IBM Systems Magazine, Mainframe - May/June 2017 - 30
target administrators to steal their credentials. IBM's blockchain cloud offering, the IBM Blockchain High Security Business Network (HSBN) plan, is exclusively The Future of Mainframe Optimization Wednesday, May 17 | 10 PT / Noon CT / 1 ET Key Considerations for Efficiency and Cost Management We'll discuss the key mainframe optimization problems, opportunities and use cases spanning DB2 and network management on z/OS, as well as new ways to save on your MLC. You'll also learn: /ÁHow the latest innovations for zIIP and sort will save you time and money /ÁHow workload-centric database optimization changes the game for DB2 and IDMS /ÁNew options for long-standing network management and IMS cost and resource issues FEATURING: John Reda Vice President, Software Engineering Syncsort Steve Menges Director, Product Management Syncsort Register Today: webcasts.com/ibmsystemsmag sponsored advertising content 30 // MAY/JUNE 2017 ibmsystemsmag.com hosted on IBM LinuxONE* servers because they have a unique capability to run blockchain networks as "black box" appliances. The technology, called the IBM Secure Service Container, enables an execution environment that utilizes advanced virtualization, encryption and hashing to prevent system admin access. Once the appliance image is built, OS access into the appliance isn't possible. Within the appliance, memory access is disabled and all disk associated with the image is encrypted- even debug data. Root users and system administrators are unable to access blockchain contents, adjust chain code or install malware when the blockchain network is installed in a Secure Service Container. IBM's z Systems* and LinuxONE servers already offer hardware virtualization certified to the highest commercially available international standards: Evaluation Assurance Level 5. The added protections provided by Secure Service Container deliver a level of security that goes beyond this and any other current standard. The z Systems and LinuxONE protections against abuse extend to encryption keys as well, as critical keys are protected by a tamper-responsive hardware security module certified to FIPS 140-2 Level 4; again, the highest commercially available level. Digital Vault It's expected that blockchain networks, built on private distributed ledger technologies, will concentrate high degrees of wealth-making them ideal targets for attack. To combat this, IBM early adopter Everledger is using the HSBN
