DIACAP Team. Comprised of the individuals responsible for implementing the DIACAP for a specific DoD IS.  At a minimum the DIACAP Team includes the DAA, the CA, the DoD IS program manager (PM) or system manager (SM), the DoD IS IA manager (IAM), IA officer (IAO), and a user representative (UR) or their representatives. (DoDI 8510.01, E2.25)

*update: DIACAP is DoD Risk Management Framework (2014)

Designated Accrediting Authority (DAA). The official with the authority to formally assume responsibility for operating a system at an acceptable level of risk. This term is synonymous with designated approving authority and delegated accrediting authority.

(DoDI 8500.2, E2.1.28)

    Here is a good question from someone who stumble upon the site:

    I have the following questions about certain DIACAP team positions:

    DAA – My DAA is a one star, Your telling me he’s supposed to sit in on the meetings?

    PM/SM – This would be the system owner or system POC?

    CA – ??? … how would this differ from the DAA?

    CAR – ??? is this similar to the role of the ACA?

    The DAA usually delegates to a lower more tech savvy person. Or at least, that has been my experience. When I was in the AF, our commander (full bird) was the DAA which was pushed down from the Wing Commander. All packages were read and evaluated by an Ops officer (a Capt). If the Ops officer approved then the commander would usually sign off. These days the DAA has been pushed to an even higher level (in the Air Force anyway). This Capt could be seen as the Certifying Authority, because it should be someone who is knowledgeable enough to realize what risks to take and which ones are unacceptable. They will typically have a lot of say in whether the system is acceptable.

    I don’t know about the other branches, but the USAF depends completely on the IA Component as the CA which is AFCA.

    In the Air Force, the DAA is the AFNETOPS/CC. Stick with DoD 8510.10 and 8500.02.

    more on the IA Components can be found here http://elamb.org/diacap-activity-1-initiate-and-plan-certification-accreditation/

    The IA Component is a great guide for the entire process for the Army its Army NETCOM Information Assurance Office; Navy info can be found here: http://www.doncio.navy.mil

    The PM or Program Management Office is critical because they manage the money and sustainment issues on a system. They will have to answer important sustainment questions as well as help coordinate how certain IA Controls will (or won’t – lol) be implemented. The PM works closely with the system owner (and I suppose it can sometime be the system owner). 8510 points out which roles can be one and the same and which ones can not.

    I am a program manager for a manpower tool that does not receive or transmit data. It reads a file and the output is written to a file (much like Excel, Access operrates. Would that be categorized as a system? The tool is an application installed on an individual’s PC,,,

    I don’t have a lot of experience with plain applications.

    I would contact the AF Infostructure Technology Reference Model (i-TRM) to determine the appropriate action to take https://infostructure.hq.af.mil — I think that is the link. They are who you want to talk to for applications.

    There is a STIG for applications, but I believe its only applies to servers.

    What requirements apply when considering a DIACAP on a server that will host applications that are on the approved software listing? Does the system require a full DIACAP or can it have an executive package created? The system itself is not going to be an application server in the sense that it will be dedicated to hosting one application. Also, what requirements apply when the server will host user shares and organizational data? For file servers already within and enclave (our servers on on a domain we do not own) does the host hold an responsibility for providing our organization with info regarding Inherited IA Controls?

    I would like to know the answer to Cedric's question also.

    Hi Rob, thanks for all of your work. I’ve tuned in to your thoughts since 2009 – did you notice that RMF transformation was listed on the DIACAP KS all the way back in 2010?? I see from your http://diarmfs.com/ site that it looks like things are moving closer…

    If you know of any slides that are written from contractor / vendor view on DIACAP process, can you turn me on to them? I have a good project plan on tasks / planning from the vendor’s view to *integrate* with the Govt IA functions that I can share.

    On my site I have a lot of IA papers and thoughts…take a look when you have some time.

    Rob, I work in IA, and have worked for both the government (IC) and private enterprise on contract to the Government (CIA, DNI, DISA, NGA) since 1971. I’ve been involved in the transition to the RMF from DCID 6/3 and DIACAP practically since its inception (ca 2006) and would like to join your site, but I can’t get by the “register” tag, which takes me to an invalid site name alert. Can you help me out? I have questions for you. Thanks.
