Program Plan Intro

Virtual Private Network (VPN):

  • VPNs are actually virtual networks that are mainly defined for secure communication over public transmission systems.
  • VPN helps to minimize the expense of leasing private point to point connections.
  • Special VPN protocols are used to ensure whether a VPN can carry all types of    data in a private manner. Hence these protocols encapsulate higher level protocols   by a process known as tunneling.

Routing and remote access service (RRAS):

  • RRAS is actually a remote access server software and VPN solution which was developed by Microsoft.
  • RRAS also implements a VPN and also allows a computer to accept different remote client connections on any transmission path.
  • RRAS software controls data encryption and also routes incoming packets to the destination.

Direct Access:

  • Direct access which is also known as unified remote access is a VPN like technology that provides intranet connectivity to client computers when they are connected to the internet.
  • Computers are connected directly when they are connected to the internet in direct access connections.
  • Direct access provides a securely encrypted VPN and also can be deployed for multiple sites.
