Starting with version 1.8.0, sudo supports a modular framework
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@example.com.
Privilege Manager for Sudo
The first available third party plugin is Privilege
Manager for Sudo
, which brings advanced features from the 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. Privilege Manager 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
Manager for Sudo is available in freeware and commercial versions.
is an I/O plugin for sudo that can be used to require that another
party approve commands before they are allowed to run. The running
command's output is mirrored on the approver's screen and the command
can be terminated by the approver at any point.
