New Features

Signals and Incidents

Incidents are now part of WatchGuard EDR Core. When the Endpoint Security software detects a potential threat, it converts detected security events to signals. To make threat identification and resolution easier, Endpoint Security automatically combines related signals into dynamic incidents. Endpoint Security incidents group signals that previously generated multiple alerts and are part of the same attack.

• This release adds two new tiles on the Security dashboard: Incidents that Require Action and Incident Status. To open a filtered list of all incidents detected across the organization, click a tile.
• For each Endpoint Security incident, you can view the list of signals, the incident graph, and high-level details. You can also review the entities of interest related to the incident.
• You can add or remove and show, hide, or exclude signals.
• When you select a signal, you can view a tree that shows the processes that generated it, and the MITRE techniques and tactics used. You can also review the signal details.
• You can review specific details about the processes that generated signals.
• This release includes a new list that shows all incidents detected by Endpoint Security across the organization. You can filter the list and generate scheduled reports.
• The Detections section of Executive Reports now includes information about incidents: Incidents with Actions Required chart, Incident Status chart, and the Last Pending Incidents table.

• Malicious URLs detected are categorized as signals in incidents.
• An alert message shows on the Security dashboard when there are critical incidents that require immediate review.
• Incidents replace Indicators of Attack (IOAs) in the Endpoint Security management UI. IOA detections are now signals in the context of attacks. We have removed the Indicators of Attack dashboard and list, the IOA settings in My Alerts, IOA information in executive reports, and the recent IOA risk from the management UI. The RDP Attacks Settings and the Advanced IOA toggles remain in the management UI. Incidents in Endpoint Security are not the same as those in ThreatSync. Incidents in Endpoint Security are a group of signals generated from events on the endpoint, as well as Indicators of Attack.

Enhancements

• In the Workstations and Servers security settings, Advanced Protection settings were split into separate sections to simplify configuration: Zero-Trust Application Service, Anti-exploit, and Network Attack Protection. Existing settings profiles automatically reflect the new organization.
• We have updated the data retention policy for Endpoint Security products. This policy defines how long Endpoint Security data is retained on the cloud servers and available in the management UI. For more information on the data retention policy, go to this Knowledge Base article: New Data Retention Periods for Endpoint Security Solutions.
• Patch details now include installation status tiles that show the number of successful installations, download errors, and installation errors. These tiles do not include data from before this release and show data from your network and from the broader WatchGuard community.
• In a patch installation task, you can now configure required conditions that must be met for a patch to be installed. These conditions can include: time elapsed since the patch was released, minimum number of successful installations, maximum number of failed installations, and minimum number of days elapsed since the first successful installation. Each computer assigned the task must meet these conditions before the patch is installed.
• This release includes improvements to the update process for Windows endpoints:
• In Windows Pro editions, Endpoint Security updates no longer apply just before the computers restart, but also when you click Update and Restart or after the countdown in the restart message.
• To minimize disruption, Endpoint Security checks whether the endpoint meets the requirements to update the protection software before it shows an update or restart message. If the conditions are not met, the update does not start and the relevant status shows in the management UI.
• This release includes general improvements to protection and detection capabilities.
• Endpoint Security no longer uses temporary files to identify fileless malware detections. It now generates an incident from real data generated by the processes involved in the detection.
• By default, the Report Blocking to the Computer User setting is disabled.
• In a Workstations and Servers settings profile, Advanced Protection settings were renamed to Zero-Trust Application Service.
• In the Zero-Trust Application Service settings, the Audit operating mode for Windows computers is now renamed to Learning.

• Subscriber accounts with EDR Core allocated to their endpoints, but not deployed, can now start a trial of WatchGuard EPDR or Advanced EPDR and activate an Endpoint Risk Assessment.
• You can now download signature files over HTTPS.

Resolved Issues

• When the user is not logged in to the endpoint, WatchGuard Endpoint Security can now re-install with a restart after the scheduled wait time is exceeded.
• Duplicate computers no longer display when you use Active Directory to discover unmanaged computers.
• When you filter the Unmanaged Computers Discovered list and then select all filtered computers to install WatchGuard Endpoint Security on, the software now installs only on the computers in the filtered list.
• A fix was made to make sure that WatchGuard Endpoint Security sends executive reports and other scheduled daily reports as expected.
• When you disable a feature that uses the NAHSL network driver (for example, Advanced Protection, Web Access Control, or the Firewall), the NAHSL network driver is disabled.

Enhancements

• These enhancements were made in Windows protection v8.00.22.0024 and higher:
  • The software upgrade process was enhanced to make sure that Windows devices do not receive a BSOD error when EDR Core cannot stop a driver.
  • Improvements were made to prevent high CPU usage during computer startup when the Shadow Copies feature is enabled.

Resolved Issues

• These issues were resolved in Windows protection v8.00.22.0024 and higher:
  • A fix was made to prevent memory leaks on connections over port 8180 of the Java application that could cause the server to run out of memory.
  • The URL filtering feature prevents access to URLs configured as denied (for example, Facebook or YouTube pages).

For more information, review this Security Advisory Detail. This fix requires Windows protection version 8.00.22.0023 or higher.

Enhancements

• You can now isolate Mac computers on your network. Similar to the Windows feature, isolated Mac computers allow only WatchGuard Endpoint Security processes to communicate. If an attack occurs, you can isolate the computer from the network to prevent the spread of the threat. If required, you can exclude other processes to allow them to communicate on isolated computers. This feature requires macOS protection version 3.04.00.0000 or higher.
• To improve anti-tamper protection, you can now require two-factor authentication (2FA) when users try to log in to the management UI from their computers or uninstall the WatchGuard Endpoint Security product from their computer. 2FA uses a QR code you can generate for all computers in a customer account or, if you want to have different authenticator factors for different settings profiles, you can generate multiple QR codes. This feature requires Windows protection version 8.00.22.0023 or higher.
• Anti-tampering features now protect Windows computers when they start in Safe Mode. This setting is enabled by default. You can disable it in the management UI or from the Windows computer. This feature requires Windows protection version 8.00.22.0023 or higher.
• In the list of discovered computers, you can now select all unprotected computers.

Resolved Issues

• When a MAC address is not in uppercase letters, the security software can still discover unprotected computers.
• When you search the network for unprotected computers, the search results do not return protected computers that do not match the name in the list.
• Resolved an issue to make sure that antivirus exclusions are applied to decoy files. This fix requires Windows protection version 8.00.22.0023 or higher.
• Resolved an issue that caused a rare BSOD error when the server generated malformed network packages. This fix requires Windows protection version 8.00.22.0023 or higher.
• The zlib version was updated to resolve vulnerabilities in the previous version. This fix requires Windows protection version 8.00.22.0023 or higher.
• Performance improvements on virtual servers. This fix requires Windows protection version 8.00.22.0023 or higher.
