CEOs blamed for computer attacks at workplaces

But the same rule doesnt apply to the senior leaders of a company.

8220;But woe betide the lowly IT director that would inconvenience the CEO with such restrictions,8221; New Scientist magazine quoted Glenn Zimmerman,a technology expert with the Pentagons cyberspace task force,as saying.

Warning a London conference on Cyber Warfare,he said that most senior leaders8221; computers are often wide open to threats,8221; and that it was often the CEO who held the most critical data.

Cyberwar analyst Yael Shahar of the International Institute for Counter-Terrorism in Herzliya,Israel,suggested that the best way to deal with this threat from within is to hack their computers and show them what you find.

8220;They may close the door and show you out,but their security awareness will have gone up a notch,8221; she said.

Zimmerman said that the solution would be to use less arduous security measures.

He pointed out that locking down PCs made tech-savvy users to find workarounds,which introduce vulnerabilities.

8220;The only totally secure computer is one that is switched off,filled with concrete and dropped to the bottom of the Mariana trench, he said.
