Digital Rights Management (DRM) is a technology that is used to control the use and distribution of digital content, including music, movies, e-books, and software. The primary purpose of DRM is to ensure that digital content is only used in ways that are authorized by the copyright owner. DRM technology works by placing restrictions on the use of digital content, which are then enforced through encryption, digital signatures, or other methods.

DRM systems typically involve the use of software that is integrated with the content. This software is designed to control how the content is used and to prevent unauthorized access to the content. DRM systems can also be integrated with hardware devices, such as DVD players or e-book readers, to ensure that the content is only used in authorized ways.

One of the most common methods of implementing DRM is through the use of encryption. When digital content is encrypted, it is transformed into a code that cannot be understood without a key. The key is typically stored on a server, and it is used to decrypt the content as and when it is needed. DRM systems can also use digital signatures to authenticate the content and to ensure that it has not been tampered with.

DRM systems are designed to be flexible so that they can be customized to meet the needs of different types of digital content and different types of users. For example, a DRM system for music may allow users to play the music on a limited number of devices, while a DRM system for software may allow users to install the software on a single device.

DRM technology is utilized to protect a wide range of digital content, including entertainment media such as books, music, and videos, as well as sensitive business data, database subscriptions, and software programs. DRM helps content creators and copyright holders control how their work is used and prevent unauthorized changes or misuse.

Here are some examples of DRM in action:

iTunes. Apple's iTunes store uses DRM to limit the number of devices customers can use to listen to songs. The audio files purchased from iTunes contain information about the purchase and usage of the songs, which prevents access from unauthorized devices. Additionally, the content in the iBooks store is protected by FairPlay technology, which ensures that books can only be read on iOS devices.

Digital Music. Spotify uses blockchain technology and DRM to identify songs played and pay the right artist through cryptocurrency. The music streaming company acquired Mediachain to assist in this process.

Microsoft Software. before downloading Microsoft software, such as Windows or Office, users must accept the company's user license and enter a key. Microsoft also uses a kind of DRM technology called PlayReady to secure the distribution of content over a network and prevent unauthorized use of its software.

Sensitive Documents. Many organizations use DRM to protect business-critical documents and sensitive information, such as confidential employee data, business plans, and contracts. DRM allows organizations to track who has viewed files, control access, and manage usage, as well as prevent alteration, duplication, saving, or printing.

Regulatory Compliance. DRM is important for organizations to comply with data protection regulations, such as HIPAA for healthcare organizations and CCPA and GDPR for all organizations.

Despite the benefits of DRM, there are also some criticisms of the technology. Some users argue that DRM restricts their ability to use digital content in ways that they feel are reasonable and legitimate. For example, they may feel that they should be able to transfer a purchased song from one device to another or to make a backup copy of a digital book.

Additionally, DRM systems can be vulnerable to hacking and other forms of attack. If a DRM system is compromised, it can allow unauthorized access to the content, which can undermine the purpose of the DRM system. This has led some users to view DRM as an unnecessary restriction on their ability to use digital content and as a threat to their privacy and security.

Another criticism of DRM is that it can make it difficult for users to access their digital content in the future. For example, if a user switches from one device to another, they may find that their DRM-protected content is not compatible with their new device. Additionally, if the company that provides the DRM system goes out of business or discontinues support for the system, users may be unable to access their content.

Despite these criticisms, DRM remains an important tool for protecting the rights of copyright owners and for ensuring that digital content is used in authorized ways. DRM systems have been used by a wide range of companies, including music labels, movie studios, and software publishers, to control the use and distribution of their digital content.

In recent years, some companies have started to move away from DRM, recognizing that it can be a barrier to the adoption of digital content. For example, some music labels have started to offer DRM-free music downloads, recognizing that users are more likely to purchase music if they are not restricted in their ability to use it. Additionally, some e-book publishers have started to offer DRM-free books, recognizing that users may be more likely to purchase books if they are not restricted in their ability to use them.

However, despite these trends, DRM remains an important tool for many companies, especially for those that want to ensure that their digital content is used in authorized ways. DRM is particularly important for companies that are concerned about piracy, as it can help to prevent unauthorized copying and distribution of their content.

