IT staff may be a primary source of data leakage, according a survey of 300 IT professionals at the recent Infosecurity exhibition in London.
One-third of those questioned said they used their administrator passwords and privileges to look at confidential company information. This included salary details, merger and acquisition plans, personal e-mails, board meeting minutes and other pieces of personal information. Some 47% said that they had accessed information that was not relevant to their role.
The survey is part of ongoing research by IT security firm Cyber-Ark into industries' information access and control procedures.
Researchers reported that privileged passwords are changed less often than user passwords. They found 30% change once a quarter and 9% never get changed.
Half of IT administrators do not need authorisation to access privileged accounts. This shows a general lack of control of these power identities and indeed understanding over the power that these privileges command, said Mark Fullbrook, UK director of Cyber-Ark.
Data exchanges were also vulnerable. One in three e-mail sensitive data, 35% send it via courier, 22% use FTP and 4% still use the postal system. And 12% of these senior IT staff also chose to send cash in the post.
