Course of action#

A course of action details a set of clear, specific recommendations and measures to mitigate an incident, address affected exploit targets, and effectively respond to a cyber threat.

The goal of a course of action can be preventing the potential occurrence of an incident, correcting a vulnerability so that it cannot be exploited, mitigating the consequences of an attack, or defeating an adversary.

Regardless of the goal, a course of action suggests the recommended actions to take in order to achieve the intended effect.

Create a course of action by selecting:

  • In the side navigation bar + Create > Course of action.

Or:

  • (Requires Beta: Intelligence creation on the graph)

    In the top navigation bar of a graph, select + and then Course of action to create a draft entity.

  • Double-click to open the newly created draft entity to edit it.

Then, Configure this entity.