In conclusion, DRM is a technology that is used to control the use and distribution of digital content. DRM systems work by placing restrictions on the use of digital content and enforcing these restrictions through encryption, digital signatures, or other methods.

While DRM has its benefits, including the protection of the rights of copyright owners, it also has its criticisms, including restrictions on the use of digital content and the potential for hacking and other forms of attack. Nevertheless, despite these criticisms, DRM remains an important tool for many companies and is likely to continue to be used in the future.

The most up-to-date personal computers have the ability to instantly recognize whether a wireless connection is present. But what if you don’t want to go through the effort of unpacking your laptop, starting it up, logging on, and then strolling about with it just to discover that there is no wireless network coverage in the area where you are? Because of this, having a WiFi sniffer on hand may be quite helpful in assisting you in rapidly locating the nearest WiFi network.

What is a WiFi sniffer?

A WiFi sniffer is a portable instrument that can locate the wifi network that is closest to the user. In addition to this, it will assist you in determining the strength of the WiFi signal, and if there are many signals, a WiFi sniffer will prioritize the signals in terms of their strength, which will save the user both time and annoyance.

WiFi sniffers are available in a variety of device formats, either as a stand-alone appliance or as software add-ons that interact with your wireless mobile device. You may get a WiFi sniffer in any of these two ways. The add-ons may often be obtained through the service provider of your mobile device, although standalone WiFi sniffers can be purchased at any store specializing in the sale of computers or electronic goods.

WiFi sniffers are able to handle all kinds of wireless network cards and come included with a Prism2 driver that may assist you in determining the intensity of the signal. WiFi sniffers are developed using C++ programming and operate using an "n-tier" structure. The gathering of data begins at the lowest tier and progresses up to the topmost layer, which is where the user interface is placed.

How does a WiFi sniffer work?

The operation of a WiFi sniffer does not call for a significant amount of technical expertise and may be carried out with relative ease. If you are using the standalone device, which is compact and portable, all you need to do is push and hold down the main button, aim it in any direction where you wish to locate a wireless network, and then use the gadget. This will activate the gadget, and while it is looking for a signal, the device will display lights that revolve in a circular pattern. The indicator light will remain constant after it finds a wireless signal. This means that it has detected a wireless network that is within a range of 300 feet of your device.

In the event that a signal cannot be found, the rotating lights will continue to do so, and it may be required to attempt to look in a different direction. If you are in an area where the wireless signal is poor, it is possible that it may be necessary to make adjustments to the antenna. WiFi sniffers that are add-ons to your mobile device do their functions in a manner that is analogous to that of the standalone device. Nonetheless, their specific capabilities change depending on the sort of mobile device that you are utilizing.

No. Stumbling across a wireless network by using a WiFi sniffer is a much simpler process than wireless sniffing, as the two terms refer to quite distinct activities. A WiFi sniffer's sole purpose is to discover the location of the nearest accessible wireless connection; however, it cannot actually join the network itself. Eavesdropping on conversations taking place inside of wireless networks is what's known as wireless sniffing, and it's a technique that's intended to break into a network. The former is permitted but the latter is not, particularly when it is utilized in the commission of illegal conduct.

On the other hand, wireless sniffing is entirely within the law when it is employed by IT employees to monitor network incursions on a business or government infrastructure. This is the case whether the infrastructure is owned by a private company or the government. Monitoring the information packets that are sent over a network is what's referred to as "intrusion detection," and it's used to protect sensitive data from being stolen by hackers and other malicious users of the internet.

There are a few businesses that have made it illegal for customers to use WiFi sniffers, which are devices that randomly search for available wifi networks. Instead, corporations are deploying apps that are based on directories and that can be allowed for usage by mobile employees as well as other people.

Hopefully, the material presented here will assist you in gaining a deeper comprehension of WiFi sniffers and the functions they perform. In short, they’ll help you save time and stress while maximizing the signal strength of your home wireless network.

It is also compatible with third-party security extensions.

Firefox's anti-phishing protections are impressive, as it is highly effective in detecting risky and known phishing sites when tested against a database of such sites. Additionally, Firefox's DoH protections encrypt search queries with CloudFlare or NextDNS's encrypted DNS servers, making it challenging for third parties to steal browsing history.

