The PPTP VPN protocol: Is it safe? Security Boulevard.
PPTP: Some quick background. PPTP was created in the 1990s by engineers from Microsoft, Ascend and a group of mobile telecommunications providers such as Nokia. With high-speed internet expanding and e-commerce becoming mainstream, Microsoft wanted to provide Windows users with a basic tool for encrypting their data, and thats pretty much what the team created.

Nowadays, PPTP is considered obsolete for use in VPNs because of its many known security deficiencies. Nevertheless, PPTP is still in use in some networks. The phrase Point to Point refers to the specific type of connection created by the protocol.
encryption How can I tell if a PPTP tunnel is secure? Information Security Stack Exchange.
PPTP has been demonstrated to be broken in many ways, and most installations are insecure. But it is also theoretically not broken if configured correctly. As an end-user, is there a simple way for me to tell if a PPTP tunnel offered to me for example by my place of work, or hosting company is secure? encryption vpn tunneling pptp.

Definition of PPTP PCMag.
Remote users can access their corporate networks via an ISP that supports PPTP. PPTP encapsulates all network protocols for transport over IP. If IP is the source, IP packets ride as encrypted messages inside PPTP packets running over IP. PPTP is based on the point-to-point protocol PPP protocol and the generic routing encapsulation GRE protocol.

L2TP is another blast from the past. It stands for Layer 2 Tunnel Protocol. And if you want some more acronyms thrown at you, I can tell you that this previously popular VPN protocol combined the best parts from PPTP and L2F.
Point Tunneling Protocol an overview ScienceDirect Topics. ScienceDirect.
This frame, with header and trailer, is placed inside another packet and sent over the network between what PPTP calls a PPTP access concentrator PAC and a PPTP network server PNS. PPTP is a client/server protocol with the PAC as the client and the PNS as the server.
PPTP only needs user name, password and server address to establish a reliable connection with the server. Which ports does PPTP run on? PPTP runs on TCP port 1723 and IP port 47 GRE. Which types of encryption does PPTP use?

Protocol Description: PPTP Provides VPN services to remote users. See detailed PPTP description earlier in this document. How the Exploit Works.: By sending a stream of packets using Netcat targeting port 1723, the attacker is able to cause the server to blue screen within a few seconds of initiating the attack. This is caused by the NT PPTP Server having a flaw in it's' code, causing it to be unable to handle certain types of data packets. These malformed packets will cause the system to generate memory leaks in the kernel. This attack sends malformed packets to the listening TCP/IP port 1723. This is not a flaw in the protocol itself, it is actually a flaw in the implementation of the protocol by the vendor Microsoft.
