How To Crack Pre Shared Key Sonicwall

10

Jan 15, 2013  The pre-shared key is known as the 'Shared Secret' within the settings. As soon as you change this key all of your existing clients will be unable to connect as they will all now have the wrong key. Boujou 5.0.2 crack.

This is one of many VPN tutorials on my blog. What exactly do you mean? A kind of expiration timer that automatically blocks the VPN if the same PSK is used for x days? This must be a firewall feature, but I have not heard of a feature like that. Or do you mean whether it is a security issue if the PSK is never changed?

Well, as long as both sites use static IPs, and as long as the PSK is complex enough, there is no reason to change the PSK. However, if it is never changed, this is not “good” either. Maybe it is exposed through another way (social engineering, etc.).

So, in my opinion, a PSK change every 3-5 years is a good choice. But even more it is relevant to check every 3-5 years if appropriate security algorithms (ciphers) are used for phase 1 and phase 2. If you are still using “no-DH” or “DH-2”, this is NOT secure anymore.

That is: Change your PSK every 3-5 years AND review your P1 and P2 proposals.;). Hello, What do you mean by “Generate a new PSK for every VPN tunnel”? Do the communicating parties need to exchange a nonce/random everytime (with which they generate a new PSK)? Imagine that we have several embedded devices that they need to authenticate whenever they want to communicate with each other. Do you think that authentication with PSK is a good idea? Do you know of any mechanism with which we can securely distribute the PSK to all these devices?

Or should we configure the PSK seperately on each device? Well, it depends.

If you have multiple embedded devices, you should consider using authentication via certificates. There are options to distribute certificates automatically. Concerning “Generate a new PSK for every VPN tunnel”: If you are a company that has 10-50 static VPN tunnels that do not change that often (i.e., the IP addresses of the partners do not change that ofen), you can use PSKs for authentication. The PSK must be configured only once (!) during the setup of the VPN. It must not be changed later on. But if you have a few VPNs coming from dynamic IP addresses, I do not recommend to use the same PSK for these VPNs, but to use a different/new PSK for each of these. If one PSK is exposed, it can be deleted without the need for a change of the PSKs from the other VPNs.

Can you speak to the plausibility of an attack on a main-mode Phase 1 Internet Key Exchange IF the attacker can snoop on the traffic and if s/he ALSO knows the pre-shared key? I’m thinking that in thinking that in main-mode, If one were 100% certain that your IP address were not being spoofed by an attacker (impossible, I know, but this is a thought experiment), that absolutely NO phase 1 key would be needed at all, is that right? The Diffie Hellman key exchange itself guarantees that the key is exchanged privately. The key, as you say, is only used for validating the identity of the remote parties. Hey Karlfife. I am not sure whether I am understanding your question correctly.
