About Clay

I'm a Data Center Operations Engineer in beautiful Charleston, SC. I'm happily married to my wonderful wife Nan and we have an teenage daughter Lela. I'm a total geek. I got into electronics when I was around 9 or 10 and got hooked on computers shortly thereafter. I also love Sci-Fi, (not fantasy) particularly Star Trek. My favorite outdoor activities include rollerblading, biking and hiking. I'm also a bit of a car guy and amateur racing driver.

x86, vulnerable by design

The quest for ring 0

All x86 CPUs in modern systems (Intel, AMD, etc.) have a feature that could be exploited on some operating systems to take total control of that system. Interestingly, modern versions of Windows actually aren’t vulnerable to this type of attack because of their implementation of a hardware abstraction layer or HAL. There are also ways to harden other OSs against this sort of attack, but it’s more a matter of mitigation than prevention.

Media finally picks up on spy case

CNN.com – Telecoms named in NSA story say they guard privacy – May 12, 2006

After it’s attempts to kill the lawsuit against AT&T, the Bush administration now has to deal with a full assault from the mainstream media. Now that the bright light of public scrutiny has been fixed again on the administration, they’re all scrambling to deny any wrongdoing. I’m interested to see where this is going, but I’m not going to hold my breath on any meaningful consequences.
