Welcome back to my blog, friends! My name is Ash and I’m a 27-year-old cybersecurity enthusiast. On this blog, we explore various topics related to hacking, capture the flag events, and the journey to becoming a cybersecurity professional.

Today, I want to talk about day 22 of the Advent of Cyber Tryhackme Challenge. If you’re new to the blog, the Advent of Cyber challenge is a 24-day event that covers a variety of cybersecurity topics. Each day, a new challenge is released, and I’ll be going over the walkthroughs and providing tips and tricks on how to complete them.

I have to admit, I’m feeling a bit behind on the challenges as today is December 25th in Australia and the challenges are released at midnight. But, I wanted to take a moment to talk about one of the topics covered in day 22: attack surface reduction.

Attack surface reduction is all about improving the security posture of a network by learning from recent attempts to disrupt it. It’s a low-effort, high-value change that can significantly improve the security of a network.

So, what exactly is an attack vector? In cybersecurity, an attack vector is a tool, technique, or method used to attack a computer system or network. It’s the weapon that an attacker uses to gain access to a system or network. Some examples of attack vectors include phishing emails, denial of service attacks, and unpatched vulnerability exploitation.

The attack surface is the surface area of a victim that can be impacted by an attack vector and cause damage. In cybersecurity, this can include email servers, web servers, and end-user machines that can be manipulated by an attacker.

The goal of attack surface reduction is to minimize the attack surface as much as possible. This can be done by implementing security measures such as firewalls, intrusion detection systems, and patch management. However, it’s important to remember that the attack surface can never be eliminated completely, but it can be reduced to make it more difficult for attackers to gain access.

In summary, attack surface reduction is an important concept in cybersecurity as it helps improve the security posture of a network. By understanding attack vectors and the attack surface, we can implement security measures that make it more difficult for attackers to gain access and cause damage.

I hope you found this information helpful. Remember to check out the video walkthrough for day 22 of the Advent of Cyber challenge and to visit the description for more details and links. Thanks for tuning in and stay safe out there!
