The operations team of an organization has reported an IS security attack. Which of the following should be the FIRST step for the security incident response team?

Reporting results to management comes after initial assessment and containment, once there are substantial findings and a clearer understanding of the situation to communicate.

Documenting lessons learned is part of the post-incident phase, intended for improving future incident response capabilities and is not an immediate first step.

Performing a damage assessment is the crucial first step in incident response because it allows the team to understand the scope of the attack, identify affected systems and data, and determine the severity of the breach. This information is essential for effective containment, eradication, and recovery efforts, guiding all subsequent actions.

Prioritizing resources for corrective action occurs after the damage is assessed and containment strategies are being planned based on the incident's impact and scope.
