~2½ page information security policy template on clearing unattended desks and screens.
The policy provides pragmatic guidance on protecting information in conventional and unconventional workplaces (e.g. on public transport) against inappropriate disclosure and other threats.
Keeping workplaces clean and tidy is more than just a matter of looking smart. Protecting information in corporate and home offices, mobile workplaces etc. is largely a matter of common sense. Habitually clearing desks of information and screen-locking computers before walking away helps secure information at negligible cost.
Coupled with additional controls such as oversight and awareness, physical security/access controls and assurance measures such as internal reviews and site penetration tests, this simple policy becomes even more cost-effective. It's a winner.
