Um, how does that work when they don't have your private keys? People generate a CSR which they send to a public CA like Verisign/Entrust/et al for signing. That CSR contains the RSA public key, and a matching signature created by the private key to authenticate the CSR request, but it does not contain the private key itself. Consider: openssl req -newkey rsa:2048 -keyout key.pem -out req.pem openssl req -in req.pem -text -verify -noout ls -l key.pem req.pem ...or even go through the explicit process of seeing the different data available: openssl rsa -in key.pem -pubout -out pubkey.pem openssl rsa -in key.pem -text -noout openssl rsa -pubin -in pubkey.pem -text -noout [ A CSR is about half of the size of the private+public key file; and the public key by itself is a quarter the size of the private+public key file. And even possessing key.pem doesn't disclose the private key, since there's a password needed. Unless you make an effort to export the key without a password, that is. ] Regards, -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Right, but if you were to strip-mine the earth's crust and turn all the silicon into GPU cores you still wouldn't even come close to brute-forcing AES256 before the sun turns into a red-giant. If you're saying that WPA is inadequate because weak keys can be bruteforced then the answer is don't use a weak key. If someone breaks such a key then that's pilot error, not an inherent weakness in WPA. Use a key with 100-256 bits of entropy. > What I do at home is concatenate 2 ham radio call signs of friends > that I can remember.

My key is only twice as long, but about 40,000,000,000,000,000,000,000,000,000 times better at resisting a brute force attack. > This won't actually defeat the inherent > weakness of using a pre- shared key, but it will take longer for a > simple brute force.

That's good advice for natural language pass phrases where there is only about 1 bit of entropy per character. IMO it's easier to type a high entropy password using only characters that wont need shifting on any device i.e. random lower-case letters. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

So we are talking about weak PSKs, of course with enough computing power virtually anything is crackable by brute force. What I don't get is that I thought that mac address filtering at the wireless level meant that the router would not negotiate with a mac no listed in it's table. I haven't used Kismet but you are saying that with Kismet I can infer authorized macs that are connecting to a specific access point so I can spoof one and perform my brute force attack?? Honestly I don't know much about 802.11 but if that is so it's pretty retarded and mac address filtering really a joke then. Thanks again for such detailed responses. I know all this seems all OT but it's a security issue that I don't think that many people are aware of so I haven't changed the subject to OT because of this.

I am my own CA and can generate certs that no one else has the private keys to. The problem with buying certs from a provider is the gov't has access to the private keys on demand. This was mandated back during the Clinton administration for the US. I do things like turn password auth off on my SSH and only auth via certs. Extending this to other 'connectivities' is a way to make it harder for those with no approved cert to get in. The pairing of firewall and OpenVPN together sounds interesting.

It's a matter of can you tie up the resource long enough to wait it out. Throw salting into the mix and it gets longer again. What I do at home is concatenate 2 ham radio call signs of friends that I can remember. Then I sha256 that and select from the end backwards 15 characters. This won't actually defeat the inherent weakness of using a pre- shared key, but it will take longer for a simple brute force. You should also throw in additional characters from your character set beyond just alpha/numerics. Also, my little tinkertoy i5-3570K overclocked up to 4.5GHz is just that - a toy. I can use it to generate a trace file, which I then take to work and replay it using a z196 when they occasionally allow me to play for bit. I also have rainbow tables and dictionary word-lists pregenerated for cheating. Another thing people are playing with is stuffing 4 high end video cards in a box and using them for computation. This enhances the PC platform beyond just using the CPU. There are also people doing this "in the cloud". And they will rent you compute time for a fee. :-) The pre-shared key is the weakest as compared to Enterprise. Enterprise WPA is stronger because it is a user account based system which authenticates using 802.1x via a Radius server. You can even assign certificates to user accounts and if they don't have the cert on the client they are trying to connect with, it won't. Throw Kerberos re-ticketing into the mix adds another layer to the onion. I seem to think recalling something about Kerberos re-ticketing something like every 900 seconds, or something like that. Switches and other network equipment that supports 802.1x can also filter out traffic that is not authorized. Bottom line is Enterprise is better than a simple pre-shared key. But it involves radius, dns/dhcp, windows domain controllers, active directory, a PKI infrastrucure and access points that are designed for use in this environment (and they cost more). So while it may be more secure than a simple pre-shared key, it is simply not practical for the home user as they won't have all the 'other' resources required to utilize it. -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

At work we are mostly a $MS WinderZ shop, but with Enterprise grade access points (we have Aruba's), EAP, and Radius we can extend our network Kerberos out through the wifi realm. Without going into details ( way too much/many for the scope here) I basically have an almost completely locked network which just won't allow a device on it that it doesn't recognize. It is a pain, and not perfect either by any stretch. I have more problems with printers as a result than anything else. I do have to keep an open Internet access for visitors to use, but it is separated from our main network with no path between the two. :-) This does provide better security when compared to what consumers are running at home. It is much more complex and requires expensive equipment. And even still, a really high-grade Uber hacker might still find a way in. We hire pen-tester companies about once a year, and while they haven't found any glaring holes there are some "grey" areas that we wonder if a really motivated Uber hacker spent enough time on... I have entertained on and off the idea of getting a wifi card for my FreeBSD gateway/firewall box at home to see if I could come up with something more resembling something like we have at work. It probably wouldn't be as involved, but I do think (FreeBSD as a very _capable_ and flexible OS) something could be designed that would inherently be somewhat more secure than what I see in the basic ISP home router. I have Verizon's FIOS here with an Actiontec MI424WR-Rev 3 router and I think I could do better. The alternate provider here is Comcast which mostly seems to be using Motorola Surfboard routers, but the bottom line is I don't have any problem cracking any of them.

Even in passive mode, without using active attack to speed things up I can crack a WEP key in 45 minutes easily. Doing this passively doesn't expose you.

If you are meaning that someone is using aircrack-ng to break your Wifi authentication key a firewall won't do much to stop this. -Mike [snip] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

I did that to an Acer I picked up cheap and added external antenna (not sure how much that mattered), works great all for under 300USD. I'm running OpenBSD on mine but should do any of the firewall/routers specific variants just fine. -- | _ ASCII Ribbon Eric S Pulley | ( ) Campaign Against http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Hi Alejandro. I can't speak about Hacom, but I've had excellent results with Soekris hardware. It'll run all sorts of FreeBSD-based systems. They have kit suitable for both wired and wireless networks. -- James. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
