Suspected Malware detection, or ZHARA (Zero Hour Adaptive Risk Assessor), is Mimecast's proprietary software which provides early detection and prevention against zero day malware and spam outbreaks.

The Suspected Malware Policy is implemented by default.

These checks can be bypassed by implementing a Suspected Malware Bypass Policy. Mimecast recommends that this Policy should only be implemented in the event that regular attachments are getting blocked which need to be allowed through. Bypassing these checks could result in a new virus outbreak being undetected whilst signatures are being updated.

 

Encrypted ZIP files cannot be checked, although can be held using an Attachment Management Policy.

Benefits

This policy provides protection against previously unknown threats using deep level anomaly detection and trending against the entire Mimecast customer base.

What you need

  • An Administrator Console logon with access to the Administration | Gateway | Policies menu item.
  • A previously configured Suspected Malware definition.
