Why Manual Security Audits Aren't Enough
Following steps 1 through 9 will reduce your attack surface by over 90%. However, security is not a one-time project. New core vulnerabilities are disclosed daily, and theme scripts you installed months ago might suddenly become active targets.
A WordPress site audit requires active monitoring. Rather than manually comparing file code changes, deploying a lightweight background tool is critical to ensure file signature integrity.
WordPress Hardening Checklist FAQ
Does changing the default database table prefix break my site?
If done manually on a live site, it can cause database mapping errors. It is safest to set up a custom prefix (e.g., `pw_shop_`) during initial installation or use a migration plugin with verified safety records.
How does virtual patching block attacks?
A virtual patch intercepts requests prior to processing by WordPress. If an incoming payload contains a query matching SQL injection or XSS patterns, the request is immediately dropped before it reaches the vulnerable theme or plugin file.
