Prevention is the measures taken to proactively avoid cyber threats and attacks by implementing various security controls, focusing on reducing vulnerabilities, strengthening defenses, and implementing proactive security measures.
Detection involves actively monitoring systems and networks for signs of security breaches or unauthorized activities. It aims to identify and alert on potential threats as early as possible, enabling a swift response and mitigating potential damage.
Reaction refers to the actions taken in response to a detected security incident or breach. The goal is to contain the incident, minimize its impact, investigate the cause, and initiate the appropriate response measures.
