Security
Security
- Sun’s RPC defines three levels of security
- none: the default
- It’s entirely up to the application, based on the parameters it was passed and whatever state is has, to decide whether or not to process the request
- Unix authentication
- Every request has a timestamp, the hostname, the client’s euid, egid, and all group id’s the client belongs to. The server can examine these and decide.
- DES authentication
