Which of the following actions is recommended after implementing changes to baseline configurations?

Verifying that the required security controls were updated after implementing changes to baseline configurations is a crucial step in maintaining effective security management. This action ensures that any modifications made do not inadvertently weaken the system's security posture. When changes are made, such as updates to software, hardware, or network settings, it's vital to reassess and update security controls to align with those changes.

By confirming that security controls are updated, organizations can ensure compliance with standards and regulations, such as the NERC CIP Framework, which emphasizes the importance of safeguarding critical infrastructure. This verification process helps to identify and mitigate any new risks that may arise from configuration changes, thus preserving the integrity and availability of critical systems.

Moreover, ongoing verification fosters a proactive security culture, enabling teams to continuously monitor and adapt security measures in response to evolving threats. This approach reduces the risk of vulnerabilities going unnoticed, which could lead to potential breaches or system failures.

In contrast, ignoring updates to security controls, delaying action until the next audit, or reverting back to previous configurations could compromise security and result in compliance violations, leaving the system more susceptible to attacks.
