Learn what software vulnerabilities are, how they are discovered, and why patching is essential for website security.
What is Cross-Site Scripting (XSS)?
Understand XSS vulnerabilities, how attackers inject malicious scripts into web pages, and how to prevent them.
What is SQL Injection (SQLi)?
Learn how SQL injection attacks work, how they exploit database queries, and how WAFs and parameterized queries prevent them.
What is Directory Traversal?

DDoS & Attack Explainers
DDoS Attacks Explained
Comprehensive guide to Distributed Denial of Service attacks, how they work, and how CDN and WAF services mitigate them.
DNS Amplification Attacks
Learn how Layer 3 DNS amplification attacks use open resolvers to flood targets with massive traffic volumes.
HTTP Flood Attacks
Understand Layer 7 HTTP flood attacks that overwhelm web servers with legitimate-looking requests.
Volumetric DDoS Attacks
Learn how volumetric attacks saturate network bandwidth and how Anycast-based CDNs absorb them at the edge.
Protocol DDoS Attacks
Understand protocol-layer attacks like SYN floods and how they exploit weaknesses in network protocols.
Brute Force Attacks

Web Malware
SEO Spam
Learn how attackers inject spam links and pages into compromised websites to hijack search engine rankings.
Website Malware
Understand common types of website malware, how sites get infected, and what steps to take for cleanup and prevention.
Phishing Attacks via Websites
Learn how attackers use compromised websites to host phishing pages that steal credentials and financial data.
Credit Card Skimmers
Understand how JavaScript-based credit card skimmers steal payment data from e-commerce checkout pages.
Website Blacklists
Learn what website blacklists are, how your site can end up on one, and steps to get delisted.
Email Security
What is SPF?
Learn how Sender Policy Framework works to prevent email spoofing by specifying which mail servers can send for your domain.
What is DKIM?
Understand DomainKeys Identified Mail, how it uses cryptographic signatures to authenticate email messages.
What is DMARC?
Learn how DMARC ties together SPF and DKIM to give domain owners control over email authentication and reporting.
Security Headers
What are Security Headers?
Learn about HTTP security headers that protect your website from XSS, clickjacking, MIME sniffing, and other attacks.
How to Configure Security Headers
Step-by-step guide to implementing security headers on Apache, Nginx, and through your CDN or WAF.
HSTS (Strict Transport Security)
Understand how HSTS forces browsers to use HTTPS, preventing protocol downgrade attacks and cookie hijacking.
Content Security Policy (CSP)
Learn how CSP headers prevent XSS and data injection attacks by controlling which resources browsers can load.
What is a MIME Type?
Understand MIME types, how they control content handling in browsers, and why X-Content-Type-Options matters.
