The dlpda (Data Loss Prevention Daemon) is the primary user-space process responsible for handling the logic of both the Content Awareness and Data Loss Prevention (DLP) software blades. Data from network traffic is intercepted by the firewall kernel and passed through the Content Management Interface (CMI) framework to the dlpda daemon. This daemon then performs the actual inspection, analysis, and classification of the data. Although the question specifies a "kernel process" and dlpda runs in user-space, it is the specific process that receives and processes the collected data, making it the correct answer in this context.

A. PDP: The Policy Decision Point (pdpd) is a user-space daemon associated with the Identity Awareness blade, responsible for enforcing identity-based policies, not content inspection.

B. cpemd: The cpemd (Check Point Endpoint Management Daemon) is a process related to the management of Endpoint Security clients and is not involved in gateway-level Content Awareness.

D. CMI: The Content Management Interface (CMI) is a kernel-level framework or interface, not a distinct process. It is the mechanism used to extract data from the kernel and pass it to user-space daemons like dlpda.

1. Check Point Support Center, sk113239, "Troubleshooting Content Awareness": In the "Solution" section, it explicitly states, "The main process for Content Awareness is dlpda." This identifies dlpda as the central process for the blade's functionality.

2. Check Point R81.20 Security Gateway Architecture and Performance Tuning Guide: On page 31, under the section "Application Control and URL Filtering / Content Awareness / DLP," the architecture is described: "The CMI gets the file from the Security Gateway kernel and sends it to the dlpda daemon for scanning." This confirms dlpda is the recipient and scanner of the data collected by the kernel.

3. Check Point R81 Security Gateway and Management Debugging Guide: The guide details the traffic flow for content inspection as Firewall Kernel -> CMIK (kernel module) -> CMI (framework) -> dlpda (user-space daemon). This illustrates that while CMI is the kernel component for data transfer, dlpda is the process that ultimately handles the data for Content Awareness.
