Techopedia Explains Computer Security Incident Response Team

There are three main groups of services provided by a CSIRT:

  1. Reactive Services are the main sources of work of a CSIRT where the CSIRT responds to the actual event.
  2. Proactive Services are actions to prevent incidents from occurring in the future.
  3. Security Quality Management Services do not involve incidents, but rather include working with IT or other organization departments in which CSIRT members help solidify security systems.
