Delivering Ultimate SecurityWith today’s mobile users and complex supply chains as well as proliferation of social networks, data security is always under scrutiny. And with cloud and other new supply chain based

processing models it is difficult to have confidence about the custody and resiliency of your data. New computing models can raise the security and compliance risks enterprises face. z/OS and System z together form an ideal security hub for securing enterprise data and can offer security and privacy through various means such as secured authentication, audit, cryptography, and secured networking.

The z/OS Communications Server offers multiple tiers of network defense via Intrusion Prevention Services (IPS), and Intrusion Detection Services (IDS) as well as Application Transparent – Transport Layer Security (AT – TLS), IPSec, Network Security Services (NSS), Defensive Filtering and more. Furthermore, z/OS Communications Server offers you the ability to centrally manage your network settings—a great help in addressing audit and compliance issues.

The z/OS Security Server (RACF®) can help support security roles both on z/OS and those in distributed environments through integrated directories. Working together with IBM Tivoli® Directory Server (LDAP), RACF can provide enterprise wide authentication and audit capabilities applicable to z/OS and middleware workloads.

RACF also provides TCP/IP support for the RACF Remote Sharing Facility, Support hardware-generated Elliptic Curve Cryptography (ECC) secure keys and also can generate Elliptic Curve Cryptography secure keys using the Crypto Express Cryptographic Coprocessors for zEnterprise servers. The continued evolution of support for cryptography continues with z/OS V2.1 cryptography as a service, continued support for PKCS #11, and support for industry and government standards such as NIST NSA Suite B.

Data SheetSystem zIBM Systems and Technology

For cost effective public key infrastructure solutions, z/OS PKI Services can provide centralized digital certificate life cycle management within z/OS, taking out the cost of digital certificates managed by third-party vendors helping you to add this back to your bottom line. In addition, z/OS V2.1 offers additional planned enhancements such as:

●● ● The ability to offer remote crypto services to extend mainframe cryptographic services to Linux guests on the zBX or elsewhere.

●● ● Communications Server offers new security exits for the z/OS FTP client designed to help you achieve moresecured control of FTP file transfer activities

●● ● Communications Server is planned to support new cryptogra-phy suites implemented in TLS, and used by System SSL, in Application Transparent Transport Layer Security (AT-TLS) so new cipher suites can be used to encrypt traffic through a programmer-defined policy without requiring application changes

●● ● Communications Server enhancements to Intrusion Detection Services algorithms to reduce false positives

●● ● RACF database unload utility enhancements to unload additional information about digital certificates stored in RACF databases to help with audits.

●● ● Enhancements to z/OS UNIX System Services to specify whether a user should be logged off after a defined period of inactivity.

●● ● JES2 /JES3 support for access controls on job classes, to remove the need for similar user written exits.

●● ● New health checks on expiration of trusted certificates

CryptographyToday, z/OS offers a huge breadth of security capabilities built into the fabric of the operating system. Many z/OS security functions, such as data encryption, key management, PKI infrastructure, and password synchronization can be deployed to help harden the overall security level of your computing environment.

The cryptographic capabilities of System z are highly available and scalable and can take advantage of System z Parallel Sysplex and Geographically Dispersed Parallel Sysplex GDPS®. Enterprise Key management is also now much simpler on z/OS, with the new affiliated EKMF Solution offering IBM’s secured central key store along with new man-agement capabilities provides a compelling centralized key management solution compared to the use of distributed key stores on multiple Hardware Security Modules. For your most secured processing needs, encryption keys never appear within or leave System z in the clear.

Integrated Cryptographic Service Facility (ICSF) is the z/OS system software that serves as an interface with the crypto hardware. RACF key stores can handle certificates and keys; keys can be stored in either ICSF or RACF. The key store uses hardware crypto exploitation, regardless of whether keys are in stored in RACF or in ICSF.

RACF supports the generation of Elliptic Curve Cryptography and RSA secure keys using the Crypto Express4S in the new EP11 mode. The new Crypto Express4S EP11 configuration option is designed to meet public sector and European Union requirements where standardized crypto services and certifica-tions are needed. Corresponding PKCS #11 secure key support is planned for PKI Services for secure key operations. System SSL will also use certificates with secure PKCS #11 ECC and RSA certificates.

In z/OS V2.1, enhancements are planned for RACF Remote Sharing Facility (RRSF). For instance, in

z/OS V2.1 RACF, support is planned for RRSF connections over TCP/IP using IPv6, extending the existing IPV4 support. Also, RRSF uses Application Transparent Transport Layer Security (AT-TLS) to encrypt data between RRSF nodes using elliptic curve cryptography (ECC)-based certificates for stron-ger encryption algorithms.

