CompTIA CySA+ CS0-003 Practice Question

Changing the default settings to a secure configuration should be the immediate action taken because it eliminates unnecessary information leakage that may assist an attacker in exploiting the server. Removing the verbose error messages and sample applications reduces the risk of a security misconfiguration leading to potential attack vectors. Disabling unused services also helps reduce the attack surface. Reading documentation and scheduling future security reviews, although important, are not immediate actions for mitigating the discovered vulnerability.
