August FAQ – CDS CAP

Question: How long does the CDS CAP take?
Answer: There are many factors, which affect the length of getting your cross domain request accredited. Things that can cause delays are incomplete or unsatisfactory accreditation documents being submitted, choosing a technology which has not already completed LBSA (Lab Based Security Assessment) or requesting to use a point-to-point technology if an enterprise service could be used instead. If you were going to DISA’s Cross Domain Enterprise Services the timeline would depend on their schedules and capabilities to get your flows implemented or a new system built to meet your needs. If you were utilizing a point-to-point solution, which was on the UCDSMO baseline and already, completed LBSA you could be approved as short as a few months.

As far as our offices timelines go, once we receive a completed and satisfactory package from a CDSE we will review and post the eCDTAB or schedule it for CDTAB within 1-3 business days. E-votes usually last a week. If it passes CDTAB successful it could be e-vote for DSAWG or placed on the next meeting agenda. If e-voted, we will schedule the e-vote closure 1 week from the date of posting. Once the e-vote is closed and any remaining signatures are provided we will also issue a CDSA within 1-3 days. We recommend requesting CDSA’s at least 2 weeks ahead of schedule. This timelines describes normal processing but we also do expediting processing for urgent mission needs. For more information call 301-225-2905.

Question: Is there a document that lists the steps required to submit a request to DISA?
Answer: Yes, Appendix H of the DISA Connection Process Guide lists the steps. It can be viewed by going here.

Question: Can DISA support Secret to SCI CDS solutions?
Answer: We cannot speak to what DISA Cross Domain Enterprise Services can support. However, in regards to the approval process, the IC registration process which is described in the DISN CPG Appendix H. This registration process covers IC guards, which connect to DoD networks.

Question: Is there going to be a single process for DHA to DISA 2.0 or is everything going to need to be submitted individually?
Answer: As of right now the documentation would need to be submitted individually.

Question: Can requirement requests be submitted for risk analysis before ST&E?
Answer: Phase 1 of the CDS process is documenting the requirement and performing an analysis of alternatives. DODI 8540.01 directs DoD mission partners not to purchase or commit to purchasing a solution until phase 1 of the CDS process is completed. Your CDSE, the CDTAB and DSAWG will make recommendations and ultimately tell you what level of risk the community is willing to accept for your requirement. In Phase 2 you will have selected a technology and documented a Site Based Security Assessment (SBSA) (RMF term replacing ST&E) plan.

Question: How do you know who your CDSE is?
Answer: Contact the DSAWG team.

Question: Do you have a link or POC for the process of CDS to JWICS?
Answer: However, in regards to the approval process, the IC registration process which is described in the DISN CPG Appendix H. This registration process covers IC guards, which connect to DoD networks.

Question: Can DSAWG meetings be set up for high-level approvals – not on the usual monthly schedule?
Answer: There has been an occasional DCS session DSAWG to discuss high-level issues. There is also an expedited CDS approval process for critical mission needs. In this case, the DSAWG Chair has the authority to administratively approve an urgent operational need for an interim until the matter can be revisited at a DSAWG meeting.

Question: Do you have a listing for the CDSE POC’s?
Answer: Yes but our CDSE listing is updated on a weekly basis. Please send an email to to request your CDSE POC’s.

Question: Is there a POC lead we can reach out to and discuss a huge effort with 32 different system interfaces that are coming soon?
Answer: We recommend reaching out to your CDSE to discuss way aheads first. They will gather the details we need and set up a phoneocon with our office and yourself to discuss possibly way aheads.

Question: Does DISA maintain/provide a list of approved CDS by domain?
Answer: The Unified Cross Domain Services Management Office is responsible for maintaining a CDS Baseline list. This list does specify what domains the CDS is approved to operate.

Question: Who is the DIA POC for CDS?

Question: What is the purpose of the Mission Partner Training Program? 
Answer: The Mission Partner Training Program was developed by the Risk Adjudication and Connection Division (RE4) SMEs to provide a training and education opportunity to mission partners in all areas associated with Enterprise Connections such as: PPSM, DSAWG, Connection Approval, and CDS. The goal for this program is to provide mission partners the policy and process information they need to reduce processing delays due to inaccurate or incomplete information.

Question: How do the topics relate to the DISN Connection Process Guide (CPG)? 
Answer: Connection Approval CBTs are extensions and supplementary to the DISN CPG. They are designed as a visual, interactive way to learn the detailed information described in the CPG, and will be continually updated with new versions of the CPG so that the information, processes, and instructions are always consistent between the two.


Question: Is there a difference between the CBT version available for download and the play now version? 
Answer: The two versions are available for convenience for our Mission Partners. We understand that some connections may not give the ability to stream the training from the website, so it might be more convenient to let the training download first and then watch. The downloadable version is also something Mission Partners can refer to at a later time. The play now version also has closed captioning enabled for accessibility if it would be more convenient to read the text instead of listening to the voice over.

Question: How are topics picked to be developed into CBTs?
Answer: The topics are picked from a variety of sources. Surveys to the Connection Approval, DSAWG, and PPSM analysts helped the training team determine which questions they received most from mission partners, and in-depth metrics analysis on the top connection approval package rejection reasons continues to contribute. Now that the program is growing, interaction from Mission Partners via email and during the Q&A sessions add to training topics. This program is designed to bring information to Mission Partners that is useful and needed, so the syllabus will always remain flexible based on the needs of Mission Partners. Have a suggestion for a training topic? Submit it here.


Question: Who hosts the Q&A sessions? 
Answer: A representative from the Mission Partner Training Program will host and facilitate the sessions and there will be subject matter experts from the different branches in the Risk Adjudication and Connection Division on the line to answer any specific questions you may have.

Question: How do I prepare for a Q&A session? 
Answer: We encourage everyone to watch the computer-based training on the topic that will be discussed in the Q&A prior to the session.

Question: How do I attend a Q&A session? 
Answer: The Q&A sessions are hosted via Defense Collaboration System (DCS), as well as a teleconference bridge. All audio will occur on the bridge. The DCS will have supplementary documentation, a chat for submitting additional questions, and website links to help us improve the sessions for Mission Partners. Please join both the DCS and teleconference for the best Q&A experience.

Question: What time zone are the times in the Q&A schedule and invitations?
Answer: All Q&A sessions times are EASTERN time (EST/EDT).
