Data Protection
Cloud providers are responsible for protecting customer data from unauthorized access, use, or disclosure, as well as from accidental loss or destruction.
Customers are responsible for ensuring that their data is encrypted and that appropriate access controls are in place to protect it from unauthorized access.
Compliance
Cloud providers are responsible for ensuring that their cloud platforms and services comply with relevant laws and regulations.
Customers are responsible for ensuring that their use of the cloud platform and services complies with applicable laws and regulations, as well as with the cloud provider’s terms of service.
Cloud Architecture Design Principles for Compliance
Compliant cloud architecture is designed following fundamental principles that ensure adherence to regulatory requirements and industry standards. These principles encompass security measures, data management, and operational controls to protect sensitive information and maintain regulatory compliance.
Data Segregation
Data segregation involves logically or physically separating data based on sensitivity, classification, or regulatory requirements. This principle minimizes the risk of unauthorized access or data breaches by restricting access to specific individuals or systems.
Access Control
Access control mechanisms define who can access data, systems, and resources in the cloud environment. These mechanisms include authentication, authorization, and role-based access control (RBAC) to ensure that only authorized users have access to the appropriate resources.
Encryption
Encryption is a critical principle for protecting data confidentiality. Data should be encrypted at rest and in transit to prevent unauthorized access or interception. Encryption keys should be securely managed and rotated regularly to maintain the integrity and confidentiality of sensitive data.
Logging and Monitoring
Logging and monitoring systems are essential for detecting and responding to security incidents. These systems collect and analyze logs, events, and metrics from cloud resources to identify potential threats, suspicious activities, and compliance violations.
Incident Response
An incident response plan Artikels the steps to be taken in the event of a security incident. This plan includes procedures for identifying, containing, eradicating, and recovering from security breaches or compliance violations. Regular testing and updating of the incident response plan are crucial to ensure its effectiveness.
