8-character passwords are so 1999 – 12 characters is 21st century

Today’s computers and add-on processors (think graphics processing units – GPU‘s) are extremely powerful. The GPU of today offers about 2 teraflops (10^12 floating operations/sec) of parallel processing power. In 2000, a supercomputer yielded computing performance of just over 7 teraflops and costs $110 million.  This computing power has increased the automated password cracking (brute force attacks) threat. In a recent research project reported by the BBC, computer scientists at Georgia Tech Research Institute say that passwords of less than 7 characters with special characters will soon be “hopelessly inadequate”. They recommend passwords of 12 characters or more.

Well, time to pull out my PasswordCard and begin using my 29-character password. What other suggestions do you have for other ITKE readers? Thanks for reading and let’s continue to be good network citizens!
