Network & Endpoint Security

Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and networkaccessible resources. Network
security involves the authorization of access to data in a network, which is controlled by the network administrator.

Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs conducting transactions and communications among businesses, government agencies and individuals.  

Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: It secures the network, as well as protecting and overseeing operations being done.


Access Control

In the realm of network security (we are not concerned with physical access controls in this discussion), access control means limiting access to network resources and data. Access controls are used to prevent unauthorized use of network resources and the unauthorized disclosure or modification of data. This can also include preventing the
use of network resources, such as dial-in modems or limiting Internet access.



Confidentiality is defined as preventing unauthorized disclosure of data. Confidentiality security services prevent disclosure of data in storage, being processed on a local machine, transiting a local network, or flowing over a public Internet. An aspect of confidentiality  is “anonymity,” a service that prevents disclosure of information that could lead to the identification of the end user.
