  • Running FIPS 140 workloads on Ubuntu | Ubuntu

    Even though cryptography is used by almost every application today, the implementation of it is usually delegated to specialized cryptographic libraries. There are multiple reasons for that, including that implementing cryptography is not easy, and in fact it is easy to get wrong. Small mistakes–such as reusing a nonce–may render the data encrypted by an application recognizable. At the same time, the security landscape changes so fast that secure software of 10 years ago can no longer withstand attacks that exploit newly discovered vulnerabilities. For instance, algorithms like RC4 that were dominant in the early days of Internet commerce are today considered broken.

    How can we be assured that these cryptographic applications and libraries implement cryptography correctly and follow best practices such as not using legacy cryptography? As cryptography is sensitive to governments around the world, there is no universally accepted answer yet. To address this problem in the U.S., NIST developed FIPS 140, a data protection standard that is our focus in this article.

    FIPS 140 defines security requirements related to the design and implementation of a cryptographic module, or in software terms, for an application or library implementing cryptography. The standard has multiple levels of security, from levels 1 to 4, with level 1 applying to software implementations, while level 2 and further applying to specialized hardware alongside its software. On level 1, the standard requires the use of known, secure cryptographic algorithms and modes for data protection and requires their logical separation from the application. It further includes a certification process that ensures that the claims are tested and attested by an accredited lab by NIST.

    In essence the FIPS 140 standard ensures that cryptography is implemented using well known secure designs, follows certain best practices, does not involve obscure algorithms, and that there is a due process in attestation.

  • Renewed FIPS 140-2 Validation For Red Hat Enterprise Linux 8.2 | TFiR: Interviews, News & Analysis by Swapnil Bhartiya

    Red Hat has announced the renewal of the Federal Information Processing Standard 140-2 (FIPS 140-2) security validation for Red Hat Enterprise Linux 8.2. The second FIPS certification for the Red Hat Enterprise Linux 8 platform, this validation indicates Red Hat’s leadership and commitment to providing a more secure backbone for the innovation of open hybrid cloud.

    With this validation for Red Hat Enterprise Linux 8.2, many of Red Hat’s open hybrid cloud offerings also retain the FIPS 140-2 certification as layered products building on Red Hat Enterprise Linux 8.2’s cryptography modules. These include but are not limited to: Red Hat Ceph Storage, Red Hat Gluster Storage, Red Hat OpenShift, Red Hat OpenStack Platform, Red Hat Satellite, and Red Hat Virtualization.

  • The 10 Best Tools to Scan Your Linux Server for Malware and Security Flaws

    Linux is downright one of the most popular and secure operating systems for large-scale servers. Despite its widespread usage, it remains vulnerable to cyberattacks. Hackers target servers to either shut them down or steal valuable information.

    There is a pressing need to develop counter-hacking methods to brace security breaches and malware attacks. This is possible by hiring cybersecurity professionals; unfortunately, this can prove to be a costly affair. The next best solution is to install scanning tools that fit like a hand in glove for your Linux systems.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. 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.
