  • Build your career in Computer Forensics: List of Digital Forensic Tools - Part I

    Digital devices are present everywhere and considered to be the primary source of evidence in the case of cybercrime. Out of all the devices, phones and laptops are the top weapons used in cybercrimes. Regardless of who the device belonged to, either the victim or suspect, it offers an abundance of data to investigate the crime. But retrieving evidence from these devices in a secure environment can be very challenging. To overcome the time constraint and other complications, cyber forensic professionals use digital forensic tools.  

  • What are Open Source Security Approaches? With Examples

    Open source security approaches enable organizations to secure their applications and networks while avoiding expensive proprietary security offerings. 

    An open source approach allows organizations to secure their applications across cloud providers and other platforms using platform-agnostic APIs. These APIs are written by contributors to the open source software code while cloud providers may use open source code that allows the open APIs to connect to the cloud.

    Open source approaches, for security or not, also bring in collaboration across an industry. It isn’t just one organization that benefits from a program or technology, but everyone who contributes to and uses it.

    The open source projects and programs used as examples in this article come from two major open source entities: The Linux Foundation and the Cloud Native Computing Foundation (CNCF). The two also work closely together to further the projects under their purview.

  • Cloud Snooper: Hackers Using Linux Kernel Driver To Attack Cloud Server [Ed: So, if you install malicious software in Linux, due to recklessness or sabotage, it'll do malicious things. How is that a Linux weakness?]

    Whether you’re a Linux user or not, you must have heard the buzzword about the Linux — “Best OS for security.” Well, it is true, but being a computer program, Linux also has some downside that challenges its security.

    Talking about the security risks, recently, SophosLab published a report about a new malware dubbed Cloud Snooper, that can compromise the security of any Linux or other OS based servers by deploying a kernel driver.

  • IPFire on AWS: Update to IPFire 2.25 - Core Update 141

    Today, we have updated IPFire on AWS to IPFire 2.25 - Core Update 141 - the latest official release of IPFire.

    Since IPFire is available on AWS, we are gaining more and more users who are securing their cloud infrastructure behind an easy to configure, yet fast and secure firewall.

    This update adds the rewritten DNS stack and brings many bug fixes to the cloud.

  • The “Cloud Snooper” malware that sneaks into your Linux servers [Ed: Sophos citing itself, hyping up the threat is installing malicious software on one's own server]

    SophosLabs has just published a detailed report about a malware attack dubbed Cloud Snooper.

    The reason for the name is not so much that the attack is cloud-specific (the technique could be used against pretty much any server, wherever it’s hosted), but that it’s a sneaky way for cybercrooks to open up your server to the cloud, in ways you very definitely don’t want, “from the inside out”.

    The Cloud Snooper report covers a whole raft of related malware samples that our researchers found deployed in combination.

OpenSMTPD

  • OpenSMTPD Email Server Vulnerability Threatens Many Linux and BSD Systems [Ed: It is this package, not the operating systems (GNU/Linux rarely uses this)]

    A critical vulnerability has been discovered in the OpenBSD email server OpenSMTPD. Exploiting the flaw could allow remote code execution attacks. The seriousness of the vulnerability poses a threat to the integrity of OpenBSD and Linux systems.

  • 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.
