What does hacking really look like – and how do attackers actually break into systems? In this video, I sit down with Casey Erdmann, Red Team Engineer and author of Red Team Engineering, to pull back the curtain on how real-world cyberattacks work, what cybersecurity is actually like to learn, and what most people get completely wrong about hacking.
CrowdSec is a service that aims to enhance the security of your Linux server – which it does in a very interesting way. Leveraging the power of the very “crowd” it serves, CrowSec is able to build intelligence that benefits every server that has it installed. This service has been discussed on the channel before, but in this tutorial you’ll see some of the new features as of CrowdSec 1.5.
OpenSSH is a fantastic tool for remotely managing Linux servers, but with great power comes great responsibility! If a threat actor is able to gain access to OpenSSH on your Linux server, then they have full access to cause all kinds of mischief. In this video, Jay goes over 5 must-have tweaks to strengthen the security of OpenSSH on your server.
Thanks to Linode for sponsoring this video. Support LearnLinuxTV and spin up your very own Linux server by checking out their awesome cloud platform.
CrowdSec is an Intrusion Prevention System that does things a bit differently than other IPS solutions. It’s collaborative, and open-source. CrowdSec has been featured on LearnLinuxTV a few times in the past, but in this video we’ll explore the CrowdSec Console, which allows you to monitor the security events of your Linux servers from an impressive web dashboard. In this video, we’ll get an overview and see it in action!
Note: This is not a review, but an overview of a security solution that Learn Linux TV is actually using in real-life.
When you need to run Linux commands with elevated privileges, sudo is the tried and true method to run commands as another user (such as root). In this introductory tutorial, we’ll take a look at some of the inner-workings of sudo.
In various tutorials throughout the history of LearnLinuxTV, we’ve gone over the importance of using public keys with OpenSSH. But what do you do when you have multiple clients you work with, how do you manage keys between them? In this video, we’ll go through an example scenario where we have three clients, and we need to maintain multiple SSH keys for each.
TheLog4Shell vulnerability is taking the Internet by storm, and it’s already being used for real-world attacks. In this video, Jay discusses the details around Log4Shell vulnerability in Log4j, and also CrowdSec’s community-based response to the situation.
CrowdSec is a cutting-edge security solution for your Linux servers. As an intrusion prevention system, its goal is to stop unauthorized access and prevent attacks. But unlike other IPS solutions, it does it a different way – by using knowledge as power. CrowdSec was covered on this channel before, but in this video, you’ll see an updated look complete with an overview of how to set up protection for WordPress as well.
CrowdSec is a solution that aims to help protect your Linux servers, and its approach is quite different than other solutions. CrowdSec is able to utilize reputation to make intelligent decisions, and is able to be extended to meet your needs. In this video, I take a first look at CrowdSec – I’ll show you the installation process and also an example scenario so you can see it in action.
