What does the Deep Security Agent (DSA) do after being enabled for Application Control?

The Deep Security Agent (DSA) plays a crucial role in managing application control within Trend Micro's Deep Security suite. When Application Control is enabled, the DSA takes a baseline scan of all executable files on the computer. This process establishes a reference point for what is considered legitimate and authorized executable software already present in the system.

By examining all executable files, the DSA can effectively manage and enforce policies that dictate which applications are allowed to run. This helps to prevent the execution of unauthorized or potentially harmful software, enhancing the security posture of the system.

This baseline scanning is essential for ensuring ongoing integrity and security because it helps identify any changes or installs that deviate from the established baseline. Such functionality is crucial in environments where control over applications and related software is critical for mitigating security risks.

In contrast, the other options do not accurately reflect the primary function of the DSA in the context of Application Control. The focus on executable files is a strategic measure to maintain security, distinguishing it clearly from scanning video files or monitoring installed software without establishing a baseline. Additionally, the DSA does not automatically update all software, which falls outside its intended use for application control and monitoring.
