Email Security

Summary

Email security is primarily supported through the Microsoft Office 365 Email service.  All email is filtered and sanitized by this service before delivering to users and other services including O365 mailboxes, Gmail, and other forwarding services.  User experience and functionality may be slightly different depending on where your mailbox is maintained and this document is intended on providing a high-level overview only.

Body

Email is a core tool that nearly every member of the community depends on every single day. We recognize that email is also a personalized tool, and that each user interacts with their inbox in a unique way.

Unfortunately, email is also an open door to malware, phishing and spam that, left unchecked, poses security threats to user productivity, user and college data, and financial loss.

Our mission is to strike a balance to make this service as personal, efficient and dependable as possible, while maintaining a level of security that protects our users from these threats.

Dartmouth employs multiple technology solutions to secure mail for our end users. Our technology and tools may change over time to address new and emerging threats, but the tools we employ provide the following capabilities you should be aware of.

Automated systems monitor inbound and outbound email to detect and identify threats

  • Automatically Scan all Email, Links and Attachments for malware, malicious sites, phishing and scams
  • Automatically Monitoring Email traffic for suspicious sending patterns and spoofing
  • Post-delivery analysis of past events to identify more advanced attacks over time

Automated systems are employed that can take the following actions in response to detected threats

  • Deny delivery
  • Place message in junk
  • Remove malicious messages after delivery

Automated systems flag suspicious messages for analyst review

  • In response to user reports of missed phishing attempts or spam/junk
  • In response to user reports of false positives or missing email
  • In response to highly suspicious or impactful events that may require additional follow up

If an email gets past our tools and makes it to your mailbox, please forward that on to our phishing mailbox: phishing@dartmouth.edu.

If you have any questions or concerns, please contact us so we can investigate.
