DIACAP requires that the system owner see that a review of the IA posture of their system be conducted at least annually.
DIACAP requires you to review your IA posture at least annually for as long as the system is in operation (or every 6 months if it is a MAC I system).
DIACAP requires you to review your IA posture
Yes - DIACAP requires you to review your IA posture. DoDI 8510.2 (DIACAP) and DoDI 8500.2 both require that the IA posture of all systems belonging to an organization must be reviewed at least once a year. Furthermore, the system must be assessed and undergo reaccreditation by the Principal Accredditation Authority (PAA) - which generally means the DAA - at least every 3 years.
According to DoD 8510.01 (DIACAP), paragraph 5.16.8, the Program Manager (PM) or System Manager (SM) shall:"Ensure annual reviews of assigned ISs required by FISMA are conducted."So reviews must occur at least once a year.
A DIACAP review has to be executed for every new system, for every major change to an existing system, and at least every 3 years for any currently accredited system.
No - DIACAP required that the posture be at least partially reviewed every year (for the Annual Security Review - aka ASR) except for very sensitive systems that must be reviewed more often - usually every six months. A comprehensive review is required every 3 years under DIACAP.
DIACAP replaced DITSCAP as the process for certification and accreditation of DoD information systems. DIACAP supersedes DITSCAP.
DIACAP is DoD Instruction 8510.01. In that respect, SOME DoD instructions fall under DIACAP, but most DoD instructions have nothing to do with DIACAP.
DIACAP requires that the security posture of any DoD system be evaluated at least annually. A system must undergo the full DIACAP process prior to being placed into service, whenever a major change occurs, and prior the expiration of the accreditation of the system if it already has an ATO. The DAA issues an ATO for a system for up to 3 years.
