Every organization has a core set of mission-critical data that requires protection. Security lapses and failures are not simply disruptions, they can be catastrophic events with consequences felt across the enterprise. The inadvertent mistakes of privileged users alone can result in millions of dollars in damages through unintentional configuration errors and careless security commands. Malicious users with authorized access can cause even greater damage. As a result, security management faces a serious challenge to adequately protect a company's sensitive data. Likewise, IT staff is challenged to provide detailed audit and controls documentation in the face of increasing demands on their time. Automation and simplification of security and compliance processes can help you meet these challenges and establish effective, sustainable user administration and audit solutions. This includes security database cleanup, repeatable audit of configurations and settings, and active monitoring of changes and events. IBM Tivoli Security Management for z/OS V1.11 provides these solutions to help enhance the security of mainframe systems through automated audit and administration. In this IBM® RedpaperTM document we discuss how Tivoli® Security Management for z/OS® allows you to submit mainframe security information from z/OS, RACF®, and DB2® into an enterprise audit and compliance solution and how to combine mainframe data from z/OS, RACF, and DB2 with that from other operating systems, applications, and databases in order to provide the ability to capture comprehensive log data, interpret that data through sophisticated log analysis, and communicate results in an efficient, streamlined manner for full enterprise-wide audit and compliance reporting.
To comply with government and industry regulations, such as Sarbanes-Oxley, Gramm Leach Bliley (GLBA), and COBIT (which can be considered a best-practices framework), organizations must constantly detect, validate, and report unauthorized changes and out-of-compliance actions within the Information Technology (IT) infrastructure. Using the IBM® Tivoli Security Information and Event Manager solution organizations can improve the security of their information systems by capturing comprehensive log data, correlating this data through sophisticated log interpretation and normalization, and communicating results through a dashboard and full set of audit and compliance reporting. In this IBM Redbooks® publication, we discuss the business context of security audit and compliance software for organizations and describe the logical and physical components of IBM Tivoli Security Information and Event Manager. We also present a typical deployment within a business scenario. This book is a valuable resource for security officers, administrators, and architects who want to understand and implement a centralized security audit and compliance solution.
Non-compliance can lead to increasing costs. Regulatory violations involving data protection and privacy can have severe and unintended consequences. In addition, companies must keep pace with changes that arise from numerous legislative and regulatory bodies. Global organizations have the added liability of dealing with national and international-specific regulations. Proving that you are compliant entails compiling and organizing data from multiple sources to satisfy auditor's requests. Preparing for compliance audits can be a major time drain, and maintaining, updating, and adding new processes for compliance can be a costly effort. How do you keep constant changes to regulations and your security posture in check? It starts with establishing a baseline: knowing and understanding your current security posture, comparing it with IBM Z® security capabilities, and knowing the latest standards and regulations that are relevant to your organization. IBM Z Security and Compliance Center can help take the complexity out of your compliance workflow and the ambiguity out of audits while optimizing your audit process to reduce time and effort. This IBM Redbooks® publication helps you make the best use of IBM Z Security and Compliance Center and aid in mapping all the necessary IBM Z security capabilities to meet compliance and improve your security posture. It also shows how to regularly collect and validate compliance data, and identify which data is essential for auditors. After reading this document, you will understand how your organization can use IBM Z Security and Compliance Center to enhance and simplify your security and compliance processes and postures for IBM z/OS® systems. This publication is for IT managers and architects, system and security administrators
Every organization has a core set of mission-critical data that must be protected. Security lapses and failures are not simply disruptions—they can be catastrophic events, and the consequences can be felt across the entire organization. As a result, security administrators face serious challenges in protecting the company's sensitive data. IT staff are challenged to provide detailed audit and controls documentation at a time when they are already facing increasing demands on their time, due to events such as mergers, reorganizations, and other changes. Many organizations do not have enough experienced mainframe security administrators to meet these objectives, and expanding employee skillsets with low-level mainframe security technologies can be time-consuming. The IBM® Security zSecure suite consists of multiple components designed to help you administer your mainframe security server, monitor for threats, audit usage and configurations, and enforce policy compliance. Administration, provisioning, and management components can significantly reduce administration, contributing to improved productivity, faster response time, and reduced training time needed for new administrators. This IBM Redbooks® publication is a valuable resource for security officers, administrators, and architects who wish to better understand their mainframe security solutions.
Discussions about server sprawl, rising software costs, going green, or moving data centers to reduce the cost of business are held in many meetings or conference calls in many organizations throughout the world. And many organizations are starting to turn toward System zTM and z/VM® after such discussions. The virtual machine operating system has over 40 years of experience as a hosting platform for servers, from the days of VM/SP, VM/XA, VM/ESA® and especially now with z/VM. With the consolidation of servers and conservative estimates that approximately seventy percent of all critical corporate data reside on System z, we find ourselves needing a highly secure environment for the support of this infrastructure. This document was written to assist z/VM support and security personnel in providing the enterprise with a safe, secure and manageable environment. This IBM® Redbooks® publication provides an overview of security and integrity provided by z/VM and the processes for the implementation and configuration of z/VM Security Server, z/VM LDAP Server, IBM Tivoli® Directory Server for z/OS®, and Linux® on System z with PAM for LDAP authentication. Sample scenarios with RACF® database sharing between z/VM and z/OS, or through Tivoli Directory Integrator to synchronize LDAP databases, are also discussed in this book. This book provides information about configuration and usage of Linux on System z with the System z Cryptographic features documenting their hardware and software configuration. The Consul zSecure Pro Suite is also part of this document: this product helps to control and audit security not only on one system, but can be used as a single point of enterprise wide security control. This document covers the installation and configuration of this product and detailed information is presented on how z/Consul can be used to collect and analyze z/VM security data and how it can be helpful in the administration of your audit data.
