The next-generation (5G) mobile network has a hierarchical structure. For simplicity, just focus on the traditional cellular mode, where a device communicates with a (big) transmission tower.
1. What will you provide as security services in the next-generation cellular network?
2. Briefly describe the mechanisms and protocols that you will choose to achieve that.
Before starting let me explain some thing about cellula technology before 5G.
LTE and GSM, CDMA. These all have cellular topology, with some set of nodes as:
Second one UE latched on Network node (wireless).
And before it connected to Core Network, which call EPC.
EPC have the following nodes:
These all are connected through gigabit/optic fibres.
This EPC connected to conventional PSTN.
Now let’s move for 5G.
As here I explained you about one connection set - UE to nodeB.
but in 5G we will have many set.
As it is going to include IoT, as Internet of things.
Where using the small microcontroller devices, are connected to each other. these devices will have the small paging and minamal data propogations protocol.
Here the security concern very important.
And like the backward technogies it uses the hardware as well software security units.
IoT devices needed to be synced up to their terminal server which must be relevancy for data send. And been triggered on particular time frame paging message.
** You should once search the paging in telecom, similar when you get call, one paging message to broadcasted to entore cellular cell.
Security protocols.: PDCP. which apply the security data convergance on messages.
Have one to one radio security protocols.
on IP data it uses IpSec protocols.
It can extend the range of RNTI to have more secure.
And the protols same as,
MAC, RLC, PDCP and GTP.
Thanks.

Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...
