Lately, a new rise in the number of fraudulent software (also known as “malware“) allowing theft of passwords has prompted cybersecurity analysts to sound the alarm, warning users against identity theft, especially for companies that lack the necessary protections. Malware does not operate the same way as raw threats: users infected with these password-stealing malware will have their new codes hacked, even after changing them. Administrators can take several steps to stop this, but users should also be aware that cybercriminals can infiltrate their computers and steal their passwords discreetly.

Password-Stealing Malware Is Hard To Eradicate

During a brute force attack, automatic identification attempts on an application end up finding a vulnerable account. By using dictionary lists, cybercriminals can effortlessly perform thousands of login attempts on accounts that the system neither detects nor prevents. On the other hand, malware operates directly on the user’s computer and can roam the network for months undetected.

Malicious software operating on a computer can steal any data entered by the user, whether on a web page, on a company server or even an email. As soon as the user enters the information on the computer, the malware detects it and sends it to the network controlled by the cyber-hacker. Typically, the malware collects account IDs and associated passwords, but keyloggers (or “keyboard spies”) record every keystroke and trace it back to the cybercriminal, along with the type of app the user is using. Used the password.

Password theft is not the only danger caused by malware: it can also automatically download ransomware, rootkits, viruses and other malicious items to the infected computer. Sophisticated malware is difficult to detect, and it can take administrators months to identify.

Identity Theft Makes Businesses Vulnerable To Data Leaks

Cybercriminals can collect thousands of user IDs and their passwords through malware, gaining access to the corporate network. With a list of credentials, they can launch an automatic login attack on your network. Bulk retries allow them to check which accounts are active; they have to compromise them to reach your company’s network and exfiltrate all the data they want directly from the system.

Without the protection of a robust cyber security system, a hacker can infiltrate any networked system. Most companies have a remote connection outside their walls, leaving an opening for cybercriminals.

Any cloud-based system is susceptible to cybercriminal attacks, including password and identity theft. A business should always have cyber security protection that can detect and stop multiple login attempts. There are also several methods to protect against password theft and phishing.

Protect Computer Systems Against Malware.

Most password-stealing malware consists of several components: an installation process and a method to steal data from the user’s computer. Once it has collected enough data, the malware sends it to a server controlled by the cyber-hacker, which is accessible to anyone who connects to it.

Antiviruses are essential in cybersecurity for both personal and business computers. They are part of the elements required for compliance; each company should have an operational antivirus, updated each time the developer produces an improvement so that each new malware is immediately detected before it infects the computer.

Mail filters are also necessary to prevent malware from installing on a computer via email. Phishing is the first of the strategies used by cybercriminals to convince the user to install malware on their computer. The best email filters detect corrupt attachments and links to fraudulent websites; they then quarantine them to be examined later. This technology stops most email hacking attempts.

Two-factor authentication does not prevent malware from infecting a computer, but it prevents the cybercriminal from stealing credentials after compromising the system and stealing data. Administrators can then set up a login system allowing the detection of multiple login attempts and repeated failures to know whether or not a user has been the victim of identity theft.

Staying Alert: The Best Defense Against Malware

Whether password-stealing malware or data-stealing malicious software, the best defence is vigilance followed by action: equip yourself with an email cyber-security system that prevents malware from reaching your inboxes, including antivirus and other reasons. Once the malware has taken root in a system, it can be challenging to get rid of. Staying alert will help prevent most of this malware from compromising your business and productivity.

Information in its broadest meaning is today one of the essential elements for the development and growth of any organization’s business. The current social and commercial interconnection makes information security an essential element, as information is increasingly exposed to a growing number and variety of threats and vulnerabilities. Consequently, adequate and effective protection is needed. But it happens that sometimes the confusion between the terms “information security, “computer logic security,” or “logical security” causes the specific nuances of each of them to be lost.

Differences Between Computer Security And Information Security

Insecurity, it is essential to know what we are referring to at all times precisely and unequivocally. It is, therefore, necessary to start by pointing out the distinction that exists between the previous terms. Thus, “computer security” would protect the technological infrastructures on which the company or organization works. The “information security” for its part has as its objective the protection of systems and information, as long as they are always accessible, that they do not suffer alterations and that their access is allowed exclusively to duly authorized persons. Information security, therefore, refers to the confidentiality, integrity, and availability of information and data. Finally, “logical security” involves all those measures established by administrators and users of information technology resources, which are intended to minimize security risks in their daily operations, in which information technologies are used.

