Email Security Enhancements

This news item expired June 10, 2011. It may contain out-of-date information.
In an effort to further enhance security on Iowa State's computer network, IT Services has implemented a new policy regarding email attachments. As of Thursday, May 19, attachments to emails that contain executable files will be blocked. The following file types, which may contain malicious, executable codes will be blocked from all emails entering or leaving Iowa State: *.bat, *.com, *.exe, *.hta, *.ico, *.pif, *.scr, and *.vbs.

These types of attachments are a common method for spreading malware, and filtering them is an industry best practice. Google already blocks these same file types on our student CyMail accounts. Adding this new policy to all email entering or leaving the Iowa State network will provide a more consistent email attachment policy campus-wide.

This policy is expected to have minimal impact to the campus community, as it will only affect those users who forward their email to non-Exchange or non-Gmail accounts. These file types have been blocked from Iowa State‘s Exchange servers for many years, now.
