H Balazs, > BALAZS2: This drafts does not want to define a file format. It intends to use the “generic” file format defined in draft-ietf-netmod-yang-instance-file-format. IMHO the whole aim of draft-ietf-netmod-yang-instance-file-format is to avoid individual drafts defining file formats. Okay. I see it in Section 3 now. > On the below: > > > I suspect that you will need to do a security analysis per YANG object. This has been done the other YANG push family. > BALAZS: The full module is readOnly and not sensitive or private in any manner. The security text for the readOnly parts of YangPush is the exact same text: not very informative, but gives you the illusion of security awareness. > > I suspect that manipulating the reporting intervals could have some security implications. E.g., a hacker could push up the damping period or periodic interval to a level where the information they are changing then becomes invisible to a monitoring system. > BALAZS: The full YAM is read-only so manipulating the data is not a concern. > > > The draft should say something like: > > 1. All protocol-accessible are read-only and cannot be modified. The nature of the read-only data is not deemed to be sensitive in a way necessitating access-control restrictions (e.g., NACM) beyond the client being authenticated. > BALAZS2: OK, Updated with first part, but Rob has asked for an extra sentence about the dangers of revealing read-only data, I added that too. > “All protocol-accessible data are read-only and cannot be modified. > The data in this module is not security sensitive. > Access control may be configured, to avoid exposing > the read-only data.” Okay. s/protocol-accessible data/protocol-accessible data nodes/ > 2. When a file format, the protection afforded by a mutually authenticated transport protocol. Protection of the data must be performed manually, so as to ensure that the data is neither seen nor modified in transit. > Reword as needed. > BALAZS2: Agreed. This is part of normal file handling, transport. So I reworded this to: > “When that data is in file format, data should be protected against > modification or unauthorized access using normal file handling and > secure and mutually authenticated file transport mechanisms.” Okay. The end can be shortened, i.e., just "file handling mechanisms". Kent // contributor
