Learn 3 Easy Steps to Use Secure Certificate Pinning to prevent MiTM Attacks in Android and iOS apps. Validate server certificates for TLS sessions.
Certificate Pinning is the process of embedding a mobile app with valid SSL certificate for trusted servers. An application which pins a certificate or public key no longer depends on external elements – (such as DNS or intermediate/public certificate authorities) – when making security decisions relating to a peer server’s identity. In mobile, the most common form of certificate pinning is embedding the server certificates inside the mobile app to ensure that the server certificate is always trusted. This will prevent hackers from presenting modified fraudulent certificates to the mobile app in an attempt to redirect the mobile user to a malicious site.
A host or service’s certificate or public key can be added to an application at development time, or it can be added upon first encountering the certificate or public key. The former – adding at development time – is preferred since preloading the certificate or public key out of band means the attacker cannot taint the pin by intercepting the session before the TLS handshake completes.
This KB describes step by step instructions to implement Secure Certificate Pinning in any iOS and Android apps without any coding.
Appdome’s Secure Certificate Pinning automatically performs certificate validation by verifying the authenticity of the SSL/TLS certificates received from the server. This first occurs during the initial secure communication exchange (ie: the TLS/SSL handshake) between the app and a server.
Appdome enables developers to verify and pin certificates for specific domains in different methods. Each Service Domain can be configured using * as a wildcard value to impact multiple domains.
Below are the Certificate Pinning Schemes that can be configured using Appdome.
Appdome offers the following 3 mutually exclusive options (pinning profiles) to implement Secure Certificate Pinning in any iOS or Android app:
When you enable Appdome’s optional Protect Service Domains Only setting, Appdome will perform certificate validation only on the Service Domains that you specify. All other domains will not be inspected or validated. This provides you maximum flexibility to control the security posture of your app.
Please follow these 3 easy steps to add Secure Certificate Pinning to any iOS and Android app using Appdome.
Congratulations! You now have a mobile app secured with Certificate Pinning.
Appdome’s no-code mobile app security platform offers mobile developers, DevSec and security professionals a convenient and reliable way to protect Android and iOS apps with Secure Certificate Pinning. When an Appdome user clicks “Build My App,” Appdome leverages a microservice architecture filled with 1000s of security plugins, and an adaptive code generation engine that matches the correct required plugins to the development environment, frameworks, and methods in each app.
