Everything you know about security is wrong, stop protecting your empire!

Last week I kept running into old school people trying to justify why something that made sense in the past still makes sense today. Usually I ignore these sort of statements, but I feel like I’m seeing them often enough it’s time to write something up. We’re in the middle of disruptive change. That meansContinue reading “Everything you know about security is wrong, stop protecting your empire!”

Return on Risk Investment

I found myself in a discussion earlier this week that worked its way into return on investment topics. Of course nobody could really agree on what the return was which is sort of how these conversations often work out. It’s really hard to decide what the return on investment is for security features and products.Continue reading “Return on Risk Investment”

What does security and USB-C have in common?

I’ve decided to create yet another security analogy! You can’t tell, but I’m very excited to do this. One of my long standing complaints about security is there are basically no good analogies that make sense. We always try to talk about auto safety, or food safety, or maybe building security, how about pollution. There’sContinue reading “What does security and USB-C have in common?”

Security Advice: Bad, Terrible, or Awful

As an industry, we suck at giving advice. I don’t mean this in some negative hateful way, it’s just the way it is. It’s human nature really. As a species most of us aren’t very good at giving or receiving advice. There’s always that vision of the wise old person dropping wisdom on the youthContinue reading “Security Advice: Bad, Terrible, or Awful”

Looks like you have a bad case of embedded libraries

A long time ago pretty much every application and library carried around its own copy of zlib. zlib is a library that does really fast and really good compression and decompression. If you’re storing data or transmitting data, it’s very likely this library is in use. It’s easy to use and is public domain. It’sContinue reading “Looks like you have a bad case of embedded libraries”

The art of cutting edge, Doom 2 vs the modern Security Industry

During the holiday, I started playing Doom 2. I bet I’ve not touched this game in more than ten years. I can’t even remember the last time I played it. My home directory was full of garbage and it was time to clean it up when I came across doom2.wad. I’ve been carrying this fileContinue reading “The art of cutting edge, Doom 2 vs the modern Security Industry”

Does "real" security matter?

As the dumpster fire that is 2016 crawls to the finish line, we had another story about a massive Yahoo breach. 1 billion user accounts had data stolen. Just to give some context here, that has to be hundreds of gigabytes at an absolute minimum. That’s a crazy amount of data. And nobody really cares.Continue reading “Does "real" security matter?”

Airports, Goats, Computers, and Users

Last week I had the joy traveling through airports right after the United States Thanksgiving holiday. Now I don’t know how many of you have ever tried to travel the week after Thanksgiving but it’s kind of crazy, there are a lot of people, way more than usual, and a significant number of them haveContinue reading “Airports, Goats, Computers, and Users”

The Economics of stealing a Tesla with a phone

A few days ago there was a story about how to steal a Tesla by installing malware on the owner’s phone. If you look at the big picture view of this problem it’s not all that bad, but our security brains want to make a huge deal out of this. Now I’m not saying that Tesla shouldn’tContinue reading “The Economics of stealing a Tesla with a phone”
