as two of the most popular systems for developers, Android and Apple iOS have been a subject of concern, and the contrast between the two systems, especially the security of secure iOS apps, has been debated for years. The openness of Android makes it universal and risky, and the closeness of Apple iOS makes developers more constrained but also secure, so it has always been a common belief that iOS apps are more secure.
First, look at the security of iOS apps from two big systems
Android System:Android is open, the application can read the global public directory of the SD, in other words, the application can read data between each other, as long as they know the location and format of their data can be read or modified. As a result, applications can generate a lot of data intersections between each other, and there are many things that can be delegated to each other, which explains why some users are having traffic, spending spikes, or installing a hidden charge with a virus app. iOS app security
iOS System:iOS system is a closed system, in the development of iOS application security, developers need to follow Apple to set the developer agreement, not follow the agreed protocol and development of the app will not be audited through the App Store, so that developers in the development of the application must comply with a certain protocol, There is no permission to manipulate any content that is not in this program directory. iOS app security
iOS app security risks from the above, the iOS app is secure relative to the Android system, but is it really safe for iOS apps? As is known to all, the Apple App Store is heavily audited, but there are thousands of app reviews submitted every day, and malware is getting better, or getting some malware into the APP store from the seams of auditing. As far as Apple is concerned, the difficulties it faces are also very bad. iOS app security. According to the latest survey of a foreign security service provider, 87% of the top 100 paid apps in iOS were hacked. In addition to free iOS app security is cracked, more and more billing applications are cracked, cracked application types include various types, including games, business, production, finance, social, entertainment, education, medical and so on. These fee-charging applications originally need to be paid for download, and after being cracked, users do not have to pay to download. Intra-purchase cracking, source code cracking, local data theft, local data theft, cyber security risks, and iOS application security risks everywhere.
Security risks for iOS apps 1, internal purchase hackPlugin Method (jailbreak only), Itools tool replacement file Method (common for archive hack), eight-door artifact modification2. Network Security RiskIntercept network requests, crack communication protocols and impersonate client logins, falsify user behavior, and harm user data3. Application function patch hackPatch hack your app with flex patch software by dispatching return values4. Source code Security Riskreverse-Assemble the IPA code using disassembly tools such as IDA, resulting in core code logic and modifications that affect iOS app securityIn the face of so many risks, how to protect the security of iOS apps? It is understood that the mobile application security platform-love encryption, the introduction of the iOS application of secure encryption technology, the following see, iOS Application Security encryption technology
Secure encryption technology for iOS apps 1. Local Data encryptionEncrypt nsuserdefaults,sqlite storage file data, protect account and key information2. URL encoding Encryptionencrypt URLs that appear in the program to prevent URLs from being statically parsed3, Network transmission data encryptionprovides encryption scheme for transmitting data to client, effectively prevents interception of data through network interface4, method body, method name high-level confusionconfuse the method name and method body of the iOS app security program to ensure that the code is not parsed after the source is reversed5, the program structure of mixed-line encryptionconfusing the application's logical structure to ensure that the source readability is minimized
