DESCRIPTION¶
The
Secure Compartment was designed to allow safe execution of priviliged
and/or untrusted executables and services. It has got all features possible
included, which can be used to minimize the risk of a trojanized or vulnerable
program/service.
COMMANDLINE OPTIONS¶
- --cap CAPSET
- sets the defined CAPABILITY for the process. See the README file
and the section LIMITATIONS for more information and examples.
- --chroot PATH
- chroots to the PATH defined. It has to be a valid chroot
environment. See the README file for more information and examples.
- --user USER
- runs the program with uid/euid of USER
- --group GROUP
- runs the program with gid/egid of GROUP
- --init PROGRAM
- runs PROGRAM before running the untrusted program/service, e.g. to build a
chroot environment
- --verbose
- prints detailled information what compartment does.
- --quit
- does not print syslog information about the use of compartment
- --fork

FEATURES¶
Linux Capabilities
- supports all Linux capabilites
- (see /usr/include/linux/capability.h and the README file)
Chrooting
- supports a chroot setup
Privileges
- supports running with defined user and/or group privileges
Setup Scripts
- supports running of initial scripts
- before running a program/service, e.g. to build a chroot environment.
LIMITATIONS¶
Currently the kernel does not allow capabilities on processes which are not
running with euid 0. Therefore
compartment will exit with an error if
--user and --cap is used together.
Please note that this will change for the 2.4 kernel.
