The NetWitness 126.96.36.199 release provides new features and enhancements for every role in the Security Operations Center.
The Log4j vulnerability recently discovered in the commonly used open source logging library has been addressed. This applies to CVE-2021-44228. For more information, see the Security Advisory for Log4j.
Note: This patch release of NetWitness addresses log4j vulnerabilities reported till date. The following CVEs were validated and found to be not exploitable.
NetWitness will continuously monitor this issue for new developments and provide periodic updates.
Note: If you have the Export Connector plugin in your deployment, you must do the following:
- If you have Logstash installed separately, not as part of the NetWitness installation, you must uninstall the Export Connector plugin and install the updated Export Connector plugin after 188.8.131.52 patch upgrade. For more information to install the updated plugin, see Post-Upgrade Tasks on the Upgrade Guide for 184.108.40.206
- If you have Logstash installed as part of the NetWitness installation on the Log Collector service, the updated Export Connector plugin will be automatically installed during the 220.127.116.11 patch upgrade.
In both the above cases, the old Export Connector plugin files are not automatically removed after upgrade. You must remove the old plugin files, so the scans do not list them as vulnerabilities. For more information on how to remove the old plugin files, see see Post-Upgrade Tasks on the Upgrade Guide for 18.104.22.168

Pre-stage the upgrade repo to minimize downtime
Administrators can pre-stage the upgrade repository by downloading the required packages (.zip) without affecting the system. This minimizes the upgrade downtime and ensures the upgrade is completed within the planned time. The Pre-Stage Host option is available on the NetWitness UI and requires the NetWitness Server Host to be connected to Live Services. For more information, see Hosts and Services Maintenance Procedures topic in the Hosts and Services Getting Started Guide.
Note: You can use this feature only if you upgrade from 18.104.22.168 to a higher version.

Additional health-check utility is introduced for Administrators to analyze the current NetWitness setup and identify conditions that may impact the upgrade. If any issues are detected, the issues can be resolved before proceeding with the upgrade.
The pre-upgrade check verifies the following:
(Component Hosts) Node X Service Status - Verifies the status of services (Active or In Active) on all the Node X.
(Component Hosts) Node X Certificates Check - Checks the certificate expiry, missing, corrupted, and issuer mismatch in all categories of Node X.
CPU-Memory Info - Provides CPU and Memory details along with the real-time available memory.
(Admin Server) Node 0 File System Utilization - Verifies the disk partition utilization of /var/netwitness/mongo, /var/netwitness and root on Node 0.
(Component Hosts) Node X File System Utilization - Verifies the disk partition utilization of /var/netwitness/mongo, /var/netwitness and root for ESA Primary, Endpoint Log Hybrid, and UEBA services on Node X.
Mongo File (ESAPrimary) - Checks the ESA Primary node in the system and verifies the permission mode of mongo file.
Orchestration Server Normal Mode - Checks if the orchestration service is running in normal or safe mode.
(Admin Server) Node 0 Init status - Checks if there are any issues that might fail init process.
(Admin Server) Node 0 closed ports - Checks if the service ports required for NetWitness services are open and listening on Node 0.
(Component Hosts) Node X closed ports - Checks if the service ports required for NetWitness services are open and listening on Node X.

Concentrator, Decoder, and Log Decoder ServicesConcentrator, Decoder, and Log Decoder Services
Centralized Configuration Management Enhancements
The enhanced centralized configuration management allows administrators to:
Reconfigure 10G Network Decoders from the Policy UI. Administrators can quickly create 10G policies for each Decoder group based on the hardware profile.
Clone policy from an existing service to save policy transition time for existing users.
Restart only specific services within a service group that require changes. This minimizes potential downtime.
For more information, see Host and Services Getting Started Guide.
Enhanced Network Decoder to Support Load Balancing Deployments
When you shut down the Decoders, the network interfaces connected to the Decoders are automatically shut down. Then, the load balancers divert the traffic to other available Decoders. This enhancement will protect customers from data loss when they use load balancers to distribute traffic between several Decoders. For more information, see Configure the Decoder Capture Failover in Load Balance Deployments topic on Decoder and Log Decoder Configuration Guide.
