A Certified Ethical Hacker (CEH) is auditing a company’s web server that employs virtual hosting.

CEH guidance for web server hardening prioritizes controls that reduce exploitable conditions across the broadest set of threats. While obscuring paths (for example, unusual directory names like “certrcx” or storing content under “/admin/web”) may slightly slow down casual discovery, CEH emphasizes that security through obscurity is not a reliable control. If an attacker can identify the server root, document root, and virtual directory structure (through misconfigurations, directory listing, error leakage, backup exposure, or known-path enumeration), then the real risk becomes unpatched vulnerabilities in the web server, modules, libraries, and underlying OS.

Regularly updating and patching the server software is the most direct, high-impact countermeasure because it closes known vulnerabilities attackers routinely exploit (RCE, privilege escalation, auth bypass, path traversal, request smuggling, etc.). CEH materials also stress that virtual hosting expands the attack surface (multiple sites, shared services, shared misconfigurations), making systematic patching and configuration management even more important.

Option A (moving the document root to a different disk) may help with organization and, in some cases, recovery planning, but it does not inherently reduce vulnerabilities. Option C (changing IPs) is not a security control; it may complicate blocking lists but doesn’t fix the underlying weakness. Option D (using LAMP) is an architectural choice, not a security measure by itself—an open-source stack can still be insecure if misconfigured or unpatched.

Therefore, CEH-aligned best practice is regular patching and updates.