Threats To Information And Computer Security Principles

The main threats of human origin that affect hardware, software, and data in computer security are usually theft, fraud, sabotage, espionage, hacker action, and malicious code. These threats typically materialize through phenomena such as:

  • Interruption: destroying hardware, deleting programs, data, operating system crashes, etc.
  • Interception: such as illegal copying of programs or eavesdropping on data.
  • Modification: by modifying databases or modifying hardware elements.
  • Generation: when adding network transactions or adding database records.

To start fighting against the wide range of threats that put information systems at risk, we must bear in mind the three basic computer security principles.

First principle: the intruder to the system will use any means or gadget that makes his access and subsequent attack easier.

The expression “any means or device” implies the existence of an enormous variety, both of fronts through which an attack can be produced, and of modalities, due to how they are produced, which includes actions of Social Engineering. This variety of methods and means makes risk analysis very difficult, although a clue to start. It is that: the intruder will always apply the philosophy of searching for the weakest point.

Second principle: data should be protected only until they lose their value

This principle implies the expiration of the protection system. In other words, there is a time interval during which the confidentiality of the data must be maintained, after which it is no longer necessary.

Third principle: control measures are implemented to be used effectively, and they must be efficient, easy to use, and appropriate to the environment.

This principle implies that control measures must work at the right time, optimizing system resources and going unnoticed by the user. It should also be noted that the effectiveness of any control system cannot be verified until the time comes when it is necessary to apply it.

Information Security Objectives

To minimize the above threats in information security, an appropriate set of specific controls must be implemented. These controls typically include policies, processes, procedures, organizational structures, and software and hardware features. It is also essential to use tools that allow the installation of information systems to be analyzed and organized, establish work procedures to define security, and have controls that will enable the effectiveness of the security measures implemented to be measured. All this must occur within a framework of continuous improvement, in which these measures are in a permanent state of review and revision.

The main objective pursued by the framework of information security controls is to protect the confidentiality, integrity, and availability of information and data, regardless of how they can be obtained.

  • Basic Principle of Confidentiality: compliance with this principle attempts to prevent unauthorized disclosure of the organization’s information, whether intentional or not. Confidentiality ensures that only authorized people can access information, preventing the spread of information to unauthorized people.
  • Basic Principle of Integrity: The property seeks to keep the data free from unauthorized modifications. The integrity of a message is obtained by appending another set of integrity check data to it. An example would be the digital signature, which is configured as one of the fundamental elements of information security.
  • Basic Principle of Availability: availability ensures that access without interruptions to data or information resources by authorized personnel occurs correctly and in real-time. That is, availability ensures that systems work when they are needed.

What Is Logical Security?

Within information security, logical security refers to safety in the use of systems and software. It also implies the protection of data, processes, and programs and the orderly and authorized access of users to information.

With logical security, the following objectives are pursued :

  • Restrict access to programs and files to authorized users only.
  • That operator can work without close supervision, but they cannot modify programs or files that do not correspond.
  • Check that the correct data, files, and programs are being used in and by the proper procedure.
  • Guarantee that the transmitted information is received only by the recipient and no other individual.
  • Ensure that the knowledge that the recipient has received is the same as that which has been transmitted.

Logical Security Policies

From a practical point of view, logical security policies are the means of control used to achieve the above objectives. The rational security policies of an organization are usually articulated through the following key elements:

Access controls. Access controls can be implemented in the operating system, in the information, in the databases, in a specific security package, or any other utility. It is usually the first line of defense for most computerized systems, its purpose being to prevent unauthorized persons from accessing them. They are the basis of almost all subsequent controls since it also allows you to track the activities of each of the users.

Roles, In this case, the access rights are grouped according to a specific position. Correspondingly, the use of resources is restricted to persons authorized to assume the said role. The use of parts is a relatively effective way of implementing access control. The role definition process is based on rigorous prior analysis of the organization’s behavior.

Transactions

It is articulated when the system knows the account number that provides a user with the relevant access in advance. This access has the duration of a transaction. When it is completed, the access authorization ends, leaving the user unable to continue operating.

Limitations to the services

The limitations to the services are controls that refer to the restrictions that depend on parameters specific to the use of the application. It also refers to those that the system administrator has preset.

Access

mode When specific access is allowed, it is also necessary to consider what type of access or mode is permitted. The four classic access modes that can be used are: read, write, execute, and delete.

Location and Time

Access to specific system resources may be based on data or people’s physical or logical location. As for the schedule, the use of parameters such as office hours or day of the week is expected when this type of control is implemented, which allows users to limit access to specific dates and times.

