    2. Secure Your Computer Now Warning. This presentation is only a guide containing recommended security settings. It is not meant to replace well-structured policy or sound judgment. Furthermore this guide does not address site-specific configuration issues. Care must be taken when implementing these recommendations to address local operational and policy concerns. Some of the security precautions discussed here, if improperly implemented, can make your data inaccessible, not only to the bad guys, but also to you! Identity theft is a growing and very serious problem. Recently introduced state law and campus policy introduce measures designed to reduce the risk of identity theft. For these measures to be effective, we will all need to modify the ways we treat data.Some of the security precautions discussed here, if improperly implemented, can make your data inaccessible, not only to the bad guys, but also to you!

    27. Computing Security Standards I-D. Authentication - Passwords Remember: those networked HP printers that support telnet out of the box. They have an administrator account with no password. Some allow you to telnet out of the printer. Hackers love these because they can cover their tracks by hacking into someone’s server from a “printer”! The same rule should apply to those keypad door locks that are often left to their deafult key code: 1 2 3 4 5Remember: those networked HP printers that support telnet out of the box.

    28. Computing Security Standards I-D. Authentication - Passwords Important distinction between the first account set up on a Mac vs a Windows computer. On windows, this account is a full administrator account. Anything that account runs (like a virus) runs with full admin privs. On a Mac the first account is made a member of the admin group. This account can do administrative things if the user can supply their password. You can’t touch things in the system area without authenticating.Important distinction between the first account set up on a Mac vs a Windows computer.

    30. Computing Security Standards I-E. Personal Information Remember those grant proposals contain names and SSN’s of you co-PIs. You don’t want to have to send letters to everyone you’ve ever shared a grant with telling them that you’ve exposed them to identity theft because your laptop was stolen out of your office! If you need to preserve or archive information for a while, burn it to CD and delete it from your computer (Use Secure Empty Trash!). If you only need to keep the information for a while (gradebook), boldly mark the destroy date on the CD. And then destroy the CD on or after that date.Remember those grant proposals contain names and SSN’s of you co-PIs.

Secure Erase Trash immediately overwrites the file with erroneous data, so that the file disappears and cannot be reconstructed.
