Remote and Dial-up Connections

4. is a form of Internet access that uses the facilities of the public
switched telephone network (PSTN) to establish a dialed connection
to an Internet service provider (ISP) via telephone lines. The user's
computer or router uses an attached modem to encode and decode
Internet Protocol packets and control information into and from
analogue audio frequency signals, respectively.

12. Broadband Internet Access
Broadband Internet service truly is the most used form of Internet access
because of its high access speeds; it is offered in four different forms, DSL
(or Digital Subscriber Line), also fiber-optic, cable, and satellite.
The old dial-up connection is the only non-broadband internet service available,
and even though it is cheaper, most Internet users are moving towards the
faster broadband Internet connection.

22. VPN is special type for WAN(Wide Area Network) which achieves to connect
without use leased private lines. It uses to establish Internet.
Development of VPN is to establish secure and cost effective long distance links
between two or more computing networks.
VPN has its own set of software programs, protocols and security constructs
which make secure connectivity possible.
The USP of virtual private computer networks over conventional computer
networks lies in the fact that this technology is a significantly low cost alternative.

2. Peer to peer VPN (can let two separate local area networks, to be linked
together)
3. Private VPN (private intranet of a company that allows enabling of access
control for each user)

Types of VPN

25. How VPN Works
Install VPN client programs on the machines which need remote access
Enable Internet connectivity provided by an ISP, after verification of user name
and password.
Access the private network easily use client remote computer.

26. Benefit of VPN
Substantially easy and inexpensive to set it up
Can provide long distance connectivity, between multiple branches of a company
office, by providing secure data transfer and encryption, to enable video
conferencing, as well as data transfer.
Reduces the costs involved in maintaining long distance networks and costs of
operation.
VPN is a technology that are really cost effectiveness, efficiency and security
features of virtual private networks make them attractive and preferred choices
over conventional leased line based networks. Because of that, most industry
Intranets use VPN technology to establish internal connectivity.

41. Authentication Protocols
PPP uses two authentication protocols PAP and CHAP.
CHAP is the preferred protocol, because CHAP uses 3-way handshake;
whereas, PAP uses 2-way handshake.
CHAP is an authentication scheme used by Point to Point Protocol (PPP)
servers to validate the identity of remote clients.
CHAP provides better security as compared to Password Authentication
Protocol (PAP). The protocol exists in two versions,
MS-CHAPv1 and MS-CHAPv2

42. Authentication Protocols
PAP : Sends username and password In clear text
SPAP : shiva LAN Rover client encrypts password but not data
Challenge-Handshake Authentication Protocol (CHAP):
encrypt username and password but not data , for non-Microsoft
operating systems
Ms-CHAP1 : one way password encryption
Ms-CHAP2 :mutual authentication , stronger encryption .(NT+98,VPN only)
