The release 4.5 adds five new active lists that have a new, optional customer and customer URI fields optimized for MSSP users to support entries tailored to specific customers. These active lists are located in the ArSight Foundation/Common folder. More details in the release notes - https://www.microfocus.com/documentation/arcsight/security-content/ESM_4.5_RNs/

The release 4.4 adds six new rules and one dashboard to the Security Threat Monitoring package to help you monitor potential distributed denial of service, network denial of service, log enumeration, suspicious use of “powercfg” command to manipulate power settings, possible abuse of cloud management services and suspicious use of cloud administration commands. More details in the release notes - https://www.microfocus.com/documentation/arcsight/security-content/ESM_4.4_RNs/

The release 4.3 adds 4 new rules to the Security Threat Monitoring package to help you monitor your Windows and Linux environments. Checkout our new video series titled "Mastering ArcSight Series" on You Tube - https://www.youtube.com/playlist?list=PLN3aXmWqzjnGrnbr95kCs_J_SfxlPREuk.

The release 4.2 rebrands Galaxy Threat Acceleration Program to ArcSight Threat Acceleration Program (GTAP to ATAP) and exchanges all CyberRes references for ArcSight. Additionally, 4.2 adds new content to the Security Threat Monitoring and Threat Intelligence Platform packages to help you monitor command obfuscation, exfiltration to text storage sites, suspicious API activity, and communication to malvertising publishing domains/IPs.

The release 4.1 contains 12 new rules in the Security Threat Monitoring package to detect more cyber security attacks for the Windows Operating System, and added 3 new rules in the Threat Intelligence Platform package with very high confidence, and an active channel to display the very high confidence alerts. It also updated 8 rules.

"ArcSight ESM Default Content 4.0" release is a milestone release for the entire ArcSight portfolio.
In this release, the primary focus has been to support "CyberRes Galaxy Threat Acceleration Program (GTAP)" version 2.0. This is done through the "Threat Intelligence Platform" sub-package of the ESM Default Content package.

As you may read more from GTAP 2.0 Release Notes, ArcSight's Threat Intelligence support that is built-into ESM and the Default Content has been significantly improved. The most signifant change has been the introduction of many additional fields to have a richer feed with more SOC-ready context.

As such, Active Lists hosting the realtime IoC information, that are received from the realtime threat intel feed, as well as the rules/filters and other resources that utilize these active lists have been considerably updated.

As this was a significant change in the way the ESM resources worked, "deployment of ESM Default Content 4.0" now requires a couple extra steps that are specific to this release.

Please read this document in full, and preferably watch the following video, to get yourself acquantied with the process.
