CSIRT Action Areas
There are hundreds of CSIRTs in the world that vary in mission and scope. One of the chief ways to classify CSIRTs
is to group them by the sector or community they serve.
Below are some of the main types of CSIRTs in operation:
CRITICAL INFRASTRUCTURE CSIRTs
ACADEMIC CSIRTs
These response teams assist academic communities, universities, colleges, schools or institutes. Their size and facilities vary depending on
the size of the community, and they frequently
partner with other academic CSIRTs and may
specialize in research.
For a variety of reasons, including human resource limitations or a host of others, some companies elect to outsource CSIRT services instead
of internally creating and managing incident
response functions. This has spawned a robust
market for commercial CSIRTs, which offer incident response services to paying customers. The
relationship between a commercial CSIRT and its
client is often governed by service level agreements (SLAs), which are necessary to establish
incident response guidelines and to ensure information is handled according to the client’s needs.

In addition to serving a defined community, a
country’s National CSIRT usually takes on the role
of national coordinator for incident response,
and is the contact point3 for national and international incidents. The role and target community of a national CSIRT varies depending on its
roles and the existence of other response centers. For example, if there is no CSIRT designated for critical infrastructure, the national CSIRT
could assume responsibilities normally assigned
to a critical infrastructure response team.. It can
be considered as a “last resort CSIRT,” or one
which takes charge of incident response matters
that are not under the purview of another body4.
It is very common for various CSIRTs to be part
of the community the National CSIRT serves.
PROVIDER CSIRTs
Provider CSIRTs render services relating to specific products from a manufacturer, developer
or service provider. The purpose of this type of
CSIRT is to mitigate the impact of vulnerabilities or security issues related to their products.
Examples include HP CSIRT (Hewlett Packard),
Banelco CSIRT (Banelco Bank), or Adobe PSIRT
(Adobe) among others.
GOVERNMENT CSIRTs
COMMERCIAL CSIRTs

In some cases, there are CSIRTs specifically established for the protection of critical information assets and the critical infrastructure of a
nation, regardless of whether it is operated by
the public or private sector, or administering
transport, power generation, communications
or other processes. Since institutions reporting
to of this type of CSIRT can pertain to more than
one community (for example, both military and
critical infrastructure), it is vital to establish protocols for interaction with other teams involved.
NATIONAL CSIRTs

Definition
Government CSIRTs serve state institutions in order to ensure that government IT infrastructure
and the services it facilitates to citizens have an
adequate level of security. Government CSIRTs
adapt their structures to the Government. They
can meet local, regional or sector-specific government communities. Government CSIRTs can
operate independently or interact to combine
strategies and efforts and share resources and
knowledge. Within a country, for example, the
Ministry of Education and the Ministry of Tourism might operate independent CSIRTs, but regularly collaborate and share information.
MILITARY SECTOR CSIRTs
SMALL/MEDIUM-SIZED
ENTERPRISE (SME) SECTOR CSIRTs
Military CSIRTs provide services to the military
institutions of a country. Their activities are usually limited to the defense, or offensive cyber
capabilities, of a nation. In addition to standard
incident response technologies, they often have
specific ICT knowledge for military use including, for example, weapons and radar systems.
The size and nature of SMEs often do not allow
them to implement individual incident response
teams. Therefore, there is a need to create CSIRTs
that understand and address the needs of this
business community, such as the one implemented in Spain by the INTECO-CERT Corporation,
which focuses on assisting SMEs and citizens.
