Breaking Into AppSec: Hack Your Way Into Cybersecurity!
Getting Started in Application Security: A Beginner’s Guide
Introduction
Breaking into Application Security (AppSec) can seem daunting, but it’s one of the most exciting and dynamic fields in cybersecurity. Whether you’re transitioning from software engineering, product management, or just starting your journey in tech, there’s a clear path to enter AppSec—and we’re here to help you get started.
This guide will walk you through what AppSec is, the skills you'll need, how to build them, and how to position yourself for landing that first role.
What is Application Security?
AppSec is a discipline within cybersecurity that ensures applications are built and deployed securely. AppSec engineers partner with developers to review code, perform penetration tests, and embed secure practices into product development.
Responsibilities may include:
- Secure Code Review: Spotting vulnerabilities like SQLi, XSS, etc.
- Threat Modeling: Predicting how systems might be attacked and assessing risks.
- Penetration Testing: Simulating real-world attacks, with both black box and white box approaches.
Building an AppSec Skillset
You’ll need a strong foundation across three areas:
1. Software Development
- Learn languages like Python, JavaScript, or Go.
- Understand the SDLC (Software Development Lifecycle), CI/CD, and static analysis.
- Recommended resources: CS50, Khan Academy
2. Networking & OS Fundamentals
- Basics of TCP/IP, Linux security, and cloud environments.
- TryHackMe’s Network Fundamentals is a great place to start.
3. AppSec Core Concepts
- Study the OWASP Top 10, CSRF, CSP, authentication, and cryptography.
- Practice with:
- Books: The Tangled Web, Web Application Hacker’s Handbook
Breaking Into the Industry
1. Contribute to Open Source
- Projects like Semgrep, Nuclei, and OWASP need contributors.
- Showcase your work on platforms like Hacker News or Lobste.rs.
2. Try Bug Bounties
- Start with programs like HackerOne’s DoD Program.
- Learn real-world skills and build credibility—even unpaid reports build experience.
3. Attend Conferences & Meetups
- Events: DefCon, BlackHat, BSidesSF, DevSecCon, OWASP Global AppSec.
- Join communities: OWASP Slack, Mastodon, local DefCon meetups.
4. Get Certified (Optional)
- CompTIA Security+: best entry-level cert
- OSWE: advanced web application exploitation
- Burp Suite Certified Practitioner
