Action Required: Elimination of Single-DES Support

SCS Computing Facilities continually works to enhance computer security for the SCS community. The latest effort involves eliminating the use of single-DES (Data Encryption Standard) in favor of stronger cryptographic algorithms, contributing to a more secure computing environment. This change will require all users to change their SCS Kerberos passwords by Monday August 12, 2013. This includes passwords for your main SCS user account and any Kerberos instances that are also being used (i.e. /mail, /remote, etc.).

The passwords for your main SCS user account and any Kerberos instances can be changed by accessing the SCS Computing Facilities Instance Manager tool:

https://webiso.cs.cmu.edu/instance/

Alternatively, you can change these passwords via the command line on any Linux/Unix platform. Please see the following help page for more information about changing your password:

http://www.cs.cmu.edu/~help/accounts_passwords/password_overview.html

Support for single-DES will end on Monday August 12, 2013. After this date, any SCS Kerberos password that has not been updated will no longer work.

Please contact the SCS Help Desk at x8-4231 or send email to help@cs.cmu.edu if you have any questions regarding this service change.

Thank you for your attention,

SCS Help Desk
