Table 1 Summary of Trust Mechanisms Impacting Cloud Computing

From: Building consumer trust in the cloud: an experimental analysis of the cloud trust label approach

Trust Mechanisms Example References
Website design The design, colours and aesthetics impact the perceptions of trustworthiness of online vendors. [42, 44, 45]
Feedback Reputation systems Comprehensive score reflecting an overall opinion or an aggregate of scores on several major aspects of performance. [19, 22, 23, 26, 52, 84]
Third Party Assurances Third party attestation, certification and/or assurances seals e.g. ISO/IEC 27001. [19, 22, 85]
Cloud transparency mechanism • Publicly accessible self-assessment of security controls e.g. Cloud Security Alliance (CSA) Security, Trust & Assurance Registry (STAR). [19, 22, 59]
• On-demand access to information on “elements of transparency” e.g. CSA CloudTrust Protocol. [19, 58, 59]
SLA-verification based trust Quality of service monitoring based on pre-defined SLA service levels. [19, 22, 23, 57]
Trust as a Service Single point service for configuring and managing security of cloud services from multiple service providers. [19, 60]
“Formal” trust mechanisms Trust based on “formal” certification and chains of trust for validation of attributes of a cloud service or its provider. [19, 61]
Trust Label Standardised label that presents a visual, real time summary of a range of relevant security and service information about a particular cloud to consumers in an easily understandable format. [16, 58, 73, 86]
