Web Application Firewalls (WAF)

Imagine a powerful shield standing between your web applications and the dangers of the digital world.

That’s precisely what a web application firewall (WAF) does.

A web application firewall is a specialized security solution designed to protect web applications from various cyber threats.

It acts as a protective shield, monitoring and filtering incoming traffic between a web application and the internet to identify and block malicious requests and thwart potential attacks.

While both WAFs and traditional firewalls provide security, they serve different purposes and operate at different levels.

Traditional firewalls focus on securing your network by monitoring and filtering traffic between internal and external networks based on predefined rules. 

WAFs, on the other hand, specifically target the application layer and protect web applications from targeted attacks and application-layer vulnerabilities.

Traditional firewalls act as the first line of defense, monitoring network traffic and blocking unauthorized access based on predefined security rules. 

On the other hand, WAFs dive deeper, focusing specifically on safeguarding web applications from targeted attacks that can slip past traditional firewalls.

Common Vulnerabilities WAFs Defend Against

WAFs are designed to protect web applications from a range of common vulnerabilities, including:

1. SQL Injection: A technique where cybercriminals inject malicious SQL code into a web application’s input fields, potentially gaining unauthorized access to sensitive data or manipulating the application’s functionality.

2. Cross-Site Scripting (XSS): An attack where malicious scripts are injected into a trusted website, potentially allowing an attacker to steal user data, hijack user sessions, or deface the website.

3. Distributed Denial of Service (DDoS): An attack where multiple systems overwhelm a web application’s server with traffic, causing it to become unavailable or unresponsive to legitimate users.

4. Cross-Site Request Forgery (CSRF): An attack that tricks users into performing unintended actions on a web application while they’re authenticated, potentially leading to unauthorized data manipulation or account compromise.

5. Remote File Inclusion (RFI): An attack where an attacker uploads and executes a malicious file on the server, potentially leading to unauthorized access, data theft, or further attacks on the server.
