It allows an app to encrypt and decrypt the files stored in their app directory. Data Protection APIĪll iOS versions since iOS 4 have a built-in security feature called Data Protection.

Also, memory pages are marked as non-executable with ARM’s Execute Never (XN) feature to stop malicious code from being executed. This makes the exploitation of memory-corruption-bugs much less likely. Address space layout randomization (ASLR) randomizes the assigned memory regions for each app on every startup. They run in their own address space and get controlled by the OS.Īdditionally, iOS has methods to prevent memory-related security bugs. App extensions are single-purpose executables bundled with the app.
The OS has many points to be used by app extensions. Next to entitlements giving you special rights, apps can make use of the iOS extensions system. They are stronger protected because misusing them could have fatal consequences. Some entitlements are even restricted to be only used if Apple gives you access to them.
Examples of services that need special entitlements are HealthKit or audio input. These entitlements get signed together with the app and are not changeable. The available APIs don’t allow apps to escalate privileges in order to modify other apps or iOS itself.įor performing specific privileged operations an app needs to declare special entitlements. All system files and resources are protected. Everything outside the app’s home directory is mounted read-only. Apple App Sandbox ( source)Īpple’s App Sandbox is powered by UNIX’s user permissions and makes sure that apps get executed with a less privileged “mobile” user. Therefore, no other app can read or modify data from your app. If an app wants to access data outside of its home directory it needs to use services provided by iOS, like the ones available for accessing iCloud data or the photo album. Apple’s App SandboxĪll apps running on iOS run in a sandbox to make sure the app can only access data which is stored in the app’s unique home directory. It powers iOS security features in a hardware-accelerated way. All iOS devices with an A7 processor or later also have a coprocessor called the Secure Enclave. If you are developing iOS apps lots of security features are already provided by the OS.

We are focussing on three main topics: storing user data safely, secure data transportation, and how to use Apple’s new cryptographic APIs. Therefore, you need to make sure to store this data safely and make data transportation as secure as possible. The basics of iOS App SecurityĬhances are that your app handles private data that you don’t want to end up in the wrong hands.

In another blog post we specifically cover Android App Security. In the last blog post, we have discussed app security more generally for both iOS and Android. You’ll see why it is so hard to get security right and how you can improve your app security by using services from Apple and other providers. Our best practices cover means for securely storing data as well as sending & receiving data over the network. We’ll show you concrete techniques for making your iOS apps more secure. In this article, we focus on iOS App Security.
Protecting this data as well as possible is heavily important and the topic of this article. They deal with a lot of private and sensitive user data like your personal health information or banking information. Smartphone apps are the center of most peoples’ technology usage. Security is important and should never be ignored.
