"Cisco's actions with Mr. Lynn and Black Hat were not based on the fact that a flaw was identified, rather that they chose to address the issue outside of established industry practices and procedures for responsible disclosure. It is Cisco's opinion that the method Mr. Lynn and Black Hat chose to disseminate this information was not in the best interest of protecting the Internet," the company said in its statement.
By pointing out the possibility of a worm attack on Cisco's routers, Lynn has performed a valuable service, said Black Hat attendee James Pearl, a consultant with Booz Allen Hamilton.
He did not have kind words for Cisco, and said the networking giant's attitude toward security might ultimately be bad for Cisco's business. "Security through obscurity doesn't work. You can stick your head in the sand but your butt's in the air," he said. "Do I really want to go with a company like Cisco that had to hide their problems?"
But Lynn's former employer, ISS, came out "the real loser in this," he said. "They've lost somebody really good, and everybody's saying, 'You didn't stand up for your guy.'"
