4/8/2014 - Windows XP End-Of-Life and CAT supported systems
Written by Janaka Jayawardena   
Thursday, 03 April 2014

On Tuesday, April 8th, 2014, any CAT supported (Tier 1 or 2) Windows XP systems will be switched to a restricted network access mode.  These computers will only be allowed to communicate with CAT Windows services (so that basic system plumbing that it needs to function are possible).  There will be no INBOUND or OUTBOUND network access permitted to these systems beyond the basic CAT supplied services provided.

End of Life for Windows XP Systems
Written by Janaka Jayawardena   
Thursday, 06 March 2014

On April 8th, 2014, after 12 years of service, Windows XP is finally reaching its support End of Life.

This means that security updates and patches will no longer be available for Windows XP. Unpatched systems are a security liability and cannot be left networked (ie: exposed to other MCECS computers and the Internet).

After April 8, any CAT supported machines in MCECS which need to continue running Windows XP for software/hardware compatibility reasons will need to be be converted to Tier 3 (unsupported) systems and effectively disconnected from our network

Beware of Spear Phishing Spam and giving out your passwords
Written by Janaka Jayawardena   
Monday, 30 September 2013

This is our periodic notice to warn people of dangerous e-mail spam - namely Phishing Spam.  We deal with a few waves of these at the start of term and Fall 2013 is shaping up to be a strong phishing season.  A few recent victims have been costly, leading to main PSU mail servers being blacklisted over the weekend, so please take note.

The CAT and OIT will NEVER ask for passwords via e-mail.

DO NOT follow links in your e-mail that require you to enter your login and password information.

DO NOT send out any unencrypted, sensitive information via e-mail.

Dropbox in MCECS - Usage, Security and Privacy concerns
Written by johnj   
Thursday, 10 November 2011

Dropbox, an online file repository/backup service, has been gaining in popularity. Its ease of setup and use for personal systems has resulted in rapid adoption among people trying to sync and transfer data between home desktops, laptops and other mobile devices.

We are seeing increased use of this service among faculty, staff and student users. While Dropbox is a hit at home, it has had a rocky road trying to adapt to corporate and centrally driven IT environments - both at a technical and policy level. MCECS users face many of these same challenges.
