The Security of the Fortuna PRNG

Providing random numbers on computers can be very difficult. Back in 2003, Niels Ferguson and I designed Fortuna as a secure PRNG. Particularly important is how it collects entropy from various processes on the computer and mixes them all together.

While Fortuna is widely used, there hadn’t been any real analysis of the system. This has now changed. A new paper by Yevgeniy Dodis, Adi Shamir, Noah Stephens-Davidowitz, and Daniel Wichs provides some theoretical modeling for entropy collection and PRNG. They analyze Fortuna and find it good but not optimal, and then provide their own optimal system.

Excellent, and long-needed, research.

Co3 Systems at the RSA Conference

Co3 Systems is going to be at the RSA Conference. We don’t have our own booth on the show floor, but there are four ways you can find us. Monday, we’re at the Innovation Sandbox: 1:00–5:00 in Moscone North. At the conference, we’re in the RSA Security booth. Go to the SecOps section of the booth and ask about us. We’ll be happy to show you our incident response coordination system. We’re hosting an Incident Response Forum on Tuesday night with partners HP, CSC, and iSight Partners for select companies and individuals. We also have a demo suite in the St. Regis Hotel. E-mail me if you want to get on the schedule for either of those two.

Today I Briefed Congress on the NSA

This morning, I spent an hour in a closed room with six members of Congress: Rep. Lofgren, Rep. Sensenbrenner, Rep. Bobby Scott, Rep. Goodlatte, Rep. Mike Thompson, and Rep. Amash. No staffers, no public: just them. Lofgren had asked me to brief her and a few Representatives on the NSA. She said that the NSA wasn’t forthcoming about their activities, and they wanted me—as someone with access to the Snowden documents—to explain to them what the NSA was doing. Of course, I’m not going to give details on the meeting, except to say that it was candid and interesting. And that it’s extremely freaky that Congress has such a difficult time getting information out of the NSA that they have to ask me. I really want oversight to work better in this country.

Surreal part of setting up this meeting: I suggested that we hold this meeting in a SCIF, because they wanted me to talk about top secret documents that had not been made public. The problem is that I, as someone without a clearance, would not be allowed into the SCIF. So we had to have the meeting in a regular room.

EDITED TO ADD: This really was an extraordinary thing.

Twitter Users: Please Make Sure You're Following the Right Feed

I have an official Twitter feed of my blog; it’s @schneierblog. There’s also an unofficial feed at @Bruce_Schneier. I have nothing to do with that one.

I wouldn’t mind the unofficial feed—if people are reading my blog, who cares—except that it isn’t working right, and hasn’t been for some time. It publishes some posts weeks late and skips others entirely. I’m only hoping that this one will show up there.

It’s also kind of annoying that @Bruce_Schneier keeps following people, who think it’s me. It’s not; I never log in to Twitter and I don’t follow anyone there.

So if you want to read my blog on Twitter, please make sure you’re following @schneierblog. And if you are the person who runs the @Bruce_Schneier account—if anyone is even running it anymore—please e-mail me at the address on my Contact page. I’d rather see it fixed than shut down, but better for it to be shut down than continue in its broken state.

I’ve Joined Co3 Systems

For decades, I’ve said that good security is a combination of protection, detection, and response. In 1999, when I formed Counterpane Internet Security, I focused the company on what was then the nascent area of detection. Since then, there have been many products and services that focus on detection, and it’s a huge part of the information security industry. Now, it’s time for response. While there are many companies that offer services to aid in incident response—mitigation, forensics, recovery, compliance—there are no comprehensive products in this area.

Well, almost none. Co3 Systems provides a coordination system for incident response. I think of it as a social networking site for incident response, though the company doesn’t use this term. The idea is that the system generates your incident response plan on installation, and when something happens, automatically executes it. It collects information about the incident, assigns and tracks tasks, and logs everything you do. It links you with information you might need, companies you might want to talk to, and regulations you might be required to comply with. And it logs everything, so you can demonstrate that you followed your response plan and thus the law—or see how and where you fell short.

Years ago, attacks were both less frequent and less serious, and compliance requirements were more modest. But today, companies get breached all the time, and regulatory requirements are complicated—and getting more so all the time. Ad hoc incident response isn’t enough anymore. There are lots of things you need to do when you’re attacked, both to secure your network from the attackers and to secure your company from litigation.

The problem with any emergency response plan is that you only need it in an emergency. Emergencies are both complicated and stressful, and it’s easy for things to fall through the cracks. It’s critical to have something—a system, a checklist, even a person—that tracks everything and makes sure that everything that has to get done is.

Co3 Systems is great in an emergency, but of course you really want to have installed and configured it before the emergency.

It will also serve you better if you use it regularly. Co3 Systems is designed to be valuable for all incident response, both the mundane and the critical. The system can record and assess everything that appears abnormal. The incident response plans it generates make it easy, and the intelligence feeds make it useful. If Co3 Systems is already in place, when something turns out to be a real incident, it’s easy to escalate it to the next level, and you’ll be using tools you’re already familiar with.

Co3 Systems works either from a private cloud or on your network. I think the cloud makes more sense; you don’t want to coordinate incident response from the network that is under attack. And it’s constantly getting better as more partner companies integrate their information feeds and best practices. The company has launched some of these partnerships already, and there are some major names soon to be announced.

Today I am joining Co3 Systems as its Chief Technology Officer. I’ve been on the company’s advisory board for about a year, and was an informal adviser to CEO John Bruce before that. John and I worked together at Counterpane in the early 2000s, and we both think this is a natural extension to what we tried to build there. I also know CMO Ted Julian from his days at @Stake. Together, we’re going to build the incident response product.

I’m really excited about this—and the fact that the company headquarters are just three T stops inbound to Harvard and the Berkman Center makes it even more perfect.

Yes, I'm Leaving BT

The Register reported that I am leaving BT at the end of the year. It quoted BT as saying:

We hired Bruce because of his thought leadership in security and as part of our acquisition of Counterpane. We have agreed to part ways as we felt our relationship had run its course and come to a natural end. It has nothing to do with his recent blogs. We hired Bruce because of his thought leadership in security, not because we agree with everything he says. In fact, it’s his ability to challenge our assumptions that made him especially valuable to BT.

Yes, it’s true. And contrary to rumors, this has nothing to do with the NSA or GCHQ. No, BT wasn’t always happy with my writings on the topic, but it knew that I am an independent thinker and didn’t try to muzzle me in any way. I’m just ready to leave. I spent seven years at BT, and seven years at Counterpane Internet Security, Inc., before BT bought us. It’s past time for something new.

As to what comes next: answer cloudy; ask again later.

More news here. And a Slashdot and Hacker News thread.
