Network Information Services (NIS and NIS+) Guide
NIS+ Security Overview
NIS+ protects the structure of the namespace, and the
information it stores, by the complementary processes of authorization and
authentication.
- Authorization
- Every component in the namespace specifies the type of operation it
will accept and from whom.
- Authentication
- NIS+ attempts to authenticate every request for access to
the namespace. Requests come from NIS+ principals. A NIS+ principal
can be a process, machine, root, or a user. Valid NIS+ principals
possess a NIS+ credential. NIS+ authenticates the
originator of the request (principal) by checking the principal's credential.
If the principal possesses an authentic (valid) credential, and if the
principal's request is one that the principal is authorized to perform, NIS+
carries out the request. If either the credential is missing or not valid,
or the request is not one the principal is authorized to perform, NIS+
denies the request for access.
The entire NIS+ security system is described in NIS Security in AIX 5L Version 5.2 Security Guide.
