5G Security End to End Architecture

|| 5G Security End to End Architecture ||

Ensuring 5G security across service providers, enterprises, and private networks involves several critical checkpoints, below is end to end architecture with all the possible areas for which security check is required.

Some of the key points to be noted:-

Access control measures must be stringent for devices and network nodes.
Implementing robust authentication protocols and encryption techniques for data transmission.
Secure configuration and management of network devices are crucial
Intrusion detection systems to promptly identify and respond to potential threats.
Constant monitoring, regular security updates, and the enforcement of security policies at various network points/nodes.
Protection against DDoS attacks and secure APIs for inter-device communication.
Compliance with industry standards and regulatory requirements.
