What actions are required when a security incident occurs as tracked in eMASS?

By documenting the incident through reporting, it allows organizations to maintain an accurate account of vulnerabilities and corrective actions.

Additionally, updating the POA&Ms and security controls is vital for enhancing the overall security posture of the organization. This process involves assessing whether existing controls were effective or if new controls are necessary to mitigate future risks. It is essential to integrate lessons learned from the incident into the security framework to prevent recurrence and improve response strategies.
