especially in a multi-tenant cloud environment.

When managing cloud encryption, organizations face a crucial choice: provider-managed encryption, which simplifies usage but offers less control, and customer-managed encryption, which allows greater control but comes with a higher operational burden. Moreover, data encrypted by one cloud provider presents certain security risks when it needs to be decrypted for use by another provider or on-premises systems, exposing the data during transit.

Evaluating cloud providers for data privacy

Given the cloud data privacy challenges, it becomes paramount to carefully evaluate cloud providers. Providers should be evaluated on their adherence to common security standards and protocols such as ISO 27001:2013, ISO-27002, ISO-27017, and ISO-27018, along with compliance to regulations like PCI DSS, NIST SP 800 Series, FedRAMP, CCPA, HIPAA, and GDPR for EU customers.

It is important to evaluate a cloud provider’s data privacy measures, including their cloud data security capabilities. This encompasses assessing their abilities in authentication, access control, encryption, and intrusion detection systems.

Service Level Agreements (SLAs) are critical documents that define the following between a cloud service provider and their customer:

• Security considerations
• Governance
• Maintenance
• Support

SLAs ensure accountability and risk minimization.

Vendor selection and due diligence

Evaluating a cloud provider’s history of breaches and performance history reveals their security track record, which is vital for making informed vendor selection decisions. Organizations should assess a cloud vendor’s security measures, breach response plans, and understand their security policies and procedures as part of the selection process.

The locations of a cloud service provider’s data storage are crucial considerations for security, confidentiality, resiliency, and recovery needs. The quality of a provider’s migration services can significantly impact the security and cost-effectiveness of the transition to cloud computing. In addition, an effective exit strategy is essential for maintaining flexibility and avoiding the pitfalls of vendor lock-in.
