San Francisco Case Shows Vulnerability Of Data Networks

San Francisco is being forced to overhaul security measures on the computer network that controls data for its police, courts, jails, payroll and health services, as well as other crucial information, after the technology administrator entrusted with the system blocked access for everyone but himself last month and for days refused to reveal the password, even from jail. The ordeal has spurred the city's IT department to bolster network oversight and to consider hiring outside auditors to monitor a security upgrade. City officials also will review all access to its FiberWAN network, the hub through which payroll, e-mail and criminal files flow. It has also persuaded other cities to scrutinize their own systems.
