What is a cybersecurity incident response plan (CSIRP)? If you do not have one yet, then you need to make one, ASAP. Why?
Ad what are the different stages of a CSIRP? Let us dig into that in this article.
Cybersecurity Incident Response Plan
We are living in a very modern world today. So, we rely a lot on digital technologies. And because of that, some threats and risks come with it.
So, how can your company fight against these? Yes, by having a CSIRP. If your company has one in place, then it can be prepared.
So, when incidents happen, it will serve as a guide for whatever steps are needed to do. Then, you can know what to do after the event. It will guide you on how to recover.
Stages of a Cybersecurity Incident Response Plan
First Stage: Preparation
Of course, the first one is the planning stage. You will first need to plan who is on your CSIRP team. Then, list out all their contact details and roles.
After, you will list out what kinds of situations will you need to contact them. Then, let them know of their roles. Then, plan on what you need to do in case of incidents.
Plan out for each scenario. Prepare for different risks. List out what you need to do during and after the incident. Then, drill your IRP team with every scenario.
Second: Detection and Analysis
The next stage is when attacks or breaches are currently happening. This is the stage when you have already detected one.
Yes, there is no way to be a hundred percent sure that you will be safe from attacks. So, you need to be able to detect an event fast.
Then, in this stage, documenting is crucial. It will help you analyze the problem later on. Then, during the incident, notify the important people. Like partners, law enforcement, and more.
Third Stage: Containment, Eradication, Recovery
The third stage will be the heart of your CSIRP. Why so? Because this will highlight how well you contain and eradicate the problem.
So, what was written on your CSIRP? You will need to be able to follow them. Then, your IRP team will need to follow the roles they are set to play once an event happens.
After removing the problem comes recovery. How will you get back on track after a breach? How will you continue your business?
Fourth Stage: Post-Incident Activities
Last, the post-incident activities. This is the next stage after you are back on business. Recovering from it is not enough.
So, you will need to:
- Reflect on the incident
- Assess how big the damage was
- Revisit your CSIRP and make changes as needed
- Start the notification process (to your customers, etc.)
Thus, the key part of the last stage is learning from the past incident. See where you went wrong and find ways to avoid it from happening again.
So, what are you waiting for? It is time to write that CSIRP to keep your company safe.
