  • Day 9

    We started the day with an intensive lab. We focused on the IAAA model, which stands for Identification, Authentication, Authorization, and Accounting. This model describes the fundamental steps to secure access to a system: Accounting: Tracking and recording the user’s activities while accessing resources, often for auditing purposes. Identification: The process of recognizing a user…

  • Day 8

    Today’s subject was firewalls, with an introduction to Snort and writing rules for packet inspection. We took a deep dive into Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS), which are essential for detecting and preventing security threats on a network. One key topic we explored was the difference between false positives and false…

  • Day 7

    The long-awaited lesson on cryptography has finally arrived – Cryptography! I had hoped to avoid too much math, and luckily, I got my wish. While we covered some basic algorithms, we didn’t dive too deep into complex topics. One concept I was particularly nervous about was Diffie-Hellman—the key exchange protocol—but surprisingly, it wasn’t as difficult…

  • Day 6

    This week, we took our first steps into the world of Security Information and Event Management (SIEMs). To lay a strong foundation, we dove into various concepts in defensive security, including Intrusion Detection Systems (IDS), Intrusion Prevention Systems (IPS), and Data Loss Prevention (DLP). These concepts help organizations monitor, detect, and prevent security breaches, safeguarding…

  • Day 5

    We kicked off the day with our usual Kahoot, then dove straight into our first assessment. I got all of the questions right and overall it went well for all of us so we’re off to a good start. After that, we covered key security principles, like the CIA triad. It really feels like we’re…

  • Day 4

    I honestly don’t even know where to begin. Today was packed with material! We started off by reviewing Wireshark and then jumped into our daily Kahoot session to go over yesterday’s material. The morning was focused on system administration and Linux. It became clear that the two go hand in hand—you can’t really have one…

  • Day 3

    Today kicked off with a quick revision of the OSI model before diving straight into networking protocols. We got hands-on experience with some labs, which made the content much easier to grasp. It was an intense day, packed with new concepts ranging from SNMP fundamentals to getting familiar with Wireshark. I completed two labs—one as…

  • Day 2

    Picking Up the Pace Today was Day 2, and as expected, things got a little more intense. The pace is picking up, and we’re diving deeper into networking concepts. Fortunately, a lot of the material we covered today was familiar to me from my CompTIA Network+ and CCNA studies. I’ve been studying networking on and…

  • Day 1

    Today marked the first official day of my cybersecurity bootcamp at Ironhack, and it was an exciting start! We kicked off early at 8 AM (UTC/GMT) with an introduction to the course and an onboarding session, going over some details we had already touched on during Day 0. One of the highlights of the morning…

  • Day 0 – Introduction to the course

    Today marked the official start of my cybersecurity bootcamp at Ironhack! The day began with a small introduction, where we got an overview of what to expect in the coming weeks. The instructors set some ground rules, emphasising that we are expected to put in additional work outside of class hours. We will be working…
