Capture the Flag (CTF)
is a computer security competition. This kind of contests are usually designed to serve as an educational exercise to give participants experience in securing a machine, as well as conducting and reacting to the sort of attacks found in the real world. Reverse-engineering, network sniffing, protocol analysis, system administration, programming, and cryptanalysis are all skills which have been required in prior competitions. There are two main styles of capture the flag competitions: attack/defense and jeopardy.
In an attack/defense style competition, each team is given a machine (or small network) to defend on an isolated network. Teams are scored on both their success in defending their assigned machine and on their success in attacking other team’s machines. Depending on the nature of the particular CTF game, teams may either be attempting to take an opponent’s flag from their machine or teams may be attempting to plant their own flag on their opponent’s machine. One of the more prominent attack/defense CTFs is held every year at the well known hacker conference DefCamp where this activity is much expected every time.
It’s all about teamwork, eyes wide open and remarkable skills.
Every time it spreads the newest security techniques and supports measuring the security skills of the teams. A complete team covering all the main skills is always the best option to get into the finals.
In the same time the competition does strengthen both technical and management skills; the leader is coordinating everything, every step from the process making sure that the team is following the line to capture the flag. Everything is doubled with mystery, mathematics and complicated algorithms to make everything even more challenging.
Some consider this competition as a game, because originally it was a game that simulate small team combat, based on defending an immobile flag while trying to capture the flag of the other team. What was the most important? Having the proper team and knowing the proper techniques to achieve the goal. Of course everything is doubled by:
- team coordination
- 48 hours of intensive work
- Gaining knowledge
- Simulating a live experiment
- Facing challenges
- Cash and/or an awesome experience
What you should also take into account is the fact that once you enter D-CTF you’ll never want to go back! Yes, it’s addictive and you’ll always want to come back. This is why every year, DefCamp brings together so many strong teams, skilled teams, passionate teams that are always ready to take over the world. What does that mean? Embrace the challenge, solve the exercises, get the flags and of course to take all our money – the cash prizes, of course!
started back in 2011 as a small infosec gathering among friends. Soon, the meetup became an event and, later on, the largest and most important cybersecurity and hacking conference from Central and Eastern Europe. In 2019 it celebrated the 10th edition with over 2000 security experts, developers, decision makers, entrepreneurs, members of the academia and private and public sectors from all around the world.
Cyber Security Research Center from Romania (CCSIR) is a Non-Governmental Organization with the sole purpose of promoting, supporting, implementation and coordination of security research in the information security field in Romania, as well as international actions with short, medium and long term partnerships in the information security arena.
