What is STAR Security, Trust & Assurance Registry (CSA)

STAR Security, Trust & Assurance Registry (CSA) Explained Technically

The Cloud Security Alliance (CSA) Security, Trust & Assurance Registry (STAR) is a program designed to provide a public registry of cloud service providers (CSPs) that have undergone independent security assessments. This registry serves as a valuable tool for users to evaluate the security posture of potential cloud providers.

Here's a breakdown of the key technical details of the CSA STAR program and its registry:

Purpose of the STAR Registry:

• Transparency and Trust: The registry aims to increase transparency in the cloud computing industry by allowing CSPs to showcase their security and compliance efforts.
• Risk Assessment for Users: Users can leverage the registry to assess the security posture of different cloud providers, facilitating informed decision-making when selecting a service.
• Standardization and Harmonization: STAR promotes the adoption of standardized security controls outlined in the Cloud Controls Matrix (CCM), helping to harmonize security practices across different cloud offerings.

Components of the STAR Program:

• Self-Assessment (Level 1): At the most basic level, CSPs can complete a self-assessment questionnaire based on the CCM. This self-assessment is not an independent verification but allows CSPs to document their adherence to security best practices.
• Third-Party Audit (Level 2): For a more rigorous assessment, CSPs can engage an independent third-party auditor to verify their compliance with the CCM. The results are submitted to the CSA for inclusion in the registry.
• Continuous Monitoring (Level 3): This highest level involves ongoing monitoring of the CSP's security controls by an independent auditor. The registry displays the specific level of assurance attained by each listed CSP.

Benefits of Participating in the STAR Registry (for CSPs):

• Demonstrated Security Commitment: Inclusion in the registry allows CSPs to showcase their commitment to security and build trust with potential customers.
• Competitive Advantage: A strong security posture highlighted in the registry can provide a competitive edge in a crowded market.
• Reduced Customer Audits: Customers who rely on the STAR registry might be less likely to conduct their own time-consuming security audits.

Benefits of Using the STAR Registry (for Users):

• Simplified Cloud Security Assessment: The registry simplifies the process of evaluating the security posture of potential cloud providers.
• Reduced Risk: By selecting a CSP with a good security record demonstrated in the registry, users can mitigate risks associated with cloud adoption.
• Benchmarking: The registry allows users to compare security practices across different cloud providers and identify those who best align with their specific security requirements.

Accessing the STAR Registry:

The STAR Registry is publicly accessible on the CSA website: https://cloudsecurityalliance.org/star/registry

Understanding the STAR Registry is important for:

• Cloud Service Providers: To demonstrate their commitment to security and gain a competitive advantage.
• Cloud Users: To make informed decisions when selecting a cloud provider based on transparency and documented security practices.
• Security Professionals: To keep up-to-date with the evolving security landscape of cloud computing services.

The CSA STAR program and its registry contribute significantly to enhancing transparency and security in the cloud computing industry. By utilizing the registry, both cloud providers and users can benefit from a more secure and trustworthy cloud environment.
