There are certain things people want and will pay for. There are things they want and won’t. If we look at security it’s pretty clear now that security is one of those things people want, but most won’t pay for. The insane success of Let’s Encrypt is where this thought came from. Certificates aren’t new, they used to even be really cheap (there were free providers, but there was a time cost of jumping through hoops). Let’s Encrypt make the time and actual cost basically zero, now it’s deployed all over. Depending who you ask, they’re one of the biggest CAs around now, and that took them a year? That’s crazy.
Nobody is going to say “I don’t want security”. Only a monster would say such a thing. Now if you ask them to pay for their security, they’ll probably sneak out the back door while you’re not looking. We all have causes we think are great, but we’re not willing to pay for them. Do I believe in helping disadvantaged youth in Albania? I TOTALLY DO! Can I donate to the cause? I just remembered I left the kettle on the stove.
Currently most people and groups don’t have to do things securely. There is some incentive in certain industries, but fundamentally they don’t want to pay for anything. And let’s face it, the difference between what happens if they do something or don’t do something (let’s say http vs https), it going to be minimal. There are some search engine rules now that give preference to https, so there’s incentive. With a free CA, now there’s no excuse. A great way forward will be small incentives for being more secure and having free or low cost ways to get those (email is probably next).
How can we make more security free?
Better built in technologies work, look at things like stack canaries, everyone has them, almost everyone uses them. If you look at Wikipedia, it was around 2000 that major compilers started to add this technology. It took quite a fair bit of time. Phrack 49, which brought stack smashing to the conversation, was published in 1996, we didn’t see massive update in stack protections until after 2000. Can you imagine what four years is like in today’s Internet?
If we think about what seems to be the hip technologies today, a few spring to mind.
- Code scanning is currently expensive, and not well used.
- Endpoint security gets plenty of news.
- What do you mean you don’t have an SDLC! I am shocked! SHOCKED!
- Software Defined EVERYTHING!
- There are also plenty of authentication and identity and twelve factor something or other.
The list an go on nearly forever. Ask yourself this. What is the ROI on this stuff? Apart from not being able to answer, I bet some of it is negative. Why should we do something that costs more than it saves? Just having free security isn’t enough, it has to also be useful. Part of the appeal of Let’s Encrypt is it’s really easy to use, it solves a problem, it’s very low cost, and high ROI. How many security technologies can we say this about? We can’t even agree what problems some of this stuff solves.
Here’s an easy rule of thumb for things like this. If you can’t show a return of at least 10x, don’t do something. We get caught in the trap of “I have to do something” without any regard for if it makes sense. A huge advantage of demanding measured returns is it makes us focus on two questions that rarely get asked. The first and most important is “how much will this cost?” we’ve all seen runaway projects. The second is “what’s my real benefit”. The second is really hard sometimes and will end up creating a lot of new questions and ideas. If you can’t measure or decide what the benefit is to what you’re doing, you probably don’t need to be doing that. A big part of being a modern agile organization is only doing what’s needed. Security ROI can help us focus on that.
At the end of the day stop complaining everything is terrible (we already know it is), figure out how you can make a difference without huge cost. Shaking your fist while screaming “you’ll be sorry” isn’t a strategy.
