usability suffers from security.

To increase user comfort again, “adaptive” two-factor processes are used. To do this, providers use IP or MAC addresses or locations that users automatically transmit for authentication. As a result, they share access to accounts and payment options without the user having to interact. For him, the registration or authentication is reduced to entering his name and password – which is not in the sense of a 2FA. Thus, the aspect of usability beats that of security.

Biometric Distortion

Other risks can arise in the area of ​​biometric systems. Physical characteristics are individual, but they do not automatically protect against misuse. If a system is not geared towards recognizing that someone is alive, a photo of a face or eye can be used to trick it.

A test by the Chaos Computer Club (CCC) showed that placing a contact lens over a photo of an eye was enough to replicate the shape of a natural eye. This is how you fooled the iris scan of a smartphone. Even fingerprint scans are not entirely secure; fingerprints are left everywhere, especially on your smartphone. As a result, this practice already brings the key to the lock with it.

However, it must be mentioned that technical processes are constantly being further developed, and there are now biometric systems that reliably recognize whether a photo is just being held in front of the camera or whether the natural person is standing in front of it in three dimensions.

The Best-Case Scenario

Two-factor authentication offers an undisputed benefit: it verifies whether e-commerce transactions are legitimate. Through the generation of one-time passwords, TANs, or unique biometric features, it is individual and thus effectively protects against hacker attacks in several steps. However, 2FA is only as secure as the developer makes it or the user adheres to it. A genuinely secure 2FA must not switch down by a factor on its own to increase usability, as in the case of adaptive two-factor methods.

In addition, 2FA is not a guarantee of security. If you enter your data on a fraudulent website, even a particularly secure procedure can no longer protect against unauthorized access. Every user must handle their data responsibly.

Do you want to be sure that your data, emails, photos and other personal information you keep on the web are protected from malicious people? The first thing to do is watch your accounts well on various websites and providers.

In today’s article, I want to show you how to create a 100% secure password, or almost, to use when you register for an online site or service. It may seem like a trivial thing, but I assure you that it is not like that! There are many precautions to take when you invent one, and not all of them are so obvious.

You need to have strong passwords because, by now, there are tons of bots (automated programs) that try to steal user accounts by guessing your login credentials. Once logged in, not only do they have access to all your info, but they could also change your credentials and steal your account.

Cyber ​​security is paramount nowadays, and you need to know the precautions to take on the internet. For this reason, I decided to write a tutorial on how to make your password and choose combinations that hackers and bots will have a hard time finding.

How To Generate a Secure Password

Suppose you understand well the risks involved when someone manages to hack into your email account and you have information or photos that you would not want anyone to be able to steal from you. In that case, you will also know how important it is to protect your profile.

The first step is to have rugged credentials to guess or guess, and now I’ll show you how.

Follow the six rules to create a secure password:

  • use eight or more characters
  • enter combinations of uppercase and lowercase letters
  • use at least one number
  • write at least one special symbol between #! – @ *
  • do not use names, words with complete meaning or dates
  • use a different password for each account

Today we are registered on hundreds of sites and online services, and having different login credentials everywhere makes it almost impossible to remember them by heart, even if one creates a pattern to follow. For this, I advise you: in addition to producing them following the instructions above, also use software for their management, which remembers them for you. Soon I will also deepen this point.

Test The Difficulty

You have followed all the rules and advice given so far, and now you are wondering: How secure is my password? When you enter it, on many sites, next to the field where you entered it, an indicator does a quick check and shows you its security level. It usually ranges from weak to vigorous or red to green, but this is not always a reliable measure.

Keep Your Passwords In A Safe Place.

Even if you have taken all the necessary precautions and created a password impossible to guess, if you then write it on a sheet of paper, under your email with which you log in, and leave it stuck on your pc or your desk in the office, you have just wasted so much time for nothing.

On the other hand, remembering such a complicated one by heart is truly a feat. Let alone if you have dozens or hundreds of them. Here comes the problem of managing your passwords: either you have the best memory in the world, or you can’t. You can also create patterns or associate them with something you remember, but as long as you haven’t used it for a while, you still risk forgetting it.

Thankfully you don’t need to do this because you can use a password manager to do it for you. This software remembers all your credentials and keeps them in a safe place. They have several advantages, but there are two that I recommend you use them for.

The first is that you have to remember only one password to access the program, and once you have entered your account, you can recover all the others.