Although many highly secure browsers compromise convenience for protection, Firefox is simple to use and provides advanced security features. Users can adjust security settings, anti-tracker settings, and anti-phishing protections according to their preferences. Firefox is compatible with Windows, macOS, Android, and iOS.

Tor Browser

In terms of user privacy, Tor Browser is the top choice; however, it is not as fast as most of its competitors.

The name "Tor" is derived from "The Onion Routing," a technology that hides the user's IP address by encrypting web traffic and routing it through multiple servers. As a result, before a user's computer can access a website, their traffic must first pass through Tor's secure server network. Tor has been shown to conceal user activity from ISPs, hackers, trackers, and even governments. The NSA was reportedly unable to hack into the Tor network, as stated in Edward Snowden's leaked documents. Tor Browser is banned in certain countries that censor the internet because it provides users with unrestricted access to the web.

Tor's data collection policy is minimally intrusive, as it only collects usage data to assess browser performance. Despite being an advanced browser, Tor Browser's interface is user-friendly, and it uses the same source code as Firefox, with minor variations. Users can even install most Firefox extensions into Tor Browser. However, browser extensions increase the likelihood of machine identification by network surveillance tools, so users who wish to remain as private as possible should avoid using them.

While Tor Browser is highly secure, its onion routing technology will slow down the internet connection, similar to the effect of using a VPN. When users' traffic bounces off multiple servers, their connection speed is adversely affected. Nonetheless, Tor may be the ideal choice for users with a reliable internet connection who is willing to trade some speed for high security. Tor Browser is compatible with Windows, Android, macOS, and Linux.

Brave

Brave is a web browser that offers a fast browsing experience and comes with built-in ad and tracker-blocking features. With its "Shields" feature, Brave can automatically block ads and trackers, which allows it to load websites much faster than other browsers. This feature also provides an added layer of protection by blocking malicious web scripts that may try to infiltrate your device. In addition, Brave automatically sets up HTTPS connections, which use a secure encryption protocol to protect user traffic.

One of Brave's standout features is its ability to use Tor technology in Private Browsing mode, which encrypts your traffic through the Tor network. This ensures that your browsing activity remains hidden not only from other users on your device but also from your ISP and other network spies.

Brave also has a unique ad-buying program called Brave Rewards, which allows users to earn BAT (a type of cryptocurrency) by viewing or clicking on sponsored ads. These BATs can then be transferred to the sites and content creators of your choice. This program offers a great revenue solution for content creators as Brave ads generate revenue without using trackers, selling user data, or pop-ups that interrupt the browsing experience. Brave is available for Windows, Android, iOS, macOS, and Linux.

Google Chrome

The reason why Google Chrome is the most popular browser in the world is that it is compatible with all major platforms and provides users with an excellent interface as well as thousands of useful extensions. Google, with its large number of staff and resources, constantly updates and patches Chrome more quickly than any other browser developer to patch network vulnerabilities, man-in-the-middle attacks, browser glitches, and exploitable security holes.

Chrome's Safe Browsing feature uses Google's extensive database of unsafe sites to flag suspicious web pages, which is updated daily and detects more phishing sites than most other browsers. Additionally, Chrome uses sandboxing to prevent malicious web scripts and invasive trackers from stealing data or hacking devices. Users can choose DNS over HTTPS (DoH) protection in Chrome's settings for added privacy and protection from ISPs, governments, and network-snooping hackers, which is turned on by default in Firefox but only requires a single click in Chrome.

It's important to mention that Chrome's tracker blocking is limited due to Google's reliance on web trackers to gather user data for advertisers. Chrome collects user data by default, and while much of this data is used to enhance Chrome's security, it's also shared within the entire Google ecosystem, including advertisers and potentially even governments. Despite this, Chrome has many trackers and ad-blocking plugins available for security-oriented users, such as Avira Safe Shopping. Although Chrome may be one of the most secure browsers, it's also one of the worst for user privacy. Google Chrome is available for Windows, macOS, Android, iOS, and Linux.

Microsoft Edge

Microsoft Edge is a vast improvement compared to its predecessor, Internet Explorer. Edge is a user-friendly, Chromium-based browser that boasts robust security tools, including Edge SmartScreen anti-phishing technology, which detects phishing sites more effectively than Chrome in tests.

