How to Use Secure TLS Cipher Suites in Mobile Apps Using AI

Last updated March 12, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Enforce TLS Cipher Suites in Mobile apps.

What Is TLS Cipher Suite Enforcement?

Enforcing specific SSL/TLS cipher suites in Android and iOS apps ensures secure, encrypted communication between the app and backend servers. By specifying modern suites like AES-256 and ECDHE, apps exclude older, vulnerable suites, such as RC4 and DES, which are susceptible to attacks. On Android, developers can enforce secure cipher suites via OkHttp or HttpsURLConnection, while iOS uses NSURLSession for the same purpose. This protection is essential to secure data transmissions, such as login credentials and transaction information, and is required for compliance with industry standards like PCI DSS to protect against man-in-the-middle attacks and encryption downgrades.

How Appdome Protects Mobile Apps With TLS Cipher Suite Enforcement?

Appdome’s dynamic Enforce Cipher Suites plugin scrutinizes the connections established by mobile apps, identifying and blocking any that were made using non-approved cipher specifications. By doing so, it acts as a safeguard, treating such connections as compromised and preventing potential security breaches. Mobile developers can leverage Appdome’s Threat-Events™ to collect detailed data on cipher suites and tailor in-app responses based on detected threats. Note: Enforcing cipher suites should only be done for domains located in your network and under your control. Any use outside such domains is strongly inadvisable due to the very high likelihood of MiTM violation in such cases.

Prerequisites for Using Appdome's Enforce Cipher Suites Plugins:

To use Appdome’s mobile app security build system to Enforce TLS Cipher Suites , you’ll need:

Appdome account (create a free Appdome account here)
A license for Enforce Cipher Suites
Mobile App (.ipa for iOS, or .apk or .aab for Android)
Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)

How to Implement Enforce TLS Cipher Suites in Mobile Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Enforce TLS Cipher Suites without an SDK or gateway:

Designate the Mobile App to be protected.
1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
2. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
3. Enforce Cipher Suites is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
Select the defense: Enforce Cipher Suites.

Create and name the Fusion Set (security template) that will contain the Enforce Cipher Suites feature as shown below:

Figure 1: Fusion Set that will contain the Enforce Cipher Suites feature

Follow the steps in Sections 2.2-2.2.2 of this article to add the Enforce Cipher Suites feature to your Fusion Set via the Appdome Console.

When you enable Prevent MiTM Attacks you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Enforce Cipher Suites.

Figure 2: Fusion Set that displays the newly added Enforce Cipher Suites 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.

Add the Enforce Cipher Suites feature to your security template.

Navigate to Build > Security tab > Secure Communication section in the Appdome Console.
Like all other options in ONEShield™, Enforce Cipher Suites is turned on by default, as shown below:
Figure 4: Selecting Enforce Cipher Suites
Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

Toggle On Prevent MiTM Attacks > Enforce Cipher Suites.

(a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Enforce Cipher Suites as shown below.

(b) To receive mobile Threat Monitoring, check the ThreatScope™ box as shown below. For more details, see our knowledge base article on ThreatScope™ Mobile XDR.

Figure 4: Selecting Enforce TLS Cipher Suites
Note: The Appdome Platform displays the Mobile Operation Systems supported by each defense in real-time. For more details, see our OS Support Policy KB.

Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Enforce Cipher Suites:

Threat-Events™ OFF > In-App Defense
If the Threat-Events™ setting is not selected. Appdome will detect and defend the user and app by enforcing TLS Cipher Suites.

Threat-Events™ ON > In-App Detection
When this setting is used, Appdome detects the use of non-approved cipher suites and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing, enforcement, and user notification. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ to Enforce Enforce Cipher Suites Intelligence and Control in Mobile Apps.

Threat-Events™ ON > In-App Defense
When this setting is used, Appdome detects and defends against TLS Cipher Suites (same as Appdome Enforce) and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Enforce Enforce Cipher Suites Intelligence and Control in Mobile Apps.

Configure the User Experience Options for Enforce Cipher Suites:
With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.

App Compromise Notification: Customize the pop-up or toast Appdome uses to notify the user when a threat is present while using the protected mobile app.

Short message Option. This is available for mobile devices that allow a banner notification for security events.

Localized Message Option. Allows Appdome users to support global languages in security notifications.

Figure 5: Default User Experience Options for Appdome’s TLS Cipher Suites

Enforce Cipher Suites Threat Code™. Appdome uses AI/ML to generate a unique code each time Enforce Cipher Suites is triggered by an active threat on the mobile device. Use the code in Appdome Threat Resolution Center™ to help end users identify, find and resolve active threats on the personal mobile devices.

Extra Configuration with Enforce Cipher Suites:
Creating a Cipher Suites List File
To ensure secure communication between your app and its servers, attach a .txt file containing the list of supported cipher suites. This file helps define the encryption protocols your servers will use. Format: Each cipher suite should be listed on a separate line. Use the standard naming conventions (e.g., TLS_RSA_WITH_AES_256_CBC_SHA). Ensure the list matches the configurations supported by your servers.

Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.

Congratulations! The Enforce Cipher Suites protection is now added to the mobile app

Certify the Enforce Cipher Suites feature in Mobile Apps

After building Enforce Cipher Suites, Appdome generates a Certified Secure™ certificate to guarantee that the Enforce Cipher Suites protection has been added and is protecting the app. To verify that the Enforce Cipher Suites protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:

Figure 6: 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 Enforce Cipher Suites has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Enforce Cipher Suites and other mobile app security features are in each build of the mobile app.

Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using Enforce Cipher Suites. 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 Enforce Cipher Suites

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.

Frequently Asked Questions

Why aren’t SHA1 ciphers supported by default?

Due to security concerns, SHA1 ciphers are considered unprotected and are not supported by default. This is to prevent the use of weaker encryption methods.

What are the supported cipher suites for Android and iOS apps?

Supported cipher suites for both Android and iOS apps using TLS 1.2 and TLS 1.3, including various configurations of AES and CHACHA20 suites, among others.
