In Part 1 of this tutorial, you learned how to set up a log relay server that uses mTLS to securely receive logs from only specifically registered devices and forward them to a SIEM like Wazuh.

In this, Part 2 of the tutorial, you'll learn how to configure agents (or clients) to authenticate themselves to that log relay and send their logs securely to the SIEM server.

A SIEM (Security Information and Event Management) tool like Wazuh is only as good as the logs it ingests. It's important to gather useful information from your critical assets, and endpoints are some of the most important assets we manage. But how do you gather logs from those devices when they're constantly moving around?

Hey, Ubuntu users! If you haven't encrypted your hard drive, you should! An unencrypted hard drive makes it easy for someone to compromise your system when it's left unattended. With a few minutes of physical access to even a locked computer, an attacker (or prankster) could gain access to your sensitive files.

If you're using your computer for work, you should be even more careful to protect the information on your computer. In this tutorial, we'll cover how to encrypt your hard drive.

Does knowing how to commit crime make you better at detecting it? If you've heard stories of individuals like Frank Abagnale, who committed massive fraud and stole millions of dollars and was later contracted as a consultant for the U.S. government, you may be inclined to say: "Yes!" But not everyone would agree...

Almost anyone who listens to the news or watches movies these days has heard the term hacking. For many, it evokes images of hoodie-clad criminals with fingerless gloves - furiously scanning through dark screens of green text in search of hidden secrets. But what about the hackers who aren't criminals and don't wear hoodies?

You may have heard of so-called ethical hackers... But what makes them different? And how clear is the line between them and 'the bad guys'?

Hint: It's not as clear as you might think 😉...

The internet is built on layers upon layers of abstraction. This makes it possible for an immense variety of people and machines to communicate with one another. I want to share some ways I've used abstraction to help me get better results from artifical intelligence (AI).
