Network Security

What is Network IT Security?

Network security is a form of securing the information of a company from the breach of unauthorized personnel. Furthermore, the organization’s information is kept safe from being changed and misused. Because of this, computer security is guaranteed by using software in addition to encryption tools, thereby allowing secure connections for your computers in addition to the users. A secure user environment is therefore established, ensuring that any actions happening in the organization isn’t compromised.  This kind of security is known as network IT security since it only entails using hardware and software. Network security is usually composed of the following: Auditing, Policy, and Enforcement.


In regards to Network IT security, there’s always a policy. A policy for the IT security is the only documentation of the network security. It plays a big role in ensuring that specific rules are followed in order to assist in the safety of an organization. As of now, many tools and applications are used by employed personnel in order to carry out business as usual. Every company has its own working culture.

That is what drives the working employees to participate in using those tools which are integrated with the sole goal of ensuring security. As usual, certain procedures are followed when administering such tools in an organization. Therefore such procedures should be outlined, in addition to the auditing procedure. This is done with the sole goal of ensuring that the company has adhered to the regulatory compliance. All this information should be included in the coverage.


Network IT security is broadly defined as the way the kind of security is enforced. In terms of enforcement, all that is performed in this section is an analysis of the traffic from the community. Afterward, preservation of ethics, data, and confidentiality in the system is performed. In accordance with these, there are three principles which come about:

• Integrity — During this procedure, assets are altered and handled in a procedural and accepted method.

• Confidentiality –This is the procedure whereby the organization’s information is kept safe from the breach of unauthorized personnel.

• Availability — This is the procedure whereby the users have authorized access to the resources that are accessible.

The stronger the authorities, the more complex the integrity, confidentiality, and availability are attained from the organization’s network. To begin with, traffic stream is categorized by use of content, the users as well as the application. As the primary traffic control, all programs in the system must first pass through the network security firewall whatever the protocol, interface, SSL and evasive tactic to be used by the consumer. Identification of software satisfactorily allows full access to the content being carried through the network stream. Additional management of coverages could be subdivided into a fashion in which applications could be identified and traced back to the consumer. Moreover, the data should always be depicted in order to make certain that Integrity, confidentiality, and accessibility are still put into practice.

The notion of network security is largely observed as the best type of defense, particularly when the network of any organization is procured in the kind of encryption layers. The security layers take under account the following factors: Identification, Access control, Malware detection, Authentication, File type filtering, content filtering, Encryption, and URL filtering.

The layers are put up by an management of firewalls, antivirus software, and Intrusion prevention systems. If it comes down to authorities, the firewall acts as the foundation basis of network security.

With the assistance of modern technologies, traffic across all ports is observed. Moreover, applications, in addition to their content, can be categorized and thus the users may also be traced. Because of this, control and accessibility can be termed as a way to make certain that the coverage of IT security is applied equally as to every employee of the organization with no compromise.

Additionally, network security is layered in order to make sure that the organization’s resources are safeguarded adequately. Antivirus and Intrusion prevention systems are among the resources that assist in assessing the content from the network traffic and prevent malicious attacks by those who have access to the system. However, the complexity of the network IT security, in addition to add elements, may add up some additional costs. Because of this, you must take into account whether the add-on elements have key advantages as pertaining to the safety of the network and if they will help in the strengthening of their firewall.


This is a procedure whereby measures pertaining to authorities are reviewed once again to assess how well they’ve stuck to the community IT security policy. Auditing can help to breed an environment whereby an organization is tasked with ensuring that the policies have adhered to the letter. Because of this, the organization has the capability to change their enforcement tactics in addition to the policy whenever there’s the requirement of an evolved form of community IT security.
