What does the 'Actor change' trigger in policy management?

The 'Actor change' trigger in policy management indicates a situation where a change occurs in the status or role of an actor, such as a user or a device within a network environment. This type of change often necessitates a reevaluation of the security policies to ensure that access levels and permissions remain appropriate.

When an 'Actor change' is detected, it initiates an automatic policy calculation. This process does not require any manual intervention, allowing the system to swiftly adjust security policies based on the new parameters associated with the actor's role or status. This ensures that the network's security posture remains robust and that any risks associated with the change are managed effectively.

The other choices do not align with the core function of the 'Actor change' trigger. For instance, proactive updates on user access and manual policy changes by users both imply some level of user involvement or intervention, which contrasts with the automated nature invited by the trigger. Additionally, while a report on network activity is useful for understanding the broader context of policy management, it does not directly relate to triggering policy calculations based on changes in actor status.
