UPSC is adopting the approach of secure access service edge. Because of the best result of using the secure access service edge architecture. In this post, we will explore more about Secure Access Service Edge UPSC.
Secure Access Service Edge UPSC Introduction
The secure access service edge is a combination of network components. Which is located at the edge of the core network. The main function of this network component is to provide a secure access service for the end-users at the edge of the core network.
The secure access service is based on the following components:
- Secure Access Control Server,
- VPN Connection Server, and
- Secure Access Gateway.
The main purpose of this network component is to allow only specific connections from the edge of the core network. To specific resources in corporate networks which are located beyond the core network. In this context, we will look into two main cases:
Case 1: End-to-End secure connection between user and resource, and
Case 2: Secure connection between user and resource through the intermediate NAT.
How Can Secure Access Service Edge be Helpful in UPSC?
Secure Access Service Edge is the best network component that can provide an end-to-end secure connection. It can be helpful in UPSC because of the following reasons:
End-to-End Security for User to Resource Connection:
In this case, only the secure access service edge knows about the specific user. Which is trying to access the resources in corporate networks which are beyond the core network.
Because of this, we can ensure that only specific users can access the resources in corporate networks. Because of this, we can provide better security for user-to-resource connections.
End-to-End Security for User to Resource Connection through NAT:
In this case, even though NAT is used to provide a secure connection between user and resource. However, only specified users are allowed to access specific resources. Because of this, we can ensure that only specific users are accessing specific resources through NAT.
We can provide better security for user-to-resource connections.
Challenges in Adopting SASE UPSC
There are two challenges in adopting the secure access service edge architecture in UPSC. The main challenges are:
Network Partitioning:
In this case, the network partitioning can be caused by several reasons. These reasons include a disaster or a failure in the network. Because of this, it is impossible to provide complete end-to-end security in UPSC.
We can only ensure that specific users are accessing specific resources. However, we will not be able to ensure that specific users are accessing these resources through secure connections.
Accordingly, we have to use some alternative techniques in UPSC to provide end-to-end security for user to resource connections.
The user and resource communication can be done through alternative techniques. Such as:
- oneway tunneling or through the non-secure channel.
Conclusion
In this article, we have looked into the secure access service edge architecture in UPSC. We have seen that this network component can provide an end-to-end secure connection for the user to resource connection.
However, we have also seen that there are some challenges in adopting this network component. Because of these challenges. We have to use some alternative techniques in UPSC to provide end-to-end security for user to resource connections.
