Shiela is working at night as an incident handler.

In the context of incident handling, the "point of contact" list is essential for ensuring that Sheila, the incident handler working at night, can quickly notify the responsible personnel within the organization about the cyberattack. This list typically includes the contact information of key stakeholders and decision-makers who need to be informed about security incidents, allowing for timely communication, decision-making, and response coordination.

References:Incident Handler (CREST CPTIA) courses and study guides stress the importance of having a well-maintained point of contact list as part of an organization's incident response plan to facilitate efficient and effective communication during and after cybersecurity incidents.
