Which of the following is NOT a key feature of the Advanced Threat Protection Lifecycle?

The correct answer is that routine system updates are not considered a key feature of the Advanced Threat Protection Lifecycle. The Advanced Threat Protection Lifecycle focuses primarily on aspects directly related to identifying, responding to, and mitigating threats within an organization's network and systems.

In this context, incident containment is essential as it involves actions taken to limit the impact of a security incident, preventing further damage. Incident resolution entails successfully addressing and resolving security incidents, ensuring that the affected systems are restored to normal working conditions. Ongoing operation protection is vital, as it refers to the continuous efforts to shield the organization’s operations from potential threats over time.

While routine system updates are crucial for maintaining overall system security and ensuring that vulnerabilities are patched, they do not fall directly under the framework of the Advanced Threat Protection Lifecycle, which is more focused on the dynamic and reactive aspects of threat management rather than proactive maintenance through updates.