In addition to its security features, Edge also offers a simple tracker-blocking system that has three levels: Basic, Balanced, and Strict. The Strict setting blocks most trackers and cookies, including those necessary for some sites to function. In contrast, the Balanced setting performed best in tests, detecting and blocking the most invasive cookies. This makes it much easier to manage online privacy than in Chrome, where the options are limited to

"Allow All," "Block Third-Party," and "Block All."

Like Chrome and Firefox, Edge now supports DNS over HTTPS by default, which enhances user privacy when browsing the web. Microsoft Edge is available for Windows, macOS, Android, and iOS.

Conclusion

It can be difficult to determine whether a browser is truly secure or not, but the browsers mentioned in this article offer a good level of privacy. While this is a great start, for the most secure browsing experience, I suggest using a combination of a secure browser and a virtual private network (VPN). A VPN adds an extra layer of protection to your online activity by encrypting your entire Internet connection, making it much more difficult for anyone to intercept your data or monitor your browsing habits.

By using a quality VPN, you can also hide your real location and appear to be browsing from a different location altogether. This can be especially useful for accessing content that may be restricted in your country or region. With a secure browser and a VPN, you can enjoy a more private and secure browsing experience, free from the prying eyes of hackers, governments, and other third parties that may be trying to track your online activity.

In an era where cybercrime is rampant, businesses must take a proactive approach to safeguard their confidential information. In 2021 alone, over 118 million people have been affected by data breaches, and this number is expected to rise exponentially.

In this post, we’ll discuss some of the best practices for businesses to protect themselves from cyber threats.

Always have a back-up

A good backup system is one of the best ways to maintain computers’ security and protect your business’s data. Regularly backing up important files can help ensure that you don’t lose any information if a cyber incident or computer issue occurs. Here are some tips on how to effectively back up your data:

• Use multiple backup methods. Have an effective backup system by using daily incremental backups to portable devices or cloud storage, end-of-week server backups, quarterly server backups, and yearly server backups. Remember to regularly check and test whether you can restore your data from these backups.
• Use portable devices. Consider using external drives or portable devices such as USB sticks to store your data. Store the devices separately offsite, and make sure they are not connected to the computer when not in use to prevent malicious attacks.
• Utilize cloud storage solutions. Cloud storage solutions are a great way of backing up all your important information. Choose a solution that provides encryption for transferring and storing your data and multi-factor authentication for access.
• Practice safe backup habits. Make it a habit to regularly back up your data, not just once but multiple times throughout the week or month, depending on the type of information you’re backing up. Additionally, it’s important to practice safe backup habits, such as keeping your devices away from computers when not in use and regularly testing that your data is properly backed up.

Train your employees

To protect your business from cyber threats, educating your employees about the risks and how to stay safe is essential. Training should focus on identifying phishing emails, using strong passwords, and reporting any suspicious activity immediately to the IT department.

Ensure that everyone is up-to-date with the latest threats and strategies for protection by conducting regular cybersecurity training sessions with all of your employees. Provide helpful resources such as tips for creating secure passwords, methods for spotting phishing attempts, and steps for safely sharing confidential information online.

Putting this emphasis on education and training will help create an environment of alertness so that any potential risk can be identified quickly and addressed appropriately.

Password management

Weak passwords are one of the most common entry points for cyber attackers, so using a secure password and password manager is essential to keep your business safe.

A password manager is a tool that allows you to store and manage all your passwords securely, with only one strong master password needed to access them all. Here are some tips for creating strong passwords and using a reliable password manager:

• Create strong passwords. Choose passwords that include numbers, symbols, upper-case letters, and lower-case letters. Avoid using personal information like birthdays or pet names in your passwords. Additionally, avoid using the same username/password combination for multiple accounts.
• Use a password manager. A reliable password manager will help you create and store secure passwords. Be sure to select a trustworthy provider, as they will be responsible for protecting your data.

An on-premise password manager like Passwork is an excellent option for businesses that need to store passwords on their own servers. Passwork provides the advantage of having full control over your data and features like password sharing and a secure audit log.

• Enable multi-factor authentication. Adding an extra layer of security to your accounts is easy with multi-factor authentication (MFA). MFA requires two or more pieces of evidence to authenticate the user's identity, such as passwords and biometric data. Most password managers can enable MFA for all your accounts, so be sure to take advantage of this feature.

