DAST Basics
Main Ideas Behind Dynamic Testing
DAST checks running apps for security problems. It works like a hacker, trying to find weak spots from the outside. This method helps find real issues that attackers could use.
DAST vs. Other Security Tests
Here's how DAST compares to other tests:
Test Type
What It Does
When It's Used
DAST
Tests running apps from outside
During development and after launch
SAST
Checks source code
Early in development
IAST
Tests from inside the app
During development
RASP
Protects apps while they run
After launch
DAST stands out because it acts like a real attacker, making it key for app security.
Parts of a DAST System
A DAST system has three main parts:
- Scanner: Sends fake attacks to the app
- Analyzer: Checks how the app responds to attacks
- Reporter: Makes a list of found problems and how to fix them
These parts work together to find and report security issues in running apps.
How DAST Works
Planning Your DAST
Before starting DAST, make a plan:
- Pick which parts of your app to test
- Decide how often to test
- Choose what kinds of tests to run
Common tests include:
- Checking logins
- Making sure data input is safe
- Seeing how the app handles errors
Finding and Mapping
DAST starts by looking at all the ways someone could get into your app. This includes:
- Forms
- APIs
- Web addresses (URLs)
The DAST tool uses this info to test for weak spots.
Looking for Weak Spots
Next, the DAST tool tries to break into your app. It does this by:
- Sending bad data to your app
- Trying common hacking tricks
- Watching how your app responds
Testing Weak Spots
If the tool finds a possible problem, it checks to make sure it's real. Here's how:
- Sends many requests to the app
- Changes the data it sends each time
- Looks at how the app answers
- Figures out how big the problem is
Writing Up Results
After testing, you get a report. This report:
- Lists all the problems found
- Tells you how serious each problem is
- Gives tips on how to fix the issues
Your team can use this report to make your app safer.
