This IBM Redbooks publication examines the advanced security capabilities introduced with IBM Power11, designed to meet the challenges of hybrid cloud environments and evolving cyber threats. Built on IBM’s Zero Trust framework, Power11 delivers a secure foundation for hybrid deployments while aligning with global compliance standards. Key enhancements include automated key lifecycle management, role-based access control (RBAC), firmware and OS hardening, and quantum-safe cryptography readiness, ensuring data integrity and resilience against emerging risks such as quantum computing. The platform’s architecture supports strong isolation and multi-tenancy, enabling secure execution of mission-critical workloads. Integration with IBM’s security portfolio—QRadar, Guardium, and Security Verify—adds layered defense, automated risk management, and compliance reporting. Power11 is immediately available in IBM Power Virtual Server (PowerVS) data centers, extending these capabilities to cloud environments with encryption, secure connectivity, and identity management. Additionally, IBM Power Cyber Vault offers cyber resiliency through isolated recovery environments and immutable data copies for rapid ransomware recovery. Together, Power11 and its ecosystem deliver a trusted, future-ready platform for secure hybrid cloud operations.
