The old port city has a long security tradition. OWASP Kerala was started in 2006 by a group of local professionals and has held seminars on cloud security, social engineering and mobile flaws. Then there is c0c0n, the security and hacking conference that has been staged in Kochi, including its 2018 edition at the Grand Hyatt.
For someone taking an online cyber security course from Fort Kochi, Mattancherry or anywhere across the backwaters, a c0c0n ticket is a chance to watch live demos, sit in on workshops and talk shop with people who do this for a living. GDG Cochin covers the developer side and runs DevFest Kochi every year. Bring your course projects along. Small meetups are where feedback comes fastest and where many local referrals start.
