In the event of a major security breach, the network administrator should reference the Incident Response policy to determine the next steps. The Incident Response policy is a set of guidelines and procedures that dictate how the organization responds to security incidents, including how to detect, analyze, contain, eradicate, and recover from security breaches.

The Incident Response policy outlines the roles and responsibilities of various stakeholders in the organization, including the IT team, security personnel, management, and other relevant parties. It also defines the communication channels and escalation procedures that should be used during an incident, as well as the reporting and documentation requirements.

By referencing the Incident Response policy, the network administrator can ensure that the appropriate steps are taken to address the security breach, including identifying the root cause, containing the damage, mitigating the risk, and preventing future incidents. The policy provides a framework for a systematic and coordinated response, which helps to minimize the impact of the breach and maintain business continuity.

The other policies listed - Non-disclosure policy, Data loss prevention policy, and Acceptable use policy - may be relevant in certain circumstances, but they do not address the specific steps that should be taken in response to a security breach. The Incident Response policy is the most appropriate reference for this scenario.
