Definition
Detection and Response refers to the processes and technologies organizations use to identify and address cybersecurity threats. It involves monitoring systems for suspicious activity and then taking swift action to contain and remediate any identified incidents. This proactive approach is crucial for minimizing damage, protecting sensitive data, and maintaining operational continuity. For instance, a Security Operations Center (SOC) might use an Intrusion Detection System (IDS) to flag unusual network traffic and then initiate incident response protocols. It is distinct from simply preventing threats, as it focuses on what happens after a potential breach is detected. This topic is commonly found in cybersecurity certifications like CompTIA CySA+ and CISSP.
