Sudo Pair

Overview

sudo_pair is a sudo plugin that ensure that no user can act entirely on their own authority within these systems. Once configured if a user tries to get root privileges, he will need an authorization from a pair that will monitor over his session.

Build

cd sudo-pair
charm build

Usage

Add to an existing application using juju-info relation.

Example:

juju deploy ubuntu
juju deploy ./sudo-pair
juju add-unit ubuntu
juju add-relation ubuntu sudo-pair

Configuration

The user can configure the following parameters:

• groups_enforced (default: root): This is a comma-separated list of group names that sudo_pair will gate access to. If a user is sudoing to a user that is a member of one of these groups, they will be required to have a pair approve their session.
• groups_exempted(default: none): This is a comma-separated list of group names whose users will be exempted from the requirements of sudo_pair. Note that this is not the opposite of the groups_enforced flag. Whereas groups_enforced gates access to groups, groups_exempted exempts users sudoing from groups. For instance, this setting can be used to ensure that oncall sysadmins can respond to outages without needing to find a pair.
• bypass_cmds (default: none): This is a comma-separated list of full path commands that have to be bypassed from sudo pairing
• bypass_group (default: none): This is the unix group for which the commands specified through bypass_cmds will be bypassed from sudo pairing approval
• auto_approve (default: true): If true, auto approval is permitted.
