How do you align incident response with cloud governance?

由人工智能和领英社区提供技术支持

Cloud governance is the set of policies, processes, and tools that help you manage and secure your cloud resources. Incident response is the process of detecting, containing, analyzing, and resolving security incidents that affect your cloud environment. How do you align incident response with cloud governance? In this article, you will learn some best practices and tips to achieve this alignment and improve your cloud security posture.

1 Assess your cloud risks

Before you can design an effective incident response plan, you need to understand the potential threats and vulnerabilities that your cloud resources face. You can use various methods and frameworks to assess your cloud risks, such as the Cloud Security Alliance (CSA) Cloud Controls Matrix, the NIST Cybersecurity Framework, or the CIS Benchmarks. These tools can help you identify the gaps and weaknesses in your cloud security controls, as well as the impact and likelihood of different types of incidents.

To support your cloud incident response process, you need to implement the appropriate tools and technologies that can help you detect, analyze, and respond to cloud incidents. These tools should integrate with your cloud governance framework and provide visibility, automation, and orchestration capabilities.

In order to understand risks you have to study each and every cloud environment separately. Indigenously built applications have to be studied in details for their impact on overall clod security and incident response.

Employing frameworks like the Cloud Security Alliance's Cloud Controls Matrix, NIST Cybersecurity Framework, or CIS Benchmarks can illuminate gaps in cloud security controls and assess risk impact and likelihood. These tools provide a structured approach to identifying weaknesses and understanding potential threats, enabling you to design a response plan that is both targeted and robust. This proactive assessment lays a solid foundation for a response plan that effectively addresses the complexities of cloud security.

2 Define your cloud roles and responsibilities

One of the challenges of cloud governance is clarifying the roles and responsibilities of different stakeholders in your organization and your cloud service provider (CSP). You need to establish who is accountable and who is responsible for each aspect of cloud security and incident response. For example, you can use the shared responsibility model to define the division of duties between you and your CSP. You can also use the RACI matrix to assign the roles of Responsible, Accountable, Consulted, and Informed for each cloud security task and incident response activity.

Utilizing the shared responsibility model can help delineate security duties, specifying which tasks fall under your purview versus those of the CSP. Additionally, employing a RACI matrix (Responsible, Accountable, Consulted, Informed) for cloud security and incident response tasks ensures that everyone knows their roles and obligations. This structured approach not only streamlines accountability but also enhances collaboration, ensuring comprehensive and effective cloud security management.

3 Establish your cloud incident response process

Once you have assessed your cloud risks and defined your cloud roles and responsibilities, you can establish your cloud incident response process. This process should align with your cloud governance objectives and policies, as well as your business goals and requirements. You can use the NIST SP 800-61 or the SANS Incident Response Process as a reference to design your own process. Your process should include the following steps: preparation, identification, containment, eradication, recovery, and lessons learned.

Utilize frameworks like NIST SP 800-61 or SANS Incident Response Process to structure your approach. Your process should cover: preparation (readiness and training), identification (detecting and defining incidents), containment (limiting damage), eradication (removing threats), recovery (restoring operations), and lessons learned (analyzing and improving). This structured approach ensures a comprehensive response, reduces downtime, and enhances your overall cloud security posture.

4 Implement your cloud incident response tools

To support your cloud incident response process, you need to implement the appropriate tools and technologies that can help you detect, analyze, and respond to cloud incidents. These tools should integrate with your cloud governance framework and provide visibility, automation, and orchestration capabilities. Some of the tools that you can use are: cloud security monitoring and alerting tools, cloud log management and analysis tools, cloud forensics and malware analysis tools, and cloud incident response platforms.

5 Train your cloud incident response team

Your cloud incident response team is the group of people who will execute your cloud incident response process and use your cloud incident response tools. You need to train your team on the best practices and skills for cloud incident response, as well as the specific procedures and protocols for your organization and your CSP. You can use various methods and resources to train your team, such as online courses, certifications, workshops, simulations, and exercises.

6 Review and improve your cloud incident response plan

Your cloud incident response plan is the document that summarizes your cloud incident response process, tools, team, roles, responsibilities, and policies. You need to review and improve your plan regularly to ensure that it aligns with your cloud governance framework and reflects the changes and updates in your cloud environment and threat landscape. You can use various metrics and indicators to measure the effectiveness and efficiency of your plan, such as the mean time to detect, contain, and resolve incidents, the number and severity of incidents, and the customer satisfaction and feedback.

This article is too general to be of use. It needs to get into the complexities of securing your resources in a cloud and incident response as a shared responsibility between the CSP and your staff.
