What is one of the main actions following the detection of malicious code in a system?

Implementing quarantining procedures is essential after detecting malicious code in a system. This action is vital because it helps isolate the infected system or the specific files that contain the malicious code, preventing it from spreading to other systems within the network. Quarantining effectively reduces the risk of further compromise and allows for a thorough examination and remediation of the threat without jeopardizing the integrity of other systems.

This action is typically one of the first steps in incident response and aligns with best practices in cybersecurity, as it helps maintain operational security during the investigation and cleanup phases. While notification of law enforcement, system backups, and compliance reporting may be relevant in broader contexts, they should occur after immediate containment measures like quarantining are established to ensure that the threat is controlled first and foremost.
