How to Automatically Validate Android and iOS App Logic & File Structure in CI/CD
This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Validate App Integrity/Structure Scan in Mobile apps.
What is Appdome's App Integrity and Structure Scan?
The purpose of the App Integrity and Structure Scan is to authenticate the integrity of mobile apps and safeguard them against potential security threats. It aims to identify and neutralize attack vectors, such as unknown or malicious URLs, within the app. Additionally, the scan ensures that the app has not been altered or compromised with malicious elements.
How Does Appdome Implement the App Integrity and Structure Scan?
The App Integrity and Structure Scan is a key component of the Appdome Mobile Security Suite, automatically activated for every application uploaded to the Appdome platform. This scan meticulously reviews the app’s composition, data structure, data elements, and communication paths. Its primary focus is to assess and validate the structural integrity of mobile applications. This includes ensuring that the app is built and packaged correctly, and that its internal elements and communication pathways are secure and authentic.
Prerequisites for Using Appdome's App Integrity/Structure Scan Plugins:
To use Appdome’s mobile app security build system to Validate App Integrity/Structure Scan , you’ll need:
Appdome account (create a free Appdome account here)
A license for ONEShield™
Mobile App (.apk or .aab For Android or .ipa for iOS)
Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
How to Implement Validate App Integrity/Structure Scan in Mobile Apps Using Appdome
On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Validate App Integrity/Structure Scan without an SDK or gateway:
-
Designate the Mobile App to be protected.
-
Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
-
Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
-
App Integrity/Structure Scan is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
-
-
Select the defense: App Integrity/Structure Scan.
-
-
Follow the steps in Sections 2.2-2.2.2 of this article to add the App Integrity/Structure Scan feature to your Fusion Set via the Appdome Console.
-
When you select the App Integrity/Structure Scan you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains App Integrity/Structure Scan.
Figure 2: Fusion Set that displays the newly added App Integrity/Structure Scan protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory). -
Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below):
Figure 3: Fusion Set Detail Summary
-
Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:
-
Refer to the Appdome API Reference Guide for API building instructions.
-
Look for sample APIs in Appdome’s GitHub Repository.
-
Create and name the Fusion Set (security template) that will contain the App Integrity/Structure Scan feature as shown below:Figure 1: Fusion Set that will contain the App Integrity/Structure Scan feature
-
-
Add the App Integrity/Structure Scan feature to your security template.
-
Navigate to Build > Security tab > ONEShield™ section in the Appdome Console.
-
Toggle On > App Integrity/Structure Scan.

-
Congratulations! The App Integrity/Structure Scan protection is now added to the mobile app -
-
Certify the App Integrity/Structure Scan feature in Mobile Apps
After building App Integrity/Structure Scan, Appdome generates a Certified Secure™ certificate to guarantee that the App Integrity/Structure Scan protection has been added and is protecting the app. To verify that the App Integrity/Structure Scan protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
Figure 5: Certified Secure™ certificate
Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that App Integrity/Structure Scan has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that App Integrity/Structure Scan and other mobile app security features are in each build of the mobile app.
Using Threat-Events™ for App Integrity/Structure Scan Intelligence and Control in Mobile Apps
Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when App Integrity/Structure Scan is detected. To consume and use Threat-Events™ for App Integrity/Structure Scan in Mobile Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for App Integrity/Structure Scan shown below.
The specifications and options for Threat-Events™ for App Integrity/Structure Scan are:
Threat-Event™ Elements | Validate App Integrity/Structure Scan Method Detail |
---|---|
Appdome Feature Name | App Integrity/Structure Scan |
Threat-Event Mode | |
OFF, IN-APP DEFENSE | Appdome detects, defends and notifies user (standard OS dialog) using customizable messaging. |
ON, IN-APP DETECTION | Appdome detects the attack or threat and passes the event in a standard format to the app for processing (app chooses how and when to enforce). |
ON, IN-APP DEFENSE | Uses Appdome Enforce mode for any attack or threat and passes the event in a standard format to the app for processing (gather intel on attacks and threats without losing any protection). |

The following is a code sample for native Mobile apps, which uses all values in the specification above for App Integrity/Structure Scan:
Important! Replace all placeholder instances of <Context Key> with the specific name of your threat event context key across all language examples. This is crucial to ensure your code functions correctly with the intended event data. For example, The <Context Key> could be the message, externalID, OS Version, reason code, etc.

Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using App Integrity/Structure Scan. There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.
Releasing and Publishing Mobile Apps with App Integrity/Structure Scan
After successfully securing your app by using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
- Customizing, Configuring & Branding Secure Mobile Apps.
- Deploying/Publishing Secure mobile apps to Public or Private app stores.
- Releasing Secured Android & iOS Apps built on Appdome.
