Classic Confinement in Snaps and Reasons Flatpaks and Snaps Are Great for GNU/Linux

Filed under

  • The new classic confinement in snaps – Even the classics need a change | Ubuntu

    As part of their fundamental, security-driven design, snaps are meant to run isolated from the underlying system. In most cases, the idea works well, and granular access to system resources using the mechanism of interfaces allows snap developers to ship their applications packaged with strict confinement.

    However, there are some scenarios where even the liberal use of interface plugs cannot fully satisfy all of the functional requirements of specific applications. Certain programs need system-wide access to directories and files, and others may need to execute arbitrary binaries as part of their run. To that end, snaps can also be installed in the “classic” confinement mode, which gives them access similar to what the application would have if installed in the traditional way. The solution works, but now, there are proposals to make the classic mode even more robust and efficient.

  • 6 Reasons Flatpaks and Snaps Are Great for Linux

    Getting software on Linux has long been both simple and complicated. Many programs are just a mouse-click or terminal command away. But if the apps available for your chosen version of Linux are outdated, then getting the latest updates could often be a real pain.

    With both Flatpak and Snap, that has changed. Introducing more package formats in a crowded landscape sounds complicated, but they have made daily life on a Linux desktop much easier to manage. Let’s look at why.

Security features in Red Hat Enterprise Linux 9

Filed under
Red Hat

Red Hat Enterprise Linux 9 (RHEL 9) is the latest version of Red Hat’s flagship operating system, released at the Red Hat Summit in May 2022. New capabilities added to RHEL 9 help simplify how organizations manage security and compliance when deploying new systems or managing existing infrastructure. This article takes a brief look at three of the new security features available in this release.

The default superuser account in Unix- and Linux-based systems is "root". Because the username is always "root" and access rights are unlimited, this account is the most valuable target for hackers. Attackers use bots to scan for systems with exposed SSH ports, and when found, they attempt to use common usernames and brute-force passwords to gain entry. Of course, the impact of a successful exploit would be a lot lower if the compromised user has unprivileged access. The breach would then be contained and limited to one user only.

  • On the Dangers of Cryptocurrencies and the Uselessness of Blockchain

    Earlier this month, I and others wrote a letter to Congress, basically saying that cryptocurrencies are an complete and total disaster, and urging them to regulate the space. Nothing in that letter is out of the ordinary, and is in line with what I wrote about blockchain in 2019. In response, Matthew Green has written—not really a rebuttal—but a “a general response to some of the more common spurious objections…people make to public blockchain systems.”

  • 4 CNCF Projects For Key Management - Container Journal

    The nuances of cloud-native architecture necessitate some new approaches to security. Not only are container-based microservices inherently distributed, but there is a rising number of dependencies within the software supply chain. As a result, developers are faced with storing and accessing many types of secrets, including API keys, encryption keys, JSON Web Tokens (JWTs) and others when building cloud-native applications based on containers and running on platforms like Kubernetes. But, leaving such secrets exposed within your codebase goes against security best practices, as an attacker could easily access them.

    Software components must verify every request is coming from a legitimate source, known as authentication, and they must confirm the requesting party has the required permissions to access a resource, known as authorization. As part of this mission, we’ve seen a lot of development activity around automating secret issuance and distribution to securely store and distribute passwords among services.

  • How to Build Organizational Resilience to Cyberattacks [Ed: Can we stop assuming everyone uses Windows or that Windows security is possible/can be salvaged? Security is not part of the goals. Also, alcohol isn't medicine.]

    I became quite interested in cybersecurity around a year ago, given the growing threats of cyberattacks by criminal groups and adversarial governments. I then joined CAMS, MIT’s interdisciplinary cybersecurity consortium and started attending its online weekly seminars. A few weeks ago I attended a CAMS seminar on cyber resilience by Manuel Hepfer, a research affiliate at Oxford University and a research analyst at ISTARI, a cyber risk management company.

    What is cyber resilience? While cybersecurity is the practice of protecting critical systems and sensitive information from digital attacks, cyber resilience is the ability to prepare for, withstand, and recover rapidly from any major disruption, whether an intentional cyberattack or a natural disaster.

    The seminar was based on a study by Hepfer and colleagues of the 2017 NotPetya ransomware attacks, a series of powerful cyberattacks which caused over $10 billion in global economic damage across a number of industries. Their study was primarily focused on three global companies that were the subject of NotPetya attacks: a logistics company with over 60,000 employees, a manufacturing one with over 20,000 employees, and a third in professional services with over 5,000 employees.

  • Prioritize people during cultural transformation in 3 steps

    For the past few years, organizations have focused on finding technologies and processes that enable their employees to work from home. But with C-suites and HR professionals investing enormous resources into tools and processes, many are doing so without fully considering the most crucial piece of an agile enterprise – the people.

    To optimize performance in this new agile work era, boost employee morale, and recruit and retain the best talent amid a global-scale hiring crisis, organizations also need to address the needs of their workforce.

    As more employees voice their needs and concerns regarding their work lives, here are three ways to prioritize the people within your organization.

  • Create a more diverse and equitable open source project with open standards

    This article is intended to serve as a reference so that you can understand everything you need to be proud of your repository and make your open source project more open. By using open standards, an open source project improves its quality and shareability, since such standards exist to foster better communication between creators and consumers of the project. Most importantly, open standards can guide technology development by gently enforcing space for diversity and equity.

  • Boot into an Older Kernel By Default in Ubuntu & Other Linux

    Here’s a possible scenario. Your system received a kernel update but somehow things are not working as smoothly as previously.

    You realized that if you boot into the older kernel (yes, you can downgrade kernel), things are back to normal.

    That makes you happy with a little inconvenience. You have to manually select the older kernel at each boot.

    This problem was faced by an elderly It’s FOSS reader. The new kernel update in Linux Mint wasn’t working as expected. Booting into the older kernel ‘fixed’ the issues but choosing the older kernel at each boot was a problem.

    Removing the new kernel (while using the older kernel) is not a good idea because the new kernel will be installed and used with the next system updates.

    So, I suggested booting into the older Linux kernel by default. How to do that? That’s what I am going to show you in this tutorial.

The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
