Cyber Incident Response is a set of procedures and processes designed to help an organization respond to and manage a cyber incident effectively. A cyber incident is any event that compromises the confidentiality, integrity, or availability of an organization's information systems or data. Cyber Incident Response is crucial for minimizing the impact of cyberattacks and ensuring business continuity.
This stage involves developing an incident response plan (IRP) that outlines the roles, responsibilities, and procedures for responding to cyber incidents. It also includes conducting regular training and drills to ensure that staff are prepared to respond effectively.
In this stage, organizations detect and identify potential cyber incidents by monitoring their networks and systems for unusual activity or security breaches. This may involve using intrusion detection systems (IDS), security information and event management (SIEM) tools, and other monitoring tools.
Once a cyber incident is identified, the next step is to contain it to prevent further damage. This may involve isolating affected systems, disabling compromised accounts, and implementing temporary fixes to stop the attack.
After containing the incident, organizations work to eradicate the root cause of the incident. This may involve removing malware, patching vulnerabilities, and implementing security measures to prevent similar incidents in the future.
Once the incident is contained and eradicated, organizations focus on restoring affected systems and data to normal operations. This may involve restoring data from backups, rebuilding systems, and implementing additional security measures.
After the incident is resolved, organizations conduct a post-incident review to identify lessons learned and improve their incident response process. This may involve updating the incident response plan, implementing new security measures, and providing additional training to staff.
