With over 30% market share across all public-facing websites, Apache servers are hugely popular, as well as a major target. Recent incidents involving Apache vulnerabilities resulted in massive payment card breaches, encrypted data theft, and rampant illicit crypto-mining. Given the frequency and scale of such attacks, adequately safeguarding Apache deployments must be a priority.
This comprehensive guide outlines expert-validated best practices to harden servers against real-world threats. By implementing these top 10 security controls, you can significantly improve resilience against compromise. Statistics clearly demonstrate the value at stake:
- Over 250 million websites run on Apache, including major brands like PayPal, Pinterest, Bloomberg and more
- The 2022 Apache Log4J vulnerabilities received a perfect 10.0 score on the CVSS risk rating scale
- Attackers leveraged these Apache flaws to infiltrate thousands of corporations globally
- A single vulnerable server provides criminals access to breach entire company networks and clouds
So whether managing business-critical e-commerce sites or internal-use applications, proactively applying security measures is essential. As an experienced CISO and former security researcher, I have helped major enterprises address Apache exposures for over a decade. This article consolidates key learnings into an actionable checklist for security administrators and IT teams. I also cite supporting data plus expert guidance throughout.
