Labels, clearances, and handling instructions are used to protect information on a system that is configured with the Oracle Solaris' Trusted Extensions feature. The components of labels, clearances, and handling instructions are specified in the label_encodings file. This guide provides background for creating or modifying the file. The guide provides examples, and helps you to create and install a label_encodings file that is appropriate for your site.
This book is for security administrators. Security administrators are responsible for defining the organization's labels. Some security administrators are also responsible for implementing the labels. This book is for definers and implementers.
Note - Labels are always being used. Labels provide mandatory access control (MAC), and MAC is always enforced. Therefore, the site's label_encodings file must be in place before any users or roles are created.
Trusted Extensions installs a default label_encodings file. The security administrator must provide a file that is appropriate for the site.
The security administrator who implements the labels should be familiar with Solaris administration. The necessary level of knowledge can be acquired through training and documentation. For details, see Documentation, Support, and Training.
The Solaris Trusted Extensions documentation set supplements the documentation for the Solaris release. Review both sets of documentation for a more complete understanding of Solaris Trusted Extensions. The following table lists the topics that are covered in the Solaris Trusted Extensions guides and the audience for each guide.
Chapter 1, Labels in Trusted Extensions Software discusses labels-related concepts for the security administrator who prepares the site's label_encodings file.
Chapter 2, Planning Labels (Tasks) provides planning steps for the security administrator who prepares the site's label_encodings file. This chapter also describes the encodings files that Trusted Extensions provides.
Chapter 3, Making a Label Encodings File (Tasks) describes how to create, customize, and check the label_encodings file.
Chapter 4, Labeling Printer Output (Tasks) describes the labels and handling instructions on printer output and gives procedures for modifying them.
Chapter 5, Customizing LOCAL DEFINITIONS describes the optional LOCAL DEFINITIONS section of the label_encodings file.
Chapter 6, Example: Planning an Organization's Labels models how a site analyzes its label requirements and creates a label_encodings file.
Appendix A, Sample Label Encodings File contains the example of the label_encodings file from Chapter 6, Example: Planning an Organization's Labels.
