It’s necessary for desktop sharing and remote access for help desk activities. The primary remote access protocols in use today are the Serial Line Internet Protocol (SLIP), Point-to-Point Protocol (PPP), ...

What is PPP protocol?

PPP is a remote access protocol that allows you to implement TCP/IP. It establishes a connection via point-to-point links (i.e., dedicated leased lines and dial-up). PPP is used most often for remote connections to LANs and ISPs. PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host ...

How to use PPTP?

To use PPTP, you’ll have to set up a PPP session between the server and the client, usually over the internet. Once the session is established, you’ll create a second dial-up session. This dial-up session will use PPTP to dial through the existing PPP session.

What is PPTP in a network?

PPTP is a remote access protocol, based on PPP, created by Microsoft. It’s used to establish virtual connections across the internet via PPP and TCP/IP, enabling two networks to use the internet as their WAN link while retaining the security benefits of a private network.

What is remote access server?

Remote access servers can be configured as dial-in servers or VPN servers. Dial-in servers use the Point-to-Point Protocol (PPP) or in the case of some older servers, the Serial Line Internet Protocol (SLIP) as the link layer protocol. VPN servers can use the Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), or IPSec tunnel mode to establish a secure "tunnel" over the Internet. Windows remote access servers support the following set of authentication methods: 1 Password Authentication Protocol (PAP) 2 Challenge Handshake Authentication Protocol (CHAP) 3 Microsoft's implementation of CHAP (MS-CHAP) 4 Updated version of MS-CHAP (MS-CHAP2) 5 Extensible Authentication Protocol/Transport Layer Security (EAP/TLS)

The authenticator also calculates the hash value and compares the client's response with its own calculation. If the values match, the connection is established.

Why is PAP not supported?

For security purposes, PAP can be excluded as a viable option for most businesses because it sends passwords across the phone line or Internet in plain text. The only reason to use PAP is if the remote access client and remote access server are not able to negotiate a more secure authentication method. Many VPN/firewall products do not support PAP because of the security issue.

EAP/TLS provides for use of more secure authentication methods such as smart cards, Kerberos, and digital certificates, which are much more secure than the user name/password authentication methods above. It's defined in RFC 2716.

What is the protocol used for dial in VPN?

Dial-in servers use the Point-to-Point Protocol (PPP) or in the case of some older servers, the Serial Line Internet Protocol (SLIP) as the link layer protocol. VPN servers can use the Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), or IPSec tunnel mode to establish a secure "tunnel" over the Internet. ...

What is the most secure remote authentication protocol?

Extensible Authentication Protocol-Transport Level Security is the most secure remote authentication protocol. It uses certificates on both the client and the server to provide mutual authentication, data integrity, and data confidentiality. It negotiates encryption algorithms and secures the exchange of session keys. Use EAP-TLS if you implement multifactor authentication technologies, such as smart cards or universal serial bus (USB) token devices.

What port does XTACACS use?

This protocol is also an application layer protocol and observes the client/server model. Since TACACS+ is also a well known protocol, it stands to reason that there is also a well known port associated with this activity, which is TCP Port 49. That being said, XTACACS uses UDP. There is always the exception to the rule!

What is a tacs?

Terminal Access Controller Access Control System , or TACACS, is similar to RADIUS and is used to regulate access to the network. One of the biggest differences between TACACS and RADIUS is that TACACS primarily uses TCP for its transport protocol needs vs. the UDP that RADIUS will use. There are also three versions of TACACS with TACACS+ being the most recent. It is important to note that TACACS+ is not backwards compatible with the other earlier versions. This protocol is also an application layer protocol and observes the client/server model. Since TACACS+ is also a well known protocol, it stands to reason that there is also a well known port associated with this activity, which is TCP Port 49. That being said, XTACACS uses UDP. There is always the exception to the rule!

Can you use PPP on a Radius router?

Notably, you can use PPP, PAP, and CHAP to name most of them. If you are familiar with Cisco Systems gear or are in charge of supporting the routers and switches from them, then you are no doubt familiar with the various authentication methods offered by RADIUS.

Does RADIUS use UDP?

Based on the above access controls, the user is either authenticated or rejected. RADIUS itself, as mentioned earlier, uses UDP as its transport protocol, which was decided during the initial design considerations for RADIUS. Using UDP has its advantages, notably there being less overhead and speed.