Finally, make sure you update your passwords regularly and always keep them private. Following these tips will help ensure that you are protecting your business from cyber threats.

Securing your network

Using a Virtual Private Network (VPN) effectively protects your business's sensitive data and prevents unauthorized access to your network. A VPN creates an encrypted connection between your device and the internet, making it more difficult for hackers or malicious actors to intercept and access confidential information. Here are some tips on how to leverage a VPN for optimal security:

• Research the best VPN providers for features that best suit the needs of your organization
• Ensure that the provider meets industry standards such as AES 256-bit encryption
• Set up two-factor authentication with users’ login credentials
• Configure the VPN for reliable and secure connections
• Monitor your network for any suspicious activity or unauthorized access attempts
• Make sure to update the VPN software with new security patches regularly
• Train users on the proper internet safety and best practices when using a VPN
• Use an antivirus program and scan all devices connected to the network for malware threats

VPNs are not only important for protecting data and preventing unauthorized access but also for maintaining user privacy. By encrypting the data sent and received over the internet, your organization can ensure that any information stays secure and confidential.

Consistent vulnerability assessments are crucial

Organizations of all sizes must remain vigilant in mitigating cyber threats — and one of the best ways to do this is by conducting regular vulnerability assessments. This will help identify any potential weaknesses or vulnerabilities that could be used by malicious actors to gain access to your system, allowing you to patch and address them before they become a problem.

Here are a few steps to help get you started:

Develop an assessment plan for your organization

Before starting, it’s important to understand the scope and objectives of the vulnerability assessment. Define the overall goals and objectives before identifying any assets or systems that should be included in the assessment.

Identify and document threats

Once you have developed a plan, it’s time to begin searching for potential vulnerabilities within your system. You can use various open-source intelligence techniques, such as scanning public databases and researching known security issues with similar software versions or operating systems that are present in your system.

Create a testing environment

After potential threats have been identified and documented, you should create a safe testing environment to validate the vulnerability assessment results. Doing so will help ensure that any tests conducted do not adversely affect production systems.

Run automated scans

Following the creation of your secure test environment, it’s time to run automated scans on your organization's target systems or assets. This should include both internal and external scanning tools, such as port scanners, web application scanners, or configuration management tools, depending on the scope of the assessment.

Analyze scan results

Once the automated scans have been completed, it’s time to analyze the results and identify any potential issues or vulnerabilities. Assess any weaknesses present in order to prioritize and address them more effectively.

Develop a remediation plan

After identifying potential security issues, you should develop a remediation plan based on the risk level of each issue. This could include patching vulnerable systems, implementing new security measures, or restricting access to certain areas of your system, depending on the severity of the threat.

By conducting regular vulnerability assessments, organizations can stay ahead of cyber threats and ensure their systems remain secure.

Bottom line

Protecting your business from cyber threats should be a top priority for any organization. With the increasing prevalence of cybercrime and data breaches, implementing effective cybersecurity practices is more important than ever.

By regularly backing up important files, training employees on identifying and reporting potential threats, using a secure password manager, utilizing a VPN, and conducting consistent vulnerability assessments, businesses can significantly reduce their risk of falling victim to cyber-attacks.

In recent years, the issue of user privacy has become more critical than ever before. With the rise of social media and other online platforms, companies are collecting vast amounts of user data, which can be used for various purposes. While some of these purposes may be benign, such as improving the user experience or providing targeted advertising, others may be more nefarious, such as selling user data to third parties or engaging in targeted surveillance.

There are now many apps that are activated by code words — they are called " marker words". These words can activate the listening function on your gadget covertly and completely invisibly. It can be not only "OK, Google" or "Hi, Siri", but also other completely unrelated words or sounds.

Perhaps you may have noticed Instagram advertising something you recently talked to your friends about even in real-time without holding your phone. If so, you know you're being bugged.

So, who's eavesdropping on us?

Facebook

Facebook reportedly hired hundreds of third-party contractors to transcribe voice messages but stopped the practice in July 2019 after it was made public. The contractors were not always clear on why they were listening to certain conversations and did not understand how the messages were obtained. Facebook did not inform its users about this development, which involved the potential listening of personal voicemails by unauthorized individuals.

