Quality software means more secure software.
I found a great article/interview on ComputerWorld with Gary McGraw, discussing hacker exploits and the state of software quality.
I just can't wait to get Gary's book. If his writing style is anything like his interview style, it should be really good.
Anyways, if you are into learning Gary's take on building more secure software by writing better quality software, consider reading the interview. [Dana Epp's ramblings at the Sanctuary]
