  • Network Security Rocky Linux/Centos/RHEL 8 - Unixcop

    Hardening network security devices minimize the risk of unauthorized access into a network’s infrastructure. Vulnerabilities in device management and configurations exploit weaknesses for a malicious cyber actor to exploit in order to gain presence and maintain persistence within a network.

    In addition to, Hackers have shifted their focus from exclusively exploiting traditional endpoints to increasingly exploiting specialized and devices, including routers and switches. They do this through common weaknesses in configurations, specific routing protocols, and implanting malware in the OS.

    So Ensure that all network security configurations are correct. Including static IP address assignments, DNS, WINS, whether or not to register a specific interface, binding order, and disabling settings on DMZ, 00B management, or backup networks. Also, check CSF configuration.

  • How to see grep output in color with highlighting feature

    The grep command is the de facto tool for searching text files. However, when there are too many matches, finding the requested text in the search results can be difficult. So grep comes with --color='auto' option. It surrounds the matching string with the colour, thus resulting in enhanced output.Now you know grep can color-highlighting the matched text or words in its output. However, by default, that option is turned off. So let us see how to colorized grep by default for viewing the entire file with highlighted matches on Linux or Unix-like systems.

  • How to use Keybase to encrypt files on Linux

    Keybase is an end-to-end encryption tool for messaging and for file sharing. It’s an excellent, easy-to-use tool for those that want to quickly encrypt and share files with friends. Here’s how to do it on Linux.

  • Improve The CrowdSec Multi-Server Installation With HTTPS Between Agents | Linux Journal

    To address security issues posed by clear http communication in our previous crowdsec multi-server installation, we propose solutions to achieve communication between Crowdsec agents over encrypted channels. On top of that, the third solution allows server-2 or server-3 to trust server-1 identity, and avoid man-in -the -middle attacks.

  • What is Metasploit Used For

    A Metasploit framework is a sophisticated tool that cybercriminals and hackers can use to investigate systemic vulnerabilities on web servers. It can be simply modified and utilized with many operating systems since it is an open-source framework. It also includes tools for automatically comparing a program’s security vulnerabilities to its patched (repaired) version. It also includes anti-forensic and strong evasion features.

  • Linux Fu: User Space File Systems — Now For Windows, Too! | Hackaday [Ed: Better just use the real thing -- without NSA back doors and recurring data losses]

    One of the nice things about the Unix philosophy that Linux inherited is that the filesystem is very modular. That’s good, too, because a typical system might want a choice of filesystems like ext4, reiserfs, btrfs, and even network systems like nfs. Besides that, there are fake file systems like /sys and /dev that help Linux make everything look like a file. The downside is that building a filesystem required changing the kernel or, at least, writing a loadable module. That’s not as hard as it sounds, but it is a little more difficult than writing a normal program. Then came FUSE — file system in user space. This is a single file system module that allows you to create new file systems by writing ordinary code.

  • How to Take Screenshots on a Chromebook - Make Tech Easier

    The process of taking screenshots on a Chromebook may be different from doing it on a Windows PC or a Mac – but not drastically different. You may be a little unsure how to do this in Chrome OS, as even the best of them don’t have a Print screen key, but it’s fairly simple to learn. Whether you want to grab a portion of the screen or the entire thing, there are multiple ways to take screenshots on a Chromebook.

  • Yet another gremlin: the zero-width space

    The gremlin detector script in A Data Cleaner's Cookbook now looks for zero width spaces (U+200B, hex e2 80 8b, ​).

    Like a soft hyphen (SHY), a zero-width space (ZWSP) is usually non-printing and invisible, and indicates for a Web browser or word-processing program where a string of visible characters can be broken when wrapping a line. With SHY, the program will add a hyphen at the end of the wrapped line, while a ZWSP just means "You can break the string here when wrapping".

    Also like a SHY (and a no-break space (NBSP)), a ZWSP can cause problems where it isn't needed. A quick googling for "problem with zero width space" turned up ZWSP-caused issues with

  • 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.
