What is "open PPPoE" and what security risks does it pose?

Similar questions: open PPPoE security risks pose.

What is Open PPPoE Open PPPoE is basically the same PPPoE. The difference is that usernames/passwords are not enforced. Any username/password combination can be used to connect to the ISP and hence the Internet.It's an authentication step the ISP is eliminating.

For instance, in todays DSL modems you need to enter your username & password in the modem & authenticate with the ISP before you are allowed Internet access. Regardless of entering the username & password the DSL modem will still sync. They are eliminating the need to enter a valid username & password in order to obtain Internet access.

I don't think it poses any added security risk to the end user. Take a look at cable modems. Cable modems don't require usernames & passwords to be entered in their configuration.

They just need to be provisioned in the cable companies system. Sources: Experience .

Point-to-Point Protocol over Ethernet PPPoE is a tunneling protocol which allows layering IP, or other protocols that run over PPP, over a connection between two Ethernet ports, but with the software features of a PPP link, so it is used to virtually "dial" to another Ethernet machine and make a point to point connection with it, which is then used to transport IP packets, based on the features of PPP. It allows the use of traditional PPP-based software to handle a connection which does not use a serial line, but a packet-oriented network like Ethernet, to provide a classical connection with login and password for Internet connection accounting. Also, the IP address on the other side of the link is only assigned when the PPPoE connection is open, allowing the dynamic reuse of IP addresses.

PPPoE was developed by UUNET, Redback Networks, and RouterWare. The protocol is specified in RFC 2516. Note that some vendors (Cisco and Juniper, for example) refer to PPPoEoE (PPPoE over Ethernet), which is PPPoE running directly over Ethernet or other IEEE 802 networks or over Ethernet bridged over ATM, in order to distinguish it from PPPoEoA (PPPoE over ATM), which is PPPoE running over an ATM virtual circuit using RFC 2684 and SNAP encapsulation of PPPoE.(PPPoEoA is not the same as Point-to-Point Protocol over ATM (PPPoA), which doesn't use SNAP.

Point-to-Point Protocol over Ethernet PPPoE, Point-to-Point Protocol over Ethernet, is a network protocol for encapsulating PPP frames in Ethernet frames. It is used mainly with ADSL services. It offers standard PPP features such as authentication, encryption, and compression.

Unfortunately it has an MTU lower than that of standard Ethernet which can sometimes cause problems with badly configured firewalls.

1 I'm asking what "open" PPPoE is, not plain PPPoE. Thanks .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
