FIRST is the Forum of Incident Response and Security Teams. The idea of FIRST goes back until 1989, only one year after the CERT(r) Coordination Center was created after the infamous Internet worm. Back then incidents already were impacting not only one closed user group or organization, but any number of networks interconnected by the Internet.

It was clear from then on that information exchange and cooperation on issues of mutual interest like new vulnerabilities or wide ranging attacks - especially on core system like the DNS servers or the Internet as a critical infrastructure itself - were the key issues for security and incident response teams.

Since 1990, when FIRST was founded, its members have resolved an almost continuous stream of security-related attacks and incidents including handling thousands of security vulnerabilities affecting nearly all of the millions of computer systems and networks throughout the world connected by the ever growing Internet.

FIRST brings together a wide variety of security and incident response teams including especially product security teams from the government, commercial, and academic sectors.

Security and Incident Response teams manage the handling of information security incidents within their organisation or network - their tasks broadly range from prevention and awareness raising, via incident detection to the actual tracking and resolving of incidents and drawing lessons from that. The Trusted Introducer Service - a.k.a. TI - was established by the European CERT community in 2000 to address common needs and build a service infrastructure providing vital support for all security and incident response teams.

The Trusted Introducer Service forms the trusted backbone of infrastructure services and serves as clearinghouse for all security and incident response teams. It lists well known teams and accredits as well as certify teams according to their demonstrated and checked level of maturity. Vital member's only services enabling security and incident response teams to interact more efficiently and effectively with each other are available to all accredited and certified teams.

Begun with a simple handshake and a fundamental mission, the CERT Division of theSoftware Engineering Institute (SEI) has evolved dramatically since it was created in 1988 as the CERT Coordination Center in response to the Morris worm incident. The small organization established to coordinate response to internet security incidents now has more than 150 cybersecurity professionals working on projects that take a proactive approach to securing systems.

Recognized as a trusted, authoritative organization dedicated to improving the security and resilience of computer systems and networks, the CERT Division is a national asset in the field of cybersecurity. We regularly partner with government, industry, law enforcement, and academia to develop advanced methods and technologies to counter large-scale, sophisticated cyber threats.
