A practical guide to secure and harden Apache HTTP Server. The Web Server is a crucial part of web-based applications. Apache Web Server is often placed at the edge of the network hence it becomes one of the most vulnerable services to attack. Having default configuration supply much sensitive information which may help hacker to prepare for an attack the applications. The majority of web application attacks are through XSS, Info Leakage, Session Management and SQL Injection attacks which are due to weak programming code and failure to sanitize web application infrastructure. Interesting research by Positive Technologies reveals, 52% of the scanned application had high vulnerabilities. In this article, I will talk about some of the best practices to secure Apache HT...
