Which types of custom IOA rules are supported by CrowdStrike Falcon on Windows, macOS, and Linux?

The correct choice highlights the comprehensive nature of the custom IOA (Indicators of Attack) rules supported by CrowdStrike Falcon across multiple operating systems, including Windows, macOS, and Linux.

Custom IOA rules are pivotal in detecting suspicious behavior based on specific patterns that may indicate a potential attack. The inclusion of network connection monitoring is crucial for identifying unauthorized communications to and from systems, which can signify exfiltration attempts or command-and-control activities. Domain name tracking allows for the detection of malicious or suspicious domain requests that could be linked to phishing or other types of cyber threats.

File creation and process creation rules are equally significant. Monitoring file creation can help detect the introduction of malware or unauthorized files into the system, while process creation rules are essential for observing the execution of processes that may indicate malicious activity, such as executing a payload or triggering an exploit.

The combination of these elements in the chosen answer illustrates a robust approach to threat detection, leveraging a wide range of behaviors that attackers may employ. This aligns with the platform's goal of proactive and comprehensive security monitoring.
