Understanding XSS Protection Across an Entire Domain Cross-Site Scripting (XSS) is one of the most common web vulnerabilities that can impact user security and trust. But with a layered security approach, it’s possible to make XSS nearly impossible to exploit. Here’s how modern web applications protect themselves at every step: ➡️ Input Sanitization – filtering dangerous inputs before they reach the server. ➡️ Output Encoding – ensuring injected code is displayed as text, not executed. ➡️ Content-Security-Policy (CSP) – restricting script execution to trusted sources only. ➡️ File Upload Protection – sanitizing or converting uploaded files to safe formats. ✅ When these defenses are applied at the domain-wide level, every page and endpoint is secured by default. 📌 Takeaway: XSS protection is not just one control—it’s a combination of multiple layers working together to safeguard users and data. #CyberSecurity #XSS #WebSecurity #AppSec #CSP #Infosec

The OWASP Top 10 is the industry gold standard for identifying and mitigating the most critical web application vulnerabilities. Every developer, tester, and security professional should be aware of them. 📌 2025 OWASP Top 10 includes: 1️⃣ Broken Access Control 2️⃣ Cryptographic Failures 3️⃣ Injection 4️⃣ Insecure Design 5️⃣ Security Misconfiguration 6️⃣ Vulnerable & Outdated Components 7️⃣ Identification & Authentication Failures 8️⃣ Software & Data Integrity Failures 9️⃣ Security Logging & Monitoring Failures 🔟 Server-Side Request Forgery (SSRF) ✅ Why it matters: Following these guidelines reduces the risk of breaches, protects customer data, and strengthens your application security posture. #cybersecurity #owasp #websecurity #applicationsecurity #securecoding #infosec #pentesting #ethicalhacking #secure7 #incyberx

Excellent point 👏 penetration testing shouldn’t stop at Layer 7. Focusing only on web apps or APIs while ignoring the underlying infrastructure is like locking the front door but leaving the windows wide open. A complete security assessment should cover: Layer 2/3/4 misconfigurations and exposure Segmentation & access controls inside the network Credential hygiene & privilege misuse Application layer risks (OWASP Top 10 and beyond) Attackers don’t limit themselves to one layer neither should we when testing. This post is a great reminder that true security = defense in depth 👏

Penetration Testing != Just Layer 7 In many organizations, penetration testing only starts after a new VM is provisioned or a new application is installed. And guess what? Most of the time, the focus is solely on Layer 7 … the application layer. Web login? API fuzzing? OWASP Top 10? You’re “secure” now, right? But let me ask: Who tested Layer 3/4 (network exposure, firewall rules, open ports)? Who verified Layer 2 risks (ARP spoofing, MAC flooding)? Who checked if the VM is part of a flat network with RDP wide open internally? In reality, that shiny new app might be sitting on: • A misconfigured server • In a flat VLAN • Exposed via default ports • Sharing the same credentials as 20 other VMs And yet, the checkbox says “Pentest Completed” because Layer 7 looks good. If your pentest stops at the application layer, you’re not testing your security … you’re testing your UI. Security should be layered … just like attacks are. Don’t just test what the user sees. Test what the attacker sees. #CyberSecurity #PenetrationTesting #Infosec #RedTeam #OSIModel #NetworkSecurity #VulnerabilityManagement #VMProvisioning #ITinfrastructure #EDR #XDR #Firewall #ITSecurity

I recently conducted a security assessment on the HTB-Writeup machine, which demonstrated a critical chain of vulnerabilities leading to a full system compromise. The attack path was as follows: 1. Initial Access: Exploited a SQL injection vulnerability in a web-facing CMS Made Simple instance to extract and crack user credentials. 2. Privilege Escalation: Gained root access through a PATH hijacking attack. This was possible because the compromised user was part of a group with write permissions to a directory in the system's PATH variable. This engagement is a clear example of how a combination of poor web application security and insecure system configurations can lead to a critical breach. It highlights the importance of input validation, enforcing the principle of least privilege, and regular security audits. #cybersecurity #pentesting #vulnerability #sqlinjection #pathhijacking #infosec

🚀 Lab: Manipulating WebSocket Messages to Exploit Vulnerabilities Just completed a hands-on lab focused on WebSocket security 🛡 fromPortSwigger. This exercise demonstrated how attackers can intercept and manipulate WebSocket messages to exploit vulnerabilities within a web application. 🔎 Key Takeaways: WebSockets provide real-time communication but can become a weak point if not properly secured. Manipulating requests can lead to privilege escalation, data leaks, or even account takeover. Strong server-side validation is critical - never trust client-side data. Security testing tools like Burp Suite are invaluable in analyzing and tampering with WebSocket traffic. 💡 Lesson learned: Even modern communication protocols like WebSockets are only as secure as their implementation. Continuous testing, validation, and awareness are essential. #CyberSecurity #WebSockets #ApplicationSecurity #BurpSuite #LearningByDoing #TryHackMe #PortSwigger
