Imagine downloading a program from the internet. Your system shows a warning: “This file may be unsafe. The publisher is unknown.” You hesitate. Should you run it? Most users will hesitate — or refuse to proceed at all.
That’s where code signing comes in. It ensures that the file is authentic, secure, and hasn’t been tampered with. A digital signature shows users and systems that the code came from a verified source and remains unchanged since publication.
In the digital age, a website is not just a business card but a key tool for business, communication, and sales. However, many site owners forget one important detail — backup.

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, 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.
What Are Security Headers?
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.
Key Types of Security Headers
HTTP Strict Transport Security (HSTS)
Ensures that browsers always use HTTPS to connect to websites, preventing potential attacks that downgrade the protocol to insecure HTTP.
Content Security Policy (CSP)
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.
X-Frame-Options
Determines whether a site can be embedded in frames on other websites, helping to prevent clickjacking attacks.
X-XSS-Protection
Enables built-in browser filters to detect and block XSS attack attempts.
X-Content-Type-Options
Prevents browsers from guessing MIME types, reducing the risk of executing malicious scripts disguised as other file types.
Referrer-Policy
Controls what referrer information is sent when navigating between sites, reducing the risk of confidential data leakage.
Access-Control-Allow-Origin
Specifies which domains can access your web application’s resources, which is crucial for API security.
How Security Headers Prevent Vulnerabilities
Using security headers helps prevent various types of attacks, including:
Protocol Downgrade Attacks: HSTS prevents attempts to downgrade security from HTTPS to HTTP.
After applying these changes, restart your server to activate the new settings.
Conclusion
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.
