A cybersecurity analyst has been notified of an active exploitation of a critical vulnerability within the organization's public facing web application. Which of the following incident response steps should the analyst perform FIRST?
Isolate the affected systems to prevent potential spread.
Inform senior management and other relevant stakeholders about the incident.
Conduct a lessons learned meeting to review the incident response process.
Initiate the recovery process to restore systems to normal operation.
During an incident, the analyst should prioritize containing the threat to prevent further damage or exploitation. Containment strategies may include isolating affected systems, blocking malicious traffic, or taking applications offline. Other steps, such as reporting the incident to stakeholders and recovery processes, occur after the immediate threat has been contained and the impact is controlled.
