Computer security is an ongoing concern in schools. Choosing the best desktop security software for your school can be a challenge. The right security software will save you time, money, and headaches. There are two popular types of desktop security software: lock-down security and nonrestrictive security. Lock-down security restricts access to certain areas. Nonrestrictive security allows full access but clears changes at reboot or log-off.

What are the benefits of lock-down security software? Desktop security software restricts access to the desktop. As administrator, you determine what users can access on the computer. Look for popular features that allow you to:

• Restrict unwanted computer use; users cannot change desktop, file, and Registry settings

• Prevent software installations and downloads

• Lock icons so they cannot be moved, renamed, or deleted

• Secure files; restrict users from renaming, deleting, or altering files

• Lock files; block users from browsing the hard drive

• Customize security to users or groups

• Maintain a secure file system

• Confirm the software actually locks features and does not just hide them

• Ensures that the computer always looks the same and always works

• Verify that the security is active without having to reboot

• Control the software remotely using a network administration tool
