What is one of the types of events that must be logged for Cyber Security Incidents?

Detected successful login attempts must be logged as a critical aspect of monitoring for Cyber Security Incidents. This is essential for several reasons. First, successful login attempts can indicate authorized access, but they can also be indicative of unauthorized access attempts or potential security breaches. By logging these events, organizations can analyze user behavior, detect anomalies in access patterns, and respond quickly to any suspicious activities.

The logging of successful logins allows for the creation of an audit trail, making it easier to investigate incidents if they occur. It helps in establishing accountability for actions taken within the system and is important for compliance with various regulatory requirements, including those outlined in the NERC CIP standards. Properly maintaining this log also aids in the forensic investigation of security incidents, thereby enhancing the overall security posture of the organization.

Other types of events, such as detected software installations or routine system checks, while important for overall system health and security, do not have the same direct relevance to monitoring access and potential breaches as successful login attempts do. User feedback, while valuable for improving user experience, is typically not associated with the technical monitoring of security incidents.
