Most businesses have started moving their services to the cloud in the last few years. As a result, the focus of cyber attackers has also shifted towards cloud infrastructure. They are coming up with more sophisticated techniques and methods that are specifically designed to compromise cloud infrastructure. Thus, it becomes imperative for businesses to have a cloud incident response team that understands the risks associated with the cloud.
In this article, we will discuss the basics of cloud incident response along with the best practices to build a cloud incident response plan.
Cloud Incident Response Overview
An incident is an unexpected interruption in IT services. In a fast-paced business environment, where downtime can be very costly, businesses must invest in a strong incident response methodology.
Having said that, because incidents affect the performance of the overall business and result in downtime, it is imperative that the cybersecurity incident response team respond to problems quickly and accurately. But traditional IT systems are just not capable of addressing incident security quickly.
On the other hand, DevOps relies on collaboration, speed, and transparency for seamless deployment, so cloud incident response makes it possible for the incident response team to tackle threats, allowing for efficient incident response procedures by bringing all these functions in one place. Therefore, cloud incident response teams are much more capable of tracking processes, collaborating, and automating key security tasks.
Best Practices to Build an Incident Response Plan
The following are the best practices to follow for building an incident response plan for your organization.
- Have a Process in Place
No one can predict every other type of incident that the organization might encounter in the future. But one can keep themselves prepared for all types of incidents. Therefore, make sure you have a process in place for responding to incidents as and when they occur.
This will help the incident response team to resolve incidents faster, reduce revenue losses, improve internal and external communication, and promote continuous improvement. Moreover, having a response plan ensures that the team is ready to address incidents more confidently and quickly.
- Assess Impact and Prioritize Risks
It is imperative to make a quick decision when you detect any incident. You should also be able to assess the impact very quickly and prioritize risks.
Ensure that you have a clear line of communication with your team members and each one of them is aware of their responsibility during the crisis. Once you have prioritized the risks, make sure you take the necessary actions.
- Invest in the Right Tools
Cloud infrastructure is complex and large; it consists of many parts to monitor and track. Therefore, it is crucial to invest in the right tools to help support your incident management.
Use these tools to automate tasks wherever possible. It can include anything that is repetitive and takes up your valuable time unnecessarily. You can use automation to remove additional noise and thus help everyone to focus on the more important tasks at hand.
- Use Diagrams
Cloud infrastructure is complex. Therefore, security incidents can often go undetected as teams are working in silos, making it difficult to identify top priority issues.
By using diagrams and mapping the cloud architecture, you are keeping everyone on the same page, thus ensuring that the incident is not going undetected. It also makes it easy to share recommendations with shareholders.
Communication is key when it comes to an effective incident response plan. Therefore, communicate as much as possible. Every individual in the incident response team must know his/her duties and responsibilities in case of any security incident.
If you are to communicate with a large group, you can even create a status page for tracking updates on the incident. With so many moving parts, communication is something that can help resolve the security incident as quickly as possible.
Get Certified as an Incident Handler
The best way to develop an in-depth understanding of cloud incident response and associated incident handling processes is by taking on a certification for you or your team. Consider EC-Council’s Certified Incident Handler (ECIH) program, which has been developed in collaboration with cybersecurity and incident handling response practitioners across the globe. The incident handler certification provides a structured approach to learning real-world incident handling and response requirements.
