A recent Avecto survey of more than 500 decision-making information security professionals, conducted last month at Infosecurity Europe in London, has found that 41 percent of respondent said rogue employees are the greatest threat to their organization (h/t Softpedia).

Still, more than 30 percent of respondents admitted that they have no policy in place for managing administrator access.

Another 31 percent of respondents said malware exploits and targeted cyber attacks are the greatest threat to their organization, and 8 percent said unauthorized software presents the greatest risk.

"In today's increasingly complex threat landscape, organizations are quickly learning that employees don't have to be malicious to put a company at risk," Mark Austin, co-founder and CEO of Avecto, said in a statement. "The most common threat comes from employees who download and install unauthorized software, without understanding the potential risks associated with their actions."

"Users logging on with full administrator rights will continue to put organizations at real risk of infection, as the sophistication of malware and targeted attacks continues to evolve," Austin added. "Unfortunately, organizations are still allowing administrator rights to go unmanaged, whether knowingly or unwittingly. This is a significant problem, particularly as the current crop of anti-malware software is repeatedly proving to be deficient in the fight against cybercrime."
