What should be monitored to identify inactive hosts in a CrowdStrike Falcon environment?

Monitoring the last seen date and time is essential in identifying inactive hosts within a CrowdStrike Falcon environment. This approach allows administrators to determine when a device last communicated with the Falcon platform. If a host's last seen timestamp indicates that it has not communicated for an extended period, it can be flagged as inactive. This helps ensure that all devices actively participating in the network security posture are still operational and receiving necessary updates.

Inactive hosts can pose security risks, as they may be vulnerable to threats and may not be receiving timely updates or patches. By keeping a close eye on the last seen data, organizations can take proactive measures to investigate and remediate any potential issues, such as connectivity problems or non-compliance with security policies.

While event logs, total CPU usage, and network speed can provide useful information about host performance and activity, they do not directly indicate whether a host is inactive. Event logs record events and transactions but won’t reveal the last time a device was online. Total CPU usage may reflect the activity level of a host, but high CPU usage does not imply that the device is actively communicating with the Falcon console. Network speed can indicate performance but lacks the necessary context to determine a host's operational status over time. Thus, focusing on the last
