What is VPN in Microsoft?
Point-to-Point Tunneling Protocol (PPTP), now commonly referred to as VPN (Virtual Private Networking) is Microsoft's version of PPP that encapsulates packets from other protocols for transmission over an IP network. It is used to create a secure network utilizing public lines (the Internet). VPN essentially enables users access to a secure corporate network from remote locations (such as from a salesperson's portable computer located in a hotel room). Prior to VPN, a dedicated rented line was required from point-to-point to assure high levels of security.
What are the two methods of remote access?
First, you need to consider two distinct methods of remote access, each of which uses different protocols: Dial-up. Virtual private networking (VPN) Within each method, there are three basic categories for protocols: Connectivity. Authentication.

What protocol is used for dial up encryption?
For data encryption in a dial-up session in a Windows network. In order to use MPPE, the authentication protocol for the dial-up session must be either EAP-TLS or MS-CHAP version 1 or 2. VPN protocols.
What is virtual private network?
Virtual private networking protocols encapsulate PPP frames (the data units at the data link layer of the OSI model) into IP datagrams at the network layer. These datagrams are then sent across an internetwork, which can be either a private network or, more commonly, the Internet. This encapsulation creates a “tunnel” that acts like a dedicated WAN link, even though it usually uses the Internet—thus, a “virtual” private network.
Why do you want to be encrypted in a remote session?
First, you want the best security you can provide for the remote session. You want authentication to be encrypted so that someone who is snooping cannot see it , and you want the data that is passed in the remote session to be encrypted for the same reason. Second, older systems and their associated protocols are less capable in terms ...
What is dial up modem?
Dial-up involves one modem connecting with another over the Public Switched Telephone Network (PSTN), creating a temporary, dedicated WAN link. There are three possible protocols for making the initial connection: Point-to-Point Protocol (PPP), Serial Line Internet Protocol (SLIP), and Asynchronous NetBEUI (AsyBEUI). Table A explains their differences.
Why is SLIP needed in NT?
Serial Line Internet Protocol (SLIP) SLIP is used as a client in NT or Win2K only when necessary to connect to an older server that is not supporting PPP.
Why is access control important?

Remote access connection allows users to access a network or computer remotely via an internet connection or telecommunications. This post is dedicated to secure remote access.
What is remote desktop connection?
Remote Desktop Connection (RDC) is a Microsoft technology that allows a local computer to connect to and control a remote PC over a network or the Internet. The host computer can see and interact with the target computer through the target computer’s actual desktop interface—allowing the host user to see exactly what the target user sees. It is done through a Remote Desktop Service (RDS) or a terminal service. Microsoft Windows, Linux, and MacOS have the software available that allows for remote desktop access.
What is remote assistant?
The remote assistant can be considered a subset of the remote desktop. When you connect to another computer using the remote desktop, the current user of that computer is forced to sign-out. In other words, if an employee asks you for help with a problem and you use a remote desktop to connect to his computer, it is not possible for both of you to be able to view the desktop at the same time and do the necessary work. In terms of technical support, this is a huge problem. To solve this problem, remote assistant technology was introduced. In remote assistant, technical support person and an employee with a problem are able to connect to a computer at the same time.
What are the types of remote access?
Traditionally, enterprises used modems and dial-up technologies to allow employees to connect to office networks via telephone networks connected to remote access servers. Devices connected to dial-up networks use analog modems to call assigned telephone numbers to make connections and send or receive messages.
How does remote access work?

How many protocols are there in the network?
To get started, this glossary explores 12 common network protocols all network engineers should be familiar with. This includes the protocols' main functions, as well as why these common network protocols are important.
Why is ARP not required?
ARP isn't required every time devices attempt to communicate because the LAN's host stores the translated addresses in its ARP cache, so this process is mainly used when new devices join the network.
What is BGP in LAN?
Border Gateway Protocol. BGP makes the internet work. This routing protocol controls how packets pass through routers in an autonomous system (AS) -- one or multiple networks run by a single organization or provider -- and connect to different networks. BGP can connect endpoints on a LAN to one another, and it can connect endpoints in different LANs to one another over the internet.
What is a DHCP handshake?
When a device connects to a network, a DHCP handshake takes place, where the device and DHCP server communicate. The device establishes a connection; the server receives it and provides available IP addresses; the device requests an IP address; and the server confirms it to complete the process.
What is the purpose of TCP and IP?
Common network protocols, including Transmission Control Protocol (TCP) and Internet Protocol (IP), enable the exchange of information across the internet and work behind the scenes so effectively that many users don't think twice about them or how the internet works. For networking professionals, network protocols are critical to know and understand. But that doesn't make understanding these protocols easy.
What is external BGP?
External BGP directs network traffic from various ASes to the internet and vice versa. Additionally, internal BGP directs network traffic between endpoints within a single AS.
How does IP work?
IP functions similarly to a postal service. When users send and receive data from their device, the data gets spliced into packets, which are like letters with two IP addresses: one for the sender and one for the recipient. After the packet leaves the sender, it goes to a gateway, like a post office, that directs it in the proper direction. Packets continue to travel through gateways until they reach their destinations.
