CISSP-ISSEP: Information Systems Security Engineering Professional

FITSAF Level 4 represents the stage at which implemented procedures and controls are tested and reviewed. Level 5 is the subsequent stage, in which those procedures and controls are fully integrated into a comprehensive security program.

An Intrusion Detection System (IDS) monitors and analyzes computer or network activity to detect security incidents, suspicious behavior, and potential breaches.

Registration Task 2 registers the system by informing the DAA, Certifier, and User Representative that the system will require certification and accreditation (C&A) support.

NIST SP 800-37 identifies Task 4 as the Security Control Assessment task, including the subtask for documentation and supporting materials required to assess information-system security controls.

A stateful packet-filter firewall keeps connection-state information, allowing it to determine whether a packet belongs to an established or valid session and apply filtering decisions in that context. Cisco describes stateful inspection as monitoring the state of network connections, unlike simple packet filtering that does not validate packet sequence or connection context.
