The correct answer is A. Continuous Monitoring Phase.
The Continuous Monitoring Phase is the phase in the Security Assessment and Authorization (SA&A) process where the system security plan update and the Plan of Action and Milestones (POAM) update take place.
Continuous Monitoring is an ongoing process of observing, analyzing, and responding to changes in the information system and its environment. The objective of this phase is to maintain an adequate security posture and to ensure that the security controls continue to be effective in the face of changing threats and vulnerabilities.
As part of the Continuous Monitoring Phase, the System Owner (SO) and the Authorizing Official (AO) are responsible for updating the System Security Plan (SSP) to reflect any changes to the system's security posture. The SSP documents the security controls and safeguards that are in place to protect the system and its data. Updates to the SSP may include changes to the system's security requirements, the security controls implemented, or changes to the system's environment.
The Plan of Action and Milestones (POAM) is a document that identifies and tracks remedial actions that need to be taken to address security weaknesses and deficiencies in the system. The POAM is updated as part of the Continuous Monitoring Phase to reflect changes in the system's security posture and to track the progress of remedial actions.
In summary, the Continuous Monitoring Phase is the phase in which the System Security Plan (SSP) and Plan of Action and Milestones (POAM) are updated to ensure that the system maintains an adequate security posture and to address any changes in the system's security requirements, environment, or vulnerabilities.
