The network segmentation concept used to enhance network security is not very new. Network segmentation is technically the act of separating a computer network and breaking it down severally into subnetworks by which each segment is a network segment. Having such a split has an advantage as it is used as a basis for improving safety and also in performance boosting. In a case where cybercriminals accidentally have access to a network, the segments will aid in providing impactful control limiting any further movement within the network. Operating conventional flat networks is currently an elderly model and a past assumption is that everything within an institution’s network ought to be trusted. Segmentation of a network and also the implementation of appropriate controls mean that anyone can be able to break the network into a multi-layer framework that will in return hinder threatening agents from reaching the hardened technologies thus restricting any type of movement over the network (Cramer, 2013). Officially there is no perfect means of IT network defense infrastructure that can be created thus reducing an attack is the only way that security can be achieved which involves the removal of unwanted access to network sections significantly decreasing the risk of system failure.
Defense-in-depth security practice, when used of a segment, divided the network address into tinier subnets which can be physically divided by routers or VLAN on the switches of the network. Network segmentation buys extra time which can help in detecting an attack. This is because if for example, an attacker manages to break into a network that is segmented it will take time before such an assailant breaks a segment part of the network thus ca be stopped before that happens (Cramer, 2013). Another useful part of segmentation is that it proves total data security meaning it’s easier to protect the most sensitive data as it can be used to create a layer of separation around the servers having confidential information and data.
Segmentation also provides room for the implementation of the lease policy privilege. This means that an organization can restrict access to confidential data from other users protecting it from insider attacks and leakage of crucial and important data. Additionally, network segmentation can help contain harm to the entire system as the affected breached segments can be shut if an attach happens. End-user category groups can also be achieved facilitating access control policy at the egress or ingress points (Cramer, 2013). Network segmentation also is a good way of isolating the network traffic and filtering it to limit and prevent access among the available segments and most importantly is that network segmentation can also run with the existing network equipment meaning an organization saves on cost as they won’t be buying new equipment’s to facilitate network segmentation.
To sum it all network segmentation is a paramount point of network security that any IT organization should run and have because it increases security and also reduces the harm that can happen to a network system in case of cybercriminals’ attacks.

The physical separation of the network requires an extra pc that is connected to the various networks, while in case of logical network separation, internet and intranet connection is managed on just a single computer. This separation helps in security maintenance in computing environment through the prevention of access to the unauthorized user (Luo, & Mesgarani, 2018).
Data storages also operate at a different network which has high security. This allows modification and access privileges to all workers leading high production. The central monitoring and management of the data flow aids in provisions of the better computing environment. A network attached to the storage solution that occurs at different network helps in reduction of the security threads resulting in access of flexibility to modules and users. In computing process, data is volatile in memory and is used only at the time of processing (Wang, Roux, Wang, & Hershey, 2018).
Separation of processing units and non-volatile data ensures the computing resources are efficient and more secure. Because the processing units basically works in a separate network, the possible data modifications always impossible. Networks that are applied to the processing unit and in the data storage are actually separated. For the users to efficiently access the selected computing environment, virtual machines screen must be provided through provisioning the engine (Liu, Shi, Chen, Xu, & Xu, 2018, July). Generally, it is evident that the separation of the network is of great importance in various applications. This is evident by the fact that through the separation of a unit into sub-section seems to work better than when in a general unit. This leads to the conclusion that separation should actually be treated as a technical control system.
