IT Observer - Security in Plan 9 Operating System

Security in Plan 9 Operating System

The security architecture of the Plan 9" operating system has recently been redesigned to address some technical shortcomings. This redesign provided an opportunity also to make the system more convenient to use securely. Plan 9 has thus improved in two ways not usually seen together: it has become more secure and easier to use.

The central component of the new architecture is a per-user selfcontained agent called factotum. Factotum securely holds a copy of the user's keys and negotiates authentication protocols, on behalf of the user, with secure services around the network.