The second is that these online services allow you to carry your passes on any device, as long as you log into your profile. In addition, they are so advanced that they integrate perfectly with the browser. You often don’t even have to go looking for them because they automatically suggest your login credentials when you are on the service’s login page.

One of the best password managers on the market is 1Password which is paid, but if you have a Mac, you have free Keychain Access, or by creating a Google account, you can also use Google Password Manager. However, in the latter case, you must always use Chrome and log into your profile.

Strong Password Generators

If you don’t feel like remembering the rules above and struggling to create a password every time, the simple solution is: to use a password generator.

What is it about? As the name suggests, this is a small program that generates a secure password for you. To create it, this software uses random combinations of symbols, following the rules seen above and always manages to reach a strong password, that is, of high difficulty to guess.

Convenient, isn’t it? You’ll also be pleased to know that you probably don’t even have to look for such a program because your operating system or browser already has this built-in!

If you use Google Chrome or a Mac, for example, every time you need to register somewhere, you will see that your computer will suggest a secure password to use for registration.

The same goes for smartphones: whether you have an Android phone or an iPhone, every time you want to register on some site and find yourself on the registration page, your phone will suggest a secure password.

And you don’t even need to copy it! Your pc or smartphone will remember it for you and associate it directly with your account.

Either way, you don’t have to use it, and you can make your own, but I recommend that you listen to their suggestion. You can also resort to password generators like LastPass or Avast, which, in addition to protecting your PC from viruses, also have solutions for web security, such as a private VPN connection and the ability to create secure passwords.

In Short

A secure password must protect anything that someone can access without authorization. Here I am not only talking about your online services but even that of your computer or even that of your WiFi. Indeed, when someone logs into your network, they may also access much of the data on all connected devices. In this regard, you can read the article on how to change the modem password.

In short, if you want to sleep peacefully, I advise you to follow the advice seen today and, if you have any additional questions, do not hesitate to ask.

IT security is often underestimated in companies, although it can often be significantly and cheaply improved significantly. Arguments like “know who I’d be interested in” or “I don’t have time for” are just excuses. The risk of attacks and troubleshooting costs are higher than you think.

After a pair of articles on mobile security – Protecting corporate data on mobile devices and How to protect data on a lost or stolen mobile device, we bring you a summary of security tips. See how easily you can protect your business in the virtual world.

Back Up Everything Regularly

We all know how important backup is. But how many people are backing up? Hand on heart. Where do you have an accounting deposit? Customer database? Company photos or videos, or other important documents?

You can use Dropbox, Google Disk or OneDrive for backup. Thanks to your cloud, if you do not trust foreign cloud solutions, you can use domestic providers or have data only with you. In the worst case, make regular backups to an external drive manually. It’s not convenient, and you can’t do it too often, but at least some backup is better than none.

Encrypt The Corporate WIFI And Separate The Internal Network From The One Used By The Visitors

Always password protects your corporate WIFI. Use a strong encryption algorithm (WPA2-PSK (AES)) and a strong password. If the router has default WIFI, check its settings and change the password. Change your password regularly, at least once every six months.

INFO: Many WIFI routers allow you to set up the so-called Guest zone – customer zone. This is a separate WIFI network that visitors to your company can use. From this WIFI, guests cannot connect to your printer or computer, and at the same time, you significantly reduce the risk of stealing company data.

Do Not Use Public WIFI

The security risk of unencrypted and public wireless networks is high. Anyone with password knowledge can connect to the network and try various attacks. Never send personal information, login details or bank card details via such WIFI networks.

TIP: If you already need to use the public network – in a cafe, airport or hotel, connect using a VPN – a virtual private network. This is a solution where your device will appear as part of another network. The main advantages are anonymity and security, and your communication will be encrypted and secure. For example, the creator of the Opera browser offers a simple and free solution. Download the Opera VPN app for Android or iOS. All you have to do is install the application, turn on VPN in your browser, and you can safely browse the Internet with Opera.

Protect Your Emails

There are two ways to read and write emails through a web interface – typically Gmail or a Microsoft Outlook email client. With the web interface, you don’t have the option to set up a connection, and you’re almost certainly logging in with an encrypted connection. You have already set connection parameters for the email client, and you can connect to the email server both encrypted and unencrypted. Your emails can be read with an unencrypted connection. Therefore, check how you are connected.