Data SheetSystem zIBM Systems and Technology

Ciphersz/OS offers a broad set of encryption technologies, with support for Advanced Encryption Standard (AES), Data Encryption Standard (DES) and Triple DES, Secure Hashing Algorithms (SHA), Public Key Infrastructure (PKI), Elliptical Curve Cryptography (ECC), Galois/Counter Mode encryption for AES (GCM), Elliptic Curve Diffie-Hellman key derivation (ECDH), Elliptic Curve Digital Signature Algorithm (ECDSA), keyed-Hash Message Authentication Code (HMAC), RSA algorithms, and more. Also System SSL offers support for TLS V1.2 protocol and support for NSA Suite B Profile. z/OS encryption and key management technologies protects your communications and networks, as well as your data on IBM System Storage DS8000® and DS8700, DS8800 and IBM System Storage tape drives (TS1120, TS1130 and TS1140) and other storage devices, as well.

With z/OS V2.1, ITDS (LDAP) plans to comply with NIST SP 800-131a and NSA Suite B, adds support for SHA-256 and SHA-384 algorithms during SSL handshakes, and for AES-GCM ciphers, and also adds TLS V1.2 support.

Support for open standardsLike other operating systems, z/OS delivers support to enable application development and integration with existing invest-ments. Not only does z/OS support modern programming languages, and open standards, but z/OS also supports your existing code that typically runs the main processes of your business, offering you investment protection. A z/OS differenti-ation is that multiple programming environments can be sup-ported concurrently on the same hardware—all while meeting established service levels. Plus z/OS delivers performance and security benefits from running applications in close proximity to corporate data on z/OS. For instance, z/OS can run WebSphere applications alongside DB2®, to enable tight, security-rich local connections ideal for high volume transactional throughput.

In this case, overhead through network protocols can be eliminated and CPU consumption can be reduced dramatically. Current z/OS applications can be extended with new programming language technologies and standards to deliver value in new and innovative ways without incurring the substantial cost required to replace current assets.

z/OS has made advances in open standards with each release. In z/OS V2.1, support is planned for three Japanese Industrial Standards (JIS) for Extended UNIX Code (EUC), JIS X 0201, JIS X 0208, and JIS X 0212; there is new support for the Unicode 6.0 standard, and support for the CIM Schema version 2.30, and the CIM Client for Java to version 2.17. In addition there are enhancements to meet many security standards.

z/OS supports a number of industry popular languages to develop software. Language Environment is the prerequisite runtime environment for applications generated with the following IBM compiler products:

●● ● XL C/C++ ●● ● Enterprise COBOL for z/OS ●● ● Enterprise PL/I for z/OS ●● ● IBM Rexx●● ● Java

Enhancements for Application Developmentz/OS V2.1 capabilities can help you develop or extend batch programs while optimizing performance so your batch window is shortened, enabling processing of more mission critical online work. The z/OS Batch Runtime environment is designed to form the foundation for resilient, highly available, secure, and scalable services for batch applications. The z/OS Batch Runtime can provide the framework for Java to COBOL interoperability, for transactional updates to DB2, and for sharing database connections between Java and COBOL. The new Java-COBOL interoperability capabilities are designed to enable you to reuse valuable COBOL assets by developing new or enhancing existing batch applications with Java.

Some recent enhancements in z/OS V2.1 include:

●● ● Batch Runtime Environment introduced originally to allow COBOL and Java programs to interoperate while sharing a DB2 database with transactional integrity between multiple users. New support is now planned for PL/I programs in z/OS V2.1 in addition to COBOL and Java programs to provide more f lexibility for extending existing applications. In addition, plans to support recoverable record-level sharing data sets processed using transactional VSAM in addition to DB2 are designed to increase the scope of z/OS Batch Runtime environment

●● ● Support for the IBM Batch Programming Model is being introduced to allow Java applications to conform to a stan-dard batch programming model, making them more portable among supported environments

●● ● Support for new C/C++ instructions and facilities on the IBM zEC12 with new ARCH (1) and TUNE (10)

●● ● Options are intended to improve code optimization on zEC12 servers. New functions to support transactional execu-tion are intended to reduce locking and improve performance

●● ● Support for a new HEAPZONES option that programmers can use to expose memory overlays that can cause heap damage

●● ● For printing convenience z/OS V2.1 is planned to include all fonts included in the AFP Font Collection for S/390 and in IBM Infoprint Fonts for z/OS V1.1 as well as World Type fonts that were not previously available in the z/OS environment

●● ● PDSE processing is planned to be enhanced with a new PDSE Version 2 format designed to allow all unused space to be released, consolidate directory pages, improve read performance, and reduce virtual storage utilization for PDSE processing

Excellence in Workload Management and Resource OptimizationWith the ability to intelligently manage workloads, dynamically allocate system resources to applications quickly and efficiently and dynamically provision additional server capacity according to policy, z/OS and System z are designed to handle workload spikes so you can deliver availability to meet business priorities. The z/OS Workload Manager is at the hub of this capability. The z/OS Workload Manager is a key element contributing to z/OS’ leadership in smarter computing and is designed to manage the processing of mixed diverse workloads according to business goals, including response time goals. With WLM you define performance goals and assign a business importance to

9

Data SheetSystem zIBM Systems and Technology

each goal in business terms. WLM then manages system resources such as processors and storage to help attain these goals. Then z/OS decides how much resource, such as CPU or storage, is needed to meet the goal and will constantly monitor and adapt processing to meet the service goals. This policy can also be used to manage service across the entire sysplex to provide a single point of control, and can eliminate the need for individual image management.

