My thoughts on SSL: 1) Spoofing the Certificate - This is successful more often than not, and since SSL is based on trust, well bad things can happen. Remember the security conference where they spoofed bogus certs and most people, security people at that, accepted the invalid cert? This is a major weakness in the concept of SSL (not necessarily the encryption implementation, which is good, just don't get caught using weak ciphers).
I agree ...but... Lets say you use AD to force distribute client certs to all the users browser certs in your domain. I mean they get installed into the browser using either a login script or via GP. Lets further say you only allow IE on your network and you rigorously update everyone's IE and patch it etc. With the distributed cert you can at least be moderately assured that the clients are who they say they are...important if your comany uses web based applications, web SOA front-ends etc. The part of SSL everyone forgets is that of integrity....
2) Certificate Authorities - If you can own the cert authority, you could make a big profit :) Seriously, ever look at the CA's that are trusted in your browser? There are some shady places in there, and you don't necessarily just trust them, you trust however has possession of their keys...
You can use GPs to reduce the number of trusted CAs if you wish...but then you lose out on the integrity checking of some web sites on the Interweb.
3) Extended Verification Certs - Firefox just recently included this by default in version 3, and I think its a good thing, and adds a layer (albeit a small one) to the security of SSL. I like to see the green when I go to a web site (especially if its my bank ;)
Even better idea is what paypal is doing. For $5 you can get your own rsa token to be used with your pre-existing password!!! groovy!!! Jim

We have all been well trained on how to check for security. We all look down at our status bar at the bottom of the browser to make sure there is a little lock or key that assures us that everything is secure before we send anything. Well now there's a new rule to learn: data can be sent securely even if you don't see these icons of security. When you fill out an information form, or application, or login, etc. you are filling out information on one page and the information is being sent to a second page. We see the security icons when the page that collects the information is secure. The information can be sent securely if the collection page is not secure, but the page where the information is sent to is secure. This is the method we use on home page logins. If you want to assure yourself that the information you are sending is secure and you don't see a security icon, you can view the HTML source code. This may be intimidating for some, but all you have to do is search to find the word "action=." This will show you the location of the page that the information will be sent to. If you see "action='_https://?',_" you know that it is being sent securely. If you see "action='_http://',_" you know it is not secure. Information Encryption Your account information never travels the Internet without encryption protection. When you click on "login", we encrypt your Online Banking ID and password using Secure Sockets Layer (SSL) technology, the highest level of Internet security available. A secure connection is established before your ID and password are transmitted and maintained for the duration of your Online Banking session. ------------------------------------------------------------------------ _______________________________________________ Pauldotcom mailing list Pauldotcom at mail.pauldotcom.com http://mail.pauldotcom.com/cgi-bin/mailman/listinfo/pauldotcom Main Web Site: http://pauldotcom.com-- Paul Asadoorian PaulDotCom Enterprises Web: http://pauldotcom.com Phone: 401.829.9552 _______________________________________________ Pauldotcom mailing list Pauldotcom at mail.pauldotcom.com http://mail.pauldotcom.com/cgi-bin/mailman/listinfo/pauldotcom Main Web Site: http://pauldotcom.com
