Starting with version 1.8.0, sudo supports a modular framework
that supports third-party policy and I/O logging plugins. In this framework, when a user runs sudo
, the front-end queries a policy plugin to determine whether or not the command is to be allowed. If it is allowed, the policy plugin returns a description of how to run the command along with the argument vector and environment to pass to the execve()
system call. While the command is being run, the I/O plugin, if any, is passed all input to and output from the command.
This makes it possible for third parties to extend sudo without replacing it. Extending sudo, rather than replacing it outright, has the advantage of allowing users to maintain their existing work flow while providing extra features that enterprise users want.
Below is a list of known third-party sudo plugins. If you have developed a plugin and would like to be added to this list, please send mail to [email protected].
Quest One Privilege Manager for Sudo
The first available third party plugin is Quest One Privilege Manager for Sudo, which brings advanced features from the Quest One Privilege Manager for Unix product to sudo. These features include a central policy server, centralized management of sudo and the sudoers policy file, centralized reporting on sudoers access rights and activities, as well as keystroke logging of activities performed through sudo. Quest One makes administering sudo across the entire enterprise easy, intuitive and consistent--eliminating the box-by-box management of sudo that is the source of so much inefficiency and inconsistency.
Quest One Privilege Manager for Sudo is available in freeware and commercial versions.
