The Ways to Secure Networks using the Different Principles of Network Administration

The security within the computer networks would primarily comprise of several practices and policies that would be able to prevent the unauthorized access over the system networks, modification, misuse or the denial of a computer network. The security of the networks also involves the access to the vital data within the network that would be mainly controlled by the administrator of the network (Khan et al., 2013).

The security of the networks is a considerable step towards the protection against cyber based attacks. The installation of hardware and software is not enough to secure the networks. It is henceforth advisable to implement proper configuration and high maintenance in order to secure the networks. In many cases, it would be a high matter of concern of the fact of disclosure of information that would be exchanged between the elements of the network and the computer systems (Pathan, 2016).

In order to ensure the smooth working of the data, it is highly necessary to administer the network in order to maintain a control over the network. This would also help in keeping a track of the resources within the network. Hence, it would be highly necessary to follow certain principles for the security of networks.

Five commonly used Principles for Network Security

The principles used for the security of the network are:

Rule Based Management – This is a form of system that mainly consists of ‘if-then’ statements. The rule based system of management could be applied to design the software, which can replace human based experts in order to solve problems.


Firewall Rules – The firewall would help a person to strengthen the level of security within the computer against any form of attacks on the system (Khummanee, Khumseela & Puangpronpitag, 2013).

VLAN Management – An interface of VLAN would be assigned to an IP address, interface description, bridge group. This interface would help in allowing for the communication between the layer two devices with the layer three devices.

Secure Router Configuration – The configuration of the router would be extremely necessary to secure the communication. The firewalls should be enabled in each of the computer within the network that would be in connection with the router and also within the router. The router should be positioned in such a way that so as to maintain the reachability (Biswas, 2017).

Implicit Denial – This form of technology would be highly needed to serve the security of the system. This could also be defined as a secondary form of security or as a secondary phase of the check on the security of the systems. The checkpoint of the security is the primary point for the implementation of the implicit denial. The prime suspects would be kept aside and the correct things are allowed to enter. After the completion of the entire process, the system could be configured on a temporary basis. This would be possible after a proper manual verification is made on the suspects.
