Fixes

20th June 2017 | v3.2.6

Mimecast is pleased to announce a continuous deployment of improvements to the Mimecast Personal Portal v3, containing the following enhancements and fixes:

 

Enhancements

  • Message list and message preview can be resized by dragging the vertical separator.
  • Changes to Archive folders:
    • An 'Include deleted folders' checkbox allows users to quickly display these folders should they need to recover a folder or message within the folder.
    • Deleted messages are always displayed inside any folder. This is especially important for customers who undertake mailbox management. Customers can still delete all messages older than a certain age whilst end users still get access to every message that's ever been in the folder.
    • We'd really love to hear your feedback on this feature in the FEEDBACK: New Archive folders Changes discussion.

 

Fixes

  • Various bug fixes and performance improvements.

Fixes from the Previous Release

 

  • Registered Applications: The Administration Console was incorrectly being displayed under the Services | Applications | Registered Applications section as it is intended to display all end user application registrations only.

 

New Features

 

  • Monitoring: An “Action” column has been added to the Impersonation Protection log page so that you can more easily see if an action was triggered for the logged item.
  • Login: On the login page you can now request a reset of your Cloud password when you have allowed such functionality on your Authentication Profile.

 

Improvements

 

  • Server Connections: When deleting a Server Connection the confirmation message now mentions the name of the connection that will be deleted.
  • Application Switcher: To better cover the function of the application the new “Discovery Reviewer” app has been renamed to “Case Reviewer”.
  • URL Protection: The validation performed when adding or updating Managed URLs has been updated so that it is less restrictive.
  • Report as: The confirmation message displayed after you have reported an item as Spam, Malware or Phishing has been reworded.
  • Policies: The Reputation Definition options have been updated as per the previously published Service Update blog post announcement.  
  • Server Connections: The “Test Connection” option now doesn’t only check for connectivity but also checks if the required application impersonation permissions have been granted.
  • Policies: When configuring Impersonation Protection policies you can now select the required definition via a “lookup” function instead of only being given a flat list without specifics.
  • Roles: Under the Monitoring harmonica permissions for the recently released Data Leak Prevention and Impersonation Protection log pages has been added. In preparation for a dedicated Secure Messaging log page permission for such logs have been added too.

Notice

As a part of some enhancements, we’ll be changing the reputation policy definition options for simplicity.  We’ll also be adding an extra list that will be checked during the reputation process.  

 

Status

Completed on 15 June 2017.

This change will apply to all regions from the week of Monday 12 June.

 

Action

No administrative action should be required but if you use this policy, please familiarize yourself with the below visual changes.  On the reputation policy definitions;

 

  • The number of 'hits' you can choose will increase from 5 to 6 to reflect the number of lists.
  • The 3rd party dynamic list option will be removed.
  • The 3rd party block list and Mimecast block list options will be rolled into one option providing coverage for all available lists.

Feature 

We're adding an option to the Targeted Threat Protection: URL Protect policy definition that will allow the removal of some external components from inbound messages.  You will see this option in the URL Protection definitions as 'Strip external source mode'.

 

Status

This will be rolled out from Wednesday 31st May onward.

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.
