Systemd Announces 'run0' Sudo Alternative

Posted: 2024-04-30 23:00:00
Source: https://tech.slashdot.org/story/24/04/30/219252/systemd-announces-run0-sudo-alternative?utm_source=atom1.0mainlinkanon&utm_medium=feed

An anonymous reader quotes a report from Foss Outpost: Systemd lead developer Lennart Poettering has posted on Mastodon about their upcoming v256 release of Systemd, which is expected to include a sudo replacement called "run0". The developer talks about the weaknesses of sudo, and how it has a large possible attack surface. For example, sudo supports network access, LDAP configurations, other types of plugins, and much more. But most importantly, its SUID binary provides a large attack service according to Lennart: "I personally think that the biggest problem with sudo is the fact it's a SUID binary though -- the big attack surface, the plugins, network access and so on that come after it it just make the key problem worse, but are not in themselves the main issue with sudo. SUID processes are weird concepts: they are invoked by unprivileged code and inherit the execution context intended for and controlled by unprivileged code. By execution context I mean the myriad of properties that a process has on Linux these days, from environment variables, process scheduling properties, cgroup assignments, security contexts, file descriptors passed, and so on and so on." He's saying that sudo is a Unix concept from many decades ago, and a better privilege escalation system should be in place for 2024 security standards: "So, in my ideal world, we'd have an OS entirely without SUID. Let's throw out the concept of SUID on the dump of UNIX' bad ideas. An execution context for privileged code that is half under the control of unprivileged code and that needs careful manual clean-up is just not how security engineering should be done in 2024 anymore." [...] He also mentioned that there will be more features in run0 that are not just related to the security backend such as: "The tool is also a lot more fun to use than sudo. For example, by default, it will tint your terminal background in a reddish tone while you are operating with elevated privileges. That is supposed to act as a friendly reminder that you haven't given up the privileges yet, and marks the output of all commands that ran with privileges appropriately. It also inserts a red dot (unicode ftw) in the window title while you operate with privileges, and drops it afterwards."

Developing Robust Integration of Linux and IoT Solutions

Posted: 2024-04-30 16:00:00

by George Whittaker

The Internet of Things (IoT) represents a vast frontier for innovation, promising to connect and automate our world in ways we're just beginning to understand. Linux, known for its stability, security, and open-source nature, stands as a preferred operating system for many IoT devices. This article delves into how you can leverage Linux to build powerful, reliable, and secure IoT solutions.

Introduction to IoT and Linux

IoT involves the extension of internet connectivity into physical devices and everyday objects. These devices can communicate and interact with others over the internet, and they can be remotely monitored and controlled. With the proliferation of IoT devices in various sectors—from industrial automation and smart homes to healthcare—the need for robust underlying systems that can handle security, connectivity, and scalability issues is paramount.

Linux, with its versatility across different hardware platforms and its robustness, has become a go-to choice for IoT applications. It supports a range of architectures from high-power servers to low-power microcontrollers, making it ideal for the diverse needs of IoT devices.

Understanding IoT and Linux Basics

Key Concepts of IoT

IoT ecosystems consist of web-enabled smart devices that use embedded systems, such as processors, sensors, and communication hardware, to collect, send and act on data they acquire from their environments. IoT devices share the sensor data they collect by connecting to an IoT gateway or other edge device where data is either sent to the cloud to be analyzed or analyzed locally.

Why Linux for IoT?

Linux offers several advantages for IoT systems:

• Stability and Reliability: Linux is known for its stability, which is crucial for devices that need to run continuously without failure.
• Security: With advanced features like SELinux, Linux provides robust security, which is critical for IoT devices that are often targets for cyber attacks.
• Open Source: Linux’s open-source nature allows developers to customize and secure their operating systems based on their specific needs.

Selecting the Right Hardware

Choosing the right hardware is critical as it influences both the performance and the capabilities of the IoT solution. When selecting hardware for Linux-based IoT devices, consider:

ReneR writes: A major T2 Linux milestone has been released, shipping with full support for 25 CPU architectures and several C libraries, as well as restored support for Intel IA-64 Itanium. Additionally, many vintage X.org DDX drivers were fixed and tested to work again, as well as complete support for the latest KDE 6 and GNOME 46. T2 is known for its sophisticated cross compile support and support for nearly all existing CPU architectures: Alpha, Arc, ARM(64), Avr32, HPPA(64), IA64, M68k, MIPS(64), Nios2, PowerPC(64)(le), RISCV(64), s390x, SPARC(64), and SuperH x86(64). T2 is an increasingly popular choice for embedded systems and virtualization. It also still supports the Sony PS3, Sgi, Sun and HP workstations, as well as the latest ARM64 and RISCV64 architectures. The release contains a total of 5,140 changesets, including approximately 5,314 package updates, 564 issues fixed, 317 packages or features added and 163 removed, and around 53 improvements. Usually most packages are up-to-date, including Linux 6.8, GCC 13, LLVM/Clang 18, as well as the latest version of X.org, Mesa, Firefox, Rust, KDE 6 and GNOME 46! More information, source and binary distribution are open source and free at T2 SDE.
