The InfoSecurity Challenge (TISC) is proudly organised by CSIT.

What is TISC? 

TISC is an online challenge organised by CSIT since 2020. It provides opportunities for interested Singaporeans to put their cybersecurity and programming skills to the test by solving challenging puzzles against the clock.

There will be a series of challenges for participants to complete, sequentially, in increasingly level of difficulty. The levels will cover various topics including, but not limited to, Web Pen-testing, Forensics, Reverse Engineering, Binary Exploitation, Cryptography, and Mobile Security.

TISC will be back in 2023! Stay tuned for updates on the challenge dates.
