It is necessary to ensure the following security properties of Internet of Things devices:

1) a reliable access and authentication system based on cryptography. Encryption is necessary to protect communication between iOS devices, and cryptographic device identifiers are needed for this. You need to make sure that only authorized users have access to connected devices;

2) cryptographic security of the software. Using the PKI system to sign the code and verify its authenticity;

3) software updates throughout the entire lifecycle of devices.

From the point of view of ensuring the security of Yota networks should be provided:

1) cryptographic data protection;

2) the absence of critical dependencies on connectivity. Maintaining critical functionality by the system even in the absence of communication;

3) creating an additional device specification that describes in detail the required security policy for a specific device. [31]

The security of the cloud platform is ensured by:

1) control of access to device resources. The application declares a set of resources that it would like to access, while the platform provides a list of devices with these resources. Accordingly, the user gets the opportunity to choose which devices and their capabilities this application can have access to, thereby authorizing the application.;

2) two-factor user authentication technology to increase the level of security;

3) verification of applications for the presence of malicious code. [31]
