What method is commonly used to develop situational awareness during a security incident?

Developing situational awareness during a security incident is crucial for an effective response, and real-time monitoring of security alerts is the primary method used for this purpose. This approach allows security teams to receive immediate information regarding potential threats, anomalies, or breaches as they happen. By continuously analyzing alerts generated by security systems—such as intrusion detection systems (IDS), antivirus solutions, and firewall logs—teams can quickly identify and assess the nature and scope of an incident. This enables them to respond effectively to contain and mitigate the impact of the incident.

The other methods listed, while valuable in overall security management, are not as immediately applicable to developing situational awareness during an ongoing incident. Conducting post-incident reviews occurs after the fact, which means it focuses on analyzing what happened rather than providing real-time insights. Engaging all employees in security training enhances overall security posture but does not directly provide situational awareness of ongoing incidents. Lastly, periodic vulnerability assessments are important for identifying potential weaknesses but do not provide immediate information about current security events. Hence, real-time monitoring stands out as the most effective and relevant method for developing situational awareness during a security incident.
