Incident response refers to the collection of active measures taken during a cyber attack to stop the attack and mitigate the damage. It is important because it helps to minimize the impact of a breach and secure the network again as quickly as possible. Incident response plans should be developed in advance to ensure that the right people are in place to take action when an attack occurs. The incident response team is typically made up of security professionals, IT directors, threat operation counselors, legal representatives, and external security experts. They are responsible for developing incident response plans, identifying vulnerabilities and administering security programs.
There are several types of incident response, including:
- Preparatory incident response: This type of incident response involves creating and maintaining incident response plans, identifying vulnerabilities, and training staff on incident response procedures.
- Reactive incident response: This type of incident response is activated in the event of a security incident. It involves taking immediate action to contain the incident, identify its cause, and mitigate the damage.
- Forensic incident response: This type of incident response involves collecting, preserving and analyzing digital evidence in order to determine the cause of an incident and identify the perpetrator.
- Recovery incident response: This type of incident response involves restoring normal operations and returning the organization to a pre-incident state.
- Post-incident response: This type of incident response involves conducting a post-incident review, identifying lessons learned, and making recommendations for improvements to incident response procedures.
- Communications incident response: This type of incident response involves effectively communicating with stakeholders, such as employees, customers, and the media, during and after an incident.
