IBM Spectrum Scale Security

A draft IBM Redpaper publication

Abstract

Storage systems must provide reliable and convenient data access to all authorized users, while simultaneously preventing threats coming from outside or even inside the enterprise.

Security threats come in many forms, from unauthorized access to data, data tampering, denial of service, and obtaining privileged access to systems.

According to the Storage Network Industry Association (SNIA), data security in the context of storage systems is responsible for safeguarding the data against theft, prevention of unauthorized disclosure of data, prevention of data tampering and accidental corruption. This process ensures accountability, authenticity, business continuity, and regulatory compliance.

Security for storage systems can be classified as:


  • Data storage (Data at rest, which includes data durability and immutability)
  • Access to data
  • Movement of data (Data in flight)
  • Management of data
  • IBM® Spectrum Scale is a software-defined storage system for high performance, large-scale workloads on-premises or in the cloud.


      Spectrum Scale addresses all four aspects of security by securing data at rest, protecting data at rest with snapshots, backups and immutability features, securing data in flight, providing secure management of data, and secure access to data by using authentication and authorization across multiple supported access protocols. These protocols include POSIX, NFS, SMB, Hadoop, and Object (REST). For automated data management it is equipped with powerful information lifecycle management (ILM) tools that can help administer unstructured data providing the right security for the right data.

      This paper details the various aspects of security in Spectrum Scale, including


      • Security of data in transit
      • Security of data at rest
      • Authentication
      • Authorization
      • Hadoop security
      • Immutability
      • Secure administration
      • Audit Logging
      • Security for transparent cloud tiering
      • Security for OpenStack drivers
      • Unless stated otherwise, the functions that are mentioned in this paper are available in Spectrum Scale V4.2.1 or later releases.
