What is a recommended action to fix security misconfiguration?

• A. Keep your OS up to date.
• B. Define access rights.
• C. Configure all security mechanisms.
• D. Strongly validate user input.

Answer: (C)

Security misconfiguration is addressed by applying proper, comprehensive configuration across every security control in the environment. When you configure all security mechanisms, you set secure defaults, enable appropriate authentication and authorization, turn on necessary encryption, tighten network and service permissions, and establish proper logging, monitoring, and patch management. This holistic hardening closes gaps that often appear when only one area is addressed—like leaving default credentials or verbose error messages, or keeping unnecessary services enabled. While keeping the operating system up to date, defining access rights, and validating user input are important security practices, they tackle specific issues rather than fixing misconfiguration across the entire stack. Configuring all security mechanisms ensures a consistent, secure baseline and reduces the risk introduced by misconfigurations.
