Why It Matters

Database and cache ports should never be exposed to the public internet; they are vulnerable to brute force and zero-authentication exploits.

How We Check This

We check whether common administrative and database ports are actively accepting connections on target host IPs.

How to Fix & Implement

Copy-paste configuration blocks tailored for your web server or edge proxy.
