The concepts of CERT, CSIRT and SOC are often associated with the response to computer attacks, but they are distinguished by their specific roles:
CERT
Computer Emergency Response Team: Usually operates on a large scale, often at national or sector level, focusing on managing cybersecurity incidents and thinking proactively to prevent cyberattacks. It stands out for its strategic and comprehensive prevention approach.
CSIRT
Computer Security Incident Response Team:Operates within organizations, with a focus on incident response to limit damage. More focused than CERT, it aims to react quickly and effectively to security incidents, in order to minimize their impact.
SOC
Security Operations Center: A continuous monitoring center for security incidents for a specific organization, the SOC supervises threats in real time, with advanced technologies to detect, analyze and respond to threats before they become major incidents. The SOC is often the first line of operational defense.
