1.0 What’s New?

The following sections outline the key features provided by this release, as well as issues resolved in this release:

1.1 Introducing OpenSearch

Sentinel now uses OpenSearch and OpenSearch Dashboard for secure, scalable, and distributed indexing of events. It replaces Elasticsearch and Kibana, which were used in the previous releases.

This change has also provided Role-Based Access Control (RBAC) through the security plugins that comes bundled along with OpenSearch and OpenSearch dashboard. Role-Based Access Control (RBAC) and multi-tenancy are supported for the visualization features in the Sentinel. With the RBAC, you can provide the right access to the right users based on their permission level for accessing the visualization features. The multi-tenancy in the visualization provides greater flexibility for tenants by letting them control their dashboards or visualizations. The security plugins provide secure communication between Sentinel and OpenSearch as well as between OpenSearch nodes and out of the box. Node-to-node encryption is also enabled in OpenSearch by default. It prevents potential attackers from intercepting traffic between OpenSearch nodes and keeps the cluster always secure.It helps to reduce the risk from network-based attacks.

1.2 Integration With ArcSight Threat Acceleration Program (Basic)

Sentinel is now integrated with ArcSight Threat Acceleration Program (Basic). The basic feed provides threat intelligence, which is automatically incorporated into the threat monitoring content of Sentinel. With this integration, the real-time threat detection capability of Sentinel has been enhanced as it can now detect more threats in real-time by using the centralized event log analysis.

1.3 TLS 1.3 Support

Sentinel supports communication through TLS 1.3 in non-FIPS mode.

When Sentinel is configured for FIPS mode, the communication protocol automatically changes to TLS 1.2. This happens due to some limitations of JDK with TLS 1.3.

1.4 JDK Upgrade

Sentinel now supports JDK version 1.8_update372.

1.5 Library Upgrades

Several packages have been upgraded to address security vulnerabilities. The underlying libraries of CVE-2022-42889 are upgraded, though the security vulnerabilities did not directly affect Sentinel.

1.6 RHEL 8.7 Support

This release provides additional support for Red Hat Enterprise Linux version 8.7.

1.7 Deprecating Appliance Support

Starting October 2024, the ISO, VHD, and OVF appliance files will no longer be available on the product download site. For more information, contact the technical support team.

7.1 Sentinel Control Center (SCC) is not Launching

Issue: After converting to FIPS mode, in a specific case, SSC does not launch on executing launcher_controlcenter.exe. It waits for a single sign-on authentication page and displays the message Lost Connection.

Workaround: Reboot the system.

7.2 Unable to View Storage Capacity Forecasting Chart

Issue: The Storage Capacity Forecasting chart at Sentinel Main > Storage > Health, is not available. This is because Zulu OpenJDK does not include the necessary fonts.

Workaround: Use the following commands to install the fonts:

  • yum install fontconfig

  • yum install dejavu

7.3 Cannot Copy the Alert Links of All the Alerts in an Alert View in Mozilla Firefox and Microsoft Edge

Issue: The Select All <number of alerts> Alerts > Copy Alert Link option does not work in Firefox and Edge.

Workaround: Perform the following steps:

  1. Manually select all the alerts on each page of the alert view using the check box that allows you to select all the alerts.

  2. Click Copy Alert Link.

  3. Paste it in the desired application.

7.4 Login Screen is Not Displayed When Sentinel, Collector Manager, and Correlation Engine are Installed as an OVF Appliance Image

Issue: The installer halts at the installation in progress screen and does not display the login screen even though the installation is complete.

Workaround: Reboot the virtual machine and launch Sentinel, Collector Manager, or Correlation Engine.

7.5 Sentinel 8.6 Appliance in Microsoft Hyper-V Server 2016 Does Not Start When You Reboot

Issue: When Sentinel is deployed as appliance on Hyper-V Server 2016, Sentinel appliance does not start when you reboot it and displays the following message:

A start job is running for dev-disk-by\..

This issue occurs because the operating system modifies the disk UUID during installation. Therefore, during reboot it cannot find the disk.

Workaround: Manually modify the disk UUID. For more information, see Knowledge Base Article 7023143.

7.6 Installation of Collector Manager and Correlation Engine Appliance Fails in Languages Other than English in MFA Mode

Issue: Installation of Collector Manager and Correlation Engine appliance fails in MFA mode if the operating system language is other than English.

Workaround: Install Collector Manager and Correlation Engine appliances in English. After the installation is complete, change the language as needed.

7.7 Usability Issues in the Appliance Installation Screens

Issue: The Next and Back buttons in the appliance installation screens do not appear or are disabled in some cases, such as the following:

  • When you click Back from the Sentinel precheck screen to edit or review the information in the Sentinel Server Appliance Network Settings screen, there is no Next button to proceed with the installation. The Configure button allows you to only edit the specified information.

