Release details

Component Version
MVISION EDR Client Extension
MVISION EDR Endpoint Snapshot Tool

Updated platform, environment, or operating system support

MVISION EDR Client is now compatible with:

  • SUSE Linux Enterprise Server 15
  • SUSE Linux Enterprise Server 15 SP1
  • RHEL 7.8, 8.0, 8.1, and 8.2
  • Ubuntu 18.04
  • CentOS 8.0, 8.1, and 8.2

Layer 7 visibility

In the Monitoring dashboard, when you select a network connection event, in the Event details card of the Process Activity pane, you can see network information related to Layer 7:

  • URL
  • Verb
  • Header Request
  • Header Response

You can also see URL and Verb information in the Network Connections filter in the Historical Search dashboard.

Tamper protection

The new tamper protection feature allows the Administrator to configure a policy to prevent a user from uninstalling MVISION EDR client without an uninstallation password.

Note: This feature is supported only on Microsoft Windows.

Improved visibility of events generated by Endpoint Protection

This release improves visibility and handling of events generated by McAfee Endpoint Security and McAfee MVISION Endpoint. This allows you to better detect threats or alerts related to EPP events.

Trace and network plug-in disabled by default

When the MVISION EDR Client is installed, the Trace and NetworkFlow plug-ins are disabled by default until MVISION EDR receives a policy from McAfee ePO that enables the plug-ins. The Default policy already has these 2 plug-ins enabled.

Important: On SUSE Linux Enterprise 15, netstat from the net-tools package is deprecated. If you want to run CurrentFlow Collector, installation of the net-tools-deprecated package is required.

Installation information

The MVISION Endpoint Detection and Response Installation Guide has the information you need to install the product for the first time and to migrate from McAfee® Active Response.

Important: macOS File Hashing exclusions have changed. See Information below.

If you install MVISION EDR 3.3.x Client extension on McAfee ePO for the first time:

  • The default MVISION EDR policy already has the new exclusions available as part of the default policy.

If you upgrade to MVISION EDR 3.3.x Client Extension on McAfee ePO:

  • File Hashing exclusions are added only as part of the default MVISION EDR policy.
  • File Hashing exclusions are not merged into the editable default policy. The user has to merge the new exclusions into their default policy.
  • Custom policies are not updated automatically. You have to manually update the File Hashing exclusions into your custom policies.

New exclusions added only for macOS