TIP: Verify the connection settings in Microsoft Outlook using the settings File – Account settings (select Account settings) – select the email account you want to verify – Change – Additional settings, Advanced tab. If you see the SSL connection type, you are connecting encrypted.

Use Strong And Unique Passwords

This rule has been with us since the beginning of computer systems. Basic principles for creating a strong password:

  • Do not use well-known words – admin, password, admin.
  • Use uppercase and lowercase letters, numbers, and special characters such as.,?! * /.
  • The minimum password length should be eight characters.
  • Change your passwords regularly.
  • Each password should be unique.

Password Access The Device

There is one main rule in the world of security. The system is only as secure as its weakest point. Therefore, you need to set a password on your devices. Of course, please do not write this password on the piece of paper next to the computer and change it regularly.

Use a Security Certificate (Green Lock) On The Company Website.

Certificates are currently free and dramatically increase security. All data that is sent or received will be encrypted using this certificate. Because Google takes security very seriously, it rewards sites that use the encrypted HTTPS protocol in the URL with better search rankings. In early 2017, Chrome will mark non-HTTPS sites as unsafe

Do Not Use Foreign USB

Abroad, it is popular to leave thrown USB keys near companies. These USBs contain viruses and infect the entire corporate network when inserted into a computer. It is important that you use an updated antivirus program and not unnecessarily insert third-party devices into computers.

Do Not Open Suspicious Emails

A very simple way to infect your device is to send an email with a virus in an attachment. Therefore, do not open attachments from unknown senders and use an updated antivirus program.

It is easier than ever for criminals to break into IT systems, paralyze websites, or essential access data in today’s networked world. What attacks are companies exposed to, and how can they protect themselves from them?

“Ask your doctor or pharmacist about risks and side effects,” or your IT security expert, if you have one. And you should! Because as beautiful as the world of digitization with all its possibilities may be – from smartphones to cloud computing to the Internet of Things – its “side effects” are just as threatening.

Inadequately protected IT systems take their toll and sometimes have existential consequences. The range of possible damage is extensive: repair or replacement costs for individual components, downtime, downtimes, or loss of image. In extreme cases, the company is threatened with bankruptcy.

Threat Situation

For a good eight out of ten industrial companies, the number of cyber-attacks has increased in the past two years, reports Bitkom. But large corporations are targeted by Internet gangsters: what is vulnerable is attacked! More than 70 percent of companies have been victims of cyberattacks in the past two years. The shotgun is used for shooting, and the ammunition is malware that lodges itself in IT systems as a so-called malware infection.

Advanced Persistent Threats

APTs are targeted attacks intended to give the attacker permanent access to a system. This type of attack is usually about data theft. The focus is on selected institutions and companies, mainly from the industrial and financial sectors. The latest methods and developments are used, as the attackers want to remain undetected and use sophisticated evasion techniques. To gain access to a network, the attackers use what is known as spear phishing. This is a kind of social engineering in which specially prepared emails are used to write to company employees and induce them to take any action to gain access to the system.

Attacks on Industrial Control Systems

Many production systems are still running with outdated software for which there are no longer any updates. This opens the door to attackers. The malware mostly gets into the system via phishing emails and exploits known vulnerabilities. In the developments around Industry 4.0, there is a substantial potential risk multiplied by increasing networking.

(D) Dos Attacks

Distributed Denial of Service attacks (D) DoS attacks) are targeted attacks on company servers. The aim of these attacks is not to steal or manipulate data. Instead, the company’s servers and associated services are bombarded with inquiries for so long and intensely until there are sensitive disruptions or they collapse entirely. If the attack is aimed at the webserver, the company’s website can be completely paralyzed in extreme cases. If the spell affects the mail server, incoming and outgoing mail is idle.

On the one hand, these attacks prevent further work with the services. On the other hand, it is damaging to the company’s image if its website or online shop can no longer be reached. (D) DoS attacks can now be conveniently purchased from hacker networks, which increases their occurrence. Hundreds of thousands of “zombie” computers (externally controlled PCs contaminated with Trojans) send data packets to the target server via botnets. As a preventive measure, an emergency plan can be agreed upon with the provider. He can use technical means to detect such an attack and initiate appropriate emergency measures.

Ransomware

Also known colloquially as encryption Trojans, these attacks attempt to block access to your data by encrypting data storage devices and hard drives. After paying a ransom, the Trojan promises to reverse the encryption.