  • If you have specified incorrect network settings, the Sentinel Precheck screen indicates that you cannot proceed with the installation due to incorrect network information. There is no Back button to go to the previous screen to modify the network settings.

Workaround: Restart the appliance installation.

7.8 Collector Manager Runs Out of Memory if Time Synchronization is Enabled in Open-vm-tools

Issue: If you manually install and enable time synchronization in open-vm-tools, they periodically synchronize time between the Sentinel appliance (guest) and the VMware ESX server (host). These time synchronizations can result in moving the guest clock either behind or ahead of the ESX server time. Until the time is synchronized between the Sentinel appliance (guest) and the ESX server (host), Sentinel does not process events. As a result, a large number of events are queued up in the Collector Manager, which may eventually drop events once it reaches its threshold. To avoid this issue, Sentinel disables time synchronization by default in the open-vm-tools version available in Sentinel.

Workaround: Disable time synchronization. For more information about disabling time synchronization, see Disabling Time Synchronization.

7.9 Agent Manager Requires SQL Authentication When FIPS 140-2 Mode is Enabled

Issue: When FIPS 140-2 mode is enabled in Sentinel, using Windows authentication for Agent Manager causes synchronization with the Agent Manager database to fail.

Workaround: Use SQL authentication for Agent Manager.

7.10 Sentinel High Availability Installation in Non-FIPS 140-2 Mode Displays an Error

Issue: The Sentinel High Availability installation in non-FIPS 140-2 mode completes successfully but displays the following error twice:

/opt/novell/sentinel/setup/configure.sh: line 1045: [: too many arguments 

Workaround: The error can be safely ignored. Although the installer displays the error, the Sentinel High Availability configuration works as expected in non-FIPS 140-2 mode.

7.11 Keytool Command Displays a Warning

Issue: While using Keytool command, the following warning is displayed:

The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12which is an 
industry standard format using "keytool -importkeystore -srckeystore
 /<sentinel_installation_path>/etc/opt/novell/sentinel/config/.webserverkeystore.jks -destkeystore
 /<sentinel_installation_path>/etc/opt/novell/sentinel/config/.webserverkeystore.jks -deststoretype pkcs12".

Workaround: The warning is expected and you can safely ignore it. Although the warning is displayed, Keytool command works as expected.

7.12 Sentinel Does Not Process Threat Intelligence Feeds In FIPS Mode

Issue: In FIPS mode, when processing out-of-the-box threat Intelligence feeds from URLs, Sentinel displays the following error: Received fatal alert: protocol_version. This issue occurs because the out-of-the-box threat feeds now support only TLS 1.2, which does not work in FIPS mode.

Workaround: Perform the following:

  1. Click Sentinel Main > Integration > Threat Intelligence Sources.

  2. Edit each URL to change the protocol from http to https.

7.13 Logging Out From Sentinel Main Does Not Log You Out of Dashboards And Vice Versa in Multi-factor Authentication mode

Issue: In multi-factor authentication mode, if you log out of Sentinel Main you do not get logged out of Sentinel dashboards and vice versa. This is due to an issue in the Advanced Authentication Framework.

Workaround: Refresh the screen to view the login screen.

7.14 When you Open Sentinel Appliance Management Console an Error Message is Displayed

Issue: After upgrading to Sentinel, when you try to open Sentinel Appliance Management Console of the CE (Correlation Engine) or CM (Collector Manager) of HA (High Availability) servers, an error message Error 404 - Not found is displayed.

Workaround: For more information, refer to Micro Focus Knowledge Base document.

7.15 When you Launch the Visualization Dashboard as a Tenant User, an Error Message is Displayed

Issue: When a non-default tenant user launches the visualization dashboard, an error message Forbidden is displayed. This error message is displayed, whenever the dashboard is launched by the non-default tenant user who has View-only permission for the Management option and there is no user with Edit permission for the Management option under that tenant.

Workaround: Ignore the error message as there is no functionality impact.

7.16 In RHEL, RCM and RCE are not Connecting to the Server When CRL is Enabled

Issue: Remote Collector Manager (RCM) and Remote Correlation Engine (RCE) not able to connect to the server when CRL is enabled, in RHEL.

Workaround: Upgrade the cURL version on the machine to 7.60 or above.

7.17 RCM is not Forwarding the Events to the Sentinel Server When Event Visualization, FIPS, and CRL are Enabled

Issue: In the fresh installation of distributed setup, after enabling the Event Visualization, the FIPS, and the CRL services, the Remote Collector Manager (RCM) is not forwarding the events to the Sentinel Server.

Workaround: If either the Event Visualization and FIPS or the Event Visualization and CRL are enabled, then RCM forwards the events to the Sentinel server.

7.18 Incident Reports are Failing with Exceptions After Upgrading the Operating System

Issue: When you upgrade the Operating System, incident reports fail with exceptions.

7.19 Exception is Logged while Trying to Re-index for the First Time

Issue: An exception is being logged when the re-index operation runs for the first time.
