The process of identifying, managing, and recovering from cybersecurity incidents.
Description
Security Incident Response is a crucial aspect of cybersecurity that involves a structured approach to managing the aftermath of a security breach or cyberattack. The primary goal is to handle the situation in a way that limits damage and reduces recovery time and costs. The process typically includes preparation, detection, analysis, containment, eradication, recovery, and post-incident review. Organizations establish an incident response team (IRT) that is trained to act quickly and efficiently when an incident occurs. For instance, in 2017, the Equifax data breach exposed sensitive information of about 147 million people, highlighting the importance of a swift and effective response strategy. Similarly, the 2020 SolarWinds cyberattack demonstrated how critical it is to detect and respond to vulnerabilities promptly to prevent widespread damage. A well-prepared incident response plan can significantly mitigate risks and help organizations maintain trust with their customers.
Examples
- The 2017 Equifax data breach, where sensitive information was exposed.
- The 2020 SolarWinds cyberattack, which compromised numerous government and private sector organizations.
Additional Information
- An effective incident response plan includes regular training and simulations for the incident response team.
- Post-incident reviews help organizations learn from incidents and improve their security posture.
