You have no idea. At the big banquet dinner they had, they did a sing-a-long for some theme song or anthem they had written for themselves. It felt *very* culty.

Back in the day (2005-2013), I was focusing on AI content. I got into cybersecurity largely because the university I was teaching at wanted to offer a class on cybersecurity and ethics. I wanted to teach the ethics.
I stayed because I saw where AI was going and cybersecurity felt way less evil. I had some vague hope at the time that the field might be able to prevent the worst abuses.
The specific trigger for me jumping ship was a data mining conference (circa Snowden, don't recall the specific year) in which I watched a panel of AI researchers bemoan the fact they couldn't literally strap biometric sensors to children 24/7.

I don't think we are.
I think the problem the distinction between "legitimate engineering practices" and "legitimate software engineering practices."
The point that we're raising here is that most (maybe very large chunks) of the software engineering follow bad engineering practices, which have been normalized in the software industry. The root cause is, of course, that real engineers have liability and that shifts organizational risk tolerance.
"If you don't know how it works or it's wrong sometimes" is bad engineering.
For example, go try to talk to and mechanical engineer or electrical engineer into including something they don't understand or that could have, say, a 20% error rate into their designs.

2026-07-09 21:08:26 UTC

Two additional quick thoughts.
One: The reason it's not possible with AI (assuming LLMs) is the stochastic nature of these systems.
Two: This, of course, hinges upon a definition of "safe" and establishing risk tolerance metrics.

You missed a couple of words there. "legitimate engineering practices". Note that it doesn't say "legitimate software engineering practices".
One of those legitimate engineering practices is a verifiably safe design. That, by definition, is not possible with AI.

This is the single biggest reason we don't have much cloud content in our curriculum. The assessed risk of overspend is too high and there's no reasonable controls we can implement without adding too much administrative overhead.

Back in grad school (2006ish, I think), I worked with an undergrad student on a project adjacent to my thesis. In addition to being a straight-A CS major, he ran the student jazz band. Given that our school was known for their music program and the jazz band at the time was the cream of the crop, I asked why he wasn't doing that, instead of CS.
He told me that he liked music and he didn't like computers much, so it made more sense for a career.
I think about that a lot.

Oh, yeah, definitely. Our (purely) offensive classes are "Penetration Testing Frameworks and Methodologies" and "Offensive Security Engineering" (red team tool dev).
I would say... somewhere between many/most of our classes have either an ethics component or a societal impact component, but we don't have a full-on class in the major (taught by from the security department) dedicated to ethics.

Most philosophy majors have a debate class titled something like "Contemporary Moral Issues" in which students research and debate some classically controversial issue (civilly).
Tech desperately needs an adaptation of this class.

So, the argument seems to be that acceleration of attacks (and, I assume, increased success rate) necessitate higher levels of automation. The HTB success rates, in particular, are what seem to be raising alarm bells from those on the practicioner side.
The argument is, roughly, that IF we're about to be inundated by an influx of highly skilled red-team agents, THEN we need blue team agents in the loop that are capable of responding with similar speed.
That strikes me as reasonable logic. I'm not sure I'm willing to grant the antecedent at this point, but the structure of the IF-THEN strikes me as rational.
Or maybe we could just turn all the computers off and throw them out of whatever window is nearest.

2026-04-21 19:20:27 UTC

- reply

Which, just to put a bow on the conversation, seems to be the point of both pieces.
If you accept their premise about attack speed accelerating (not sure I do,.but it *is* a reasonable hypothesis), then it's probably time to actually get those things done... And to do that at a fast enough pace, one probably needs agents (and the restrictions outlined).

One of my hotter professional takes is that cybersecurity is no longer a fast-moving industry and that we've had a pretty solid notion of how to do security right for at least a decade.
Our problems these days are more about making sure those things get done than in figuring out what the right thing to do is.

I agree, but what are the chances at getting a substantive regulatory framework or product liability regulations in this space?
I'm using "engineering" as shorthand for design/implementation since, as we all know, most of what tech does really shouldn't be called engineering.
There's a few interesting nuggets in there, though. In addition to "The boring basics like asset management, least privilege, and network segmentation really do matter", the relative importance of penetration testing (declining), detection engineering (increasing), and the shift towards "assume you're compromised" all strike me as reasonable points.

