REMOTE ACCESS SOLUTION IN WINDOWS SERVER ENVIROMENT
Virtual private network (VPN)
site to site
Definition
A site-to-site communication system This is accomplished through the use of a virtual private network (VPN), which establishes an encrypted link between VPN gateways at each of these locations. A site-to-site VPN tunnel encrypts traffic on one end and sends it over the public Internet to the other, where it is decrypted and routed to its intended destination.
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.
Features
A site-to-site VPN tunnel encrypts traffic at one end and sends it to the other site over the public Internet where it is decrypted and routed on to its destination.
How it works
A site-to-site communication VPN tunnels connect two locations, and only users who are logged into the network may see the data that is being exchanged.
Remote access
Criteria
To use a remote access VPN, users connect to the NAS via the internet. The NAS requires users to provide valid credentials in order to connect to the VPN. The NAS uses either its own authentication process or a separate authentication server on the network to verify these credentials.
Definition
A remote access virtual private network (VPN) encrypts all traffic sent and received by users working remotely, allowing them to safely access and use programmes and data stored in the company data centre and headquarters.
Features
Remote access VPNs are used to create a secure connection between a company's network and the devices that remote workers utilise. Employees can access network resources as if their devices were physically plugged in at the office once they are connected.
How it works
Remote Access from afar VPNs use the public internet to give secure access to a company's network for faraway users. Each device must then validate a user's identity before being allowed to join the network.
Routing Information Protocol (RIP)
Criteria
1) Updates of the network are exchanged periodically.
Updates (routing information) are always broadcast.
Definition
The Routing Information Protocol (RIP) is a dynamic routing protocol that finds the optimum path between the source and destination networks by using hop count as a routing metric.
Features
1) Full routing tables are sent in updates.
2) Routers always trust routing information received from neighbor routers. This is also known as Routing on rumours.
How it works
To determine which path a packet should take to reach its destination, RIP employs a distance vector method. Each RIP router keeps track of its routing table, which is a list of all the destinations it can reach.
Network address translation
Criteria
Network Address Translation (NAT) allows private IP networks with unregistered IP addresses to connect to the internet, conserving IP addresses. NAT converts private internal network addresses into legal, globally unique addresses before forwarding packets between the networks it connects.
Definition
Network Address Translation (NAT) is a process that enables one, unique IP address to represent an entire group of computers
Features
Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network.
How it works
When a packet traverse outside the local (inside) network, then NAT converts that local (private) IP address to a global (public) IP address. When a packet enters the local network, the global (public) IP address is converted to a local (private) IP address.
Network policy server (NPS)
Features
NPS as a RADIUS server for VPN connections and also as a RADIUS proxy to forward some connection requests to members of a remote RADIUS server group for authentication and authorization in another domain.
Definition
NPS as a Remote Authentication Dial-In User Service (RADIUS) proxy to forward connection requests to a server running NPS or other RADIUS servers that you configure in remote RADIUS server groups.
Criteria
manually configure NPS as a RADIUS server, NAP policy server, or RADIUS proxy. Some wizards are provided to assist you with policy and NAP configuration; however, these wizards are opened from the NPS folder tree in the NPS console rather than from the Getting Started section in the details pane of the console.
How it works
-
Network Policy Server (NPS) allows you to create and enforce organization-wide network access policies for client health, connection request authentication, and connection request authorization.
