Incident response
Incident response in cybersecurity refers to a process that includes planning, preparation, detection, investigation, analysis, containment, and subsequent response to security incidents. This process aims to minimize the negative consequences of cyber-attacks, data breaches and other incidents affecting the organization's information systems and networks.
The cybersecurity incident response process typically follows these steps: Planning:
Develop a written incident response plan that outlines the roles and responsibilities of incident response team members, incident detection and response procedures, and communication channels with key stakeholders.
Detection: Continuous monitoring of network infrastructure and systems for any signs of unusual activity, such as suspicious network traffic, unauthorized access, or unusual user behavior.
Investigation: Conducting a thorough investigation of identified incidents to determine the scope, cause and impact of the incident. This includes collecting and analyzing logs, event logs and other relevant information.
Analysis: Assessing the severity of the incident and the potential impact on the organization, including assessing the risk associated with the incident and determining appropriate mitigation actions.
Containment: Temporarily isolating infected systems or networks from the rest of the infrastructure to prevent further damage and preserve evidence for the investigation.
Subsequent response: Restoring normal operations, eliminating the causes of the incident, and implementing corrective actions to prevent similar incidents from occurring again. This may include updating systems and software, implementing additional security measures, and conducting follow-up training for employees.
Learning and improvement: Regularly reviewing and updating incident response plans based on lessons learned from past incidents and conducting simulations to learn and improve the organization's ability to respond effectively to security incidents.
