Safeguarding ASEAN’s Digital Future: Proactive Cloud Incident Response Strategies

The acceleration in the adoption of cloud technology has revolutionised the business landscape, and in doing so, significantly altered the cybersecurity ecosystem. The vast potential of cloud technology, such as its scalability, adaptability, and cost-effectiveness, has not gone unnoticed by nefarious entities seeking opportunities for exploitation. As businesses across ASEAN continue their transition to the cloud, they are increasingly confronted with escalating incidents of data breaches, ransomware attacks, and insider threats.

Therefore, it’s vital for organisations to devise and implement a robust cloud-specific incident response plan. Such a plan can help minimise the impact of security incidents, accelerate recovery time, and ensure optimal data protection in this rapidly evolving digital space.

Cloud Incident Response (IR) today needs to grapple with a radically different set of challenges, including data volume, accessibility, and the speed at which threats can multiply within cloud architectures. The interplay of various components, such as virtualization, storage, workloads, and cloud management software, intensifies the complexity of securing cloud environments.

That being said, Cloud IR cannot be done in isolation of the company’s overall incident response activities and business continuity plans. When possible, cloud security tools should use the same SOC, SOAR, and communication tools currently being used to secure other company elements. Using the same infrastructure ensures that suspicious and threatening cloud activities receive an immediate and appropriate response.

Creating an effective response plan involves understanding and managing the unique cloud platforms, being fully aware of data storage and access, and adeptly handling the dynamic nature of the cloud. Specifically:

Managing the Cloud Platform: The administrative console, the control centre of each cloud platform, facilitates the creation of new identities, service deployment, updates, and configurations impacting all cloud-hosted assets. This becomes an attractive target for threat actors, considering it offers direct access to the cloud infrastructure and user identities.

Understanding Data in the Cloud: The cloud hosts data, apps, and components on external servers, making it crucial to maintain correct configurations and timely updates. This is vital not just to prevent external threats, but also to manage internal vulnerabilities, such as misconfigurations, given the inherent complexity and size of cloud networks.

In conclusion, as businesses in the ASEAN region increasingly embrace cloud technologies, the need for a well-defined cloud IR plan has never been more crucial. By efficiently identifying signs of cloud-based threats, mitigating breaches, and limiting or eliminating damage, organisations can secure their cloud infrastructures, enhance their response processes, and reduce time to resolution.
