Nova Scotia's new auditor general says he's concerned the province has left security gaps in some of its computer systems.

In his first report since starting the job in March, Jacques Lapointe said a computer system in the Department of Community Services has left a door open for mistakes or abuse.

Lapointe listed a number of problems, including too many people with one password. He noted some of these people had moved on to other jobs and shouldn't be authorized to use certain computer files.

A big concern for the auditor general was that most of the computer security issues had been raised in the past by previous auditors general.

"The speed of reaction to these has not been great, and I'm concerned that similar issues keep getting brought up," Lapointe said.

He didn't cite any specific examples of mistakes or wrongdoing that resulted from the problems, but said the systems expose government to great risks.

Lapointe said a lack of information about spending estimates for 2006-07 made a full evaluation impossible.

The auditor general found other problems that were not related to computer security, such as health authorities that are forced to make business decisions about how to run hospitals before budgets are approved.

He also said school boards are open to risk because there are few controls over the millions of dollars they fundraise.
