Geneva Framework: a .NET class library called Microsoft.IdentityModel (basically it's an updated Zermatt)

Geneva Server: This is essentially ADFS v2, built on top of the Geneva Framework

Geneva CardSpace: This is CardSpace v2.

This link takes you to the "Geneva" landing page at Microsoft, where you'll find links to all of the bits, as well as the whitepaper v2. The new version of the whitepaper was co-authored by myself and a PM on the Geneva Framework team, Sesha Mani, who added a bunch of new details based on the PDC version of the framework.

The next question from the president-elect was what single policy issue he could focus on that would most help entrepreneurs.

“The most important thing he’s got to do is kick-start a huge amount of research and innovation in energy,” said Mr. Doerr, who backed Google and Amazon.com and has invested heavily in clean energy technology for the last few years.

The nation now invests less than $1 billion a year in renewable energy versus $32 billion a year in health care, Mr. Doerr said. “I think we’ve just scratched the surface in terms of clean ways to use energy, to produce energy. It’s the challenge of our generation.”

How to do that? Double the number of engineers who graduate from American universities each year to 60,000, Mr. Doerr said. Bring more women into the field, and encourage foreigners who study engineering here to stay here.

“What we do is bring foreign nationals to the world’s greatest universities. We train them, invest in them and make them go home,” he said. “What kind of national strategy is that? So I would staple a green card to the diploma.”

I'm not complaining about the fact that I can't see what I'm typing. I understand and laud that feature, because I don't want someone looking over my shoulder at the password I'm typing, and this even applies when I'm at home. I love my children, but I certainly don't want them knowing the password to my bank account!

No, what I'm bothered by is how a typical password text box behaves on a form that may incur multiple post-backs before it's finally submitted. If you use the built in ASP.NET TextBox control, it purposely does not repopulate the password text, which means if you press a button on the form that performs a post-back, or if you have a multi-page form that posts back on every step, that password disappears, and the user typically has to re-enter it. You could solve this with liberal use of ASP.NET Ajax UpdatePanels, but that adds its own complexities. I wanted a simpler solution.

So I did a little research to see what others had discovered about this problem, and I ended up deriving my own custom control from TextBox to make a much more user-friendly (and developer-friendly) TextBox control. I called it PasswordTextBox, and it acts just like a TextBox in password mode, but it retains the password while still giving the user the same level of protection the standard TextBox supplies.

My PasswordTextBox operates very simply: it stores the password in control state, and renders a series of fixed characters (with the same length as the actual password) into the text box so that it "looks" like the user's password has been rendered. Since control state is part of view state, and since view state is stored in a hidden field on the form, I encrypt the password before putting it into control state.

The result is quite nice - the user can post your form back as many times as she needs to, perhaps moving back and forth across wizard steps or tabs, and when she finally presses the "Finish" button (or whatever you call the last step of your input form), your code will be able to read the password by simply accessing the Text property on the PasswordTextBox. The user will believe that her password is sitting there on the form while she's working, as the same number of obfuscated characters will show up in the field as she typed in originally (what she doesn't know is that those characters aren't her real password anymore, but what she doesn't know won't hurt her!)

Note that to keep this simple, I used DPAPI to encrypt the password, which suited my purposes. But if you have a web farm, that won't work well at all if you don't know which machine the user's going to post back to, so you'll want to replace that with something more robust. I could see looking up the <machineKey> for entropy, as that tends to be sync'd already across the farm, but I've not yet spent the cycles to go down that road, since unfortunately all of the code for generating keys based on that config section are off limits in ASP.NET (most of the useful stuff is marked internal). I don't think it'd be that hard to do though.

Anyway, without further ado, here's the code, which you'll see is quite simple. I'd love feedback, especially if you see any glaring problems with the idea or the implementation!

public class PasswordTextBox : TextBox
{
    // unlikely that a string of these would be used for a password
    const char PasswordPlaceholderChar = '}';

    string password; // stored encrypted in control state

    {
        base.OnInit(e);
        Page.RegisterRequiresControlState(this);
    }

    {
        byte[] encryptedPassword = ProtectPassword(password);

        object baseControlState = base.SaveControlState();
        if (null == baseControlState)
            return encryptedPassword;
        else return new Pair(baseControlState, encryptedPassword);

        byte[] encryptedPassword;

        Pair pair = savedState as Pair;
        if (null != pair)
        {
            base.LoadControlState(pair.First);
            encryptedPassword = pair.Second as byte[];
        }
        else encryptedPassword = savedState as byte[];

        password = UnprotectPassword(encryptedPassword);

The best security program is at the business with the happiest customers.

There's a fine line between happy customers and playing piano in a bordello.

Sees a lot
Can tell the king he has no clothes
Can tell the king he really is ugly
Does not get killed by the king
Nice to have around but…how much security improvement comes from this ?

Changes happened faster that he was able to move
Did not read the signs
Good intentions went unfulfilled
A brutal way to ending a promising career
Sad to have around but…how much security improvement comes from this ?

Obviously these models of CISOs are not solving our information security problems. Instead Dr. Garigue points us to Charlemagne as a better model

King of the Franks and Holy Roman Emperor; conqueror of the Lombards and Saxons (742-814) - reunited much of Europe after the Dark Ages.

He set up other schools, opening them to peasant boys as well as nobles. Charlemagne never stopped studying. He brought an English monk, Alcuin, and other scholars to his court - encouraging the development of a standard script.

He set up money standards to encourage commerce, tried to build a Rhine-Danube canal, and urged better farming methods. He especially worked to spread education and Christianity in every class of people.

He relied on Counts, Margraves and Missi Domini to help him.

Margraves - Guard the frontier districts of the empire. Margraves retained, within their own jurisdictions, the authority of dukes in the feudal arm of the empire.

Missi Domini - Messengers of the King.

This is the way forward! Find software security champions in the architecture and development groups,help them understand the real security issues. They will find solutions you have not thought of. Same for DBAs, same for business analysts even. Its all about beating the bushes, education, and decentralizing security services. Specifically, he points out this important mandate for IT security

Knowledge of risky things is of strategic value

How to know today tomorrow’s unknown ?
How to structure information security processes in an organization so as to identify and address the NEXT categories of risks ?

To me this is our mandate and measure of effectiveness. Empower our customers, educate, and create business value. If I am a CISO  I don't want 20 people reporting to me who do firewall ruleset changes. I want one champion in 20 different groups - development teams, architects, DBAs, business analysts.

A concrete example, infosec can continue to go along with the herd and follow the "what everyone else is doing architecture" meanwhile developers are connecting every single thing in your business to the Web. I have been doing integration and new technology projects for a long time, and let me tell you - Change does not always create happy customers in the short run. But the chart below shows that information security is maybe more concerned with not causing waves rather than adapting.

The best security program is at the business with sustainable competitive advantage.
