When it comes to cyber security incidents, it’s important to have a well-defined and effective response plan in place. Such a plan should include various types of plans, such as incident response planning, business continuity planning, disaster recovery planning, and crisis management planning. These plans work together to provide a comprehensive approach to handling a cyber attack.
One of the first steps in building a cyber attack response plan is to carry out a threat modeling exercise. This exercise helps identify the threats that exist, the assets they could threaten, and the capabilities the organization has to mitigate those threats. It also provides an opportunity to improve security by implementing countermeasures.
Once the threats have been identified, the next step is to decide on the roles and responsibilities within the response plan. It’s important to have clear and unambiguous roles, with backups identified for critical roles. The responsibilities and authorities of each role should also be clearly defined, including who can call an incident, activate the business continuity plan, authorize external or internal communications, and liaise with authorities or regulators.
With the roles and responsibilities in place, the next step is to build the cyber attack response plan. This plan should outline the steps to be taken in the event of an incident, including investigation, containment, recovery, and lessons learned. It should be based on the threats and assets identified in the threat modeling exercise and should provide clear guidance for the organization to follow.
Testing and learning from incidents is a vital step in building an effective cyber attack response plan. After an incident, it’s important to review what was done well and what could be improved. This can be done through tabletop scenario exercises or by bringing in third parties to provide a different perspective. By running through hypothetical attacks, organizations can identify any gaps in their plans and make necessary improvements.
Overall, having an effective cyber attack response plan is crucial for organizations to minimize the impact of an incident. By following the steps outlined above and continuously reviewing and improving the plan, organizations can better protect themselves from cyber attacks.
