Orchestration security involves a combination of access control, encryption, and monitoring measures
Properly securing orchestration helps maintain the integrity and confidentiality of infrastructure and applications
Securing orchestration templates
Orchestration templates should be treated as sensitive artifacts and protected accordingly
Access to templates should be restricted based on the principle of least privilege, granting access only to authorized users and roles
Templates should be stored in secure, version-controlled repositories with appropriate access controls
Sensitive information (credentials, keys) should not be hardcoded in templates but instead passed as parameters or retrieved from secure secrets management systems
Templates should be regularly reviewed and updated to ensure they adhere to security best practices and standards
Orchestration role-based access control
Role-based access control (RBAC) is a mechanism for granting or restricting access to resources based on user roles and permissions
Orchestration platforms typically integrate with the cloud provider's RBAC system (IAM for AWS, Azure RBAC for Azure)
Users and roles should be granted the minimum permissions necessary to perform their tasks, following the principle of least privilege
Permissions should be regularly reviewed and updated to ensure they align with the current roles and responsibilities
Implementing proper RBAC helps prevent unauthorized access and modifications to orchestration resources and templates
Orchestration and compliance
Compliance requirements (HIPAA, PCI-DSS, GDPR) often have specific controls and guidelines for managing and securing infrastructure
Orchestration templates can be used to codify and enforce compliance requirements across different environments and projects
By defining compliant configurations in templates, teams can ensure that resources are consistently provisioned in accordance with the relevant regulations
Orchestration platforms may offer built-in compliance features or integrations with third-party compliance tools
Regular audits and assessments should be conducted to ensure that orchestration processes and templates remain compliant with the applicable standards and regulations
