What is the requirement for information systems under the DoD cybersecurity framework?

• A. They must undergo annual reviews only
• B. They must meet the applicable security controls and undergo periodic assessments
• C. They only need to comply with international standards
• D. They must be overhauled every five years

Answer: (B)

The requirement for information systems under the DoD cybersecurity framework emphasizes that these systems must meet specific security controls and undergo periodic assessments to ensure that they remain secure and resilient against threats. This is in line with the overarching goal of maintaining a robust cybersecurity posture, which involves continuous monitoring and reassessment of security measures to address any vulnerabilities or changes in the threat landscape. By adhering to applicable security controls, information systems can manage risks more effectively, ensuring they comply with established policies and regulations. Periodic assessments serve to evaluate the effectiveness of those security controls, providing necessary updates and adjustments based on emerging threats or advancements in technology. This approach aligns with a risk management framework, emphasizing ongoing vigilance rather than static compliance. The other options do not capture the holistic and proactive nature of the DoD's cybersecurity requirements. For example, undergoing annual reviews only would imply a limited frequency of evaluation that may not be sufficient given the rapidly evolving cybersecurity threats. Compliance with international standards alone does not address the specific needs or requirements defined by the DoD framework. An overhaul every five years could lead to significant gaps in security posture if more immediate actions are not taken to respond to ongoing threats. Therefore, the focus on meeting security controls and conducting periodic assessments is key to ensuring the resilience and security
