Definition Of Security And Privacy

Virtual Private Networks (VPNs) are used to allow a remote public connection to an internal network. A VPN is essentially a virtual tunnel connecting a remote user (Tunnel Vision). The traffic within the VPN tunnel is encrypted, and there are two ways to do this. One way is Internet Protocol Security (IPsec) and the other is Secure Sockets Layer (SSL).

OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections and remote access facilities. OpenVPN allows authentication using certificates or username/password. OpenVPN can work in two different modes regarding encryption. It can use static encryption or Public Key Infrastructure (PKI). The advantage of static encryption is that it is very easy to configure. The disadvantage of this type setup is that if your encryption key is compromised, all VPN data can easily be decrypted. The PKI mode resolves many of the issues static encryption has. It

Versa VPN is working as VPN vendor since 2010 to facilitate the users with secure and anonymous browsing.

A VPN is a private network that uses a public network (usually the Internet) to connect

4. Pg 319 VPN. A virtual private network. It’s a type of outsourcing. They use privacy techniques such as tunneling.

VPN refers to the networking technology Virtual Private Network. A VPN allows users connected to this network the ability to access any website or computer data from any location in the world with dedicated and secure networking environment rather than being present in a public server. Majority of VPN users belong to business class industry and educational purposes. VPN networks are used in this manner because majority of VPN networks offer the features like encryption and anonymity which increases the privacy and security benefits while using the VPN network. VPN networks also allow the user ability to perform activities on the internet as if they were accessing

VPN is the abbreviation of Virtual Private Network. A VPN can extend a private network (like local network) across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus benefit from the functionality, security and management policies of the private network [7].

Remote access must be strictly controlled. Remote access allows authorized users to access network resources as if they were at the physical location of the company network. These connections may be made over the phone lines by directly dialing into a remote access server on the network, or they may be made by virtual private networking (VPN).The VPN server will support Layer 2 Tunneling Protocol (L2TP) tunneling with Internet Protocol Security (IPSec) encryption. Dial-in remote access uses modems, servers running the Routing and Remote Access (RRAS) service, and the Point-to-Point (PPP) protocol to enable remote users to access the network.

VPN server: A computer accepts VPN connections from VPNclients. A VPN server can provide a remote access VPN connectionor a gateway-to-gateway VPN connection.

Your network gets secured from hacks when you opt for a VPN service. This is achieved by re-routing all the information to a VPN server where the integrity and the security of the information get verified before being transmitted to your system. This basically involves shielding yourself by controlling the connections with the aid of the best VPN provider. This implies that you should have access to servers that can control your feed.

This type of network is designed to provides a secure, encrypted tunnel in which to transmit the data between the remote user and the company network” (Beal). VPN uses encryption to provide data confidentiality. Virtual Private Networks makes use of encryption and special protocols to provide extra security.

A VPN is a secure protected network called a tunnel for communication purposes over long distances using the Internet as its means of transport. Due to the nature of the communication or transmissions that are being utilized by say a larger corporation, secure and reliable communication is a must. In the beginning these VPN connections were established using one or more dial up modems for users to access the information. Authentication was established by requiring the correct user name and password. As time went on as always things changed, new technology and advances in communication as well as equipment allowed the VPN to evolve and expand. To ensure security, the virtual tunnel is encrypted. VPNs use several protocols in order to encrypt

Remote Authentication Dial-In User Service (RADIUS) offers a centralized access control for remote users. Users are authenticated off of the user list on the RADIUS server. You have the ability to configure the server to hang up and then call the valid user back at a predefined telephone number. Another example of centralized access control for remote users is Challenge Handshake Authentication Protocol (CHAP). CHAP presents a challenge when a user requests access. Access is only granted if the user responds to the challenge correctly. CHAP uses encryption during the process which enhances overall security.

SSL VPN is a newer VPN technology that links an employee’s computer to a corporate network via a web browser. No client software is required, meaning a larger variety of operating systems are potentially supported. The third type of VPN is mobile, in which one of the endpoints of the tunnel is not fixed (Bridwater, 2013).

Businesses are required to have network security considering three primary goals to protect confidentiality, integrity, and availability. Consequently, by using network security mechanisms, firewalls access control prevent unauthorized access to network resources require the appropriate credentials and encrypt global traffic such as any traffic captured off the
