Check what version of Mac OS X you have by clicking the apple in the left-most corner of the screen and then selecting “About this Mac”. A window will pop up and it will tell you what version of the operating system you have in this format: 10.X.x. 10.4.x is “Tiger,” 10.5.x is “Leopard,” 10.6.x is “Snow Leopard,” and 10.7.x is "Lion." The last number refers to software updates.
The following instructions are steps you must take now to ensure that your computer will be safe from viruses and other malware.
If you have arrived with an infected computer, or if it becomes infected while you’re here, you may lose access to the Internet until you clean it up. This may require you to reformat your hard drive and reinstall your operating system and all your applications from scratch. It’s up to YOU to take the necessary precautions to secure your computer.
CUIT recommends that you use these firewalls to help protect your computer from viruses and worms.
The following instructions will explain how to turn on automatic software updates. This will make it easier to keep up with critical updates that are released to protect your machine from dangerous viruses and other malicious programs.
Every time your computer finds new updates, you will see a notification message on your screen that new updates are ready to be installed. Do not ignore this software update message! Just say yes and allow the installation to proceed. After the installation is complete, you will usually be prompted to close down and restart your computer.
By default, Software Update is enabled and configured for weekly updates. To confirm that it is set up to do so, please follow these instructions:
In order to keep your machine safe from attacks, you need to protect all of its local accounts with secure passwords. A secure password is a combination of letters and numbers. It is something that would be very hard for you to forget, but virtually impossible for anyone else to figure out. If this password is forgotten, it cannot be reset. You may want to write it somewhere safe, but remember, if you write the password and keep it near your machine, anyone who finds it will be able to access all of your data and programs.
It is critical that you update your operating system regularly. Without doing so, your machine may not be stable and will be much more vulnerable to attack. In Step 2 of these instructions, you configured automatic updating of the operating system, but after connecting to the Barnard or Columbia networks for the first time, you must update manually.
Symantec (or Norton) AntiVirus is provided to all students in Columbia University and Barnard College for free. It will help in protecting you against viruses and other malicious programs.
