Knowledge Discovery 25.4
Getting Started Guide

# Security Overview

OpenText provides the software infrastructure that automates operations on unstructured information. This software infrastructure is based on Knowledge Discovery.

Document security protects the information that you index into the Content component.

Your organization is likely to store information in many repositories. Many of these repositories have security features that apply permissions to files, so that they only authorized personnel can view them. Document security ensures that when you index information into Knowledge Discovery, Knowledge Discovery continues to enforce these permissions. In response to a query, the Content component returns only documents that a user is permitted to view.

Knowledge Discovery includes the following features to protect your data:

- User authentication. At the front end, users must log on before they can query Knowledge Discovery. The Community component can authenticate users against an existing directory service, such as Microsoft Active Directory.

- Document security. Many data repositories have security features that apply permissions to files, so that only authorized users can view them. Document security maintains these access restrictions in your Knowledge Discovery index, so that queries return only documents that the logged-in user has permission to view.

- Index Encryption. You can encrypt your Knowledge Discovery text index on disk, to prevent unauthorized access. For more information about index encryption, refer to the Content Component Help.

- Secure communications. Knowledge Discovery supports TLS/SSL for secure communications. Knowledge Discovery also supports GSSAPI for authentication and secure communications.
