Chapter 14: Security, Isolation, and Policy Enforcement

Secure your search stack with multi-tenant isolation, access control, encryption, and zero-trust design.

Chapter Overview​

Search systems often contain sensitive data and must enforce strict access controls. This chapter covers the security models that protect search infrastructure, from role-based access control to zero-trust architectures.

Implementing proper security is non-negotiable for enterprise search deployments.

14.1 Access Control Models​

14.1.1 Index-level ACLs

14.1.2 Role-based access control (RBAC)

14.1.3 Attribute-based access control (ABAC)

14.2 Tenant Isolation​

14.2.1 Namespace partitioning

14.2.2 Resource quotas and limits

14.2.3 Isolation in multi-cloud environments

14.3 Secure Ingestion and Zero Trust​

14.3.1 AuthN and AuthZ at ingest

14.3.2 Encrypted pipelines and bring-your-own-key (BYOK)

14.3.3 Zero-trust deployment models

Examples​

Examples coming soon.

Code examples for this chapter will demonstrate access control configuration, tenant isolation, and secure ingestion patterns with Lucenia.
