Network security consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible 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.

Networks can be private, such as within a company, and others which might be open to public access.

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.

The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.

Internet security is a branch of computer security specifically related to the Internet, often involving browser security but also network security on a more general level as it applies to other applications or operating systems on a whole.

Its objective is to establish rules and measures to use against attacks over the Internet.

The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing.

Different methods have been used to protect the transfer of data, including encryption and from-the-ground-up engineering.

Electronic mail, or email, is a method of exchanging digital messages between people using digital devices such as computers and mobile phones.

Email first entered substantial use in the 1960s and by the mid-1970s had taken the form now recognized as email.

Email operates across computer networks, which today is primarily the Internet.

Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging.

Today's email systems are based on a store-and-forward model.

Email servers accept, forward, deliver, and store messages.

Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages.

A web service is a service offered by an electronic device to another electronic device, communicating with each other via the World Wide Web.

In a Web service, Web technology such as HTTP, originally designed for human-to-machine communication, is utilized for machine-to-machine communication, more specifically for transferring machine readable file formats such as XML and JSON.

In practice, the web service typically provides an object-oriented web-based interface to a database server, utilized for example by another web server, or by a mobile application, that provides a user interface to the end user.

Another common application offered to the end user may be a mashup, where a web server consumes several web services at different machines, and compiles the content into one user interface.

Network monitoring is the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator (via email, SMS or other alarms) in case of outages or other trouble.

Network monitoring is part of network management.
