5.26 Response to IS Incidents

Information security incidents should be responded to in accordance with the documented procedures.

Response to information security incidents typically involves a set of procedures and actions that organisations take to address and mitigate the impact of a security breach or attack.

Implementing a response to information security incidents typically involves several steps:

• Develop an incident response plan: The organisation should have a formal incident response plan in place that outlines the procedures and roles for responding to different types of incidents. This plan should be reviewed and tested to ensure that it is up-to-date and effective.
• Train staff: All employees should be trained on the incident response plan and their roles in responding to incidents. Regular training and drills can help staff prepare to respond quickly and effectively.
• Establish incident response teams: Organizations should have dedicated incident response teams in place, consisting of individuals with the necessary technical and organizational skills to respond to incidents.
• Identify and prioritize assets: Organizations should identify and prioritize the assets that are most critical to their operations so that they can be better protected and quickly restored in the event of an incident.
• Implement monitoring and detection: Organizations should implement monitoring and detection mechanisms, such as intrusion detection systems, to detect potential incidents as quickly as possible.
• Establish incident response procedures: Organizations should establish procedures for responding to different types of incidents, such as data breaches, network intrusions, and Denial of Service attacks.
• Communicate with stakeholders: Organizations should establish clear communication procedures with stakeholders, such as customers and partners, to keep them informed of incidents and the actions being taken to address them.
• Review and improve: Finally, organizations should regularly review and improve their incident response processes, using lessons learned from past incidents to improve their overall security posture.
