Until then, OpenSSH is available on the web at Mac OS X.org and other related sites. Keeping the system updated with the latest patches and software versions is also a great way to stay secure. As exploits are found in a particular software package, a company will release a patch or revision that will help close the hole. Apple will probably assist Mac OS X users with this task better then most other UNIX distributions but this remains to be seen. It might be required that the user be aware of these issues.
File permissions are a particularly sensitive area with regards to security.
In its basic state, file permissions are of no consequence. When sharing methods are opened, however, these same permissions become a very large part of system security. It is not easy to modify the file permissions from the Graphical User Interface in Mac OS X but anyone who decides to dive into the CLI should take special care not to create any security holes when issuing commands via the command line. Information about file permissions and the CLI in general may be found in Mac OS X.org s CLI Tutorials. The key to secure commuting in the Mac OS X world is to be conscious of the environment, to stay up to date and to cautious of any changes made.