Internal Access Control Internal Access

Controls determine what a user (or group of users) can or cannot do with system resources. The main internal access control methods are:

  • Keywords (Passwords): the keywords or passwords are commonly associated with user authentication. Experts are also used to protect data, applications, and even PCs.
  • Encryption: encrypted information can only be decrypted by those with the appropriate key
  • Access control lists: these lists refer to a registry of users and the types of access that have been provided.
  • Limits on the user interface: Commonly used in conjunction with access control lists, these limits restrict users to specific functions. They can be of three types: menus, views on the database, or physical limitations on the user interface.
  • Security labels are denominations given to the resources (it can be a file). The labels can be used for various purposes: access control, specification of protection tests, etc.

External Access Control External Access

Controls are a protection against the interaction of our system with systems, services, and people external to the organization.

  • Port Control Devices – These devices authorize access to a specific port on the host computer and may be physically separate or included with another communications device, such as a modem.
  • Firewalls or security gates: firewalls allow you to block or filter access between two networks, generally one private and the other external (for example, the Internet), understanding a remote network as one “separate” from others.
  • Host-Based Authentication: Provides access based on the ID of the Host from which the access request originates, rather than based on the ID of the requesting user

The interest in cybersecurity is increasing, but betting on it to prevent attacks and unexpected threats is still something pending in many companies.

Cybersecurity is the set of tools, policies, security measures, and technologies aimed at protecting information assets and users of an organization from malicious attacks or threats in the cyber environment, ensuring that security properties are achieved and maintained ( availability, integrity, and confidentiality) thereof.

Information is power, and as such, it is one of the most critical assets that must be safeguarded in any company, regardless of its size. And this fact acquires capital importance since the Internet is the center of everything, and most of the operations and data exchanges are carried out using the Network of networks and through various devices connected to it.

It is in this context of cloud technologies (Cloud ), Big Data and the Internet of Things where cybersecurity has become an urgent challenge for the business world and a priority to guarantee the protection of sensitive information and also that of computer equipment and other devices or objects with connectivity sensors, where it is stored, and through which it circulates.

Data of Interest

Computer attacks that are carried out to steal valuable information on the Internet are becoming more frequent because hackers can detect security breaches without significant problems. 

Any business sector can suffer attacks, but the most common ones occur in:

  • The banking sector: to obtain bank information, user passwords, account numbers…
  • The tourism sector: mainly hotels and travel agencies suffer from them, due to the amount of data they keep on customers (personal and economic)
  • Healthcare: All patient data is collected and is often critical confidential information.
  • The audiovisual sector: movies to be released or musical albums pending publication have a great value to be sold.
  • Social networks: the last affected and, therefore, will close its version for the consumer or user, is Google +, which due to a software failure, exposed the private data of around half a million accounts.

This reality focuses on the need to invest in comprehensive cybersecurity plans urgently. Failure to do so can be costly and cause enormous damage to a company. We are not only speaking at an economic and reputational level, but also in terms of the trust of customers, partners, collaborators, or suppliers, to the extent that they are all part of the same universe, that of relationships and commercial transactions on the Internet, and also can be affected.

To develop a security policy, you have to follow four steps:

  • Define a series of rules and procedures for each company service.
  • Specify what actions will be carried out and select the people to contact if a possible intrusion is perceived.
  • Train those responsible for techniques to secure the system.
  • Familiarize workers with the problems linked to the security of computer equipment and make them aware of the existing risks.

Even though there is an increasingly clear perception of the risks that the digitization of companies entails, a high percentage still does not adopt any cybersecurity measure to prevent any computer attack.

How protected is your company? If you think it is vulnerable and may be attacked, it is time to act. Knowing the risks, detecting them, and keeping cyber threats at bay to protect sensitive company information should be your priority.

Social engineering is currently one of the significant threats to IT security, and the recent attack on Twitter made it clear again. Security expert CyberArk names five simple measures that significantly reduce the risk of social engineering.

The hacker attack on Twitter, which affected presidential candidate Joe Biden, ex-President Barack Obama, and Amazon boss Jeff Bezos, is one of the most significant attacks on a social media platform to date. According to Twitter, it is due to social engineering. The attackers could obtain privileged access data to an administrative tool that is usually only available to internal support teams.

People make mistakes, so companies will never rule out successful social engineering attacks entirely. But there are five measures a company can take to reduce the attacker’s success rate massively.

