Incident response or incident managment
Concepts related to Incident Response
A Security Operations Center (SOC) is a team within an organization that monitors systems for security events and focus on incident response. They may use a SIEM tool.
Monitoring is an important part of Incident Response.
Log management is one important field of IT security operations. You can read more about it, SIEM and SOAR on this post.
It is important to take into account the Indicators of Attack (IoA) and Indicators of Compromise (IoC). They are for networks what signatures are for viruses.
Incident Response Standards
Standards for incident response:
- ISO/IEC 27035-1
- NIST SP 800-61
- ENISA’s Good Practice Guide for Incident Management
- CSA CIR
ISO/IEC 27035-1 is about IT incident management.
NIST SP 800-61 has the title “Computer Security Incident Handling Guide” You can read more about it on this external link.
“Good Practice Guide for Incident Management” is published by EU agency ENISA. You can read it on this external link.
“Handbook for Computer Security Incident Response” by Carnegie Mellon University SEI. It can be downloaded from this external link.

Computer Security Incient Response Team
The, term CSIRT, as an acronym for Computer Security Incident Response Team or Cyber Security Incident Response Team is used to design a group of experts that handles computer security incidents.
A Computer Emergency Response Team (CERT) used to define a CSIRT, more extended in the USA.
As computer threads started to appeared after the development of the internet on the late 80s, there was a need to create teams that knew how to handle computer security incidents.
A CSIRT could belong to a public institution (e.g., CISA-CERT, that belongs to American CISA) or a private organization (e.g., Amazon SIRT, that belongs to Amazon). Some CERTs have an international scope, while some other are more focused on a country.
Many countries have an official CERT, whose goal is to provide cyber security to their citizens and organizations.
The first team called CERT was CERT-CC, created in 1988. It belongs to the Carnegie Mellon University (USA).
At the beginning of the 90s, CSIRT were starting to be created in the European Union under the TERENA program.
In 1989, FIRST (Forum of Incident Response and Security Teams) was founded. It is a global association of CERTs, and some of the most important ones over the world belong to FIRST association.
You can find all CERT teams belonging to FIRST on this link.