Protective Measures

Virus scanners and firewalls are not enough to cope with this threat, increasing both quantitatively and qualitatively. Often the most significant security risk is in front of the computer. Typical reasons for human error are insufficient qualification, operating mistakes, carelessness or stressful situations. Employees must be made aware of the issue through training. Otherwise, the most expensive investments in defense against external threats will be ineffective. In addition, a code of conduct, which regulates the handling of data in a binding manner for everyone, helps.

Malicious threats are not the only source of threats to IT systems. The “unintentional” threats in the digital age include technical failures such as crashing computers, network overloads, or defective data carriers. Periodic backups, incorrect or missing password management, or inadequate emergency management can be traced to organizational deficiencies. And finally, acts of God such as fire, water, dust, or lightning strikes can also cause considerable damage.

To protect yourself against such threats, your threat situation must be analyzed, and the individual security level determined. Only then can a comprehensive security concept consisting of technical and organizational measures be designed. Because one thing is clear: there is no one hundred percent IT security, and most companies would not be affordable.

The time factor, tight budgets, and the increasing complexity of the subject make it difficult to deal with the topic until it crashes. Only when the child has fallen into the well and the damage has occurred action taken. Don’t let it get that far! Preventive measures are the more effective and cheaper way to protect yourself from cybercriminals.

With the “Zero Trust” model, it is possible to increase security significantly: The security concept is based on the principle of not trusting devices, users, or services inside or outside your network. In today’s post, we look at how the Zero Trust model works and contrast the advantages with the disadvantages.

Zero Trust: Don’t Trust Anyone!

Zero Trust is not a product but rather a technology philosophy, a framework idea that companies can implement. Zero Trust’s philosophy: “Don’t trust anyone blindly” – only verification can create Trust.

Specifically: Where Does Zero Trust Apply?

In this world full of cyber security threats, companies have a lot to cope with: Mobile workplaces such as the home office want to be just as secure as the company’s workplaces, and in both cases, countless devices and applications are used. The zero trust model starts with the fact that requests are not automatically classified as trustworthy even if they come from the company network.

In principle, all elements – all devices, services, users, etc. – are treated precisely the same way as if they came from open and insecure networks: they are initially not trusted. Following the zero trust principle, neither authenticated users nor end devices nor VPN connections are charged – even if they are generally classified as secure because automatic Trust would immensely increase the risk of data leaks – possibly triggered by internal company employees who move through the network without checking and with absolutely no restrictions.

Specifically, the Zero Trust approach means:

  • Network users are authenticated, authorized, and validated in real-time and, if necessary, repeatedly. This serves to ensure the required authorizations. It is not enough to check the identity of the user once.
  • The principle of least privilege applies to the zero trust model: identities are initially given the lowest access level. If further cybersecurity measures are added, movements in the network can be considerably limited using least privilege access.
  • When implementing these zero trust principles, companies must first define assets worth protecting: data and systems, for example, classified as critical. These assets are covered with a comprehensive platform – contrary to the otherwise prevalent assortment of individual solutions built around individual users.

To successfully implement the Zero Trust model, the interaction of various security applications is necessary: ​​In addition to the three points just mentioned, multi-factor authentication, network, and device monitoring, and behavior analysis and automation must also be considered. Nevertheless, the user experience also has to be suitable to not seduce users into compromising security. This tightrope walk can be achieved using IAM (Identity and Access Management) solutions.

Correctly implemented zero trust models are tailored to all behavior patterns and data points representing everyday life in the company network. Zero trust solutions grant or deny access rights based on various parameters, such as time, location, operating system, device type, or firmware version. Special zero trust tools allow advanced protective measures.

To maintain Trust in the zero trust model, a risk analysis is always necessary – before access to IT resources is granted, they must be fully authenticated and authorized, and security checks on devices and applications are also carried out. The risk analysis must include locations, the context of processing, and users. If anomalies are detected during monitoring, these are generally classified as risks and answered with previously defined security measures.

Advantages And disadvantages of Zero Trust

The main advantage of the Zero Trust principle is obvious: By reducing the risk of attacks, cybersecurity improves immensely. This enhances data protection and data security at the same time.

However, practice, which we briefly introduced above with a few points for consideration, shows that Zero Trust is, unfortunately, more of a security philosophy than a new standard in cybersecurity. Any risks and functionalities are difficult to assess in advance, posing unexpected challenges for the company. This may increase the costs for IT security, and the fact that the systems must be constantly monitored and maintained will not result in any reduction of the expenses or effort.