Awareness Building

Regularly raise employees’ awareness of security threats and ongoing training on cybersecurity best practices. In particular, attention should be drawn to the risks associated with money orders or the forwarding of confidential and personal information.

Use Of Privileged Access Management

One of the best proactive ways to minimize the risk of privileged access is to implement the least privilege principle within privileged access management. This means that the access rights of users should be restricted to the minimum necessary for the respective role. This can prevent an attacker from moving sideways in the company network – even after a successful social engineering attack.

Use Of Multi-Factor Authentication

One-factor authentication, for example, with a password, is always a single point of failure. Therefore, multi-factor authentication should be mandatory for access to critical systems, and this means that every social engineering attack comes to nothing.

Use of Dual Control Systems

No employee should have full access to confidential platforms without multiple levels of security. At least a four-eyes principle must apply. An employee only receives access to a critical system if they have received approval for this from a second authorized user or additional system logic (e.g., a ticket management system).

Monitoring Privileged Activities

The continuous monitoring of privileged sessions and analysis tools enable the automatic detection of risky behavior or unusual activities. Based on this information, a company can quickly initiate the necessary measures.

We are starting today with the topic of firewalls, explaining what a firewall is and what you should consider when using it.

What Is a Firewall?

A firewall can be described as a barrier protecting entire networks and separating network areas from harmful data traffic and hacker attacks. The network firewall is installed at the border between two networks. This boundary is usually between the World Wide Web and the company network. There are also so-called client firewalls that are installed stationary and only protect the end user’s computer.

Firewalls exist as hardware and software versions. All incoming and outgoing data traffic is examined by the firewall and checked using specific previously configured criteria. Data traffic is permitted if it meets the requirements set. If not, the traffic will be blocked. The data traffic is filtered based on the following criteria:

  • Address filtering: source, destination addresses, and port numbers are checked
  • Protocol filtering: the type of network traffic is limited, e.g., HTTP or FTP
  • The attributes or the status of sent information packages are also checked

The importance of a firewall seems to have arrived: “All of the companies surveyed use virus scanners, firewalls and password protection for computers and other communication devices,” says the press release on the study. However, firewalls do not automatically offer the necessary protection; it depends on the configuration.

The answer to the question of how to properly configure a firewall is constantly changing. It is worthwhile to have the company’s firewall professionally audited. If you have any questions on the subject, please do not hesitate to contact our trained security experts. Why are regular exams practical? Applications, users, and new devices can be added, access authorizations change with the distribution of tasks and roles in companies, clouds, and mobile devices are introduced. Firewalls are valuable for protecting stationary IT and monitoring applications in the network, in the cloud, or on mobile devices. In addition to changes to the existing IT landscape, changes in the threat environment also make regular checks and adjustments necessary. If this does not occur, rules that have been set can deviate enormously from the actual protection requirement, which opens the door for attackers to spy out confidential data. How often tests are required depends mainly on the risk situation and changes in the existing IT.

It is essential not only to compare the configuration of the firewall with reality regularly. The firewall logs are also ideally protected. This means that records are encrypted and audited according to the four-eyes principle and stored with as little data as possible.

Different Firewall Approaches

Firewalls can follow different approaches: the most straightforward implementation would be the packet-filtering router. Various packet filters are configured on the router, which controls the data traffic with the sender, destination addresses, and port numbers. Common IP routers work with this method as the standard. Forging an IP address, which is easy to implement, is enough to gain unauthorized access. Because it is a straightforward process, it is also relatively inexpensive and unsafe if you do without further measures.

If you connect a firewall system between two packet-filtering routers, the “bastion host” process is created. An external router is responsible for filtering the IP traffic between the bastion host and the Internet; an internal router only allows IP traffic between the internal network and the bastion host. The protection is very efficient and expensive since a firewall system is required in addition to two routers and the configuration effort is relatively high.

Many companies find a well-administrable and efficient solution with a firewall server. Because this master these functions: internal and external firewall router, bastion host, and Internet application server. A complete solution has thus been found that includes all servers for all relevant Internet services. Several methods of filtering and controlling access ensure that a high level of security is achieved.

Attack Scenarios Against Firewalls

Break-ins apply to the most common attack scenarios: attackers use the foreign computer for themselves. This means that user data, IDs, and files can be spied on and manipulated. Break-ins very often go undetected; Attackers can sneak their way through without a trace. The paralyzing of service is also a common scenario: other users should be prevented from using a specific computer or port. This form of electronic sabotage can destroy data and cause the device to fail. Most attacks of this type are staged with information overload, which means that the intruder overloads the system or network with network inquiries, messages, or other processes to such an extent that the user can no longer work effectively. It would also be conceivable.

