A manager invited me to try and test the physical security of his office door lock (by non-destructive means, i.e. not ramming the door down). I found that since the door opened from inside by a handle (which automatically u… Continue reading resource on physical security that calls out doorknobs as being more secure than door handles
Upcoming Intel CPUs have TME, current AMD processors have SME.
These are full-memory encryption techniques to protect against physical attacks such as cold boot attacks.
Both support encrypting the entire RAM from boot so that software d… Continue reading How does full memory encryption in newer processes protect against DMA attacks?
Typical USB tokens (Nitrokey, YubiKey…) allow an everyday user to store PGP keys and use them to encrypt email, harddrives and so on.
The same vendors also offer distinct products called HSMs (Nitrokey HSM, YubiHSM). The suggested use c… Continue reading Why is an HSM required to protect CA certificates (rather than a regular USB token)?
I’m trying to determine the feasibility of using a serial port/cable to act as a simple and cheap data diode. I’ll be connecting 2 Windows PCs (1 of which is on a secured network) using a 1-way null modem serial cable.
