In today’s world, information security and the stable operation of a virtual private server (VPS) are essential and constant concerns for any business. While Linux is considered one of the most secure operating systems, it is not immune to viruses and malware.
In this article, we’ll walk you through how to scan your Linux VPS for viruses and provide practical recommendations for keeping your server secure.
In today’s digital world, user security and protection of personal data have become critically important. One of the fundamental steps in safeguarding users is verification — confirming that you’re dealing with a real person, not a bot or a fraudster. The way you implement this process directly impacts both the security and usability of your website.
In this article, we’ll explore the three most popular verification methods — phone calls, SMS, and email — discussing their advantages, drawbacks, and suitable use cases.
In today’s digital world, web application security is critically important. One effective way to enhance protection is by using HTTP security headers, which help prevent various attacks by modifying browser behavior. Let’s explore the key security headers and their role in protecting your web applications.
Security headers are directives that enhance web application protection by creating additional barriers against vulnerabilities. They modify browser behavior to mitigate potential threats such as man-in-the-middle attacks or malicious content injections.
Ensures that browsers always use HTTPS to connect to websites, preventing potential attacks that downgrade the protocol to insecure HTTP.
Allows developers to control the sources of content that can be loaded on a page, reducing the risk of XSS (Cross-Site Scripting) attacks and other injections.
Determines whether a site can be embedded in frames on other websites, helping to prevent clickjacking attacks.
Enables built-in browser filters to detect and block XSS attack attempts.
Prevents browsers from guessing MIME types, reducing the risk of executing malicious scripts disguised as other file types.
Controls what referrer information is sent when navigating between sites, reducing the risk of confidential data leakage.
Specifies which domains can access your web application’s resources, which is crucial for API security.
Using security headers helps prevent various types of attacks, including:
To configure security headers, you need to update your web server’s settings. Below are examples for Apache and Nginx.
Add the following directives to your virtual host configuration file:
<VirtualHost *:443>
Header always set Strict-Transport-Security “max-age=31536000”
Header always set X-Frame-Options “deny”
Header always set X-XSS-Protection “1; mode=block”
Header always set X-Content-Type-Options “nosniff”
Header always set Content-Security-Policy “default-src ‘self'”
Header always set Referrer-Policy “strict-origin-when-cross-origin”
</VirtualHost>
Add the following directives to your server configuration file:
server {
add_header X-Frame-Options “deny” always;
add_header Strict-Transport-Security “max-age=63072000; includeSubdomains;” always;
add_header X-XSS-Protection “1; mode=block” always;
add_header X-Content-Type-Options “nosniff” always;
add_header Content-Security-Policy “default-src ‘self'” always;
add_header Referrer-Policy “strict-origin-when-cross-origin” always;
}
After applying these changes, restart your server to activate the new settings.
Using security headers is a crucial step in protecting your web application from various threats. Properly configuring these headers helps minimize the risk of successful attacks and increases user trust in your website.
Remember, security is an ongoing process. Regularly check and update your web application’s security settings.
Artificial Intelligence (AI) has become an integral part of the modern world of cybersecurity. As cybercriminals devise increasingly sophisticated attack schemes, AI evolves to swiftly detect threats, analyze data, and prevent potential dangers. But how exactly does AI protect our information? Let’s explore this together in today’s article.
In today’s world, where information is a key resource for understanding and perceiving everything around us, server security is becoming increasingly necessary.
Your own server can be a repository of valuable data, both personal and business, so protecting it from cyberattacks is an extremely important task today.
In today’s world, the internet is a boundless space of opportunities, but at the same time, it’s a place where fraudsters and cybercriminals lurk. Phishing is one of their deceitful methods, where they impersonate a legitimate organization or individual to steal your personal information. Thus, detecting phishing websites becomes an increasingly important element of online security to preserve your confidential information and protect it from scammers. Let’s take a closer look at phishing today and discuss several useful tips on how to recognize it and avoid the dangers it poses.
In today’s digital world, where cyber threats are becoming increasingly common, website security cannot be ignored and requires special attention. For example, WordPress, being one of the most popular content management systems, often becomes a target for hackers due to its popularity. However, by choosing the right hosting provider, you can significantly reduce the risk of malicious attacks. In this article, we will take a closer look at several ways in which hosting can protect your WordPress site and what to pay special attention to when choosing it.
In our time, when we share personal information and increasingly communicate with our relatives and close people through online resources, the issue of security and protection of confidential information becomes more relevant. Especially as the number of communication means and platforms for communication increases every year, as does the number of potential cyber threats.
So how do we now choose a secure messenger to keep our own data and private messages secret and away from prying eyes? Let’s talk about this in our article today and consider the most secure messengers for you and your loved ones.
In our digital world, information is one of the most important assets. It can contain vital documents, customer data, financial information, and much more. Thus, the loss of this information can cause serious harm to a business or personal life.
Backups are copies of important information stored separately from the main source. They are used for restoring data in case of loss, damage, or destruction of the primary source.
However, even in this process, it is important to consider security, namely the security of backups, which is a crucial component in protecting information from unauthorized access, alteration, or even destruction.
An SSL certificate is an electronic document that secures the connection between a web server and a user’s browser. It encrypts the data transmitted between these two devices, preventing interception and reading by third parties.
SSL certificates are an essential element of internet security. They are used on websites where users enter confidential information, such as passwords, credit card numbers, or personal data.
However, not all websites have this security certificate. Therefore, it’s important to check for SSL protection when visiting them. But how can you check if a website has an SSL certificate? We will tell you about it in this article.