Unfortunately, usernames, passwords, and IDs are often transmitted unencrypted in clear text, which means they can be intercepted within the network. Attackers also use this to steal information. Network technologies such as the almost ubiquitous Ethernet or Token Ring make the entire network very audible in the local network. As with break-ins, attackers often leave no trace, so information theft is seldom discovered.

Check The Firewall

Although every company has different risks to cover, there are some general guidelines for configuring and widespread firewalls. This involves first finding a formal process to test and approve the settings of the firewall. In this process, the above changes to the IT landscape should be taken into account. When configuring the firewall, you should also assign minimum access and connection authorizations—the smaller the circle of access, the lower the potential risks.

In addition to the firewalls for your networks, consider firewalls for applications, clouds, and mobile devices. When checking, please check whether the respective firewalls are active and whether the configurations are correct – the development of a formal process helps here. If changes to the rules and regulations are made to the firewalls, these must be revision-proof, justified, and, last but not least, documented. Firewall checks should occur very regularly, and ideally, the logs are evaluated according to the four-eyes principle.

If you use firewall audit tools, please check whether the agency could optimize the firewall configuration. Also, check whether the device supports all firewalls that you use in the company. You should ideally contain the structures of such a tool in a test environment. Are incorrect settings reported? Do the tool match the hardware and software firewalls used? Can you draw any meaningful conclusions from the log files? And do you keep these reports tamper-proof?

Clean Up The Firewall Rules

As you can see from the previous information, the set of rules of a firewall is one of the most critical points. It is essential to clear out the rules regularly and to adapt them to current circumstances. We cannot know your current situation, but there is also some general information for clearing out the rules catalog, which we would be happy to present to you. Over time, many regulations accumulate, and performance can suffer, primarily when several administrators work on the same firewall. Maintenance is made more complex, and security risks increase. There are essential rules for an online shop operator, such as the PCI-DS standard, which requires you to remove unnecessary restrictions and objects. The following best practice approaches will help you clean up your firewall and router rules; You can work through all points manually. If you use software to manage the configuration, most things will take place automatically:

“Shadow” – & delete new rules: Contradicting rules are referred to as “shadow” and have no effect whatsoever. The same applies to unused or expired rules. Delete this.

  • New connections: If source/destination/service routers are entered that you are not using, delete them.
  • Naming rules: Record the naming of the rules and keep them so that everyone can understand the rules. Use logical formats, for example, “computer name” _IP for your hosts.
  • Duplicates: delete object or rule duplicates, e.g., services or hosts that appear several times under different names.
  • Long rule sets: Get used to breaking long rule sets into legible pieces. For example, set a maximum of 20 rules per ruleset. It is also essential to reduce the complexity of a group of controls by ensuring that regulations never overlap.
  • Documentation: Rules, changes, names, and objects are documented, including their use, and stored securely.
  • Zone-based compliance policy: after you have defined the guidelines, check them using an audit report.
  • Priority of the set of rules: Frequently used rules should be sorted from the top. Many firewalls process packets using appropriately optimized algorithms so that the order does not matter. If yours is not one of them, you should sort the rules by priority to ensure clarity.
  • Separation of firewall and VPN: if you separate your firewalls from VPNs, the VPN processing does not bring the performance of your firewall to its knees.
  • Current software: New versions often get security and performance advantages, but sometimes also new functions, so there is not always an increase in performance. So that attackers cannot exploit old loopholes, make sure that your firewall is up-to-date.
  • Interfaces: The firewall interfaces are matched to the switch and router interfaces. Means: if your router works half-duplex, your firewall should also be configured to half-duplex. The firewall and switch ideally report the same duplex mode and the same speed.

Firewall Failure – What To Do?

The best and most transparent rules are of no use if the firewall fails – failures can last from minutes to hours. To be prepared, take appropriate precautions: it may not be enough to have a replacement device available if the firewall fails, but this replacement must start automatically in the event of a failure. For example, you can have one firewall configured and active while another is a standby firewall. Connect the two devices with a failover cable – an appropriately modified serial link cable is sufficient here. Configure so that both firewalls send messages to each other at a specified interval, roughly every few seconds. If communication remains unconfirmed, require further communication attempts. If these also remain unanswered,

Coupling the firewall with a monitoring module is also advisable. This ensures that the content to be blocked is blocked. Integrate alarm mechanisms that notify you of any irregularities and errors.

