Which of the following actions cannot be performed by Cortex XSOAR?

Cortex XSOAR (Extended Security Orchestration, Automation and Response) is a comprehensive security operations platform designed to enhance incident response and automate security processes. The core functionalities of Cortex XSOAR include automating incident response workflows, orchestrating different security tools to work together seamlessly, and managing threat intelligence to provide organizations with an enhanced understanding of the threat landscape.

While it is capable of handling various tasks related to automation and orchestration, conducting vulnerability assessments is typically performed by specialized tools that focus on discovering and evaluating vulnerabilities within an organization's infrastructure or applications. This task often requires dedicated vulnerability management tools that can scan systems and analyze security weaknesses in a targeted manner.

Thus, the action that Cortex XSOAR cannot perform is conducting vulnerability assessments, as this specific function falls outside the scope of its primary capabilities. Instead, Cortex XSOAR excels in integrating with those external tools that may handle vulnerability assessments, allowing for a more streamlined incident response process once vulnerabilities are identified.
