Currently, more and more businesses are making use of network segmentation and adding it to their systems to bolster their security.
This means that any application running through a VPN will be able to use the functions, security and management features of the private network that the VPN is connected.
When a business makes use of VPN technology, it can help to ensure that remote workers and other offices can establish a secure connection to the head office’s network without the risk of an attacker infiltrating the network through the remote user.
Proper use of network segmentation to improve levels of security would involve splitting segmenting your network into those different subnetworks and given each subnetwork a certain level of required authorization for access.
Role-based access controls (RBAC) help to restrict access to certain systems, based on the level of authorization that a user has.
Firstly, they decided that their security architecture would need to confirm the ID of the user, what device they are using and the permissions they have to access certain directories.
The original SDP products for commercial use was implemented using an overlay network for business applications, examples of these are remote access to high-value data, or to protect the cloud system from attacks.
The SDP Client has a real-time configuration to make sure that the mutual TLS VPN connection is only linked to items that the individual user is authorized to use.
This means that the SDP Client serves the function of placing restrictions on access to certain data points based on the user’s level of authority.
The SDP Controller serves the function of a trusted middleman between the backend security features such as the Identity Provider and the Certificate Authority to the SDP Client itself
