Contents and detection

A list of the improvements for the Contents and Detection that have been introduced in this release.

Alerts raised through Structured Threat Information Expression (STIX) indicators now set the corresponding STIX indicator identifier (ID) as Trigger ID, allowing for tuning based on specific indicators.
Nozomi Networks Operating System (N2OS) introduces the ability to distribute custom protocols via Threat Intelligence/Asset Intelligence, thus allowing new detection methods and asset identification strategies to be delivered on a daily basis.
The executable file scanner for all unknown protocols is on by default.
Improved resources auto-scaling for core N2OS processes resulting in optimized performance-to-resource-usage ratio.
Improve the memory handling of Common Platform Enumeration (CPE) maps for N2OS VA.
Improve the performance of Sandbox. More than eight workers can now be allocated to analyze files.
Improve the robustness and performance of N2OS Sandbox while processing files with unpackers.
Alerts of the types SIGN:ILLEGAL-PARAMETERS and SIGN:UNSUPPORTED-FUNC and SIGN:PROC:MISSING-VAR are now raised at most 10 times per hour for each link.
Improved the memory stability and dissection of Sandbox with respect to VBA macros.