The Firewall: Conclusion

Firewalls are essential to protect your online shop from manipulation, access, and espionage. Due to the possibility of distributing access rights, firewalls safeguard against any unauthorized access from both inside and outside. Unwanted traffic is blocked so that the firewall also protects your systems from malware. In summary, it can be said that a firewall ideally …

  • controls access to the Internet and network,
  • secures the data traffic for incoming and outgoing connections,
  • applications proactively maintained,
  • protects privacy and
  • alerts you to activities that deviate from the routine and are therefore suspicious.

A firewall is undoubtedly part of essential protection but cannot guarantee security on its own. study mentioned at the beginning shows, all of the companies surveyed use a firewall. However, just activating the firewall is not everything: the configurations must be individually tailored to your risks and your IT landscape. Thanks to the firewall, if you check and log in regularly, your online shop is considerably more secure.

Large companies are affected by DDoS attacks, and they are also widespread among gamers. If you’ve been hit by such an attack yourself, you know how annoying it can be. Here we explain what DDoS attacks are and how you can protect yourself from them in the future.

What Are DDoS Attacks?

The abbreviation “DDoS” stands for “Distributed Denial of Service” in German for “decentralized denial of service.” It is an attack on an IP address, or a server in which many requests are sent until the connection is overloaded and no longer works, and it can, therefore, no longer respond to any further authorized requests from PCs.

What Do Hackers Use DDoS Attacks For?

There are several reasons why hackers launch DDoS attacks. If the attacks are carried out on the servers of large companies, the aim is usually to extort a ransom. After all, it is associated with significant losses for many of them if their online offer is suddenly no longer accessible. The companies are blackmailed into paying the attackers money to stop the cyberattacks. Logically, large online shops are usually affected by DDoS attacks.

However, it is also catching gamers more and more often, especially those involved in esports and online gaming. In video games in particular, who wins is often decided in fractions of a second, and the attackers take advantage of this. They disrupt the connections of individual players or entire teams through DDoS attacks to secure advantages for themselves. There are even services on the internet that will take over the DDoS attacks for you. That means you don’t necessarily need technical know-how for this.

Can a VPN Protect Against DDoS Attacks?

If you are now wondering: “What is VPN anyway?” Here is a brief explanation: If you use a VPN service, your data traffic is routed via the servers of the corresponding VPN provider for example diebestenvpn . Good providers work with many servers that are distributed all over the world so that there are always several suitable ones available for each user. The main goal of a VPN service is to maintain the users’ anonymity and protect their online activities from strangers. 

But how can a VPN protect a gamer from DDoS attacks?

Users remain anonymous

Most people choose a VPN because their IP address is obfuscated as the traffic goes through the VPN server. If someone wants to attack you with a DDoS attack, they need your IP address, and they cannot access it. 

VPN services do not save any user data

Of course, one or the other hacker comes up with the idea of ​​getting the required data of a user directly from the VPN provider. However, in most cases, these do not save any data on their users. This means that even if a hacker should manage to compromise a VPN service, he will not find any IP addresses or the like of users there. 

Protection against malware

Many VPN services also protect you from viruses and malware simultaneously. In this way, you are also safe from misusing your computer to carry out DDoS attacks on others. 

Protection against security holes

Another feature that many VPN services bring is security measures that allow criminals to get at a person’s IP address. 

Secure encryption of data

All data transmitted via a VPN server is encrypted using a reliable security protocol, making it impossible for hackers to intercept relevant personal information. 

Exceptional protection against DDoS attacks 

One might now think that a VPN is not of much use if your IP address cannot be attacked, but the VPN server can. VPN services are very well protected against such attacks. After all, one of their tasks is to make as many servers as possible available to their users around the clock. 

Availability of many servers

The many servers that a VPN service offers are another reason for adequate protection against DDoS attacks. Should a hacker succeed in launching an attack on a VPN server, you can easily switch to another. There are often thousands of servers available all over the world. 

Conclusion

Of course, you don’t necessarily need a VPN like internetbeskyttelse if you are a gamer, but apart from protection against DDoS attacks, it brings you many other advantages when gaming. For example, you can handle geo-blocking and still purchase games that are not yet available in your country. The fact that you can choose servers from different countries makes playing with friends from all over the world much more accessible. The encryption of all your online activities also protects you from bandwidth throttling by your internet provider.
