Organizations today are under increasing pressure to secure dynamic digital ecosystems while keeping pace with accelerated development cycles. To address these challenges, security teams often rely on two key testing methods: dynamic application security testing (DAST) and vulnerability assessment and penetration testing (VAPT). Although both…

Understanding Injection Attacks in Application Security: Types, Tools, and Examples
How Injection Attacks Exploit Web Application Vulnerabilities Injection attacks occur when malicious input is inserted into a web application, exploiting vulnerabilities in unvalidated user input to execute unintended commands. Attackers craft payloads that manipulate how the application processes data, often leading to unauthorized access, data…
Strengthen Your Web Applications with HTTP Security Headers
What is a HTTP security header? An HTTP security header is a response header that helps protect web applications by providing browsers with specific instructions on how to handle website content securely. These headers play a crucial role in mitigating various cyber threats, such as…
Disabling Directory Listing on Your Web Server – And Why It Matters
By default, some web servers allow directory listing, which means that if no default index file (such as index.html or index.php) is present, the server will display a list of all files and directories in that folder. This can expose sensitive files, scripts, and configurations,…
XSS Filter Evasion: How Attackers Bypass XSS Filters – And Why Filtering Alone Isn’t Enough
XSS filter evasion techniques allow attackers to bypass cross-site scripting (XSS) protections designed to block malicious scripts. This article explores some of the most common filter bypass strategies, explains why relying solely on filtering is ineffective, and outlines the best practices for preventing XSS attacks….
Preventing CSRF Attacks with Anti-CSRF Tokens: Best Practices and Implementation
The most widely used method to prevent cross-site request forgery (CSRF) attacks is the implementation of anti-CSRF tokens. These are unique values generated by a web application and validated with each request to ensure authenticity. CSRF attacks exploit a user’s active session to execute unauthorized…
