Securing Your Data in a Multi-Cloud World: Best Practices

Organizations have transitioned from using a single cloud provider to employing multiple ones simultaneously. This has various advantages, including avoiding vendor lock-in, reducing reliance on a vendor, and creating a strong data system by leveraging the strength of each vendor.

Despite the benefits of a multi-cloud world, it brings various concerns, one of which is data insecurity. Using various cloud providers can lead to data disasters if not carefully managed. Fortunately, following the proper procedures might help to secure your data in a multi-cloud environment. This article covers ten best practices for securing data in a multi-cloud context.

What is a Multi-cloud Environment?

A multi-cloud environment is a strategy where organizations use multiple cloud computing services from different vendors within a single architecture. Using this strategy helps companies divide their tasks across many cloud services. Still, one system controls all of them.

A multi-cloud environment helps businesses to improve resilience by distributing the work across various cloud providers, using each vendor’s strengths and unique characteristics, and selecting specific services that meet their needs. It also lessens vendor lock-in risk, helps against total failure or outage, and lessens over-dependence on one supplier.

Unlike a hybrid cloud architecture—which combines cloud services with on-site resources for maximum efficiency—a multi-cloud environment works separately. While hybrid uses both worlds, multi-cloud makes use of many cloud providers.

10 Best Practices to Secure Your Data in a Multi-Cloud Environment

1. Enable Data and Application Portability

Data and application portability has become a major challenge for organizations in the multi-cloud environment. This challenge is a result of silos being created. Cloud providers have proprietary APIs and data management tools. Hence, it becomes difficult to share or move data between clouds, leading to information getting trapped within the cloud it was generated in, which then creates data silos. One way to solve this is by adopting cross-cloud data-sharing technologies. These technologies support high-bandwidth connections between public clouds and give way to actual data sharing.

2. Aggregate and Centralize Data in the Cloud

Organizations process a wide range of data daily, leading to data fragmentation, where valuable data is scattered across multiple platforms. This fragmentation complicates data analysis and can lead to lost insights. However, organizations can address this issue by centralizing their data in a single database, data lake, or cloud data platform and managing data from a single dashboard. Collecting and managing data centrally supports comprehensive data analysis and data-driven decision-making by providing a complete view of all relevant data. Amazon S3, Google Cloud Storage, and similar platforms are durable and scalable storage solutions that can consolidate data from various sources.

3. Standardize Security Practices Across Cloud Providers

Organizations operating in a Multi-cloud environment are susceptible to cyber-attacks. That’s why standardization is critical in security practices across all cloud providers. Organizations must implement a unified security standard within cloud environments, making managing security across different platforms easier. This will lower the chance of being breached and simplify security management across multiple platforms. Centralizing security data into a single repository, like a security data lake, can provide continuous visibility and enable comprehensive monitoring of your entire multi-cloud environment from one interface.

4. Implement Multi-Cloud Disaster Recovery

Disaster recovery is a crucial part of any robust cloud strategy because it prevents data loss in the event of a disaster. Hence, it’s essential to conduct constant backup and implement a fail-proof disaster recovery plan to protect against the effects of the disaster.

Most cloud providers offer disaster recovery. However, relying on only one provider can lead to further problems during an outage. So, it’s better to implement a multi-cloud disaster recovery strategy that is robust enough to protect your diverse cloud systems. This strategy allows you to restore data and apps from one cloud to another should there be an outage. It also improves resilience and leverages the strengths of several cloud providers to provide continuity and reduce data loss after a disaster.

5. Strategic Multi-Cloud Storage

Organizations must be smart about data storage to ensure successful data security. This includes classifying data based on sensitivity and ensuring that sensitive information is stored in the most secure environments. To achieve low latency and regulatory compliance, organizations also need to think about how they disseminate data across geographical areas. Integrating data loss prevention (DLP) technology can also ensure data security and compliance. DLP technology can assist in detecting and preventing data loss or exfiltration across several cloud environments.

6. Automate Security Processes

Automation is crucial in large settings, including multi-cloud environments. Automation ensures that the security process is robust, smooth, and secure. They help accomplish routine tasks like scanning new virtual machines or containers for vulnerabilities, without the need for human intervention. At a higher level, they become essential for reducing human errors and ensuring uniform application of security policies across cloud environments.

7. Consolidated Monitoring

Effective security monitoring becomes critical in a multi-cloud setup, with the platforms offering differing levels of visibility and control. Organizations should design an integrated approach to monitoring that focuses on aggregating logs, alerts, and events from all cloud providers into one system. This will support the ability to detect and react effectively to any potential security incident, ensuring fast remediation with minimal impact of breaches.

8. Optimize Data Retention for Compliance and Analytics

Data retention policies are critical for ensuring compliance and operational effectiveness in a multi-cloud scenario. Organizations should build an inventory of all data generated or collected, assess retention needs based on legal and regulatory standards, and identify data required for operational procedures. Implementing thorough data retention policies allows an organization to ensure that crucial data is securely maintained for the right time, supporting compliance and analytics use cases.

9. Maintain Compliance Across Multiple Clouds

Organizations must comply with regulatory regulations relevant to their industry. However, cloud companies give varying compliance certifications and standards. As a result, enterprises must rely on automated tools to ensure compliance in a multi-cloud environment. These solutions continuously track compliance across all clouds to make sure that your cloud infrastructure complies with all applicable regulations. Thus, you can lower the risk of attracting legal and financial penalties.

10. Implement a Zero-Trust Security Model

In a multi-cloud context, implementing a zero-trust security strategy is critical. This technique ensures that only authorized users can access certain data and apps, reducing the risk of illegal access and data breaches. Organizations should adopt strict access controls, multi-factor authentication, and continuous monitoring to apply zero-trust concepts to all cloud settings.
