You are a cybersecurity analyst, and an advanced persistent threat (APT) has been detected within your organization's network. Which of the following actions would be the BEST approach to start the remediation process?
Re-image all affected systems
Remove the detected malware from the affected systems
Isolate the affected systems from the network
Restart all affected systems to restore normal operations
The best initial step in remediation is to isolate the affected systems to prevent further spread of the threat. This helps contain the attack and minimizes potential damage. Removing malware only without understanding its scope or re-imaging systems without proper isolation can leave the organization vulnerable.
