Sudo Shell is a wrapper to run a login shell with sudo
for the purpose of session audit logging.

Introduction
The sudo
command provides built-in session logging.
Combined with sudoreplay
it provides an easy way to review session logs on a
bastion host.
When used as a system login shell, it will force session logging.
Another common pattern
is to use the OpenSSH ForceCommand
directive in sshd_config
combined with the script
command to log sessions.
This is ineffective because the user can easily bypass it.
Using sudosh
provides a more secure alternative that cannot be bypassed since it does not depend on ForceCommand
.
Usage
Here's how to use it in 3 easy steps. Checkout the precompiled releases if you don't want to build it yourself...:
- Enable
sudo
logging. Edit/etc/sudoers.d/sudosh
:
Defaults log_output
Defaults!/usr/bin/sudoreplay !log_output
Defaults!/sbin/reboot !log_output
- Add this command to
/etc/shells
:
/usr/bin/sudosh
Tip: to prevent users from using other shells to login, remove those shells from /etc/shells
.
- Update the user
foobar
to use thesudosh
shell.
chsh -s /usr/bin/sudosh foobar
echo 'foobar ALL=(foobar) ALL' > /etc/sudoers.d/sudosh-foobar
NOTE: filenames in sudoers.d
cannot contain the .
character