The scope of the Workload Manager extends from managing incoming TCP/IP and SNA traffic, to managing requests for I/O. Middleware like DB2, CICS, IMS, WebSphere MQ and other WebSphere products can take advantage of z/OS WLM to manage the priority and execution of transaction requests across the z/OS system. In addition, z/OS WLM can send basic data to zManager for use in monitoring cross-platform zEnterprise ensembles.

In z/OS V2.1 WLM is enhanced to support up to 3,000 appli-cation environments, up from the prior limit of 999.to make it easier to maintain common service definitions for multiple sysplexes and to provide support for the growth of large DB2 environments. Customers with large SAP DB2 environ-ments or who use common WLM service definitions across a number of sysplexes are expected to be able to benefit from this raised limit as well.

In z/OSV2.1 for improved performance visibility, RMF pro-vides a new SMF record on performance related information for Linux on System z, Linux on System x, AIX operating sys-tems running on zBX blades and Microsoft Windows 2008 Server running on zBX blades. This can help depict overall perspective on performance and capacity for the zEnterprise hybrid environment.

SimplificationYou need solutions that are easy to manage and operate so that your expert skills can be optimally deployed. To meet this challenge, z/OS continues to simplify diagnosis and problem determination; network and security management; as well as overall configuration and operations. These improvements can help simplify systems management, improve application programmer, system programmer, and operator productivity, and make management more intuitive through functions that are easier to understand and use:

z/OS Management Facility (z/OSMF, 5655-S28) forms the platform for revolutionizing the management of z/OS environ-ments. z/OSMF is a no charge product for z/OS that provides support for a web browser-based management console that is designed to help companies more easily administer a mainframe by simplifying day-to-day configuration, and management of z/OS system software. In addition to providing an easy to use intuitive graphical user interface, the z/OS Management Facility addresses skills needs, maximizing productivity and helping organizations create a repeatable and more standardized management approach. z/OSMF automation is designed to help reduce the learning curve and its active user assistance helps guide users through tasks, simplifying operations.

New z/OSMF V2.1 Enhancements Include the Following:●● ● Reduce the complexity of configuring z/OS with z/OSMF

V2.1. z/OSMF V2.1 introduces new Software Management to help manage the currency of your z/OS SMP/E installed software portfolio displaying results at a glance. New report-ing capabilities are designed to check inventory information and new panels show product end of service information and needed fixes.

●● ● A new workflow application is designed to provide configura-tion assistance using role-based routing of tasks to help with the sequencing of configuration work steps needed. The z/OSMF Workflow Application will allow exploiters to provide configuration assistance simplifying z/OS configu-ration and setup.

10

Data SheetSystem zIBM Systems and Technology

●● ● The Capacity Provisioning Manager application is planned to help you manage your configuration policies for on/off Capacity on Demand. The Capacity Provisioning Manager application replaces the Microsoft Windows based Capacity Provisioning Control Center (CPCC).

●● ● Use of the Liberty profile in WebSphere Application Server OEM (WASOEM) for z/OS, V8.5 in z/OMF V2.1 is expected to provide significant reductions in the resource requirements and simplify setup.

●● ● z/OSMF V2.1 offers a simplified z/OS user experience with a new REST interface to enable z/OS and non z/OS systems to submit z/OS jobs, obtain job status, and retrieve job output easily.

For more information on the z/OS Management Facility, see: ibm.com/systems/z/os/zos/zosmf/

Specialty Engines for Improved EconomicszAAPs and zIIPs are designed to help implement, integrate, and optimize new technologies on z/OS. z/OS allows authorized workloads to be redirected off of general purpose processors on to the IBM System z Application Assist Processor (zAAP) and IBM System z Integrated Information Processor (zIIP) specialty engines. The zAAP was designed to support z/OS Java and z/OS XML processing, and helps improve the cost effectiveness of running new application technologies on z/OS. The zIIP was originally designed to support data and transaction processing, but now supports many more types of workloads. For a listing of zAAP and zIIP authorized workloads, see: ibm.com/systems/z/hardware/features/

Beginning with z/OS V1.11, z/OS enabled zAAP eligible workloads to run on zIIPs—ideal for customers without enough zAAP- or zIIP-eligible workload to justify a specialty engine. This capability is intended to provide more value for customers

having only zIIP processors by making Java- and XML-based workloads eligible to run on existing zIIPs. Customers need to purchase and maintain one or more general purpose processors for every zIIP processor on the server. Additional terms and conditions apply.

Note: The IBM zEC12 is planned to be the last high-end System z server to offer support for zAAP specialty engine processors. IBM intends to continue support for running zAAP workloads on zIIP processors (“zAAP on zIIP”).

Compatibilityz/OS gives you compatibility and f lexibility to run multiple releases of z/OS together on the same system, or within a multisystem Parallel Sysplex. For example, see the following coexistence capabilities:

●● ● z/OS V1.12 coexists with: z/OS V1.10, z/OS V1.11, z/OS V1.12, z/OS V1.13, z/OS V2.1
