REMOTE ACCESS SOLUTION IN WINDOWS SERVER ENVIRONMENT
VIRTUAL PRIVATE NETWORK (VPN)
1) SITE-TO-SITE
Keeps data encrypted between two locations without needing credentials or client apps on devices using it.
DEFINITION
It works by creating a “tunnel” between two networks.
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.
HOW IT WORKS
Site-to-site VPNs are intended to connect entire networks, usually from different locations. They work by routing traffic between two site-to-site VPN tunnels.
FEATURES
2) REMOTE ACCESS
Enables users who are working remotely to securely access and use applications and data that reside in the corporate data center and headquarters, encrypting all traffic the users send and receive.
DEFINITION
Creating a virtual tunnel between an employee's device and the company's network.
HOW IT WORKS
Should be available from any device or browser.
It should provide monitoring and reporting
FEATURES
ROUTING INFORMATION PROTOCOL(RIP)
A distance-vector routing protocol.Routers running the distance-vector protocol send all or a portion of their routing tables in routing-update messages to their neighbours.
DEFINITION
RIP uses a distances vector algorithm to decide which path to put a packet on to get to its destination.
Each rip router maintains routing-table which is a list all the destinations the router knows how to reach.
Each router broadcasts its entire routing tsble to its closest neighbors every 30 seconds.
HOW IT WORK
RIP uses a modified hop count as a way to determine network distance.
FEATURES
NETWORK ADDRESS TRANSLATION
conserves IP addresses by enabling private IP networks using unregistered IP addresses to go online.Before NAT forwards packets between the networks it connects,it translates the private internal network addresses into legal,globally unique addresses.
DEFINITION
When 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.
HOW IT WORKS
A single network card connected to a single internal ,private network and may have multiple networks cards connected to public networks.
FEATURES
NETWORK POLICY SERVER(NPS)
Allowss to create and enforce organization-wide network access policies for client health,connection request authentcation and connection request authorization.
DEFINITION
Authorized to connect to the network and the circumstances under which they can or cannot connect.
During the authorization process, NPS determines whether the user or computer is allowed to access the network.
HOW IT WORKS
As a RADIUS server,NPS perform centralized connection authentication,authorization an accounting for many types of network access,including wireless ,authenticating switch,dial-up and VPN remote access,and router-to- router connection.
