CIRT - Computer Incident Response Team

What is a Computer Incident Response Team? (CIRT)
A CIRT is a carefully selected and well-trained group of people whose purpose is to promptly and correctly handle an incident so that it can be quickly contained, investigated, and recovered from. It is usually comprised of members from within the company. They must be people that can drop what they’re doing (or redelegate their duties) and have the authority to make decisions and take actions.
