How to become a Cybersecurity / AppSec Engineer
Find and fix what attackers would exploit: networking, systems, web vulnerabilities and secure development.
Best for
Students who are curious about how things break, enjoy depth, and are patient enough to learn systems thoroughly.
Maybe not for you if
Anyone looking for a quick route in. Security is typically a harder FIRST job than development. Many practitioners arrive after a development, ops or support role, and fresher openings are fewer.
The 4 phases
What each phase gets you to. The steps, resources and checkpoint inside each one open with a free account.
Phase 1 - Systems and networking foundations
6-8 weeksGoal: Explain, at packet and process level, what happens when a browser logs into a server, and harden the host that server runs on.
4 steps · ends in a scored checkpoint (65% to clear) · assumes basic programming
Phase 2 - Build before you break
6-8 weeksGoal: Ship a real web application with authentication you wrote yourself, then produce a threat model that names exactly where you would attack it.
4 steps · ends in a build deliverable
Phase 3 - Vulnerabilities and secure development
7-9 weeksGoal: Exploit and then correctly fix the main web vulnerability classes on systems you are authorised to test, and prove the fixes hold in a pipeline.
5 steps · ends in a scored checkpoint (70% to clear)
Phase 4 - Clear the process
5-7 weeksGoal: Pass the coding, aptitude and security rounds, and be ready for the SOC-shaped job that most fresher security offers actually are.

What hiring actually looks like here
Security is commonly reported among the most in-demand areas, but dedicated fresher openings are typically fewer than in development. Where they do exist in India they are most often L1 SOC analyst seats in managed-services firms, often on rotating shifts. AppSec and penetration testing titles usually arrive a year or two later, and a common route is to enter as a developer or ops engineer and specialise once you understand systems from the inside.
