Question 273 - 300-710 discussion

To determine if a host is infected with malware, the network administrator can look at the Indications of Compromise (IOC) feature in Cisco FMC. The IOC feature analyzes network and endpoint data collected by Firepower sensors and AMP for Endpoints connectors, and identifies hosts that exhibit signs of compromise or infection. The IOC feature uses predefined rules based on Cisco Talos intelligence and other sources to detect IOCs on hosts.One of these rules is CnC Connected, which indicates that a host has communicated with a command-and-control (CnC) server that is known to be associated with malware activity2.

To view the IOC information for a host, the network administrator can navigate to Analysis > Hosts > Indications of Compromise in Cisco FMC, and select a host from the table. The IOC Details page will show the IOC events for that host, including the CnC Connected event, along with other information such as severity, timestamp, source, destination, protocol, and rule name.The network administrator can also view more details about each IOC event by clicking on it2.

The other options are incorrect because:

Analysis > Files > Malware Events shows information about files that have been detected as malware by Firepower sensors or AMP for Endpoints connectors.This does not show information about hosts that are infected with malware or have communicated with CnC servers3.

Analysis > Hosts > Host Attributes shows information about hosts that have been discovered by Firepower sensors, such as IP address, MAC address, operating system, applications, users, vulnerabilities, and so on.This does not show information about IOCs or CnC connections on hosts4.

Analysis > Files > Network File Trajectory shows information about files that have traversed your network and have been detected by Firepower sensors or AMP for Endpoints connectors. This allows you to track where a file came from, where it went, and what happened to it along the way.This does not show information about hosts that are infected with malware or have communicated with CnC servers5.
