NAME
       ninja   Privilege escalation detection system for GNU/Linux

SYNOPSIS
       ninja filename

DESCRIPTION
       Ninja  is  a privilege escalation detection and prevention system for GNU/Linux hosts. While running, it will monitor process activity on the local host, and
       keep track of all processes running as root.  If a process is spawned with UID or GID zero (root), ninja will log necessary information about  this  process,
       and optionally kill the process if it was spawned by an unauthorized user.

       A "magic" group can be specified, allowing members of this group to run any setuid/setgid root executable.

       Individual executables can be whitelisted.  Ninja uses a fine grained whitelist that lets you whitelist executables on a group and/or user basis. This can be
       used to allow specific groups or individual users access to setuid/setgid root programs, such as su(1) and passwd(1).


CONFIGURATION
       Ninja requires a configuration file  to  run.  For  more  information  about  the  configuration,  please  refer  to  the  "default.conf"  file,  located  at
       "/usr/share/doc/ninja/examples/" in the source tree.  There, all the available options are explained in detail.


WHITELIST
       The  whitelist  is  a plain text file, containing new line separated entries.  Entries consists of three fields, separated by colons.  The first field is the
       full path to the executable you wish to whitelist.  The second field is a comma separated list of groups that should be granted  access  to  the  executable.
       The third field is a comma separated list of users.

       <executable>:<groups>:<users>

       The second or third field can be left empty.  Please refer to the example whitlist located in "/usr/share/doc/ninja/examples/".

       Remember that it is a good idea to whitelist programs such as passwd(1) and other regular setuid applications that users require access to.


SECURITY
       The  goal  of  this  application is to be able to detect and stop local, and possibly also remote exploits. It is important to note that ninja cannot prevent
       attackers from running exploits, as a successful exploitation only will be detected AFTER the attacker has gained root. However, when ninja is running with a
       short  scanning  cycle,  this detection happens nearly immediately. The security lies in the fact that we stop the attacker before he/she has time to do any Äê
       thing nasty to the system, and it gives us the opportunity to disable the attacker's shell access, and lock him/her out of the system.

       In an ideal environment, ninja should be run together with kernel hardening systems such as grsecurity (www.grsecurity.net) as this will allow for some  pro Äê
       tection of the ninja process.

       This is not a complete security system. Do not rely on it to keep your system safe.


BUGS
       Please let me know if you should stumble across any bugs or other weirdness.  I greatly appreciate all bug reports, patches, ideas, suggestions and comments.
