A PC security occurrence reaction group (CSIRT) is an assemblage of individuals entrusted with the troublesome accomplishment to address, auspicious and effectively, all episodes that influence the association. They are answerable for protecting the classification, respectability and accessibility (CIA) of the business' benefits (PC frameworks or systems) and information.
