Capture The Flag (CTF) Challenges.
Capture The Flag (CTF) Challenges.
CTF Challenge is a kind
of hackthon that mainly assaying the practical and logical skills of Ethical
Hacking. It consists of a series of challenges that vary in their degree of
difficulty, and that require participants to exercise different skill sets to
solve. Once an individual challenge is solved, a “flag” is given to the player
to earn points. Players can be individuals who attempt the various challenges
by themselves, or they can work with others to attempt to score the highest
number of points as a team competitively.
There are two main types
of CTF challenges.
- Jeopardy-Style CTFs
- Attack-Defence CTFs
Jeopardy-Style CTFs
consist of completing different challenges from a board range of categories in
order to earn points/flags in a limited time. They preserve a leader board
usually to figure out the winner of the entire competition. Some of the
challenges are based on a story line like a murder or a crime.
Attack-Defense CTFs
consist of two teams, one team who defense a network or server, and another who
attacks it. Most probably they this type CTFs are knock out because of the
large number of competitors. 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.
Every challenge is a combination of multiple domains in
information/cyber-security:
- Penetration testing
- Cryptography
- Steganography
- Computer Forensics
- Wireless Penetration
- Programming
- Reverse engineering
- Exploitation
- Traditional attacks such as
xSS, SQL Injections etc. & many more…
Sri Lanka has two
popular annual CTF Challenges that organized by two cyber security degree
holders for inter-university students. CyberFest is organized by the NationalInstitute of Business Management (NIBM). And the other one, CodeFest CTF
Challenge is organized by the Sri Lanka Institute of InformationTechnology(SLIIT). Both of them are Jeopardy-Style CTF Challenges. Most of the
university students of Sri Lanka those who reads Computer Science major,
compete for those challenges as three or four people teams.
I have already participated for the CodeFest CTF challenge and Cyberfest last year(2018) with my team. Our team '7R4C3R' won merit certificate in the Codefest CTF challenge.

CTF Challenges are
organized to improve the practical knowledge of the Cyber-Security and
Information Security and the skills of Ethical Hacking. You only have to know
the technologies that linked up with them. Basic knowledge of networking and virtualization
also needed for these competitions. If you are a beginner or an expert in
information/cyber security competing for a CTF Challenge will be a very exiting
and an enjoyable experience for your career.
