Remote Access Solution in Windows Server Environment
Virtual Private Network (VPN)
a. Site to Site
CRITERIA:In order to set up an internet-based site-to-site VPN between two sites, a VPN gateway (router, firewall, VPN concentrator, or security appliance) such as the Cisco Adaptive Security Appliance (ASA) is required at both sites.
DEFINITION:A connection between two or more networks, such as a corporate network and a branch office network.
FEATURES:Creating an encrypted link between VPN gateways located at each of these sites.
HOW IT WORK:It works by creating a “tunnel” between two networks. With a site-to-site VPN, these tunnels go from one location to another, and the only people who can see the data being transferred are users logged onto the network.
b. Remote access
DEFINITION:enables users who are working remotely to securely access and use applications and data
CRITERIA:Users connect to the NAS over the internet in order to use a remote access VPN. In order to sign in to the VPN, the NAS requires that users provide valid credentials.
FEATURES:
Remote access should be available from any device or browser
No client-side installation or maintenance should be required
HOW IT WORK:A remote access VPN works by creating a virtual tunnel between an employee's device and the company's network.
Routing Information Protocol (RIP)
CRITERIA:RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination.
DEFINITION:One of the oldest distance-vector routing protocols which employs the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination.
FEATURES:
Updates of the network are exchanged periodically.
Updates (routing information) are always broadcast.
HOW IT WORK:RIP uses a distance vector algorithm to decide which path to put a packet on to get to its destination
Network Policy Server (NPS)
CRITERIA AND FEATURES:Allows you to create and enforce organization-wide network access policies for connection request authentication and authorization.
DEFINITION: The Microsoft implementation of a Remote Authentication Dial-in User Service (RADIUS) server and proxy.
HOW IT WORK:Network policies are sets of conditions, constraints, and settings that allow you to designate who is authorized to connect to the network and the circumstances under which they can or cannot connect.
Network Address Translation
CRITERIA AND FEATURES:A method of remapping one IP address space into another by modifying network address information in (IP) Internet Protocol datagram packet headers while they are in transit across a traffic routing device.
DEFINITION:It's a way to map multiple local private addresses to a public one before transferring the information.
HOW IT WORK:When a packet traverse outside the local (inside) network, then NAT converts that local (private) IP address to a global (public) IP address.