Microsoft

Microsoft's employees were reported to have listened to personal audio recordings made through Cortana and Skype Translator services. However, Microsoft did not deny this claim and instead included the information in the company's privacy policy. Microsoft believes in maintaining an honest relationship with its users and believes they have the right to know that their conversations may be overheard. Nonetheless, Microsoft did not previously disclose this information to its users, and it is possible that the company decided to proactively share the information as they had been listening to audio recordings for some time. This is in contrast to other companies that faced privacy violations but did not disclose their actions to their users.

Apple

It has been reported that contractors who test Apple's Siri voice assistant for accuracy may be listening in on users' private conversations. It should be noted that Siri can be activated by more than just the phrase "Hey, Siri" and can be triggered by similar-sounding words, background noise, or hand movements. This has resulted in Siri being inadvertently activated during private conversations, leading to the collection of personal information and recordings of private conversations, including those between doctors during commercial transactions. These recordings are often accompanied by data that can reveal the location or personal contacts of the users. Apple representatives claim to be working to address these concerns in order to protect users' personal information.

Amazon

Over one thousand Amazon contractors are listening to voice recordings made in the homes and offices of Echo voice assistant owners. These contractors are required to sign non-disclosure agreements and are not allowed to discuss the program publicly. They work nine-hour shifts and analyze up to 1,000 sound recordings per shift, but even if they have concerns about what they hear, they are required to adhere to the non-disclosure policy. Amazon claims to take the security and privacy of its customer's personal information seriously, and employees do not have access to information that could identify a person or account directly. It is important to note that users can disable the use of their personal voice records for the development of new features in Amazon's Alexa privacy settings.

Google

Google employs experts to listen to the voice commands given by users to its voice assistant. These recordings are made after the voice assistant has heard the phrase "Ok, Google" and can be made on smartphones using Google Assistant or on the Google Home smart speaker. Google shares snippets of these recordings between users and linguists around the world to improve the voice assistant, but claims to have access to no more than 0.2% of all user commands. The company has prohibited employees from transcribing conversations or other extraneous sounds. However, in June 2019, it was reported that a significant leak of audio recordings of users occurred, with over a thousand recordings, including personal conversations between parents and children, addresses, and work calls being exposed. Some recordings were made accidentally due to the assistant being activated by mistake. Google attributed the leak to the actions of one linguist and claimed to be investigating the matter.

Conclusion

Despite the concerns that these data collection practices raise, companies often argue that they are necessary to improve user experience and provide more personalized services.

However, many users remain skeptical of these claims and are increasingly concerned about the potential for abuse. For example, data breaches can expose user data to hackers and other malicious actors, potentially putting users at risk of identity theft and other forms of cybercrime. Additionally, governments and other organizations may use user data to engage in targeted surveillance, raising concerns about civil liberties and individual privacy.

In response to these concerns, governments and regulatory bodies have taken steps to regulate the collection and use of user data. In the European Union, the General Data Protection Regulations (GDPR) have strengthened data privacy laws and given users greater control over their data. In the United States, the California Consumer Privacy Act (CCPA) has similarly sought to protect user privacy by requiring companies to disclose what data they collect and allowing users to opt out of data sharing.

Despite these efforts, however, the issue of user privacy remains a contentious one. As technology continues to advance, companies will undoubtedly find new ways to collect and utilize user data, raising new concerns about privacy and security. It is therefore crucial that users remain vigilant and informed about the data collection practices of companies they interact with, and for governments and regulatory bodies to continue to monitor and regulate these practices to protect user privacy.

People frequently utilize various VPN servers at work. Off-the-shelf options are good, but we've come to learn that a personal VPN offers substantial benefits. To appreciate the benefits of creating your own VPN server over purchasing one, consider why VPNs are used in the first place:

•  To prevent others from intercepting your lines of communication

•  To circumvent access limitations to a specific resource in your own nation or a foreign one

•  Conceal personal information from the Internet provider (the owner of the WI-FI access point)

•  Leave your present location unidentified (don't forget time zones — this is the indicator that may readily pinpoint your location)

Everything is quite straight-forward here, so let's get down to the interesting stuff: what are the advantages of utilizing your own service, and how should you go about establishing one?

