What is DEP?
- No related posts
http://live.pirillo.com/ – One of our Romanian viewers wanted to know how to turn off Data Execution Prevention. Every time he thumbnails a video from his camera, he gets an error.
What is DEP? Data Execution Prevention is a security technology – based in software or hardware – that keeps programs from accessing or overwriting parts of memory that it doesn't already have access to.
Keeping DEP turned on is a good idea, but if it's giving you a problem, you can turn it off:
- Right click on "My Computer" and select Settings.
- Click on the Advanced Tab
- Click the settings button, under performance.
- Select the third tab.
- Within this tab you can turn it on for all programs, only windows services, or for all programs except programs you select.
Do you have any experience with DEP?

Gee, I always thought it was supposed to prevent executable code input as data from executing.
Did I get that wrong?

I believe Chris has memory protection confused with data execution prevention. DEP does indeed prevent a region of memory that contains data from being executed. This usually comes from input, but that is not necessarily the case.
