Fixes from the Previous Release

 

  • Reporting: Certain Custom Reports were incorrectly limiting the results to the Top 10 occurrences.
  • Impersonation Protection: A confirmation dialog was incorrectly being displayed when you tried to save a definition after you changed the action from “Hold for Review” to “Bounce”.

 

New Features

 

  • Audit Logs: The release of the previously communicated updated Audit Logs page has been moved.
  • Impersonation Protection: Based on customer requests, a log area for Impersonation Protection has been made available under the Monitoring section.
  • Data Leak Prevention: Based on customer requests, a log area for Data Leak Prevention has been made available under the Monitoring section.
  • Roles: A new permission labelled “Remove Address from Purge List” has been added for the Internal Directories section offering you more granularity for administrative permissions.

 

Improvements

 

  • Account Settings: Under the “Directory Options” section the field where you can select a Directory Connector has been removed as it is now obsolete.
  • Continuity: When selecting the “Test Email Address” during the configuration of the Outbound Check on a Continuity Monitor the list of addresses to choose from will no longer include alias addresses.
  • Account Settings: Under the “User Access and Permissions” section you will now find an option to “Allow Weak Ciphers for Secure Receipt” giving you more control over TLS connections into the Mimecast MTA.

Great news! 

 

We now have dedicated logging for Impersonation Protection which will provide better visibility of potential impersonation attacks. In addition there will be enhanced logging for messages triggering Content Examination policies for your data leak prevention solution.

 

To find your logs navigate to Monitoring under the Administration section on your Mimecast Console. 

 

Just so you know Secure Messaging logging is also on it's way so keep an eye out for updates. 

 

We hope you find this useful!

New API Feature Release

 

Mimecast is pleased to announce that additional email security information for Targeted Threat Protection has been added to the Data Logging API. For customers subscribing to our Targeted Threat Protection URL Protect and / or Attachment Protect features, additional information is available for malicious activity detected by Mimecast.

 

  • For URL Protect, all links scanned by Mimecast that are found to be malicious will be logged.
    • The data logs include the malicious URL clicked, and the transmission details of the original email containing the URL:
      • from address,
      • recipient address
      • source IP address
  • For Attachment Protect, all files found to be malicious when processed by the sandbox will be logged.
    • The data logs include comprehensive details about the malicious file:
      • md5, sha1, sha256 hashes
      • name
      • extension
      • MIME type
      • size
    • as well as the transmission details of the original email that the file was attached to:
      • from address,
      • recipient address
      • source IP address

 

This new data about malicious URLs and attachments detected can be used for a number of use cases, for example,

 

  • as a data source for SIEM systems to:
    • alert on malicious events,
    • aid in incident response investigations,
    • and to demonstrate the value of the TTP service internally,
  • as a data source for analytics applications,
  • as a data source to update other gateway security appliances and intrusion detection systems.

 

For further information please the Understanding the Data Logging API guide.

As part of the Administration Console refresh project, we're pleased to announce that we'll be refreshing the Audit Logs section.

Mimecast Personal Portal v2 to be retired May 25th 2017

 

As we continue to build the latest version of Mimecast Personal Portal (v3) for the future, we would like to inform you that Mimecast will be retiring Mimecast Personal Portal v2.

 

Mimecast Personal Portal v3 has been available since late 2015 and many customers have already directed their end users to it. These are the Key differences between Mimecast Personal Portal v2 and v3. Our ongoing development continues to add additional features, new services, security enhancements and improvements to performance on v3 only.

 

Administrators can take advantage of the latest capabilities now by Directing Users to Mimecast Personal Portal v3. An enforced redirect to Mimecast Personal Portal v3 will take affect from May 25th, 2017. Enablement Assets are available from the Asset Library on the Mimecaster Central community to assist with user education on the new experience.

 

If you would like to speak with someone or require further support in moving to Mimecast Personal Portal v3, please contact your Account Manager.

Fixes from the Previous Release

  • User Profile: We’ve removed some spacing issues on the message that opens when you click the name of your Customer Advocate on the Account and Support Details window.

  • Audit Logs: The log that gets written for Directory Sychronizations has been updated.
  • SMS Dashboard: When reviewing the SMS status you can now see the full Failure Reason for SMS messages that have a status of “Failed”.

Mimecast is happy to announce the following improvement to our DNS Authentication - Outbound Signing policies.

Please note that if you wish to update your current Outbound Signing policies/definitions to use the new key length of 2048 bits, a new DNS Authentication - Outbound Signing Definition will need to be created with the new key length.
