What type of actions can response policies permit during RTR sessions?

The correct answer highlights the capabilities of response policies during Real Time Response (RTR) sessions. During an RTR session, response policies are designed to allow administrators to perform various actions on endpoints especially in a live situation where immediate response is needed. One of the critical actions is running custom scripts and high-risk commands, which enables the administrator to execute specific tasks tailored to address threats effectively. This level of control is vital during incident response, as it empowers the administrator to take decisive actions against potential threats in real time.

This capability stands in contrast to the other choices. For instance, merely viewing host information provides limited interaction and does not facilitate active remediation. Similarly, applying updates to prevention policies or grouping hosts might be part of broader management activities, but they are not specific actions available during an RTR session focused on immediate threat response. Thus, the ability to run custom scripts and commands is a distinct and vital feature that supports an active response to security incidents.