The zero-trust approach is always interesting: Everything in and outside of the company’s network must be verified before Trust; if necessary, also repeated. This curbs unnecessary network movements and thus can immensely improve security. However, the effort required to implement the zero trust principle successfully is not (yet) feasible for the majority of all companies, so it currently makes sense to deal with the protection of identities. If there will be zero trust solutions in the future that can offer user-friendliness in addition to protecting company assets, it is worth taking a closer look.

We can shop, bank transactions, or deal with authorities on the World Wide Web, sometimes more, sometimes less conveniently. There are only two main risks: Firstly, you act anonymously on the web. On the other hand, the data traffic can eavesdrop. These two risks are reduced with the help of the SSL certificate: the business partner is identified, and the data (bytes) sent are encrypted. SSL abbreviates “Secure Sockets Layer” and can be translated as “secure connection layer”. SSL certificates are issued for one year and primarily encrypt the data stream on websites but are also used in e-mail traffic.

Functionality And Application of SSL Certificates

It seems that the user often thinks that he has nothing to hide. But let’s switch to real life: Would you like to have a look in the cabin while trying on your clothes? Or when withdrawing cash over your shoulder? It’s about confidentiality, which is a matter of course in “normal” life. Organized fraudsters regularly trick unsuspecting bank customers into providing their online banking data on fake websites, including TANs and PINs. Wireless LAN, i.e. wireless networks, reveal what broadcast is – unencrypted radio signals are broadcast about as openly as radio broadcasts on the radio. This invites criminals to rob their identities.

With the “HyperText Transfer Protocol Secure” (HTTPS), the first step towards data security was taken in 1994. The data to be transmitted is encrypted thanks to HTTPS at 128 or 256-bit level, without additional software on the computer. HTTPS also checks whether the partner’s identity is correct. Phishing attacks by forwarding them to manipulated websites are made much more difficult by this type of authentication. Financial institutions, in particular, work via HTTPS servers. Many shops, however, ultimately leave it up to the user whether he uses the encrypted HTTPS or the unencrypted HTTP.

SSL is used when connecting via an HTTPS server. It is a pure recording protocol that regulates the encryption between two computers and at the same time checks whether the data entered on the user side is output exactly as it is on the provider side. If the technical details are simplified, SSL works like this: A second connection (“SSL Record Protocol”) is pushed over the existing line. Check digits are calculated and added at regular intervals from the data sent. This value is compared again at both ends of a connection.

However, the “SSL Handshake Protocol” ensures that the participants’ identification data is transmitted before the data is exchanged. It also negotiates the fragmentation and encryption methods that are to be used for the connection. Now coded bits of information flow through the ether of symmetrical algorithms: the receiving computer decodes, combines and makes the information readable for the user. Or, to put it more simply: The two computers involved agree on a code and a uniform size for the data packets to be transmitted.

The SSL certificate appears during the “handshake”: A certificate authority (CA) issued the digital identity card and assigned it to a person or organization using a publicly available signature verification key. The certification authority notifies this assignment by approving the certificate with its digital signature. If a certain code is used, the composition of the code can be used to deduce and confirm who is using this code.

Why Do Employees End Up Falling Prey To Cybercriminals? https://www.techreviewscorner.com/why-do-employees-end-up-falling-prey-to-cybercriminals/ https://www.techreviewscorner.com/why-do-employees-end-up-falling-prey-to-cybercriminals/#respond Tue, 16 Nov 2021 09:15:51 +0000 https://www.techreviewscorner.com/?p=2939 Online crime has exploded in the last decade.

Online crime has exploded in the last decade. Since 2011, online fraud has risen by 81.3% worldwide, something that affects ordinary users and companies. Corporate cybersecurity should be a priority, and businesses should strive to understand what leads to their employees becoming victims of cybercrime.

In general, the response data obtained by cybercriminals among workers is high: 47% of employees in the IT industry acknowledge having clicked on a phishing email, and 43% of people say they have made a mistake in their work with repercussions on cybersecurity.

This occurs because the activity of cybercriminals has been increasing. The costs that cybercriminals have to bear are not that high, but their return is. Legally pursuing them is, on the contrary, very complicated, which makes their activity a kind of no-man’s-land.

On the other hand, and despite the increased awareness of the effects of cybercrime, Internet users continue to be potential and recurring victims of these practices, both in their private lives and at work, opening the door to potential millionaire losses in the latter case.

