Today's topics:

Heartbleed OpenSSL vulnerability.

Cornell's IT Security Office has issued alerts about the recently discovered "Heartbleed" vulnerability in recent versions of the commonly used encryption protocol, OpenSSL (http://www.it.cornell.edu/services/alert.cfm?id=3141 and http://www.it.cornell.edu/services/alert.cfm?id=3139).

As of 11:00 AM on April 8, all of the public-facing services at CLASSE were updated to address this vulnerability. We constantly monitor our internet traffic and are actively performing security audits and scans of our network and systems. At this time, we do not believe it necessary for CLASSE personnel to change their CLASSE passwords. If we receive new information or recommendations that require action from CLASSE personnel, we will issue a revised statement.

New SSL certificates

As a precautionary measure in response to the Hearbleed SSL vulnerability, the CLASSE IT group generated new keys and SSL certificates for all of our affected publicly available services. This should have been transparent for most users and systems. However, depending on the configuration of your system and software, you might be notified that the certificate on the system you are connecting to has changed.

General network and server maintenance will occur every Tuesday from 12 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12 noon to 2:00 PM.
