What constitutes a baseline in the context of eMASS?

In the context of eMASS, a baseline is defined as a set of minimum security controls required for a specific category of information system. This framework serves as a foundational standard against which the security posture of an information system can be measured and assessed. By establishing these minimum controls, organizations ensure that their systems maintain a certain level of security and compliance with applicable regulations and standards.

Baselines play a crucial role in risk management and cybersecurity frameworks, as they provide a structured approach to identifying and implementing necessary security measures. They help organizations to standardize security practices, allowing for more efficient assessment and remediation of vulnerabilities.

In this context, the other options do not align with the definition of a baseline in eMASS. A proposed budget for system enhancements addresses financial planning rather than security standards. A list of potential users pertains to user access and permissions, while a summary of security incidents focuses on past security events rather than establishing future security requirements. Thus, the correct choice underscores the importance of minimum security controls in maintaining robust information system security management.
