Those who work in different spaces may have different definitions of the term “high voltage”. For someone working on the GPIO pins of a Raspberry Pi it might be as …read more Continue reading High Voltage Power Supply From USB
Anyone who’s done an electronics project knows the most important part of any good design is making sure to keep the magic smoke inside of all of the components. There …read more Continue reading USB Power Isolator Keeps Smoke In
I’m looking at a scenario in which it would be convenient to let 3 different cloud-rented Linux boxes (server A is the "scheduler control server", server B runs "database 1" on Oracle, & server C runs "database… Continue reading Is it a database security hazard to let multiple Oracle databases UTL_FILE the same filesystem?
If I want to run untrusted code inside a Docker container, or an untrusted Docker container for that matter, how can I restrict it?
I’d like to make sure it has no access to the host filesystem. Ideally I’d like it to have limited network… Continue reading Security of untrusted Docker containers
I recently learned about DOSBox-X. It’s basically a somewhat less awful version of the basically-abandoned DOSBox.
I currently have it installed inside a Windows 10 VM inside of my Windows 10 bare metal PC. It’s the only computer I have. I… Continue reading Is there a more convenient, yet safe, way to run DOSBox-X than I’m currently doing it?
I currently have this network setup:
As you can see, I have three devices with static ip addresses. (192.168.1.100, 192.168.1.123, 192.168.1.121) and some devices with dynamic IPs (game console etc.).
On the productivity devices I run ser… Continue reading Isolating devices within private home network [migrated]
I bought a new router to isolate devices in my network, but then I found that famous Steve Gibdson’s Three Dumb Routers episode. I have read the whole transcript but even so I didn’t get why only two routers is not enough to isolate my loc… Continue reading Why use three routers for security purposes instead of two?
I was wondering how EDR isolates hosts from the network but somehow allows the EDR solution to interact with it.
For example: how does Carbon Black EDR isolation work? You can isolate and unisolate the host from the dashboard.
This proposal concerns a strategy for isolating the permissions given to plugins in a plugin architecture. I’m looking for insight into whether this design can succeed in isolating those permissions.
Access to the entire site is controlled… Continue reading Isolating permissions available to browser JS via oauth and referer
The first ‘till-less’ Amazon Fresh store opened in London recently. Download a QR code, shop and leave with everything being charged directly to your Amazon account. Is this something that we have all been dying to do? Perhaps not today, but what … Continue reading No White Flags—the Value of Cyber Innovation at Speed and Scale
