Containment involves isolating affected systems, networks, or devices to prevent the incident from escalating or causing further damage. This can include disconnecting the system from the network, disabling certain services, or implementing access controls. Eradication entails removing the cause of the incident, such as eliminating malware or closing vulnerabilities that were exploited. Once the threat has been neutralized and the systems have been secured, the recovery phase occurs, which consists of returning affected systems to operation and restoring lost or compromised data. This phase might also involve implementing additional safeguards to prevent similar incidents from occurring in the future and conducting a post-incident analysis to learn from the incident and improve the response process.
Guide on Incident Containment, Eradication, and Recovery
Incident Containment, Eradication, and Recovery forms a crucial part of the CompTIA Security+ certification exam, as it tests your understanding of key incident response procedures within cybersecurity.
What it is: This concept refers to the procedure in which an organization responds to, controls, eliminates and restores operations after a security breach or an incident.
Why it's important: It's essential to be familiar with this process as it minimizes the damage of an incident, removes the threat from the environment, and restores normal operations safely. Without these skills, an organization can suffer significant damages.
How it works: Incident response involves 4 key stages: 1. Containment stops the incident from causing further damage. 2. Eradication involves removing the cause of the incident. 3. Recovery involves restoring systems and operations to normal. 4. Lessons learned involves implementing changes based on the incident to prevent future occurrences.
Exam Tips: To answer questions in the exam, focus on understanding the methodologies involved in each step, and why they are crucial. Questions will likely test your understanding about when to implement each step, and how they are performed. Be aware of common pitfalls and best practices to gain the maximum possible points. Remember, the goal is not only to eliminate the threat but to recover operations safely while preventing future incidents.
