Data Loss Prevention (DLP) Long-Term Support Release
Important - Trellix is enhancing our Trellix DLP release process to better serve our customers' requirements. This is achieved via defining each release as either a Long-Term Support release or Feature Release. Feature release introduces new features; whereas, Long-Term Support (LTS) release allows customers (under tight change control) to maintain a stable Trellix DLP version without changes to functionality and existing features. The LTS release will include only security updates, bug fixes, and some optimization for the existing features by releasing only patches or hotfixes. As is currently the case, these releases will continue to be fully installable packages.
Note
The latest LTS release for Trellix DLP Prevent is version 11.10 Update 4 (11.10.400).
For more information about LTS releases, see KB91807.
Updated platform, environment, or operating system support
Starting with this release, Trellix Data Loss Prevention Network Prevent is supported on Nutanix Acropolis Hypervisor (AHV).
For information on supported platforms, environments, and operating systems, see KB87112.
New or changed features
Integrating Trellix DLP Appliances with Microsoft Information Protection (MIP) — To integrate Trellix Data Loss Prevention Appliances with Microsoft Information Protection (MIP) you must have access to both Microsoft Purview Information Protection (called as MIP) and Microsoft Purview compliance portal (called as AIP). Integration of Trellix Data Loss Prevention Appliances with AIP allows you to use the functionalities of AIP including file encryption and data protection:
Allows you to integrate Trellix Data Loss Prevention appliances with AIP to act as a decryption proxy client (MIP client) and use valid AIP credentials to decrypt AIP protected files. Trellix Data Loss Prevention Appliances decrypt all data submitted for data protection analysis.
Users can apply sensitivity labels to the M 365 documents, PDFs, text files, email, and web uploads to comply with the company policy. You can configure sensitivity labels in AIP for different data protection policies either with encryption or without encryption.
You can use Labelinfo in MSIP classifications to support reading MIP label information or metadata in co-authored or auto-save enabled documents.
Underscore in exact data matching (EDM) — Legacy tokenization treats underscore as an alphabet and expects both scanning and indexing documents to match underscore regardless of its position. Starting with this release, underscore in EDM is:
Ignored, if a word is surrounded by underscore.
Considered as a word separator, if a word contains an underscore in between.
For example, in the mail ID xxxx_yy@zz.com, underscore is considered as a word breaker, and the mail ID is divided into two tokens, “xxxx” and “yy@zz.com”. An incident is reported even when the sample or scanned document has an underscore anywhere in a word, but the fingerprinted document doesn't.
Note
To apply the change in underscore tokenization, reindex exact data match fingerprint with the EDMTrain tool.
