Welcome Back Students

January 20, 2009

Dear Students,

Welcome back and Happy New Year! In order to begin the 2009 spring semester with minimal disruption to your network connectivity while keeping your assets and data protected, Carnegie Mellon University and the Information Security Office would like to remind you of the following safety tips:

1. Change your Andrew account password often and use a strong passphrase.
The Information Security Office recommends changing your password once every  90 days. A strong password or passphrase consists of letters, numbers and symbols.  For more information on how to manage your Andrew account password, visit Managing Your Andrew Account Password

2. Update your personal machine anti-virus and anti-spyware prior to connecting it to the Carnegie Mellon Network.

3. Monitor your bandwidth usage.
This will avoid jamming the CMU network with large bandwidth consumption and avoid losing connectivity for 45 days. Go to to monitor bandwidth consumption

4. Think before you click on attachments in email, instant messages, and untrusted web sites. If you don't know the source, weren't expecting a message, or if a message/website looks suspicious, do not click and ABSOLUTELY DO NOT PROVIDE ANY PERSONAL INFORMATION!  Verify first with a phone call or an independent e-mail.  One bad click can infect your computer, launch attacks on others, and result in network suspension until your machine is disinfected

5. Adhere to Copyright & Intellectual Property Laws.
Carnegie Mellon supports the fair usage of creative works.  At the same time, it is committed to protecting intellectual property and copyrights and takes a strong stance against any violations of these laws.   Non-compliance can result in disciplinary action or loss of network connectivity.  For more information, visit:

6. Visit the ISO Website often.
Visit often for security alerts, news, safe computing practices, training events and help with securing your computer.

7. Connecting your new machine.
If you have a new machine visit Computing Services, First Connect web page for step by step directions on how to secure and Register your computer.

As always, feel free to contact us at  Have a great semester!
