Checklist Summary The Benchmark is a compilation of security configuration actions and settings that "harden" Red Hat Linux operating systems. It is a CIS Level-I benchmark: the prudent level of minimum due care for operating system security. This benchmark was developed and tested on Red Hat Enterprise Linux (RHEL) including RHEL 2.1, RHEL 3.0, and Fedora Core 1, 2, & 3. It is likely to work for other Linux distributions - especially Red Hat and Fedora derivatives - as well.
Known Issues The actions listed in this document are written with the assumption that they will be executed in the order presented here. Some actions may need to be modified if the order is changed. Actions are written so that they may be copied directly from this document into a root shell window with a "cut-and-paste" operation. You may find that many of the "chkconfig" actions, which activate or deactivate services, produce the message "error reading information on service : No such file or directory." These messages are quite normal and should not cause alarm - they simply indicate that the program being referenced was not installed on your machine. As Red Hat Enterprise Linux installs allow a great deal of flexibility in what software you choose to install, these messages are unavoidable. The actions listed in this document are written with the assumption that they will be executed by the root user running the bash shell and without noclobber set. Also, the following directories are assumed to be in root's path: /bin:/sbin:/usr/bin:/usr/sbin. Before performing the steps of this benchmark, it is strongly recommended that administrators make backup copies of critical configuration files that may get modified by various benchmark items. If this step is not performed, then the site may have no reasonable back-out strategy for reversing system modifications made as a result of this document. The script provided in Appendix B of this document will automatically back up all files that may be modified by the actions below.
