comment Why do coffee shops not use WPA/WPA2? Would it solve many problems if they did?
@user54791 WPA2-Enterprise does not imply "different username/password to each customer".

comment What things should I check for when giving a client control of the filename parameter to C's open() function?
Sidenote: sizeof(char) is 1 by definition.

comment If a phone is encrypted at a platform storage level do I need to encrypt my data stored on it?
@sisterray The problem with a browser is that it is almost always used; if you app is used for short period of times, it might make sense to protect its data with a specific password.

@ParthianShot Unless you don't have your browser opened all the time (which would be quite exceptional), and you don't use need your passwords all the time (the remember password feature is useful when you have many passwords and use these often), and your little brother could still get your passwords and use your online accounts. Conclusion: Lock your computer.

There is probably much more than MAC addresses in the log file.

"non-repudiation" of what exactly?

@Polynomial 1 is a most descriptive term than sizeof(char).

@Polynomial "that the size of the type is relevant" of which type? Why not sizeof (sometypedef)?

comment How vulnerable am I on a unencrypted public WiFi network?
WPA-Personal with a PSK shared with strangers is not very secure obviously; still, you at least get a session key, which allows encrypted unicast from/to AP. Of course, only symmetric encryption is used, based on a shared secret, so anyone could capture and decrypt the auth phase and recover the private session key. But 1) this requires some effort (more than trivial listening on open Wifi) 2) only those who captured the encrypted session key packets can do the decryption. So WPA-Personal provides some obfuscation. But you should move to Enterprise mode instead.

sizeof(char) is 1. Always. By design. By definition. Don't compute sizeof(char).

comment Can the USB standard be altered to prevent the “firmware attack”?
@nealmcb Probably, but you would first need to configure the networking device; maybe with the keyboard and pointing device included in the same USB chip?

comment Can the USB standard be altered to prevent the “firmware attack”?
USB isn't a standard about flash memory design, or mouse design, it's a networking standard. A networking standard, even PXE, has no business ruling on loader signature, kernel signature, etc.

comment Can the USB standard be altered to prevent the “firmware attack”?
I have no idea what you would like to standardise. I bet firmware, firmware loaders, and chips are not standard. A USB standard's aim is interoperability, not security. It's about standard protocols. If people want to play and reprogram USB devices, it isn't the task of a standard to rule on that.
