CSIRT
A CSIRT, or Computer Security Incident Response Team, is a dedicated group of cybersecurity experts responsible for responding to computer security incidents and breaches. Their main goal is to minimize damage, resolve security issues, and restore normal operations quickly after an attack.
TECHNICAL DEFINITION
A Computer Security Incident Response Team (CSIRT) is a specialized organizational entity responsible for managing and coordinating an enterprise's response to cybersecurity incidents, encompassing detection, analysis, containment, eradication, recovery, and post-incident review to protect critical assets and ensure business continuity.
BACKGROUND
Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.