Well, today you’re in for a treat — to answer these questions, we’ve put together a checklist with step-by-step instructions for setting up and configuring a VPN server.

Advantages of Using a Personal VPN Server

1. Bypassing blocks

Several countries attempt to fight VPNs by blocking them. But, if you use your own VPN, it will not appear in the main list of providers and will almost surely avoid blocks.

2. There are no captchas

All well-known services will request that you choose horses from a set of photographs, locate traffic lights, or identify a word in a picture. Why is this the case? Several others are using a ready-made VPN server at the same time as we are. Consequently, the website will suspect such traffic and assault you with captchas. When you use your own VPN server, however, this problem is avoided since you will have a unique IP address that will look like an ordinary user.

3. High speed

Off-the-shelf VPN servers often have low bandwidth since they typically don't have time to grow their servers and networks for a big number of customers. With a self-hosted resource, you’ll have all the bandwidth you could possibly need.

4. The ability to send all computer traffic through a VPN, not just browser traffic

5.  No need to install third-party software

As you can see, having your own server solves the majority of the problems associated with using a VPN.

Checklist for creating your own VPN server

Take the example of DigitalOcean and its Droplet server.

Registration

If you already have a DigitalOcean account, you may go to the next stage. If not, you must first register (all the steps are intuitive, don’t worry).

Create a new Droplet that will function as a VPN server

Choose a data center from which you intend to connect to the internet. I selected to work with Frankfurt since it is physically closer to my country of residency, which improves working speed.

Choose Marketplace, and Docker on Ubuntu in the Image column. Finally, in the Size column, choose the subscription plan that suits you.

Next, put a name in Hostname, such as ‘vpn-server’. This has no effect and is simply for your convenience. Next, click the Create Droplet button.

Wait for the server to be created. This might take up to a minute. Following that, you will be given your server's IP address.

Connect to the SSH server

Launch Terminal on MacOS/Linux (or PowerShell/putty on Windows) and connect to our server through SSH using the root username and the IP address of our server.

This can be done with the help of:

ssh root@{your-ip-address}

> enter your password

After that, you have to connect.

Create a docker-compose.yml file

Just copy the code from this website and paste it into your file. This is your server configuration file.

You may create a file directly over SSH using console text editors (nano/vim) or with an SFTP client. I used SSH to access the console editor.

In the same SSH window, input the following:

> nano docker-compose.yml

Paste the content. In the added text, change the following parameters for yourself:

•  my-shared-secret — your secret word

•  my-username — your personal login

•  my-password — your password

Take note of how straightforward it is — there are just 14 lines in the file that we want.

Exit by pressing Ctrl+X, then Y, and then press Enter.

Run the container with the recently created server

Use the same SSH window in which we just created the file.

> docker compose up -d

Congratulations! Your VPN server is up and running. So, how do you connect it?

Connect to the created VPN server

We recommend using IPsec because the clients for this VPN are already built into MacOS/Windows and you don't have to install anything locally. You just need to create a new VPN connection with the following parameters:

•  Type: IPSec

•  Server address: enter the IP address of the server

•  Account name: write my-username (or the one you changed it to)

•  Password: add my-password (or the one you changed it to)

•  Shared Secret: write my-shared-secret (or the variant you changed earlier)

For MacOS, you don't need to install anything, just configure it like this:

For Windows, these settings will look a little different:

Unfortunately, Windows is not so simple and you will have to surf the registry and allow NAT-T.

For Linux users, there is also a screenshot with the required settings (I used them in Ubuntu 22.04):

Before setting up, you need to install the network-manager-l2tp-gnome package. This is done through the console:

> sudo apt-get install network-manager-l2tp-gnome

You can also connect from your phone, you don't need to install anything else. The settings on the iPhone look like this:

And that’s it — you're done! Connect and check the IP address, for example, on Whoer via the link. Now, for the whole Internet, you are physically located in the region where you created your VPN server, and the IP is the IP of the server. It's not as scary, time-consuming, or expensive as you might think.

Security recommendations

When it comes to the security of your server, I would, as a final thought, recommend:

•  Using an SSH key instead of a password

•  Changing the SSH-port from 22 to any other

•  Using a complex password and Shared-secret (preferably a randomly generated string)
