๐ณWhat is Incident Response
Incident response is a structured approach to handling and managing security incidents, breaches, and cyber threats. It aims to identify, contain, and mitigate the impact of security incidents to minimize damage, recover from incidents, and prevent future occurrences. Here are the key phases of incident response:
Preparation: Establishing and maintaining an incident response capability, which includes creating an incident response plan, defining roles and responsibilities, and conducting regular training and awareness programs.
Identification: Detecting and determining whether an incident has occurred. This involves monitoring systems, analyzing alerts, and gathering information to identify signs of an incident.
Containment: Limiting the scope and impact of the incident. Short-term containment might involve isolating affected systems, while long-term containment focuses on more comprehensive measures to prevent the incident from spreading.
Eradication: Removing the cause of the incident, such as deleting malware, closing vulnerabilities, and eliminating the threat from the environment.
Recovery: Restoring and validating system functionality. This includes restoring systems from backups, patching vulnerabilities, and ensuring that systems are secure and operational.
Lessons Learned: Analyzing the incident to understand what happened, why it happened, and how it was handled. This phase involves documenting findings, improving the incident response plan, and implementing measures to prevent similar incidents in the future.
