Vratislav Holub Apple devices are generally considered to be more secure. Especially when we focus on, for example, Macs or iPhones, or their competition in the form of Windows and Android systems. Apple products do not often encounter malware, for example, and already offer a variety of functions to prevent unauthorized entities from tracking. A processor called Secure Enclave also has a relatively large share in the overall security of these pieces. If you're an Apple fan, you've definitely heard of it. What is it actually for, where is it located and what is it responsible for?

Adam Kos The Secure Enclave operates as a separate processor that is completely separate from the rest of the system and has its own core and memory. As it is isolated from the rest, it brings significantly greater security and is therefore used for storing the most important data. But don't be fooled - Secure Enclave is not used to store your data directly and therefore does not work like an SSD disk, for example. In this, this processor is limited by a small flash-type memory, due to which it would practically not be able to store even a few reasonably high-quality photos. It only offers 4 MB of memory.
Securing the most sensitive data
In connection with this chip, the most common talk is its use in combination with Face ID and Touch ID technologies. But before we get to that, it is necessary to explain in detail how these biometric authentication methods work. The data (in the form of mathematical notation), which is used for comparison during each subsequent authentication, is of course thoroughly encrypted and cannot be decrypted without a so-called key. And it is this unique key that is stored within the Secure Enclave processor, due to which it is completely separated from the rest of the device and cannot be accessed, only in these cases.
The Secure Enclave is part of the M1 chip
Although the data itself is stored outside the Secure Enclave, which serves only to store the key, it is still thoroughly encrypted and only this processor can access it. Of course, they are also not shared or stored on the Apple user's iCloud or Apple's servers. No one from the outside has access to them, so to speak.

The Secure Enclave processor is now considered an integral part of Apple products. In this regard, Apple again benefits from the excellent interdependence between hardware and software. Since he literally has everything under his thumb, he is able to adapt his products to it and offer benefits that we simply do not meet with other manufacturers. Secure Enclave thus protects Apple devices from attack by outsiders and possible theft of sensitive data. It is thanks to this part that it is practically impossible to unlock Touch ID and Face ID security remotely, which of course is not only used to unlock the phone, but can also lock data, applications and more.
The usual excess of the word "giant" was replaced this time by the word "not at all" 😅
And again a bunch of grammar mistakes (not at all unusual for this server)
