Understanding the Basics of SELinux Policy Management on CentOS
Posted: 2024-05-07 16:00:00 Source: https://www.linuxjournal.com/content/understanding-basics-selinux-policy-management-centos
Introduction
In the vast ocean of Linux security, SELinux stands as a stalwart guardian, often misunderstood yet crucial for safeguarding systems against potential threats. As administrators and users delve deeper into the realms of CentOS, mastering SELinux policy management becomes imperative for ensuring robust security configurations. This article aims to demystify SELinux policy management on CentOS, providing an introduction to its intricacies and functionalities.
Understanding SELinux
SELinux, or Security-Enhanced Linux, represents a paradigm shift in Linux security by enforcing mandatory access controls (MAC) based on security policies. Unlike traditional discretionary access controls (DAC), which rely on user permissions, SELinux assigns security contexts to system objects, such as files, processes, and sockets. These contexts include labels denoting the object's type, role, and domain, allowing SELinux to enforce fine-grained access control decisions.
SELinux operates primarily in two modes: enforcing and permissive. In enforcing mode, SELinux actively enforces security policies, denying access to unauthorized actions. Conversely, permissive mode logs policy violations without enforcing them, facilitating policy development and troubleshooting.
SELinux Policy Basics
SELinux policies define the rules governing access control decisions within the system. CentOS typically utilizes targeted policies, which confine SELinux enforcement to specific system services and processes. In contrast, MLS policies enforce mandatory access controls based on sensitivity labels, suitable for high-security environments.
Key components of SELinux policies include Type Enforcement (TE), Role-Based Access Control (RBAC), and Multi-Level Security (MLS). TE governs access based on object types and their associated permissions, ensuring that processes operate within defined constraints. RBAC assigns roles to users and domains, dictating their access privileges within the system. MLS extends access controls to support multiple security levels, crucial for systems handling classified information.
SELinux Policy Management on CentOS
Managing SELinux policies on CentOS involves navigating various tools and utilities to configure and troubleshoot security settings effectively. Administrators can switch between enforcing and permissive modes using the setenforce command, allowing flexibility in policy enforcement.
Working with SELinux policy modules enables administrators to customize access controls for specific applications and services. CentOS provides tools like semodule for installing, managing, and creating custom policy modules tailored to system requirements. By encapsulating policy rules within modules, administrators can deploy targeted security configurations without modifying the core SELinux policy.

Ubuntu Criticized For Bug Blocking Installation of .Deb Packages
Posted: 2024-05-04 20:03:00 Source: https://news.slashdot.org/story/24/05/04/202207/ubuntu-criticized-for-bug-blocking-installation-of-deb-packages?utm_source=atom1.0mainlinkanon&utm_medium=feed
The blog It's FOSS is "pissed at the casual arrogance of Ubuntu and its parent company Canonical..... The sheer audacity of not caring for its users reeks of Microsoft-esque arrogance." If you download a .deb package of a software, you cannot install it using the official graphical software center on Ubuntu anymore. When you double-click on the downloaded deb package, you'll see this error, "there is no app installed for Debian package files". If you right-click and choose to open it with Software Center, you are in for another annoyance. The software center will go into eternal loading. It may look as if it is doing something, but it will go on forever. I could even livestream the loading app store on YouTube, and it would continue for the 12 years of its long-term support period. Canonical software engineer Dennis Loose actually created an issue ticket for the problem himself — back in September of 2023. And two weeks ago he returned to the discussion to announce that fix "will be a priority for the next cycle". (Though "unfortunately we didn't have the capacity to work on this for 24.04...) But Its Foss accused Canonical of "cleverly booting out deb in favor of Snap, one baby step at a time" (noting the problem started with Ubuntu 23.10): There is also the issue of replacing deb packages with Snap, even with the apt command line tool. You use 'sudo apt install chromium', you get a Snap package of Chromium instead of Debian The venerable Linux magazine argues that Canonical "has secretly forced Snap installation on users." [I]t looks as if the Software app defaults to Snap packages for everything now. I combed through various apps and found this to be the case.... As far as the auto-installation of downloaded .deb files, you'll have to install something like gdebi to bring back this feature.
