data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

security enhancementsecurity featureselinuxSELinux 6.4: No Runtime Disabling Support For Enhanced Security
After being deprecated for several years, Security Enhanced Linux "SELinux" beginning with the Linux 6.4 kernel can no longer be run-time disabled. . For a while now SELinux deprecated run-time disabling for turning off SELinux via its config file or sysfs. By getting rid of the run-time disabling support, SELinux developers can make various improvements currently blocked by this code. Those wishing to disable SELinux support can still do so via the selinux=0 boot time option or when building the Linux kernel toggling the "CONFIG_SECURITY_SELINUX_DISABLE" Kconfig switch. The SELinux run-time disabling removal is made as part of this pull request pending for the newly-opened Linux 6.4 merge window.

security practicessystem hardeningLinux administrationThe Essential Reasons for Keeping SELinux Active for Optimal Security
Too many admins disable SELinux or set it to Permissive on their data center systems, as opposed to spending the necessary time to make the projects they're working on work with SELinux. Jack Wallen warns that admins are playing with fire by shrugging off SELinux, leaving their OSes weakened and susceptible to attacks. . Given the kerfuffle that has been CentOS lately, and the number of inevitable forks that will rise out of the ashes, there will probably be a large percentage of admins migrating to, or finally deploying, a Linux distribution based on Red Hat Enterprise Linux in some form or fashion. It may be Rocky Linux or AlmaLinux . It may be that you stick with CentOS Stream , or even purchase a license for Red Hat Enterprise Linux . If you're a non-profit or another eligible organization, you might qualify for RHEL for Open Source Infrastructure . No matter which route you take, you'll be using a solid Linux distribution with serious security systems in place. However... It's such a powerful word, "however." It stops all natural flow of the narrative to make you wonder just what comes next. You wait, and you wait, and you wait. Until the inevitable: SELinux. . Numerous administrators opt to deactivate SELinux or configure it in Permissive mode, jeopardizing overall system security. Discover the reasons this approach needs to change..

So it. However, to put it bluntly most architects and network guys turn SELinux off when building out platforms and virtualised instances which is quite short sighted. When I do pose the question why a lot of responses are aligned to the fact that SELinux can sometimes due to configuration issues and past experiences where stuff broke and was hard to diagnose so easier to just turn off.

security featureselinuxsandboxSELinux Sandbox Talks by Dan Walsh at LinuxCon Event in 2023
SELinux is a great way to limit the access rights/roles on a Linux machine. But how do you limit CPU or memory usage of a given application? Red Hat engineer Dan Walsh has a solution that he calls SELinux Sandbox which he demoed at the LinuxCon conference today.. Walsh stressed that he's not trying to replace virtualization with SELinux sandboxing, but he is trying to create an easier way to isolate and control applications.

Security Enhanced Linux has move into the mainstream of operating system architecture in recent years. For those who don't understand the technology, many articles exist. SELinux provides mandatory access control to a wider audience. It helps eliminate O-day attacks. The agenda for the 2006 SELinux Symposium has just been announced and some project leaders of Linux distributions may way want to attended. . Existing distributions such as Fedora are including SELinux in the default build, and ports are underway to bring SELinux functionality to BSD and Darwin. Management has already stressed the importance of SELinux in many organizations. So, security minded systems administrators will find SELinux an important area to gain proficiency.

intrusion detectionmandatory access controlopen sourceEnhancing Linux Security With SELinux, RSBAC, And Other MAC Projects
Some in the security industry say that Linux is inherently insecure, that the way Linux enforces security decsions is fundamentally flawed, and the only way to change this is to redesign the kernel. Fortunately, there are a few projects aiming to solve this problem by providing a more robust security model for Linux by adding Mandatory Access Control (MAC) to the kernel. . The most well-known of these projects is Security Enhanced Linux (SELinux), which was developed by the U.S. National Security Agency (NSA). The Rule Set Based Access Control (RSBAC) project, the Linux Intrusion Detection System (LIDS), and grsecurity are other popular projects with the same goal. All of these projects are open-source and licensed under the GPL. The link for this article located at Linux.com is no longer available. .

security advisoryfedora coreaccess controlFedora Core 2 Test: Security Enhancements in SELinux Features
Red Hat Inc. announced Thursday the release of a test version of Fedora Core 2 that is based on the recently released 2.6 Linux kernel. Our readers are probably already aware that 2.6 integrates a whole lot more security into the kernel than was previously the case, including hooks for SELinux, IPSec, and ACLs. Fedora is a hobbyist version of Linux that is constantly being updated and likely does not offer the stability an enterprise would require for its mission-critical systems. This is the first of three phases of the Fedora Core 2 release schedule, which runs through April 19, said Brian M. Stevens, vice president of engineering. . . .. Red Hat Inc. announced Thursday the release of a test version of Fedora Core 2 that is based on the recently released 2.6 Linux kernel. Fedora is a hobbyist version of Linux that is constantly being updated and likely does not offer the stability an enterprise would require for its mission-critical systems. This is the first of three phases of the Fedora Core 2 release schedule, which runs through April 19, said Brian M. Stevens, vice president of engineering. Stevens said that Red Hat on Thursday also released the alpha version of the next installment of Red Hat Enterprise Linux to OEMs, partners and large customers for review. Fedora Core 2 is based not only on the 2.6 kernel, but also on Security-Enhanced Linux (SELinux), a hardened version of Linux developed by the National Security Agency. SELinux includes "strong, flexible mandatory access control architecture incorporated into the major subsystems of the kernel," according to the NSA's Web site. "The system provides a mechanism to enforce the separation of information based on confidentiality and integrity requirements." Red Hat is hoping for feedback from developers and testers that can be taken into account as subsequent test versions are developed. This is the first 2.6 distribution available for public review, and Stevens expects the feedback Red Hat receives to be crucial to the continuing development of the2.6 kernel. "You never expect [the feedback] you get back," Stevens said. "It's always the unknowns that are interesting. This is critical exposure." In this test version, Stevens said SELinux must be booted separately for it to work. Stevens noted that the policy around SELinux needs to be refined. He expects that the second test version of Fedora will have SELinux turned on by default. The link for this article located at techtarget.com is no longer available. .
