Total data center and intranet automation capabilities
net security must adjust accordingly. In order to present a unified whole, the goal is to insulate the administrator from the specific vagaries of each system.
Having the software solutions needed to provide comprehensive sys-tems and data center intranet security management on each platform in the intranet is a significant part of mastering distributed systems and in-tranet security management. These solutions alone are only effective, however, if they can be tied together into a single point of management. Systems and intranet security administrators must be able to manage all or any desired part of the enterprise from any location within the intra-net. Single point of management allows administrators to implement and enforce overall enterprise policies while continuing to provide the local controls necessary in a constantly changing environment to ensure re-sponsiveness.
3. It provides a flexible user interface that enables each and every solu-tion within the data center environment to be managed from a single location or multiple locations if desired.
This third element is known as the systems and data center intranet se-curity management workstation, as shown in Exhibit 1, it provides sys-

For example, in an enterprise’s systems management workstation, the modern interface reduces the complexity of systems and intranet security management. It also provides an intuitive and logical view of otherwise complex issues. The GUI adjusts for the particular aspects of each envi-ronment, where necessary. For example, the user interface is identical when managing a multi-node job scheduler for defining jobs within job sets; or, schedules and their relationships to one another. However, when opening up a job detail window for actually setting up individual jobs, the GUI would present a job from an IBM MVS system as a collection of JCL (Job Control Language) statements. A job on UNIX would display as

Furthermore, an enterprise’s blueprint for a software architecture and its underlying guiding principles should try to provide a comprehensive strategy for software development for the IT community. This approach, where all components work together across multiple platforms, is essen-tial in maintaining sufficient responsiveness to the continually evolving priorities of enterprise-driven information processing requirements.
Automating each areaof systems and data center intranet security management does not in itself result in a complete and successful ap-proach to systems management. Each component of the systems and in-tranet security management solution must support and communicate with every other component in order to achieve total data center and in-tranet automation. For example, intranet-wide information security can-not be ensured if each systems management solution uses its own security tables. Problem and change management cannot keep pace with the dynamic activities of large and complex data center environments if software that addresses functions such as scheduling, report distribution, storage management, and security cannot automatically open and update problem incidents. Clearly, global workload management is unattainable unless each platform provides workload scheduling and resource balanc-ing capabilities that interface with all other platforms. Therefore, com-plete and effective integration requires both a design for integration and an architecture that support development and enhancement of the com-pletely integrated solution. As shown in Exhibit 2 for an IENF, an enter-prise’s services enable the integration of systems and data center intranet
