I have a computer science background and want to break into defensive or offensive web testing. What are the key entry-level job roles in offensive security that focus primarily on hunting bugs in source code, and what tools should I master first?

With a computer science background, an Application Security Trainee or Junior AppSec Analyst role is your best target. These positions focus heavily on the OWASP Top 10 vulnerabilities, secure code reviews, and managing static and dynamic application security testing tools. You will be helping development teams identify flaws like SQL injection or cross-site scripting before the code goes to production. Master tools like Burp Suite, OWASP ZAP, and get familiar with code analysis platforms to build a strong portfolio.
Are you planning to build your own vulnerable web applications to practice finding exploits, or are you relying entirely on public capture the flag style challenges?
Focus on AppSec internships or junior analyst positions. Knowing how to read source code gives you a massive advantage over candidates who only know how to run network level scanners.
Totally agree. Modern infrastructure is shifting towards cloud and application layers, making code level understanding an incredibly valuable asset for any modern security testing team.
Building your own broken applications is actually a brilliant strategy, Mark. It teaches you the developer's mindset and the exact coding mistakes that introduce flaws. When interviewing for entry-level job roles in offensive security, explaining how you patched your own deliberate code errors looks incredible.
