What I Learned Watching All 44 AppSec Cali 2019 Talks

OWASP AppSec California is one of my favorite security conferences: the talks are great, attendees are friendly, and it takes place right next to the beach in Santa Monica. Not too shabby 😎

One problem I always have, though, is that there are some great talks on the schedule that I end up missing.

So this year I decided to go back and watch all 44 talks from last year’s con, AppSec Cali 2019, and write a detailed summary of their key points.

If I had realized how much time and effort this was going to be at the beginning I probably wouldn’t have done it, but by the time I realized that this endeavor would take hundreds of hours, I was already too deep into it to quit 😅

What’s in this Post

This post is structured as follows:

  • Stats: Some high level stats and trends- which talk categories were most popular? Which companies gave the most talks?

  • Overview of Talks: A quick rundown of every talk in a few lines each, so you can quickly skim them and find the talks that are most directly relevant to you.

  • Summaries: detailed summaries of each talk, grouped by category.

Note the navigation bar on the left hand side, which will enable you to quickly jump to any talk.

Feedback Welcomed!
If you’re one of the speakers and I’ve left out something important, please let me know! I’m happy to update this. Also, feel free to let me know about any spelling or grammar errors or broken links.

If you find DevSecOps / scaling really interesting, I’d love to chat about what you do at your company / any tips and tricks you’ve found useful. Hit me up on Twitter, LinkedIn, or email.

Stats

In total, AppSec Cali 2019 had 44 talks that were a combined ~31.5 hours of video.

Here are the talks grouped by the category that I believed was most fitting:

We can also see that containers and Kubernetes were fairly popular topics (3).

Some things I found surprising were how many talks there were on threat modeling (4) and account security (4), and how there were only 3 primarily cloud security-focused talks. Perhaps the biggest surprise was that there were 3 talks on securing third-party code, with Slack discussing the steps they took to evaluate Slack bots and Salesforce discussing the review process on their AppExchange.

Here we see Netflix crushing it: they had presence on a panel, gave one of the keynotes, and collectively had 3 other talks. And of these 5 talks, 3 made my top 10 list. Not too shabby 👍

In second place, we see Segment coming in strong!

Netflix, Segment, and Dropbox were on at least one panel, while the rest of the companies listed had separate talks.

Overview of Talks

For your ease of navigation, this section groups all of the talks by category, gives a high description of what they’re about, and provides a link to jump right to their summary.

Note: the talks in each category are listed in alphabetical order, not in my order of preference.

My Top 10 Talks

This section lists my top 10 favorite talks from AppSec Cali 2019 ❤️

It was incredibly difficult narrowing it down to just 10, as there were so many good talks. All of these talks were selected because they are information-dense with detailed, actionable insights. I guarantee you’ll learn something useful from them.
