Question
After enabling an IOA rule and its respective rule group, what else must be done for an IOA to be fully functional?
A. Nothing else needs to be done; the rule should start working
B. The rule group must be assigned to one or more prevention policies
C. The rule needs to be manually triggered to ensure it works as intended
D. You must individually select which hosts you would like to apply to rule to
Answer
B. The rule group must be assigned to one or more prevention policies
Explanation
After enabling an IOA (Indicators of Attack) rule and its associated rule group in the CrowdStrike Falcon platform, there is one more critical step required to make the IOA fully functional and provide the intended protection. The rule group containing the enabled rule must be assigned to one or more prevention policies.
Prevention policies in CrowdStrike Falcon define the security configuration for groups of hosts or devices. By assigning the rule group to appropriate prevention policies, you ensure that the enabled IOA rule is actively applied to and protecting the hosts covered by those policies.
Simply enabling the rule and rule group alone is not sufficient. Without the step of mapping the rule group to prevention policies, the IOA will not be triggered on any hosts and thus will not serve its intended function of identifying and blocking attack activity. Prevention policy assignment is an essential part of fully operationalizing IOA rules.
It’s important to note that individually selecting hosts for the rule is not required (eliminating option D). Additionally, while manually triggering the rule for testing purposes may be helpful, it is not a mandatory step for the IOA to be functional (eliminating option C). Lastly, additional configuration beyond enabling the rule and rule group is needed (eliminating option A).
In summary, to make an Indicators of Attack (IOA) rule fully functional after initial enablement, the critical step is assigning its rule group to relevant prevention policies. This completes the activation process and ensures the IOA rule is protecting the intended hosts and devices.
