Computer Incident Response Team is an expert group that handles computer security incidents. Whenever a new technology arrives, it is invariably dogged by misuse like the first worm in the IBM VNET and Morris Worm that hit Internet and paralyzed it. This led to the formation of the first Computer Emergency Response Team at Carnegie Mellon University under U.S. Government contract. With the massive growth in the use of Information and Communications Technologies thereafter, the Computer Incident Response Team (CIRT) has come to stay as an essential part of large organizations.
No matter how well your network is protected, there are always incidents you are not prepared to deal with, by yourself. It may be because the problem is beyond your technical know-how for the necessary action to be taken. Security policy of a company is not complete until procedures are put into place for the handling and recovery from the incidents. The best solution is to include a Computer Incident Response Team (CIRT) within the company’s incident response procedures.
