The phase of incident response where the incident is identified and analyzed is Detection and Analysis. During this phase, security teams utilize various tools and techniques to detect anomalies and potential incidents within the environment. This might involve monitoring logs, network traffic, and system activities for signs of malicious behavior or breaches.
Once a potential incident is detected, the analysis portion entails a deeper dive to understand the nature and scope of the incident. This involves gathering and examining evidence, determining the impact, and prioritizing the response based on the severity of the incident. Through thorough analysis, teams can classify the incident, discern affected systems, and begin to formulate an appropriate response strategy.
The other phases, such as Containment and Eradication, focus on controlling the incident's impact and removing the threat, while Recovery deals with restoring normal operations after an incident has been managed. Preparation is concerned with readiness for incidents before they occur, including establishing policies and acquiring necessary tools, rather than engaging directly with the incident itself. Hence, Detection and Analysis is pivotal for establishing an effective response to an identified incident.
