Wilson Veteran of the Digi Community 1, points. Ok, where to begin After having getting what you are trying to do working it took 3 weeks I know understand why Cisco does not feel the least bit threatened by Microsoft.
First: You cannot use VPN dial in to make this work. It doesn't work, none ot the tick boxes and presse buttons work like use static IP, etc The connection is private because the contents of the datastream moving inside the VPN connection are encrypted so that no one over the Internet is able to intercept and read the contents of the communications moving over the VPN link. These are:. The reason why PPTP is the least secure option is that user credentials are not exchanged over a secure link.
That is to say, encryption of the VPN connection takes place after credentials are exchanged. Even though actual credential information is not transmitted between VPN client and server, the hash values exchanged can be leveraged by sophisticated hackers to gain access to VPN servers and connect to corporate networks. Hackers are not able to access the user credentials and thus cannot steal them to use them later. IPSec provides for mutual machine authentication, data integrity, confidentiality, and non-repudiation.
L2TP supports PPP and EAP user authentication mechanisms, which allows for a high level of log on security because both user and machine authentication is required. I should note here that VPN connections are more about privacy than security. While I do recognize that privacy is a major component of secure communications, privacy in and of itself does not provide security.
VPN technologies provide for privacy of communications over the Internet, which prevents intruders from reading the contents of your communications. VPN technologies also allow you to make sure that only authorized users can connect to the network through the VPN gateway.
However, privacy, authentication and authorization do not provide a comprehensive security solution. For example, suppose you have an employee who you have granted VPN access. Everyone is happy until one day one of your users connects to your SQL server to access payroll information and starts to share that information with other employees.
What happened? Wasn't the VPN connection secure? Yes, the VPN connection was secure to the extent that it provided privacy, authentication and authorization - but one thing it did not provide was access control, and access control is the most pivotal aspects of computer security. In fact, it can be argued that without access control, all other security measure are of relatively little value.
