SPAM Filtering

All inbound emails are automatically analysed for SPAM or malcious content using a two staged approach:

  • Microsoft's cloud-based SPAM filter compares the email subject, sender, and message text with a database of known malicious/SPAM emails. Matching inbound emails are rejected;
  • Our CERN-hosted FireEye "EX" appliance analyses any email attachement by executing it in a virtulized environment. If the appliance manages to "detonate" malicous attachments or finds that the e-mail contains a malicious URL then the message is quarantined on the appliance. In such cases a recipient receives a notification asking to check if the message is legitimate or not.
