How frequently should the baseline configuration be monitored for changes?

The baseline configuration must be monitored for changes at least every 35 calendar days as per the NERC CIP v7 standards. This requirement is critical because it ensures that any unauthorized or unintentional changes to the baseline configuration are detected in a timely manner, which can help in maintaining the integrity and security of critical infrastructure systems. Regular monitoring allows organizations to identify deviations from the established configuration, thereby aiding in the prevention of vulnerabilities that could be exploited by malicious actors or inadvertently caused by operational activities. This timeframe strikes a balance between ensuring adequate oversight while not being so frequent that it becomes burdensome to manage effectively.
