What is the kernel process for Content Awareness that collects the data from the contexts received from the CMI and decides if the file is matched by a data type?

The cntawmod is the dedicated Content Awareness kernel module. Its primary function is to collect data from contexts provided by the Content Management Interface (CMI). After receiving the data, cntawmod performs the initial analysis to determine if the file or data stream matches a configured Data Type. This kernel-level operation allows for efficient, early-stage filtering before potentially passing the data to user-space daemons for more intensive inspection.

B. cntmgr: This is the Content Awareness manager, a user-space process that is part of the dlpda daemon, not a kernel process.
C. dlpda: This is the main Data Loss Prevention (DLP) daemon, which operates in user space to perform deep content analysis, not the initial kernel-level matching.
D. dlpu: This is the DLP update process, a user-space utility responsible for fetching and applying DLP updates, not for real-time data inspection.

In the "Architecture and Debug" section, under "Processes and Daemons", it explicitly states: "The Content Awareness kernel module (cntawmod) collects the data from the contexts received from the CMI and decides if the file is matched by a Data Type."
