It's generally nice that it's specific, until you hit some case where their language makes your existing solution a pain in the rear end. I know some people struggled with dated language with modern stuff like Kubernetes. At least with PCI 4.0 they introduced the customized approach instead of having to fill out a compensating controls worksheet for every single control where you're doing something different than the DSS spells out

I just kept getting brought into meetings with teams saying we want to do XYZ for PCI, and I'd have no idea if it was actually necessary or not or if they were totally misunderstanding some regulation or listening to a dumb auditor. This all came to a head when an auditor told someone in my org that we had to disallow copy/paste on all systems in scope for PCI....

I for sure dont want to work in compliance, but its a big part of the industry and I cant seem to totally ignore it anymore.

I don't remember what regulation they were quoting, but I worked for a place where IT said the failed password attempt lockout couldn't ever reset on success. So if you typed your password wrong three times, your account would be locked. Even if those three times were months apart. At a place that operated 24/7 and IT only worked day shift during the week.

I came into the infosec business via compliance, and I still kinda like it and will go back to it eventually when I'm done being a product owner for a GRC tool. I'm not really technical though, and got into this career because the entire country suddenly needed anyone who could spell GDPR in five tries.

Likely in reference to this?

Requirement 3.4.2: When using remote access technologies, technical controls prevent copy and/or relocation of PAN for all personnel, except for those with documented, explicit authorization and a legitimate, defined business need.

If you are starting from scratch and do not know, I would say first understand your PCI type and level, which will drive which requirements you need to implement.

Thereafter work like hell to be SAQ A, unless you are a service provider, in which case work like hell to descope as much as possible.

Yeah, step one of compliance should always be "what do we actually need?", followed by "what's the first step to actually getting there in a realistic way?". Way too many people start at maximum everything, to be implemented in 6 months. Without bothering anyone else. Both tech and legal types in compliance tend to forget to look at the big picture and context.
Also start by figuring out what you're actually doing in your business and then what kind of IT you are using for it. This can often take a year to get straight.

Compliance in companies comes with some problems. The people you need to do it right are probably wanting to do cooler work. The responsibility and accountability being asked to be accepted by the team is usually completely opposite of the agency they have. Winning is just status quo and losing is a giant death sentence too often.

at my previous job the company sold SOC/PCI/etc escrow/proxy services that tokenized and detokenized stuff between buyers and payment processors and merchants, for places like Wayfair and McDonalds—compliance scope reduction as a service, if you will. they were also working on a compliance sort of tool like Vanta, and that tool was to be nicely integrated into the management surfaces to all the evidence was automatically generated and monitored, meaning that our customer would find out that someone had moved out of the compliance posture approximately when it happened, rather than while they were scrambling to get the evidence together for their auditor at renewal. (mostly the idea was that we would prevent things from ending up out of posture, but there were some things that only became an issue with hindsight, IIRC)

while I was there the CSO reported to me, so I got to learn a lot more about the practical elements of compliance management and attestation for the first time, and the biggest things I learned were

  • that sort of tool could really be a huge help to a lot of small-to-mid businesses, and maybe even bigger
  • building your own PCI-scope facility is a resort of last choice, and even the obvious costs of doing it (staff and compute resources and auditor liaison, ignore engineer interruptions and additional overall system complexity!) are a lot
  • I never want to be in that business again, I’m pretty sure

also, if you’re going to be in that game, it’s easier on your sales team if 95% of your engineering staff aren’t in Ukraine, even before the war

One of my favorite sections of The Phoenix Project is the one where the new CTO, who is basically an avatar of IT competence, tells the security guy who's convinced he's the lone prophet of IT best practice that most of his pushes for better security are completely irrelevant, and walks him through all the non-IT controls that make the security guy's cherished worst case scenarios impossible. I started out feeling bad for the poor security guy, so seeing him yanked up short like that was also an eye-opener for me.

I'm dealing with a lovely device that has ancient HTTPS and modern firefox is officially reporting "gently caress You" when connecting to it.

An old Firefox 88 says the device uses TLS 1.0, TLS_RSA_WITH_3DES_EDE_CBC_SHA 112Bit. Which, yeah... But old firefox could connect with the about :config tls deprecated setting on. The cert is RSA 1024.
Modern Firefox version 100+ refuses outright regardless of settings, I'm assuming everything has been compiled out. openssl won't even handshake enough to report literally anything even with -security_debug_verbose switch.

