What is Cloud Computing?
- Infrastructure as a Service (IaaS): infrastructure resources such as servers, storage, and networks are delivered as a service.
- Platform as a Service (PaaS): platform services such as operating systems, databases, and development frameworks are delivered as a service.
- Software as a Service (SaaS): applications are delivered as a service without the need for installation and maintenance.
Cloud computing offers many benefits such as automated backups, greater fault tolerance, and easier disaster recovery. However, it also comes with its own set of risks such as data breaches, cyber attacks, and data loss.
What is Data Governance?
- Data quality: ensuring that data is accurate, complete, and consistent.
- Data security: protecting data from unauthorized access, modification, and destruction.
- Data integration: integrating data from multiple sources to provide a single, unified view of the data.
- Data architecture: designing and managing data models, metadata, and data structures.
- Data tracing: tracking data lineage and data flow to ensure compliance and auditability.
- Data policy: defining data policies, standards, and guidelines to govern data usage.
Challenges and Risks of Cloud Computing
- Data breaches: unauthorized access to data can result in loss or theft of sensitive data.
- Cyber attacks: hackers can exploit vulnerabilities in cloud services to steal data or disrupt services.
- Data loss: technical glitches, hardware failures, or natural disasters can cause permanent data loss.
- Compliance violations: regulatory requirements such as GDPR, CCPA, HIPAA, or PCI DSS require specific data governance and security controls that must be enforced in the cloud.
- Shadow IT: employees can access cloud services without proper authorization or control, leading to security risks and compliance violations.
Ensuring Compliance and Data Security in the Cloud
1. Create a Cloud Governance Framework
Implement a cloud governance framework that outlines the policies, processes, and procedures for cloud usage across the organization. This framework should include the following:
- Cloud risk management: identify and assess the cloud service providers’ risks and adopt appropriate risk mitigation measures.
- Cloud service provider selection: define the criteria for selecting cloud service providers based on security, compliance, performance, cost, and support.
- Cloud service agreement negotiation: negotiate the cloud service agreements to include data security, privacy, regulatory compliance, and auditability requirements.
- Cloud service usage policies: establish policies for the proper use of cloud services, including access control, data classification, retention, and destruction.
- Cloud service monitoring and reporting: monitor and report on the usage, performance, and compliance of cloud services.
2. Conduct Regular Cloud Security Assessments
Perform regular security assessments to identify, assess, and mitigate security risks associated with cloud services. These assessments should include:
- Cloud risk assessment: identify security risks, threats, and vulnerabilities associated with the cloud infrastructure, applications, and data.
- Cloud penetration testing: test the cloud infrastructure and applications for security weaknesses, including network security, authorization, and authentication.
- Cloud log monitoring and analysis: continuously monitor logs from cloud services to detect suspicious activities and potential security breaches.
- Cloud compliance assessment: assess the compliance of cloud services with regulatory requirements such as GDPR, CCPA, and HIPAA.
3. Implement Cloud Access and Identity Management
Implement an access and identity management system to control and monitor access to cloud services. This should include:
- Single sign-on: a centralized authentication system that enables users to access multiple cloud services with a single set of credentials.
- Two-factor authentication: an additional security layer that requires users to provide two types of authentication such as a username/password and a token or biometric factor.
- Identity and access management: setting up roles, permissions, and access policies for different cloud services based on the user’s job function, responsibilities, and identity.
- Access monitoring and reporting: monitoring and reporting on user access and activities on cloud services to detect unauthorized access and comply with regulations.
4. Encrypt Data at Rest and in Transit
Encrypt data at rest and in transit to ensure that data is protected from unauthorized access and theft. This should include:
- Data encryption: encrypting data using industry-standard encryption algorithms such as AES to protect data at rest.
- Secure data transport: encrypt data in transit using SSL or TLS to protect data in transit.
- Key management: ensure that encryption keys are managed securely, including key generation, storage, retrieval, and destruction.
- Data backup and disaster recovery: backup data regularly to a secure location and implement disaster recovery procedures to ensure that data can be recovered in the event of an outage or disaster.
