Managing security across multiple cloud environments is challenging. With cloud usage increasing, ensuring that your sensitive data is safe from risks caused by third-party vendors, often referred to as sub-processors, is critical. These sub-processors provide essential services, but their involvement introduces additional considerations for your security architecture.
This blog outlines what multi-cloud security sub-processors are, the risks they pose, and the strategies you can use to address them. By the end, you’ll have actionable steps to strengthen your multi-cloud security posture.
What Are Multi-Cloud Security Sub-Processors?
Sub-processors are third-party vendors that process data on behalf of your cloud service providers. For example, your cloud provider might rely on other companies for database management, logging services, or scalability tools. When you operate in a multi-cloud environment (using AWS, Azure, GCP, etc.), the network of sub-processors becomes more complex, which increases your exposure to potential weaknesses.
In simpler terms, sub-processors extend the technical backbone of your cloud infrastructure. However, their involvement introduces indirect risks that you, as a cloud customer, must monitor and manage carefully.
Key Risks of Sub-Processors in Multi-Cloud Security
While sub-processors enhance your cloud capabilities, they also expand your attack surface. Here are the major risks to consider:
1. Unclear Data Ownership
Sub-processors often interact with sensitive data, yet contractual boundaries around who owns and secures this data can be vague. Unclear accountability can lead to misunderstandings during audits or breaches.
2. Lack of Transparency
Many cloud providers do not disclose their full list of sub-processors or the extent of their involvement. Without full transparency, it’s hard to perform due diligence or evaluate risk accurately.
3. Security Gaps
Sub-processors might not meet your organization’s security standards or policies. Even when your primary cloud provider has robust practices, a sub-processor using outdated or vulnerable systems could expose your data.
4. Compliance Challenges
Regulations like GDPR and HIPAA require accountability for every entity handling personal or sensitive data. Identifying whether a sub-processor’s practices meet compliance is often complicated in distributed, multi-cloud setups.
5. Limited Monitoring & Control
Since sub-processors operate independently, gaining visibility into their activities can be difficult. This lack of monitoring reduces your ability to detect and respond to potential threats in real time.
Best Practices for Managing Multi-Cloud Sub-Processors
Fortunately, there are practical steps you can take to secure your systems against these risks:
1. Understand Your Cloud Providers' Sub-Processor Policies
Start by asking for a clear list of their sub-processors, including their functions and regions of operation. Study their security certifications (like ISO 27001 or SOC 2) to ensure alignment with your organization's policies.
2. Conduct Regular Risk Assessments
Evaluate the risks associated with each sub-processor using a structured process. Perform detailed audits that consider how data flows between your infrastructure and their systems.
3. Build Strong Contracts
Ensure contracts clearly define roles, responsibilities, and liabilities in case of security breaches. Push for clauses around data encryption and incident reporting timelines, even at the sub-processor level.
4. Automate Sub-Processor Monitoring
Utilize tools that provide continuous monitoring and logging of sub-processor activities. Automation makes it easier to uphold security standards with minimal manual intervention.
5. Keep a Focused Compliance Checklist
Maintain an updated compliance checklist that includes checks for sub-processors. This ensures you stay ahead of audits and avoid penalties for data mishandling.
A Smarter Way to Manage Multi-Cloud Security Risks
