Vpn Uses Data Integrity And Privacy - 1906 Words

A VPN can connect multiple sites over a large distance just like a Wide Area Network (WAN). VPNs are often used to extend intranets worldwide to disseminate information and news to a wide user base. Educational institutions use VPNs to connect campuses that can be distributed across the country or around the world. There are a number of VPN protocols in use that secure the transport of data traffic over a public network infrastructure. Each protocol varies slightly in the way that data is kept secure. VPN technology employs sophisticated encryption to ensure security and prevent any unintentional interception of data between private sites. All traffic over a VPN is encrypted using algorithms to secure data integrity and privacy. VPN architecture is governed by a strict set of rules and standards to ensure a private communication channel between sites. A VPN uses data encryption and other security mechanisms to prevent unauthorized users from accessing data, and to ensure that data cannot be modified without detection as it flows through the Internet. It then uses the tunneling process to transport the encrypted data across the Internet. Tunneling is a mechanism for encapsulating one protocol in another protocol. In the context of the Internet, tunneling allows such protocols as IP to be encrypted and then encapsulated in IP. Similarly, in the context of VPNs, tunneling disguises the original network layer protocol by encrypting the packet and enclosing the encrypted packetShow MoreRelatedCase Analysis : Topaz Information Solutions1184 Words   |  5 Pages(HIPAA).

This calls for the use of a few protocols that makes this a success. To achieve it, one can either make use of the AH or even ESP. research shows that the two can be used together or even separately. This essay will focus on the functionality of AH and ESP, their main activities and their advantages over each other.

SSL and TLS SSL and TLS protocols use TCP port 443 and it is a transport layer protocol. SSL and TLS uses various types of cryptographic features that provides digital signatures, integrity and confidentiality. While communicating between client and server unlike IPsec, SSL/TLS provides cipher suites to outline the set of cryptographic tasks. By using a SSL server certificate the SSL VPN gateway can be authenticated to the Web user for verification purposes whetherRead More VPN or Virtual Private Network Essay1164 Words   |  5 Pages VPN Introduction:   Ã‚  Ã‚  Ã‚  Ã‚  VPN stands for Virtual Private Network. VPN is a data network connection that makes use of the public telecommunication infrastructure but maintains privacy through the use of a tunneling protocol and security procedures. It operates much like a Wide Area Network (WAN).   Ã‚  Ã‚  Ã‚  Ã‚   Most companies actually leased lines, but in either case both solutions are very expensive.

A virtual private network (VPN) is an addition of a private network that bridges the connection between a shared or public network. It allows you to send data between two computers in a point to point private link (Microsoft, Virtual Private Networking: An Overview). VPN allows individuals and companies to connect two locations securely and remotely. For example, if one company branch is in Secaucus, NJ and the other is in Newark, NJ; they can securely accessRead MoreA Virtual Private Network ( Vpn )1213 Words   |  5 PagesIntroduction A virtual private network (VPN) is a private network that extends across a public network, same as the Internet. It allow user to send and receive data across networks that can be either shared or public as if it’s their own device were connected on private network. Application running across VPN have functionality, security, management of the Private network. VPN allow employees to securely access a corporate intranet while located outside the office site. They are used for geographicallyRead MoreAircraft Solutions Assessment Essay1096 Words   |  5 Pagesthat encrypt the transferred data must be implemented. The internal IT team should consider installing IPSec tunnels, which enable a connection between two hosts or end points to be secured by IP payload and encapsulated encryption. Enabling these protocols provides a secure connection, essentially limiting the potential hijack of service or confidential data. Hackers often place themselves in between the two servers or a VPN to intercept the data and in turn use that data, which could have user informationRead MoreVpn1217 Words   |  5 PagesVPN Introduction: VPN stands for Virtual Private Network.
