Comment: Security Trying To Hold Back Progress, Again (Score 1) 60

So here we have security vendors trying YET AGAIN to hold back progress in Internet protocols. They did it with window scaling, ECN and IPv6. Each new invention doesn't work with their snake oil so they either disable it or tell people not to use it.

They like to lock down HTTP too, preventing anything that doesn't "look right." As if a server would respond to PUT or OPTION if it didn't intend to support that.

Software that monitors the traffic for unusual patterns or attack patterns is not a firewall. It is an IDS (or IPS depending on configuration) such as Snort.

Consumer desktop PCs have "antivirus" software which is a combination of firewall, IDS, antivirus and other malware detection systems. Enterprise network admins have firewall, IDS, NAT, and many other systems with each one configured separately.

Network admins have many words for things like Eskimos do for snow because precision is important.

But how do you know which parts are relevant to you?

I mean, you might think a little thing like the Constitution is perfectly clear when it lays out the rules for regulating interstate commerce. I bet you didn't know that growing wheat on your own small farm and eating it yourself is interstate commerce.

I was wrong about XP needing to map all 3 GB of video RAM.

It is more accurate to say that Windows XP limits the GPU to a 256 MB window. The GPU would perform a lot better if all of its memory was mapped for direct access.

The newer pieces of GPU hardware and drivers are using zero-copy direct memory access with addressing that is the same on the GPU and the CPU which allows sharing of data structures without copies or modifications. That can't be done in a 256 MB window, or if it can, not well.

How do you expect the keyboard is attached? USB. I've actually seen this, in person. A machine with sealed USB ports ... and a USB keyboard and mouse. Really. What was IT thinking?

I bet the IT guy who did the job was a contractor. 'Uh yeah, here's a work order to seal up all the open USB ports.' "What about the keyboard?" "Doesn't say. Don't ask questions: its 20 hours of easy work at $60/hr."

No the problem is in the hardware.

If there are super specific timing requirements then invent a new standard with the commands you need. Then put a little microprocessor on the serial port end in charge of waiting for some particular signal and responding in precisely 23 milliseconds. Or whatever.

Well, if I was really into industrial espionage I might do something like bring a USB stick loaded with my zipper program, but instead of storage set to look like a keyboard. Plug it in, open Notepad and have it type the executable out into a file.

I've noticed that a lot of places disable USB storage but don't disable file execution from writable directories.

Sounds like the real answer to this problem is an improved USB to serial dongle. If this is a serious problem for electronics engineers, they are the perfect people to fix it. Whatever the problem with the USB to serial interface is, fix it. Then sell your improved serial port adapter for $100. Profit!
