Overview of Threat Prevention Service

Starting on June 25, 2018, ITS will be updating email filtering for the university email systems, Office 365 and Gmail. The threat prevention service will be comprised of two filtering services designed to reduce exposure to security risks, such as malware, viruses, and phishing attacks.

Links and Attachments

The threat prevention filters also provide protection against malicious links and unsafe attachments.

  • Links: All URLs are rewritten through Office 365. If a link is safe, you will still go to the intended location. If a link is unsafe, you will see a warning message.
  • Attachments: All attachments are scanned for malware and access to attachments considered unsafe will be blocked.

Spam and Phishing

Incoming email will be routed through multiple filters and anti-virus engines. How these filters score the message determines how the mail is delivered to you:

  • Safe messages will be delivered to your Inbox
  • Mail considered spam will be delivered to your Junk folder and will have a {SPAM?} tag in the subject line.
  • Unsafe mail (messages that are likely to be phishing scams or have a malicious purpose) is quarantined and will be deleted after 30 days.
    • Faculty, staff, and student employees: Mailboxes on Office 365 will receive a digest message that lists all quarantined messages from the past 24 hours (example below) and provides options for managing individual messages. Learn how to manage Spam-Quarantined messages.
    •  

    • Students: Quarantined messages will not be delivered to Gmail accounts. If you feel that you are not receiving all of your legitimate email messages, contact the ITS Help Center, and ITS will investigate the issue.

Technology solutions improve security but good judgement remains your best defense against phishing and other scams. Please be on alert for any threats that slip by our filtering, and remember that ITS and other University organizations will not send unsolicited requests for UConn credentials or other personal information.
