What Are the Strategies That Can Be Used to Respond to Cyberattacks?
When an incident happens, time is crucial. The longer it takes to respond, the more likely the risks will increase. That’s why it is essential to have an incident response plan. By preparing yourself in advance, you can act quickly to identify and mitigate damage.
Here are five important activities for developing an effective incident response plan.
Understand Cybersecurity Incidents
What is crucial here is that organizations understand what is normal in their environment and what the potential risks are. If an organization does not know what a normal scenario looks like, how would it detect the abnormal or malicious one?
An information security risk assessment conducted annually or whenever you make significant changes to your organization will help you answer these questions as you analyze how your confidential information is used and how issues can arise.
Make Sure Your Scope Is Appropriate
The number of risks you identify will be incredibly huge, and realistically you won’t be able to deal with all of them.
You must therefore decide which risks to prioritize. Your decision should be based on an assessment of each threat’s potential damage and the likelihood of its occurrence.
Create An Incident Response Plan
With your most important threats identified, it is time to create an incident response plan to deal with them. This is a six-step process:
Preparation: The policies, procedures, governance, communication plans, and technology controls you will need to detect a security incident and continue operations once it occurs.
- Identification: Organizations need to be able to detect a potential incident. They must understand what information is available and in what location. Logs also need integrity. Can you trust that an attacker has not changed the logs?
- Containment: How you will isolate the problem and prevent it from causing further damage.
- Eradication: You should confirm what happened and answer any other questions the organization has.
- Recovery: The process of returning to business as usual.
- Lessons Learned: The processes of evaluating the implications of procedures and policies, collecting metrics, meeting reporting and compliance requirements, and identifying lessons that need to be learned.
Train Your Team
The success of your incident response plan depends on how well your team executes it. This includes not just the people responsible for creating and executing the plan, but everyone in your organization.
After all, their work can be interrupted when the plan goes into effect, so you need to make sure they are prepared. This means informing them of the plan, explaining why it is in place, and providing the necessary training to enable them to follow it.
Roles, responsibilities, dependencies, and authorization are also critical. Is the incident team empowered to make difficult and important decisions that could impact the organization’s operations?
