SecureIt

If you're looking for a free and easy-to-use tool to protect your Darwin or OS X system, SecureIt could be just what you need. This Perl script is specifically designed to address the security hole that can be exploited when booting in single-user mode, which is inherently vulnerable due to its back-door nature. While this may serve a purpose in large networks with Unix systems and a missing sys admin, it's not an option for those who want to eliminate potential security risks.

Installing SecureIt is a breeze, and simply involves opening a terminal window, su-ing to root, and entering your root password. From there, navigate to where you downloaded secureit.tar.gz and unpack it with the command "tar xvzf secureit.tar.gz". Once you've changed directories to secureit, you can run the installation script with the command "./install".

It's important to remember that if you forget both your root password and single-user password, there are ways to reset them. While SecureIt does provide a substantial increase in security, it's not foolproof and you should consider using other measures to fully protect your computer. Overall, SecureIt is a valuable resource for those seeking to close common security gaps and better safeguard their system.
