Command and Control
Command and Control (C2) is a cybersecurity concept referring to the infrastructure and protocols used by attackers to remotely control compromised systems, such as malware-infected computers or botnets. It enables malicious actors to issue commands, exfiltrate data, and coordinate attacks across multiple targets. In defensive contexts, it also describes legitimate network management and incident response communication channels.
Developers should understand C2 to build secure applications that detect and mitigate malicious communication, such as in intrusion detection systems or antivirus software. It's crucial for cybersecurity roles, penetration testing, and developing defensive tools that analyze network traffic for suspicious patterns. Knowledge of C2 helps in implementing robust security measures to prevent data breaches and unauthorized access.
