ModSecurity
ModSecurity is an open-source web application firewall (WAF) that provides real-time monitoring, logging, and access control for web applications. It operates as a module for web servers like Apache, Nginx, and IIS to protect against common attacks such as SQL injection, cross-site scripting (XSS), and other vulnerabilities. By analyzing HTTP traffic, it helps secure web applications by filtering malicious requests and enforcing security policies.
Developers should learn and use ModSecurity when building or maintaining web applications that require robust security against cyber threats, especially in environments handling sensitive data like e-commerce or financial services. It is essential for compliance with standards like PCI-DSS and for mitigating OWASP Top 10 risks, making it a critical tool for DevOps and security-focused roles in production deployments.