2026-04-21 16:33:27 UTC

The argument that both pieces seem to be putting forward is that they expect attackers, in the future, to be leveraging AI/LLMs to increase the pace of attacks to a point where will no longer be feasible for humans to play the same role in the incident response loop that they currently play.
I'm not sure I accept that, but it's a clear hypothesis that be tested for correctness with data. It's also not rooted, as you say, in happier vibes.
The set of controls proposed by both appear to differ (I only skimmed the one you posted). Mubix's piece focuses on two attributes, one of actions and one of agents.
Agents need to have minimally constrained scope (so, least privilege applied to agents). The set of actions they are permitted to take should also only be actions that are reversible. The rest of the document outlines engineering best practices that absolutely need to be in place (and, as we know, often aren't) in order to facilitate those.

2026-04-21 16:17:48 UTC

That said, a non-trivial amount of the recommendations of both are, in z nutshell, "Get your act together and finally do the basics right."

Ehhh, the CISO to current practitioner ratio is low, but there's definitely folks on there from a practitioner background. It also echoes many of the same points as the ones Mubix made here:
https://infosec.exchange/@mubix/116415117902139733
I haven't drunk the proverbial KoolAid, but I find interesting that both position papers are a) providing reasonably precise (and testable) hypotheses about how they are anticipating the threat landscape will change over the medium term and b) describing reasonably precise control sets needed to mitigate that risk (as well as the risk caused by the technical debt accrued by the lack of oversight of past AI investments).

I've also wondered, to some extent, how much of this is the result of "main character syndrome", for lack of a better phrase.
People want to believe they're doing something wild, exciting, and innovative. So much of cybersecurity, however, is glorified accountancy, tradesman (plumbing/electrical/etc), and janitorial work.
It's hard for folks to wrap their head around the fact that their jobs are much more like that of the folks in Office Space than V from Cyberpunk.

I suppose we'll see. Given the unreliability of US foreign and security policy, we've seen other sectors shift away from American produced goods. Notably, the auto industry.
I would think that some countries (Denmark, for example) might be wondering if it's time to shift technical infrastructure away from US goods too. Hasn't there been some of this happening in the cloud space already?
I imagine the primary problem here is the lack of alternatives in the router space.

I see applications in RPGs. Imagine Skyrim or Baldurs Gate without canned dialogue. That said, the replay value of those games would skyrocket, probably hurting sales of other games. On the ethical side, compensation for voice actors would be a problem.

I used to teach quite a lot of courses that covered ethics as it applies to technology. This was, to honest, my gateway into security.

Friend, I think you have far too high of an opinion about university administrators. A few things:
1) Most universities are schools attached to hedge funds by way of the endowment. In most schools, the person with the most practical power on campus isn't the president or the board, it's the CFO/VP for Finance/<insert similar title here>.
2) US universities can be held hostage with the threat of withholding financial aid money. Suppose there's a threat: "Remove diversity or you can't receive student loans/pell grants". Without that income, most universities wouldn't be able to make payroll. There might be a delay by a semester or two while operating budgets are shuffled around and there are massive layoffs, but that's the ballgame. They'd be relying on research funds and money from their foundation.. but that really doesn't go very far.
This really sucks, but I strongly suspect no universities are coming to save anyone.

Yeah. This *is* a C programming class too, for what it's worth. It's the third class in our programming sequence (Python, then OOP w/ Java).
I very intentionally frame the class as "Our goal here is to learn to think like the compiler, and we're going to take away all the cool programming tools you had in your first two classes."

Yeah. This is a problem I'm really noticing in my year 2 course right now. Students are relying on the AI to do any kind of critical thinking, even things like basic debugging.
It's not uniform across all students, but it's a real problem when they're asked to do something the AI isn't good at. For example, my course spends a lot of time covering topics like memory management, process management, etc... along with the syscalls used for it.
But, the course is intended to prep students for understanding exploit development/reverse engineering, so we use Windows, not Linux (like all the other OS courses out there). ChatGPT ain't great at writing code for Windows.
Interestingly, it usually fails on the same stuff I do in my first pass, like all the wonky string typecasting needed. It's all stuff there's not a ton of resources for. There's maybe 1 or 2 useful books and the rest of the content lives in TechNet articles. There's not even a ton on Stack Overflow. Not enough for ChatGPT to really work with.
I'm encountering students that really struggle with the debugging process. Instead of "Compile, get an error, research that error, figure out the problem, fix the problem, add the next bit of functionality", I'm seeing students just throw the whole thing into ChatGPT (maybe) with the error message and expect ChatGPT to fix it.

My best story on that - I was red teaming a student competition during which the student teams could attack each other too.
One team of students blew out Ansible that replaced every binary in System32 with a simple executable that just printed 'No'.
The pro red team spent, like, half the day tracking down why Cobalt Strike was telling us 'No' thinking it was a permissions problem.
