When I was 12, I was given a Raspberry Pi. For the first couple of days, it was really fun. After I had browsed the web for a while and played a bit of Minecraft, it sat in it’s box for a few months. I really had no idea what to do with it. That was until I discovered that I could build a website with it.
Do you use git to manage your site and or server files? In my opinion, this is undoubtably a good way to run things but you need to make sure it’s secure. Just try going to yoursite.com/.git/config. If you haven’t secured your server properly, you will see the configuration file for your git repository. Not good, huh? Not only could an attacker reveal lots of information about your code base including where the upstream server is, I believe they could possibly get the entire source. This would allow the attacker to see exactly how the site works and be able to exploit it very easily.
Now, the good news. It’s an easy fix!
Today, the guys at SubjectRefresh and I competed in the Cyber Centurion Security Challenge at The National Museum of Computing at Bletchley Park.
The day started with an introduction by the organisers and a brief explanation of how the day was going to work. Then it was off to the marquee to get started securing the machines we were provided with. There were two Windows VMs (server 2008 and 8.1) and one Ubuntu 14.04 image. The team delegated four people to work on the machines in the first part of the day and swapped out two at lunch time.
By the end, we’d managed to get 66% of the vulnerabilities on Ubuntu and about 80% on each of the Windows VMs. This result was on par with most of the other teams, the top 5 or so each having really close overall scores.

It was a fantastic day and we all had a lot of fun. To top it all off, we featured on the ITV Anglia news this evening! http://www.itv.com/news/anglia/update/2016-04-26/competition-aims-to-find-next-generation-of-cyber-defence-experts/
