Wireless security puts IRS data at risk

Internal Revenue Service offices across the nation that use wireless technology are still vulnerable to hackers, according to the latest assessment of the agency's security policies released Tuesday.

Despite efforts to improve wireless security the past four years, the Inspector General's assessment of 20 buildings in 10 cities discovered four separate locations at which hackers could have easily gained access to IRS computers using wireless technology.

There was no evidence that the computers were connected to the IRS network at the time and no signs that any hacking had occurred, the report said.
