A municipal computer engineer faces charges of hacking San Francisco’s computer network and creating a secret password which gave him exclusive access to most of the city's municipal data.

The hacker is currently in jail with a $5 million bail, but he still refuses to reveal the password that would give back San Francisco’s employees the access to the city’s computer system. The engineer – 43 –year-old Terry Childs – was scheduled to appear in court and he is expected to plead not guilty, his lawyer told ABCNews.com.

Childs was put under arrest Sunday and was charged with four counts of computer network tampering. His lawyer described Childs bail as crazy and suggested the charges resulted from a misunderstanding.

"He didn't kill anybody, and murderers usually get a $1 million bail, so you do the math," he said.

The internet system on which the employee of the city's Department of Technology worked reportedly stored 60 percent of all municipal data, including the city's 311 system, employee e-mail and law enforcement records. Childs worked as a network administrator for five years
and plaid a key role in the process of designing the router system for the city's Fiber wide-area network.

However, as San Francisco Mayor Gavin Newsom told reporters Tuesday, there is nothing “to be alarmed about.”

"Save the inability to get into the system and tweak the system. Nothing dramatic has changed in terms of our ability to govern the city," the Mayor added.

Adam Shostack, the author of the New School of Information Security said about the situation that it shows clearly how much power insiders really have. Nevertheless, as the city’s mayor has said, we need not worry because such cases are very rare.
