Guide to the Secure Configuration of Red Hat Enterprise Linux CoreOS 4
with profile DRAFT - BSI APP.4.4. and SYS.1.6This profile defines a baseline that aligns to the BSI (Federal Office for Security Information) IT-Grundschutz Basic-Protection. This baseline implements OS-Level configuration requirements from the following sources: - Building-Block SYS.1.6 Containerisation - Building-Block APP.4.4 Kubernetes THIS DOES NOT INCLUDE REQUIREMENTS FOR A HARDENED LINUX FROM SYS.1.3 LINUX

This guide presents a catalog of security-relevant
configuration settings for Red Hat Enterprise Linux CoreOS 4. It is a rendering of
content structured in the eXtensible Configuration Checklist Description Format (XCCDF)
in order to support security automation. The SCAP content is
is available in the
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, which provides required settings for US Department of Defense systems, is one example of a baseline created from this guidance.

SELinux is a feature of the Linux kernel which can be
used to guard against misconfigured or compromised programs.
SELinux enforces the idea that programs should be limited in what
files they can access and what actions they can take.
The default SELinux policy, as configured on Red Hat Enterprise Linux CoreOS 4, has been sufficiently developed and debugged that it should be usable on almost any system with minimal configuration and a small amount of system administrator training. This policy prevents system services - including most of the common network-visible services such as mail servers, FTP servers, and DNS servers - from accessing files which those services have no valid reason to access. This action alone prevents a huge amount of possible damage from network attacks against services, from trojaned software, and so forth. This guide recommends that SELinux be enabled using the default (targeted) policy on every Red Hat Enterprise Linux CoreOS 4 system, unless that system has unusual requirements which make a stronger policy appropriate. | ||||||||||||||||||||||||||||||||||||||||||||||||
