The Services Frameworks are high level documents detailing possible services that computer incident response teams (CSIRTs) and product incident response teams (PSIRTs) may provide. They are developed by recognized experts from the FIRST community. FIRST strives to include feedback from all sectors, including CSIRTs with a national responsibility, private sector CSIRTs and PSIRTs as well as other stakeholders. These documents were intended to provide a foundation for the development of new training material. However today they are used in a much wider scope, for example when defining an initial service catalogue for new teams. - first.org
