  • How our InfoSec Professionals stay one step ahead

    Our team knows the hacking world. We've recruited ethical hackers, OSCP-certified engineers, and seasoned IT professionals, all of whom are watching the dark web and its subversive operatives, watching how threats evolve and how attacks are planned. We routinely monitor zero-day exploits, examining use-cases thoroughly and responding with robust mitigation strategies.

    The fruits of intensive research and development are augmented by both human experience and machine learning. This sharpens our ability to produce timely and targeted WAF rule sets and blocking strategies in ways that no other security solution provider can match. To do our work, we must adopt the devious mind-set of a hacker. But we stay firmly attached to the ethical anchor of a trusted name in the Linux hosting world, CloudLinux.

  • No More Ransom, a global anti-ransomware initiative, announces ESET as new partner

    ESET has been announced as the latest partner of No More Ransom, an international initiative between Europol, the Dutch National Police and major cybersecurity organizations in the fight against ransomware. The collaborative project helps victims of ransomware attacks recover their personal data and has so far managed to decrypt the infected computers of 72,000 victims worldwide.

    With its 130 partners, the No More Ransom online portal hosts a collection of 59 free decryption tools from multiple security software vendors, covering 91 ransomware families. Users from around the world can access the tools for free in order to recover data held hostage by ransomware attacks. Launched in 2016, No More Ransom decryption tools have so far kept around USD 22 million out of the pockets of cybercriminals.

  • Passwords and Encryption

    More than just a boot manager, GRUB 2 can help you add another line of protection to your security defenses.

    A boot manager is almost as much of the Linux tradition as compiling a custom kernel. Traditionally, a boot manager has been used for choosing a kernel to start and for running multiple operating systems on a single computer. However, at a time when everybody is becoming security conscious, few are aware that GRUB 2, the most popular boot manager, is also capable of using passwords and encryption to provide another level of security [1]. Admittedly, GRUB 2 security is not enough by itself, but it is still worth adding to your in-depth defenses.

    GRUB 2 has existed for well over a decade and is rapidly replacing GRUB Legacy, the original version of the boot manager, especially in major distributions. As a result, its basic operation and traditional uses are reasonably well-known. However, before I dive into setting up passwords and encryption, a quick overview is useful, both as a reminder and as an introduction for those who might be still using GRUB Legacy or another boot manager, like the now discontinued LILO.

  • 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.
