Learn how to secure Microsoft IIS with practical hardening best practices, attacker-focused insights, and continuous validation strategies. This guide covers common IIS misconfigurations, real-world exploitation techniques, and how to protect web applications running on IIS servers.
SNI proxy SSRF vulnerabilities: Misconfigurations, exploitation, and defense
SNI proxy SSRF is a lesser-known but high-impact vulnerability class where misconfigured proxies route traffic based on attacker-controlled TLS metadata. Under specific conditions, this can expose internal services and even cloud metadata endpoints in AWS and Azure. This article explains how these attacks work, when they are exploitable, and how to defend against them.
What is an IDOR vulnerability?
Insecure direct object references (IDOR) are a type of access control vulnerability where an application exposes internal object identifiers – such as user IDs, order numbers, or file names – without verifying whether the requesting user is authorized to access them. IDOR is no longer…
Your session cookies are probably misconfigured: How to fix cookie security flags

REST API security testing: A complete guide
Learn how to perform REST API security testing with a practical, step-by-step approach. This guide covers the OWASP API Security Top 10, common vulnerabilities, and proven techniques to discover, test, and validate real API risks using modern automated tools.
Configuring your web server to not disclose its identity
If you are running a web server, it often shows the world what type of server it is, its version number, and sometimes even the operating system. This information is exposed in HTTP response headers and can be obtained with a simple request using a…
OWASP Top 10: Why software and data integrity failures are a real-world risk
Software and data integrity failures—ranked A08 in the OWASP Top 10—are no longer edge cases. They’re an escalating threat across modern web ecosystems, as attackers increasingly target the gray areas between secure code and secure deployment. For security teams, the challenge is validating trust in…
How to prevent SQL injection in C#
SQL injection is still a serious threat in modern web apps. This guide shows how C# developers can prevent injection with secure coding practices combined with a DAST-first security approach that proves vulnerabilities before attackers can exploit them.
Cryptographic Failures: An OWASP Top 10 Threat
What is cryptography? To understand cryptographic failures, it is important to first understand cryptography. Cryptography is a method of securing communication so only authorized parties can access the information. It involves converting readable data (plaintext) into an unreadable format (ciphertext) using encryption algorithms. Only those…
