The security threat posed by former employees is becoming a major concern for users tasked with keeping data assets secure.
Ever since the recession started to bite and the number of lay-offs began to snowball there have been growing suspicions that staff given the boot would take out their frustration on their employer by undermining data security.
Those fears continue to dominate the minds of IT managers looking after security according to the Ernst &Young Global Information Security Survey.
Richard Brown, partner in IT risk advisory at Ernst & Young, said that staff that had been laid off might feel resentful and there were a number of ways they could impact the smooth running of the operations.
"Increasingly, the IT system has become a common target and data theft is also prevalent. It is paramount that companies undertake a specific risk assessment exercise to identify their potential exposure," he said.
Other highlights in the survey included IT directors reporting continued strain on budget with security not immune from cuts along with the pressure to meet compliance demands.
"Government and industry-led regulations have clearly resulted in organisations adopting a more-structured approach to information security," said Brown.
The channel has consistently warned customers about the need to increase and improve internal security in the face of potential problems from former staff.
