What’s IAST?
• Interactive Application Security Testing
̶ Not quite DAST and not quite SAST
̶ “Behavioural analysis”
• Analyse an application in an instrumented environment and observe the behaviour to
detect potential vulnerabilities

Terminology
• SAST = Static Application Security Testing
• DAST = Dynamic Application Security Testing
• SDLC = Software Development Lifecycle
• ASoC = Application Security on Cloud
• Noise = findings that are not interesting
• False positive = False finding reported by the tool

Mobile Apps
• So… there’s more than 1 type of apps
Native Apps Hybrid apps Web view apps

6. 6 IBM Security
& Web ServicesMobile Apps
• Most web apps will have some form of business logic provided by a back end service

•Device Authentication
•Environment analysis
•Runtime protection

•Serve dynamic content
•Improves app rendering
•Basically a bookmark

Testing strategies: {sast}
• Native layer code can be handled with SAST
• Pros:
̶ Can run it shortly after building the app
̶ Fast (once you set it up)
̶ Could potentially test both the service and the app
• Cons:
̶ Takes a while to set up
̶ Doesn’ttake into account the platform
̶ Can’t keep up with the language updates
̶ Noise and false positives
̶ Not a lot of value for web view apps
Data Source Sink

8. 8 IBM Security
Testing strategies: {dast}
• Web services logic can be tested using DAST
• A running web service
• Test account
• Disable 3rd party security systems
• Access from the test system to the
app

9. 9 IBM Security
Testing strategies: {dast}
• Web services logic can be tested using DAST
• Pros:
̶ Can find vulnerabilities in the logic layer
̶ Language agnostic
̶ Can be automated without using the app
• Cons:
̶ You’re not actually testing the app
̶ Noise and false positives
̶ Not a lot of value for native apps

DAST Scanner

10. 10 IBM Security
Testing strategies: {iast}
• IAST will enable you to test both parts of the app at the same time
• Pros:
̶ Testthe app and some of the back end at the same time
̶ Easy to run (drag and drop)
̶ Can detected issues in the context of the platform being used
̶ Can be automated
• Cons:
̶ Complexlog-in mechanisms are hard to scan

Choosing the right one for you
• SAST : Difficult but works on both
• DAST : Fairly easy to set up, but only for web service
• IAST : Does a bit of both, very easy to use
• More “actionable” results
• Easier to understand
• Does a combination of both of the above
• Very easy to use

Statement of Good Security Practices: IT system security involves protecting systems and information through prevention, detection and response to improper access from within and outside your
enterprise. Improper access can result in information being altered, destroyed, misappropriated or misused or can result in damage to or misuse of your systems, including for use in attacks on others.
No IT system or product should be considered completely secure and no single product, service or security measure can be completely effective in preventing improper use or access. IBM systems,
