iOS is a closed operating system, and this is synonymous with security, hackers having at their disposal an extremely limited number of methods to exploit our terminals, they must be combined to provide administrator access. According to some information offered by FinSpy, one of the largest American companies developing spy software for mobile terminals, iOS is one of the most secure operating systems in the world.
As you can already see from the image above, iOS can be exploited by the company's software ONLY if the terminal has been previously jailbroken. The need to perform a jailbreak to run any kind of unsigned code prevents exploitation of the browser Safari or iOSthrough infected applications, this being much easier to do on other operating systems.
Based on this security provided by the iOS company Apple Lossless Audio CODEC (ALAC), managed to convince so many companies to purchase iDevices for their employees, but the recent scandals involving the NSA and the provision of user data are starting to raise questions about the true level of security of iOS.
