What is an intranet?

Security can also be increased within the intranet by establishing a database that maintains all of the usernames of people who are allowed access to the network. A secure and reliable intranet requires a web server that is responsible for managing all requests for files hosted on the server, finding the requested file and delivering it to the appropriate computer. A content management system CMS should also be set up to control the creation, publication and management of content on the intranet. An intranet may also consist of many interlinked local area networks LANs as well as leased lines in the wide area network WAN.

Typically, an intranet includes connections through one or more gateway computers to the outside Internet.

Intranet: significance and possible uses

An employee who wants to access the intranet must have a special network password and be connected to the LAN. However, an employee working remotely can gain access to the intranet through a virtual private network VPN. The VPN allows users who are not actually connected to the required LAN to sign into the intranet and access all the same information and functions that would be available had they been connected to the LAN.

Firewall software is essential to the security of an organization's intranet; it stands between the outside Internet and the private intranet.

The firewall will monitor all incoming and outgoing data packets to confirm they do not contain unauthorized or suspicious requests, ensuring malware and other malicious attacks do not leak into the intranet. When a segment of an intranet is made accessible to customers, partners, suppliers, or others outside the company, that segment becomes part of an extranet.

The firewall is especially important for intranet networks that include extranet extensions. The intranet generally looks like a private version of the Internet. The biggest difference between the Internet and intranet is that the Internet can be accessed by anyone from anywhere, whereas the intranet can only be accessed by a specific group of people who possess an authenticated login and are connected to the required LAN or VPN.

Internet Uses

An intranet structure needs key personnel committed to maintaining the intranet and keeping content current.

The networks were operated over telecommunication networks and, as for voice communications, a certain amount of security and secrecy was expected and delivered.

So the enterprise networks are now commonly referred to as enterprise private networks in order to clarify that these are private networks, in contrast to public networks.