The device's management interface is already on a VLAN, but even then I question going to http. Or maybe these algorithms are so absolutely pathetic these days that it's effectively no effort compared to http.

Is there some setting in modern firefox or chromium I'm missing? Building my own version of something? A VM with an old version of firefox that only connects to that VLAN and never gets updated forever?

This is why I have a Win7 VM with IE 11 a bunch of old USB stick non-install versions of chrome and Firefox for this reason. Comes in real handy when working with medical stuff.

This is slowly getting better with more wireless stuff like Bluetooth sensors and such. Much of the outdated stuff is because of stringent regulations of "electromedical" devices, that is, stuff connected to the mains on one side, and to a patient on the other. Certifying that gear is expensive as gently caress, so once a hw-configuration is certified it will be static for the lifetime of the device, and not be compatible with newer OSes and such. But with Bluetooth you can air gap the patient from the mains, and thus run the sw on newer devices with less hassle while the patent sensors runs on batteries.

This might be more appropriate for a mobile phone thread, but it's also security related. I've heard that it's a good idea to disable wifi when you're away from home, because big box stores like Walmart have their own APs setup to log hotspot scans from mobile devices. Who knows what that data is used for, but presumably, over time, companies could use it to figure out that I buy frozen pizza and lube every other Friday.

Is disabling wifi on mobile devices when you leave home still sound advice if you're paranoid and/or privacy-minded? On iOS, I have an option in the control center to "disconnect nearby wifi until tomorrow." Is that sufficient, or should wifi actually be disabled in the settings? Or is this all a bunch of nonsense?

Windows Phone had location-aware Wi-Fi toggles; maybe iOS has the same? Either way I spent a good thirty seconds wondering how the lube and pizza go together so I dunno what Walmart’s going to infer without more spending than your ad tracking brings in.

I know that iOS has the private MAC address option, but does that kind of tracking use MAC addresses? I recall reading somewhere that it could also use SSIDs, so that if your home network's SSID is "ABC" an AP that is collecting data would log when a phone entered the area and scanned for "ABC". Do phones even send out SSID names when they scan for wifi?

Yeah, I don't really think Target or Aldi care that much about the pittance that my broke rear end spends on groceries, but I'm also sure that they'd love to send me mailers targeting my specific behavior and spending habits if they could do it cheaply.

They did a decade or so ago (one of our demos used an SDR to de-anonymize phones by doing exactly that) but I haven't checked on it recently. If you're organized enough to do that, though, you can just set up an imsi catcher. Walmart is probably not doing that, and anyone who is isn't interested in you.

are you talking about connecting to unadvertised SSIDs? I don’t recall anything in the WiFi scanning protocol that has an SSID outbound from the scanning device

E: I forgot about directed probes, of course. I thought they were only used for connecting to unadvertised SSIDs, but that could be incorrect!

I imagine that's how it worked, yeah; the phone was sending out probe requests for its familiar but un-advertised networks and my device (with the manual I didn't read, about the spec I also did not read) picked 'em up so I could see things like MARRIOTT 346 from among the consenting few who'd left their phones on.

iOS won't use their native MAC by default but it will keep using the same generated MAC on a previously joined SSID, which, if joined by a user specific password or a user-bound session out of a captive portal, could be used by the infrastructure owner to track customers. Yes, i know this is deep tinfoil territory but it's still a weakness of the system.

No, this hasn't been a thing for a long time with MAC randomization.

Some APs could be broadcast in scans but people really misinterpreted how that worked. The only APs that were ever broadcast by your phone were for networks with hidden APs (which are dumb and you probably don't have any saved, and if you do -- don't).

Considering the store also has video recordings of your face while you sample the lube in aisle 5, you don't need to worry. Even if they have your mac address, that basically only tells them that the same guy keeps coming in every Friday, they presumably don't have anything to link it to. Unless of course you allow Google to track your location, in which case why are you not worried about that way more?

Because that's less likely to be abused than Walmart (or really the company they hire to do it) linking you and giving that info to others?

I've always loved this one because the people who thought they were "hiding" their SSID actually make their devices scream it out everywhere they go. And of course still not hiding anything around the actual network either.
