IBM 10 SP1 EAL4 Purpose of this document, Document overview, Conventions used in this document

1 Introduction

This document describes the High Level Design (HLD) for the SUSE® Linux® Enterprise Server 10 Service Pack 1 operating system. For ease of reading, this document uses the phrase SUSE Linux Enterprise Server and the abbreviation SLES as a synonym for SUSE Linux Enterprise Server 10 SP1.

This document summarizes the design and Target of Evaluation Security Functions (TSF) of the SUSE Linux Enterprise Server (SLES) operating system. Used within the Common Criteria evaluation of SUSE Linux Enterprise Server at Evaluation Assurance Level (EAL) 4, it describes the security functions defined in the Common Criteria Security Target document.

1.1Purpose of this document

The SLES distribution is designed to provide a secure and reliable operating system for a variety of purposes. This document describes the high-level design of the product and provides references to other, more detailed design documentation that describe the structure and functions of the system. This document is consistent with additional high-level design documents, as well as with the supporting detailed design documents for the system. There are pointers to those documents in this document.

The SLES HLD is intended as a source of information about the architecture of the system for any evaluation team.

1.2Document overview

This HLD contains the following chapters:

Chapter 2 presents an overview of the IBM® eServer™ systems, including product history, system architecture, and TSF identification.

Chapter 3 summarizes the eServer hardware subsystems, characterizes the subsystems with respect to security relevance, and provides pointers to detailed hardware design documentation.

Chapter 4 expands on the design of the TSF software subsystems, particularly the kernel, which is identified in Chapter 2.

Chapter 5 addresses functional topics and describes the functionality of individual subsystems, such as memory management and process management.

Chapter 6 maps the Target of Evaluation (TOE) summary specification from the SUSE Linux Enterprise Server Security Target to specific sections in this document.
