🎖️ CISA (US Cybersecurity & Infrastructure Security Agency) pleged continued support of the CVE program, an important message after April’s de-funding scare.

🙂 The AppSec Village at DEFCON33 ran, with many engaging and educational talks. Keep an eye on the YouTube channel, but be patient – it can take a few months.

Even “Day 0” at #BHUSA is nice. Get settled, get badge when it’s slow, meet up with some folks I don’t get to see that often, get some grub.

Who’s around tomorrow to hang out? Drop me a DM or reply (or if you have my Signal, hit me there)!

Runtime security is important. But it's inherently reactive — it's a back up for proactive controls. Get to a point of acceptable risk before deploy; use runtime to deal with risks that are hard to detect before you ship, or that arise after deployment (such as newly-reported vulnerabilities).

If you're relying on runtime scanners alone for your vuln management, you're essentially saying "my org can patch so quickly and effectively that I'm confident we'll find and fix live risks before attackers do". That is *wild* to me.

Wow, thanks Spotify, that's a very helpful and well-considered error dialog /s

Security Champions are empowered to make routine security decisions, educated to help their teams follow the security policies and programs that apply to them, and relied upon to provide valuable feedback to the security teams about places where the program needs improvement or adjustment.

Security Champions aren't "bonus staff" for the security team. They're trusted partners in building a security culture. As a bonus, you get a network of trained rapid-responders when there's a high-priority issue.

And then leaders are confused that this fails, and ultimately decide that champions programs don't work.

A Security Champions Program should work more like a Safety Warden program. The goal is to create a network of people who act as liasons between their teams and the professional security teams.

Did your Security Champions program fail, or did your org do something silly and ill-advised and stick a "Security Champions Program" label on it? Way too many orgs try to "Shit Left", dumping security accountability on team members, declaring them "Champions", and failing to provide support.

I went that route last year; even for gaming, Linux has been just solid and very low problems (went Manjaro on my main desktop and Laptop, and the kids’ gaming rigs)

Very cool that the #CheckmarxOne platform for Government has now achieved #FedRAMP High Ready! Amazing work across multiple teams to coordinate this process. AFAIK we're the only AppSec platform addressing the High impact level for FedRAMP. marketplace.fedramp.gov/products/FR2...

Practically speaking, if you want to do business with the US government, you're still going to want to meet those requirements unless you have a fairly narrow scope of business that only includes agencies that won't adopt such requirements.

Orgs no longer need to universally supply #SBOM docs or produce machine-readable #SSDF attestations. BUT, it doesn't end current requirements or stop agencies from acting on their own. This isn't really surprising given the administration's priorities and related positions.

I haven't digested the whole new Cybersecurity EO, but I did skim for AppSec-relevant stuff and it seems like it rolls back some of the standardization push. The backing off from standardization across the whole federal space is disappointing from a security and safety standpoint.

False Positive or Noise? Smart security teams still get this wrong Before you report a security finding as a "false positive", make sure you distinguish between FPs and noise. The difference matters, and more people get it wrong than you'd expect

#InfoSec organizations (and especially #ProdSec and #AppSec) have a big challenge ahead of them to stay out in front of the rapidly-changing threat landscape for #LLM. We can't rely on providers like Hugging Face to solve the problem for us.

Spending today at #Secure360 — if there's one thing I can request, it's for speakers to repeat (or at least summarize) audience questions before answering.

With Star Wars trending thanks to Andor Season 2, I see we're again having the "stop making $THING political!!" discourse from people who somehow managed to miss how deeply $THING has been overtly political since its inception

New work! Andor… I love this series, I love this franchise - I’m so excited and humbled at the opportunity!

Thank you Star Wars, Disney and Poster Posse! #Andor

So the whole #easyjson kerfluffle is like a big nothing for almost everyone, right? Like it's 99.9% "Russia scary" based speculation about something that could possibly happen in the future if a bunch of assumptions are correct.

I know I'm increasingly in the minority, but I can't stand learning most things from videos. If you must share information by making a video, please *please* also make it available to read.
