Final answer:
The tendency for B. security controls to potentially degrade in effectiveness over time reinforces the need for continuous risk assessments and monitoring programs.
Step-by-step explanation:
The subject of this question is Security Controls. Security controls refer to the measures taken to protect the confidentiality, integrity, and availability of information systems. These controls include administrative controls, technical controls, and physical controls.
In this context, the tendency for security controls to potentially degrade in effectiveness over time reinforces the need to maintain risk assessments during the entire system development life cycle and also the importance of continuous monitoring programs to obtain ongoing situational awareness of the organizational security posture.
For example, if a firewall is not regularly updated and patched, it may become less effective in blocking malicious traffic. Similarly, if access control policies are not reviewed and updated, they may become outdated and inadequate.
