Explanation

The best action to take by a security professional when a mission critical computer network attack is suspected is to prioritize, report, and investigate the occurrence. This means that the security professional should first assess the impact and urgency of the attack, then notify the appropriate authorities and stakeholders, and then conduct a thorough investigation to determine the cause, scope, and remediation of the attack. Isolating the network, installing patches, fixing the problem, redeploying the computer, turning the router off, performing forensic analysis, and applying the appropriate fix are all possible steps in the response process, but they should not be done before prioritizing, reporting, and investigating the occurrence.
