  • Data encryption
  • SSL pin
  • Mobile App Local database encryption
  • Saving sensitive Mobile app data
  • App Sandboxing

Data encryption

Defining of protecting the local mobile data stored as part of the app. Define how the data will be encrypted. Focus on right solutions for data storage and securing the mobile app data

SSL pin

SSL certificates should be configured for manipulating network traffic. With SSL pinning when the app connects with a server, it compares the certificate with the pinned certificate. When there is a match, the server is trusted, and SSL connection gets established

Mobile App Local database encryption

Define the app local database protection by that how the apps offline data and entities should be protected by encryption mechanism

Saving sensitive Mobile app data

The application should follow the appropriate encryption mechanism for secure transfer/ save of application data.

Defining the use of secure keychain access to secure the app sensitive data e.g. user details in iOS platform.

App Sandboxing

App sandboxing is technique in iOS to ensure the security of the application data to ensure that application don’t share data with other applications installed on the same device.
