DRAFT CCSDS RECOMMENDED STANDARD FOR CCSDS BUNDLE PROTOCOL SPECIFICATIONE1.3 AUDITING OF RESOURCE USAGENo mechanisms are defined in this specification to audit or assist with the auditing ofresource usage by the protocol.E1.4 POTENTIAL THREATS AND ATTACK SCENARIOSNo potential threat or attacks scenarios are discussed.E1.5 CONSEQUENCES OF NOT APPLYING SECURITY TO THETECHNOLOGYBy not applying the native security of the BP protocol and the extended security of BSPallowed by BP, the system must rely on security measures provided at the CLA interfaces.For space applications these may be non-existent or merely physical because of the lack ofintegration between payload and ground systems interfaces. If no security is applied at theBP or lower layers, then applications may be open to man-in-the middle attacks, replayattacks, or a general loss of integrity of transported bundles.E2SANA CONSIDERATIONSThe recommendations of this document request SANA to create the following registriesbased on the recommendation of 3.5:a) The registry named Bundle Protocol Compressed Bundle Header Encoding NodeNumbers which consists of a table of parameters:1) the initial registry values are not defined;2) the registration rule for new values of this registry requires no engineeringreview, but the request must come from the official representative of a spaceagency, member of the CCSDS;b) the registry named Bundle Protocol Compressed Bundle Header Encoding ServiceNumbers which consists of a table of parameters:1) limited initial registry values are defined;2) the registration rule for new values of this registry requires an officialrepresentative of a space agency member of the CCSDS request followed byexpert CESG review,E3PATENT CONSIDERATIONSThere are no known patents covering the Bundle Protocol as described in this document andits normative references.CCSDS 734.2-R-1 Page E-2 February 2012
