This document provides an overview of managing the infrastructure components of a Computer Security Incident Response Team (CSIRT). It discusses the key components of a CSIRT infrastructure, which include the physical location and security of staff and data, office and home equipment, networks and defenses, tools and applications used for incident handling, and data repositories. It outlines that securing this infrastructure involves protecting data security, physical security, equipment, networks and systems, and CSIRT tools. In particular, data security is important because CSIRTs receive sensitive intellectual property and log files from their constituencies.
