About this Patch

ExtremeSecurity V7.7.2.8 Patch 9 is released and resolves 1 field issues reported from users and administrators. If you already installed ExtremeSecurity V7.7.2.8 Patch 8 Interim Fix 01, there is no need to install this update as there are no new resolved issues. This release follows up V7.7.2.8 Patch 8 Interim Fix 01 for customers who are not yet on V7.7.2.8 Patch 8 to prevent them from installing both Patch 8 and an interim fix.

Before installing this update, there are three important changes that administrators should be aware of if they did not install the previous ExtremeSecurity release (V7.7.2.8 Patch 7). This message is being included in the V7.7.2.8 Patch 9 release notes for visibility:

• TLSv1 is disabled in ExtremeSecurity V7.7.2.8 Patch 7 and above. This change was originally completed in ExtremeSecurity V7.7.3.0 and has been ported to the ExtremeSecurity V7.7.2.8 software stream as of V7.7.2.8 Patch 7. This means that Tomcat will no longer listen and actively refuse browser connections using TLSv1.0 after updating to ExtremeSecurity V7.7.2.8 Patch 9. Browsers will be required to use TLSv1.1 or TLSv1.2 to authenticate to ExtremeSecurity SIEM. This should only impact users with older or legacy browsers.
• The installation of ExtremeSecurity V7.7.2.8 Patch 9 and later updates the Java version to Java 8. This change was released as part of V7.7.2.8 Patch 7, but is also being noted for administrators in the release notes for V7.7.2.8 Patch 9 to ensure this change is communicated.
• The Master Console v0.10.0 or v0.11.0 is not supported on ExtremeSecurity V7.7.2.8 Patch 7, ExtremeSecurity V7.7.2.8 Patch 8, or ExtremeSecurity V7.7.2.8 Patch 9 due to changes made with Java 8 and TLSv1.0 connections as described above. Administrators who require the Master Console should not upgrade to a version above ExtremeSecurity V7.7.2.8 Patch 6.

The 7.2.8-QRADAR-QRSIEM-20170726184122 fix pack can upgrade ExtremeSecurity V7.7.2.4 (7.2.4.983526) and later to the latest software version. However, this document does not cover all of the installation messages and requirements, such as changes to memory requirements or browser requirements for QRadar. To review any additional requirements, see the ExtremeSecurity Upgrade Guide. If you are on a version of ExtremeSecurity earlier than ExtremeSecurity V7.7.2.4, you must upgrade to ExtremeSecurity V7.7.2.4 before proceeding to ExtremeSecurity V7.7.2.8.
