Explanation:
Some general categories of CSIRTs include, but are not limited to, the following:
Internal CSIRTs provide incident handling services to their parent organization. This could be a CSIRT

for a bank, a manufacturing company, a university, or a federal agency.
National CSIRTs provide incident handling services to a country. Examples include: the Japan CERT

Coordination Center (JPCERT/CC) or the Singapore Computer Emergency Response Team (SingCERT).
Coordination Centers coordinate and facilitate the handling of incidents across various CSIRTs.

Examples include the CERT Coordination Center or the United States Computer Emergency Readiness Team (US-CERT).
Analysis Centers focus on synthesizing data from various sources to determine trends and patterns in

incident activity. This information can be used to help predict future activity or to provide early warning when the activity matches a set of previously determined characteristics.
Vendor Teams handle reports of vulnerabilities in their software or hardware products. They may work

within the organization to determine if their products are vulnerable and to develop remediation and mitigation strategies. A vendor team may also be the internal CSIRT for a vendor organization.
Incident Response Providers offer incident handling services as a for-fee service to other organizations.
