Your roadmap to real skills.
Many tracks and dozens of sub-tracks. Every track starts with a free intro lesson.

Many tracks and dozens of sub-tracks. Every track starts with a free intro lesson.
What is Application Security?
Understand why applications are a major attack target and where security fits in the SDLC.
OWASP Top 10
Walk through the OWASP Top 10 with real-world examples and identify vulnerabilities in sample code.
Input Validation and Injection Attacks
Understand SQL injection, XSS, and command injection through hands-on CTF challenges.
Authentication and Session Security in Applications
Learn cookie security and intercept requests with BurpSuite to observe session vulnerabilities.
Secure Coding Practices
Apply input sanitization, safe error handling, and supply chain security to real code.
Web Application Firewalls and Security Testing
Understand WAFs, SAST vs DAST, and analyze HTTP traffic with browser DevTools.
Hands-on: OWASP Top 10 in DVWA and WebGoat
Stand up DVWA and WebGoat in Docker and exploit then patch at least four OWASP Top 10 categories.
OWASP A01: Broken Access Control
Find and fix IDOR and privilege-escalation flaws with server-side ownership and role checks.
OWASP A02: Cryptographic Failures and Password Hashing
Store passwords correctly with salted bcrypt/Argon2 and understand why MD5/SHA-1 are broken for security.
OWASP A04: Insecure Design
Distinguish design flaws from code bugs and prevent them with threat modeling and abuse cases.
OWASP A05: Security Misconfiguration
Find default credentials, exposed storage, and missing headers, then harden by default.
OWASP A06: Vulnerable and Outdated Components
Inventory dependencies, find known CVEs, and automate updates to prevent an Equifax-style breach.
OWASP A08: Software and Data Integrity Failures
Verify the integrity of dependencies, pipelines, and data, and avoid insecure deserialization.
OWASP A09: Security Logging and Monitoring Failures
Log the right security events, centralize and alert on them, and tie alerts to incident response.
OWASP A10: Server-Side Request Forgery (SSRF)
Exploit and patch SSRF with URL allow-lists, internal-range blocking, IMDSv2, and least-privilege IAM.
Top Security Threats and the Frameworks That Map Them
Map ransomware, supply-chain, zero-day, phishing, and insider threats to OWASP and the NIST CSF.
Security Best Practices for Developers
Apply defense in depth, least privilege, secure by default, input validation, secrets management, and review checklists.
Security Code Review
Read JavaScript, Python, and SQL code by pattern-matching insecure patterns; pair with Semgrep to scale.
Bug Bounty Programs
Operate inside HackerOne and Bugcrowd scope rules and write a professional vulnerability disclosure report.
Application Security Resources and Next Steps
Explore curated resources, certifications (PenTest+, BSCP, GWEB, OSWE), and practice platforms.
Application Security Job Readiness
Translate AppSec skills into a resume, portfolio plan, and interview prep for AppSec engineer roles.
