What it is
The agreement behind AJP-6
STANAG 2525 commits NATO nations to implement AJP-6, Edition B, the Allied joint doctrine for communication and information systems. The agreement itself is short, a letter of promulgation and a single further page, and holds no doctrine of its own: it states an aim, names the publication, and sets out how a nation ratifies and implements it. Its aim is given as an interoperability requirement, "to provide guidance and direction for integrating communication and information systems into the planning, conduct and assessment of Alliance operations".
A STANAG is the instrument, not the content. Nations ratify it, implement it through their own regulations, manuals and training, and a company encounters it only because a contract or a tender invokes the doctrine. Ratification and implementation are separate steps, a nation may ratify with reservations, and so the question "is STANAG 2525 mandatory" has a contractual answer and no general one.
What implementation means here
The agreement is "effective upon receipt for use by the participating nations and NATO bodies", and nations are invited to examine their ratification and advise NATO's Standardization Office of their intention. National responses are recorded in the NATO Standardization Document Database.
Implementation is defined on its own terms: the agreement "is implemented when the procedures detailed have been incorporated in national regulations, manuals and training." Allies and NATO bodies then provide implementation details through NATO's electronic reporting tool, and partner nations are invited, rather than required, to do the same.
Where it sits among the other agreements
STANAG 2525 is not read alone. It names six sibling agreements covering the rest of NATO's Allied Joint Doctrine architecture: STANAG 2437 for AJP-01, the capstone doctrine; STANAG 2190 for AJP-2 on intelligence, counter-intelligence and security; STANAG 2490 for AJP-3 on the conduct of operations; STANAG 2182 for AJP-4 on logistics; STANAG 2526 for AJP-5 on the planning of operations; and STANAG 6539 for AJP-10 on strategic communications. Two NATO policy documents are listed as related and are not in our catalogue: MC 0422/6, NATO policy for information operations; and MC 0628, NATO military policy on strategic communications.
What it does not do
It describes no certification, no notified body, no government quality assurance and no audit of any organisation. The only check it names is of itself: a review in accordance with AAP-03, recorded in the NSDD. It sets no NATO effective date, recording "Not applicable". This is military communications and information systems doctrine, not an information security standard: nothing here maps onto ISO 27001, NIST or any other organisational control set, and reading it that way would misread what the agreement covers.
Edition and lineage
This is Edition 3, promulgated 5 April 2024. It supersedes "STANAG 2525, Edition 2, dated 28 February 2017".
