Spend all you want. Buy the most advanced products, and then most expensive services to manage them. I have never seen a company that improved their security by buying it.
Pentests work.
We regularly see attacks extorting tens of millions of dollars from major multinationals like Citadel. Is the cost of breaching their systems in excess of ten million dollars (which would net you a nice fat profit against multiple tens of millions extorted)? You get a team of 10 professionals for 1-3 years and you can not breach their systems?
That is the minimum standard of adequate against commonplace, prevailing threats for large multinationals. Even that ignores the fact that major corporations are frequently attacked by state actors, so really the minimum standard for protection against expected threats should include those as well, but I will leave that aside for now since the overwhelming sentiment is that protection against state actors is so utterly hopeless it is not even worth mentioning.
For that matter, can you point to literally any system in the entire world that is positively demonstrated (absence of evidence is not evidence of absence) to have reached that standard?
It always has been, it's just now the state actors are more and more active (and visibly so).
The problem is getting the decision makers to care. And/or changing the process to at least consider quality as an important factor even if velocity is preferred(and featuritis has taken over).
Story time. In one gig I had, a couple of weeks into it I discovered that AWS keys to the production data in the S3 buckets were being exposed on the client side(an SPA). Those keys would give you access to the data for all the clients on that platform. So I figured I'd do "the right thing" and told my manager(the CTO) who said something along the lines of "yeah that sounds serious" and asked me to talk to the CEO who wrote that code. At this point, I was still expecting that I might be wrong or at least being told that it was written in a rush or something and thank me for pointing it out. The CEO just dismissed it as being "temporary production keys" and closed down the conversation. Suffice it to say that I was not the CEO's favorite person moving forward.
I would be very happy if you right about this.
Whitelisting is usually easier than blacklisting, and not devloping brittle features where errors have security implications is usually easier than spending money on security after the fact. However not developing features is not something we as an industry is good at. Github Actions perhaps being the most recent example of this.
isnt pentesting supposed to generate tickets to fix vulnerabilities?
