What is the OWASP Top 10?

The OWASP Top 10 is a regularly updated list of the most critical web application security risks, such as injection, broken access control, and XSS.

What is the difference between SAST and DAST?

SAST analyzes source code statically for flaws, while DAST tests a running application dynamically by probing it like an attacker.

🔐 Application Security & Pentesting

Application security (AppSec) protects software from vulnerabilities, and penetration testing actively probes for them. This visual guide covers the OWASP Top 10, secure coding, threat modeling, SAST/DAST, and the pentesting process.

Slide 1 / 20

What Is AppSec?

Protecting applications from security vulnerabilities.

Slide 2 / 20

What Is Pentesting?

Actively probing an app for exploitable flaws.

Injection (SQL etc.)

Untrusted input running as commands.

Slide 5 / 20

Broken Authentication

Weak login and session management.
