| Security information is readily found at a number of Linux-related sites. The first to check, and stay abreast of, is always the vendor's site. Looking at http://www.novell.com/linux/security provides an overview of Linux-related security issues with links to a number of relevant pages. You should also keep abreast of issues and problems posted at http://www.cert.org and http://www.linuxsecurity.com. Information on any Linux command can be found through a number of utilities inherent in Linux: The man tool offers pages on each utility. For example, to find information about the setfacl tool, the command would be man setfacl. Most utilities have the built-in option of --help to offer information. From the command line, you can type setfacl --help to see a quick list of available options. The info utility can be used to view the man pages, as well for example, info setfacl. The whatis utility can show if there is more than one set of documentation on the system for the utility: whatis setfacl. The whereis utility will list all the information it can find about locations associated with a file for example, whereis setfacl. The apropos utility uses the whatis database to find values and returns the short summary information: apropos setfacl.
The customer should also be reminded that the Web is a great place to find help information on commands as well. |
