CompTIA Exam PT0-002 Topic 5 Question 75 Discussion

* System hardening involves securing a system by reducing its surface of vulnerability, which includes changing default credentials, disabling unnecessary services, and applying security patches.

* Details:

A . Password encryption: Secures passwords but does not address the issue of default credentials.

B . System hardening: Comprehensive approach to securing the system, including changing default credentials.

C . Multifactor authentication: Adds an additional layer of security but does not solve the problem of default credentials being enabled.

D . Patch management: Ensures software is up-to-date but does not directly address default credentials.

* Reference: System hardening is a fundamental practice in securing systems and preventing unauthorized access, as detailed in security best practices and guidelines.