Why Do We Keep Falling Into The Trap?

But why do workers keep falling for cybercriminal scams? Sometimes knowledge fails, and the absence of internal training in cybercrime leads to “stung.” Therefore, companies must constantly train their staff in terms of security.

In other cases, cybercriminals have played well with human nature. Thus, for example, your emails and hooks are capable of mimicking legitimate messages. Their actions seem feasible, leading to less mistrust. In one of the latest waves of bank scams in northern Spain, cybercriminals even switched languages to make the idea that they were staff from the affected bank more credible.

In addition, cybercriminals play with human psychology, using risk aversion, fear of problems, or panic in the face of economic loss as elements to capture the attention of their recipients. Just as these hooks work in legitimate environments, such as marketing, they also work in those not, such as cybercrime.

To all this, the context must be added, which has not been the most positive in the last two years. In addition to imposing teleworking and thus opening potential security gaps, the coronavirus crisis created a situation of high anxiety. The stress leads to more errors committed and makes it easier to fall into the clutches of cybercriminals.

Finally, it must be added that there is a starting bias that makes us weaker: a study has shown that it is assumed that one “is not going to fall” and that it is always the others who bite.

How To Shield Yourself

In conclusion, falling into the traps of cybercriminals is too easy, forcing companies to take control of the situation and prevent it before they cure. Investing in cybersecurity saves money from the potential impact of security breaches, but it also positions the company much stronger.

Why A Zero Trust Security Platform Is The Best Way To Protect Your Data https://www.techreviewscorner.com/why-a-zero-trust-security-platform-is-the-best-way-to-protect-your-data/ https://www.techreviewscorner.com/why-a-zero-trust-security-platform-is-the-best-way-to-protect-your-data/#respond Wed, 03 Nov 2021 16:49:30 +0000 https://www.techreviewscorner.com/?p=2879 In recent years, there has been a move to allow employees to use unmanaged devices to connect to business applications over the Internet.

In recent years, there has been a move to allow employees to use unmanaged devices to connect to business applications over the Internet. The COVID-19 pandemic accelerated moves in this direction.

When people connect any device they want to an organization’s network, Zero Trust architecture becomes a must. Unfortunately, there has been substantial confusion about what Zero Trust means.

What Is Zero Trust Security?

Zero Trust security eliminates the idea of trust from an organization’s network architecture. It prevents successful data breaches because all devices, identities, and users must prove who they are before they are given access to data. When answering the question, what is zero trust security, it is good to think about the motto, “Never trust, always verify.”

Zscaler describes Zero Trust as the framework that allows specific capabilities to secure an organization in the modern, cloud-based world. At the heart of Zero Trust is the concept of least privileged access. This assumes that no user’s application should ever be inherently trusted.

The Zero Trust concept begins with the idea that everything is hostile and should be treated as such. Only when a user, application, or system establishes trust will access be granted. Trust is determined using the user’s identity and contextual information.

For example, a user may verify their identity. However, a Zero Trust system will also evaluate the user’s location based on their IP address. Suppose a user typically attempts to access a system from Minneapolis, Minnesota, and now they are trying to access it from Tegucigalpa, Honduras. In that case, their access request is out of the context of what is considered the norm and should raise red flags.

Another example of context is a user who verifies they are attempting to access information from a known IP address but is trying to access information at a time outside of the norm. For example, trying to access information during non-working hours would raise red flags. These policies serve as gatekeepers and protect an organization’s network every step of the way.

Why Is a Zero Trust Security Platform the Best Way to Protect Your Data?

The idea of assuming that everything is hostile seems like the intuitive thing to do. However, since the 1990s, corporations have approached security and identity management from the standpoint of creating a perimeter that uses endpoint-based controls. If IP addresses, protocols, and ports were approved, they were trusted to communicate inside the network.

This is dangerous, especially if workers are bringing in their own devices. Zero Trust approaches all traffic, be it inside the perimeter or outside the perimeter, as hostile. If workloads do not have the correct fingerprint or identity, they are hostile, blocked from communicating, and treated like a danger.

The environment agnostic approach to security allows applications and services to be secure even if communication occurs across network environments. There is no need for architectural changes or policy updates.

Keep Your Organization Safe

The most significant benefit of Zero Trust is that it keeps your organization safe. It securely connects users and devices to applications, allowing businesses to enact policies that work over all networks.

