Guide to the Secure Configuration of Webmin
scap-security-guide
package which is developed at
https://www.open-scap.org/security-policies/scap-security-guide.
Providing system administrators with such guidance informs them how to securely configure systems under their control in a variety of network roles. Policy makers and baseline creators can use this catalog of settings, with its associated references to higher-level security control catalogs, in order to assist them in security baseline creation. This guide is a catalog, not a checklist, and satisfaction of every item is not likely to be possible or sensible in many operational scenarios. However, the XCCDF format enables granular selection and adjustment of settings, and their association with OVAL and OCIL content provides an automated checking capability. Transformations of this document, and its associated automated checking content, are capable of providing baselines that meet a diverse set of policy objectives. Some example XCCDF Profiles, which are selections of items that form checklists and can be used as baselines, are available with this guide. They can be processed, in an automated fashion, with tools that support the Security Content Automation Protocol (SCAP). The DISA STIG for Webmin, which provides required settings for US Department of Defense systems, is one example of a baseline created from this guidance.

Introduction [ref]groupThe purpose of this guidance is to provide security configuration recommendations and baselines for the Webmin application. Recommended settings for the basic application are provided. The guide is intended for system administrators. Readers are assumed to possess basic system administration skills for Unix-like systems, as well as some familiarity with the product's documentation and administration conventions. Some instructions within this guide are complex. All directions should be followed completely and with understanding of their effects in order to avoid serious adverse effects on the system and its security. |
How to Use This Guide [ref]groupReaders should heed the following points when using the guide. |
Read Sections Completely and in Order [ref]groupEach section may build on information and recommendations discussed in prior sections. Each section should be read and understood completely; instructions should never be blindly applied. Relevant discussion may occur after instructions for an action. |
Test in Non-Production Environment [ref]groupThis guidance should always be tested in a non-production environment before deployment. This test environment should simulate the setup in which the system will be deployed as closely as possible. |
Root Shell Environment Assumed [ref]group
Most of the actions listed in this document are written with the
assumption that they will be executed by the root user running the
