Contents and detection

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

To improve data consistency, operating system names are now standardized for Asset Intelligence customers.
Guardian now implements a new experimental feature to group identical alerts to prevent redundant alerts. The feature is disabled by default and can be enabled through the Features section in the administration page.
By default, Common Vulnerabilities and Exposures (CVE) calculation should be skipped for Windows Common Platform Enumeration (CPE)s that are missing hotfix information. To turn off this behavior, you can specify the skip_windows_if_hotfixes_missing option in va cve options. For more details, see Configure vulnerability assessments.
CPEs generated by Asset Intelligence are rematched when new Threat Intelligence contents are reloaded.
Introduced support for the ingestion of manual contents for the TI for Mandiant AddOn.
Improved the consistency of the resolution of CVEs via hotfixes for Arc and Smart Polling.
