    Abstract

    This IBM Redbooks® publication examines the advanced security capabilities that are introduced with IBM Power11, which are designed to meet the challenges of hybrid cloud environments and evolving cyberthreats. Built on the IBM® zero trust framework, Power11 delivers a secure foundation for hybrid deployments while it aligns with global compliance standards. Key enhancements include automated key lifecycle management, role-based access control (RBAC), firmware and operating system (OS) hardening, and quantum-safe cryptography readiness. These capabilities help ensure data integrity and resilience against emerging risks such as quantum computing.

    The platform architecture supports strong isolation and multitenancy, which enables secure running of mission-critical workloads. Integration with the IBM security portfolio

    (IBM QRadar®, IBM Guardium®, and IBM Security Verify) adds layered defense, automated risk management, and compliance reporting.

    Power11 is immediately available in IBM Power Virtual Server (PowerVS) data centers, and it extends these capabilities to cloud environments with encryption, secure connectivity, and identity management (IdM).

    In addition, 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.

    This book is intended for IT architects, security professionals, and enterprise administrators who need to design, deploy, and manage secure hybrid cloud environments by using the advanced security capabilities of Power11.
