A company-wide early warning system can substantially aid the organization in detecting and responding to an ongoing attack. Employees must be sufficiently well trained that one who suspects he or she has been the target of a social engineering attack will immediately call the incident reporting hotline. In accordance with published procedures, the incident reporting personnel will immediately notify the targeted groups that an intrusion may be in progress so personnel will be on alert. In order for the notification to be timely, the reporting hotline number must be widely distributed throughout the company.
