Don't use Microsoft PPTP. Again, this attack is against Microsoft PPTP, not PPTP in general. PPTP allows all sorts of encryption and authentication schemes; Microsoft just invented some really lousy ones. Even better, if you are a VPN user, use IPSec. This is a much more robust protocol. 7. Are there alternatives? The main alternative is IPSec.

In fact, it is the fastest of all VPN protocols. That means it’s a great option for applications where speed is important such as streaming and gaming. That being said, PPTP is not as secure because of its weak encryption You should avoid this type of VPN service. Here are the reasons why VPN services with only PPTP protocol are not secure: 1. It Is An Obsolete Security Protocol. PPTP has been used since the era of Windows 95, and the security protocol has not been updated as often as the other more advanced security protocols with strong encryption today. Secure your MS-CHAP v2/PPTP based tunnel with PEAP. For information on how to secure your MS-CHAP v2/PPTP based tunnel with PEAP, see Microsoft Knowledge Base Article 2744850.

Oct 20, 2016 · In short, don’t use PPTP if you care at all about security when setting up a VPN. Instead, opt for a more secure protocol: OpenVPN, L2TP/IPSec, SSTP, or IKEv2. Alternatives to PPTP. Other VPN protocols are either not as easy to set up as PPTP or do not come pre-installed on popular operating systems. However, IPSec is a whole lot more secure. PPTP is a lot more stable than IPsec. However, PPTP is a lot easier to block with the firewall. IPSec has the ability to encrypt traffic in a way that the end application is not aware of the encryption. So PPTP is faster than IPSec and a lot easier for the VPN provider to configure. PPTP Versus OpenVPN Apr 04, 2018 · Point-to-point tunneling protocol is a common protocol because it’s been implemented in Windows in various forms since Windows 95. PPTP has many known security issues, and it’s likely the NSA (and probably other intelligence agencies) are decrypting these supposedly “secure” connections. Sep 11, 2019 · It’s not quite as secure as OpenVPN, but much safer than PPTP and it’s pretty quick as well. Finally, companies that rely on remote working and mobile devices may want to check out IKEv2 . It’s not the most common protocol, but IKEv2 is extremely flexible, automatically reconnecting if encryption is interrupted.
Sep 26, 2012 · In order to not make it too easy for the cracker, we established a test connection to a PPTP server with a very good password. Produced by a generator, the 16-character Nao;hi2chie)toh1 was complicated enough to satisfy even strict password requirements. Then, we recorded an iPhone's PPTP login process on an encrypted WLAN by using the arpspoof

The point to point tunneling protocol (PPTP) is not secure enough for some information security policies. It's the nature of the MSCHAP V2 authentication, how it can be broken trivially by capture of the datastream, and how MPPE depends on the MSCHAP tokens for cryptographic keys.
