Which tool is used by a SOC analyst to quarantine an endpoint?

Cisco XDR (Extended Detection and Response) is a security operations platform designed to provide comprehensive visibility and response capabilities across multiple security domains, including endpoints, network, cloud, and email. A core function of XDR for a Security Operations Center (SOC) analyst is to orchestrate and execute response actions to mitigate threats. This includes the ability to isolate or "quarantine" a compromised endpoint directly from the XDR console. This action leverages an integrated endpoint agent (like Cisco Secure Endpoint) to sever the device's network connections, preventing lateral movement and further damage.

A. flow collector: A flow collector gathers and analyzes network traffic metadata (like NetFlow). It is a tool for visibility and investigation, not for taking direct enforcement actions on an endpoint.

B. syslog: Syslog is a standard protocol for forwarding log messages. A syslog server aggregates logs for analysis and alerting but does not have the native capability to quarantine a device.

C. load balancer: A load balancer's purpose is to distribute network traffic across multiple servers to optimize performance and availability. It is not a security tool for endpoint remediation.

1. Cisco XDR At-A-Glance. (Document ID: C45-744494-02, Published: 2023). In the "What you can do with Cisco XDR" section, it states, "Accelerate response actions such as isolating endpoints, blocking domains, and more with just one click." This directly confirms that endpoint isolation (quarantine) is a primary function.

2. Cisco Secure Endpoint User Guide. (Published: Latest Version). In the chapter on "Computers," the section "Isolating and Deisolating an Endpoint" describes the mechanism: "You can isolate a computer from the network to perform an investigation without the risk of the endpoint propagating a threat through the network." Cisco XDR uses this underlying capability as an orchestrated response.

3. Cisco XDR Data Sheet. (Document ID: C22-239000-00, Published: 2023). Under the "Key benefits" section, it lists "Remediate threats with confidence," and the text explains that analysts can "take decisive response actions in a single click from a single console," which includes endpoint quarantine.