It is a fact nowadays that almost all areas of life are occupied by machine learning. The most advanced of them use artificial intelligence more or less but develop their products thanks to these technologies. Ubiquitously computing changed the world and pushed it to the way of supersonic progress. There is no place in the future for those companies who use calculators and fax machines instead of computers. Another question is the high-level programming that is responsible for AI stealing the workplaces of low-skilled employees. It is hard to say if this situation leads to encouraging studying or disappointment and demotivation of such staff. Anyway, it is a true story that technology brings much more benefits than harm to society. Let’s find out the most popular areas and discover what machine learning and AI brought to them.

Advantages Provided by AI and Machine Learning

You can add to this list more and more areas that change thanks to AI and made a huge spurt because of its influence. We believe that it is only for the best in general. For the modern person, it is hard to imagine his life without a smartphone or internet connection. They appeared before AI and machine learning, but all the devices became quality assistants and indispensable parts of our lives thanks to them.

  • Education. A lot of innovations start from the higher education system. Students are the most open and ready people for all kinds of challenges. So they took all the aspects of machine learning and AI into their daily life. A lot of online education programs are built with the help of AI that analyzes the involvement of the group and creates a special approach to the students.    
  • Space exploring. The magic place that every dreamer wants to enter is space. Technologies that are used in this area are the most innovative and modern. The common person is hardly understandable, but an obvious fact is that space tourism is closer than we thought. Thanks to AI, we can predict and calculate the behavior of the spaceships and avoid a lot of visible and hidden problems. Making decisions for the better functioning of all spaceship systems is a strong point and the obvious ability of AI that is necessary for the whole space industry.     
  • Medicine. It might seem that medicine is about humans and the qualification of doctors. It is indeed impossible to help a patient without the caring hands of nurses and doctors. Nevertheless, they can’t be successful without using medicines that were created thanks to the technologies in general and AI in particular. The biggest part of medicine development is analyzing the combination of components. Let’s not forget about high-tech devices that help surgeons with the most painstaking operations on the brain or heart. 
  • Connections and communications. Have you heard about clever automatic systems that distribute data streams and regulate network load? There are billions of users on the open internet who send, buy, order, book, make payments, watch movies, and do other things at the same time. This is possible thanks to machine learning and AI that are responsible for the whole system. It’s security and working capacity. 
  • Construction. You can say that we built pyramids without AI, and they are still standing. There are only two aspects we want to mention. The first one is the number of injuries of workers. Another one is creating infrastructure around. Predicting the number of citizens, their needs in roads, banks, shops, and restaurants distinguish good constructions from bad. To do it perfectly, you need to find out a lot of information about customers and make a deep analysis. Only based on the data that you receive can you start smart construction. As you see, AI helps to avoid mistakes again and builds more quality systems.
  • Creating machines and mechanisms. It seems that Boston Dynamics is a synonym of AI. Their creatures study and create their logic according to personal experience. Today they jump and dance. Tomorrow they will do a much harder job. They are frightening, a little but magical. This show is only one side of the coin. Only imagine how deep they can use machine learning for the huge mechanisms for all kinds of production. Looking forward, the future when robots will take part in society doesn’t seem so impossible.  
  • Finance and banking. Two centuries ago, gold and paper banknotes were money. Nowadays, you can use a lot of instruments to pay, sometimes even hardly understandable like cryptocurrency. Machine learning is important for this area in questions of security and protection of personal data. Online bots and clever, sensitive interfaces use AI and use it successfully. Systems of money exchange, trading business, IPO, and international financial system, in general, can’t exist without technologies anymore. 

How to Stay on the Top of the Tech Wave

When it comes to standard trends, you don’t need some specific education to keep abreast. You need to read about innovations and feel like you know enough. This level will actually be enough for conversational and general knowledge purposes. However, if you want to work in the field where Machine learning and Ai are implemented, you need to do much more than that. There are long, short, official, and commercial edu programs you can choose from. The only problem you can actually face is the complexity of these studies. Don’t give up! If you feel like you get stuck with doing your assignments, address a STEM-oriented student homework assistance service, such as MyAssignmentLab.com, and share your tasks with them. You will receive instant help with your homework and also understand how to work on similar assignments better and faster. Here, you have direct access to an assigned writer and can ask questions to get to the bottom of the problem. If you have decided to make Machine Learning and AI your profession, use all the means available, as these fields are the future.
