Securing Storage Networks

Written by  Greg Schulz & David O'Leary

As storage networks grow larger and become more pervasive, IT managers face two challenges: balancing security needs to protect critical information resources and maintaining the flexibility necessary to meet growth scalability and changing business requirements. Increasing pressure within business verticals for regulatory compliance plays into the security landscape, and manifests itself with requirements for online data retention and secured storage of data elements. This paper provides an understanding of various storage networking security threats and how to protect against them. Introduction Storage area networks (SANs) provide a mechanism by which information can be efficiently accessed and managed to support evolving business solutions. With SANs, storage devices that were previously attached to servers using secure dedicated interfaces can now be shared across multiple servers. Ultimately, this effective utilization and management of information and resources can reduce total cost of ownership (TCO) and return on investment (ROI). Traditionally, security for storage and storage interfaces
