What Is Command and Control?

Command and control is the communication mechanism an attacker uses to send instructions to a compromised system and receive status information, stolen data, or the results of executed commands. Certification exams may refer to this activity as C2 and ask candidates to identify unusual outbound traffic, repeated beaconing, or connections to suspicious infrastructure. Attackers may attempt to conceal command-and-control traffic inside encrypted web sessions, domain-name requests, cloud services, or other protocols that resemble legitimate activity. Egress filtering, network monitoring, domain reputation checks, segmentation, and behavioral analysis can help detect or disrupt these channels. Investigators should determine which systems communicated externally, what instructions were received, how long the channel existed, and whether additional payloads or data transfers occurred.
