A security culture is a set of customs shared by a community whose members may engage in illegal or sensitive activities, the practice of which minimizes the risks of such activities being subverted, or targeted for sabotage. The term is used in the context of activist groups and movements, particularly ones that might be involved in direct action, but it is also in use in most corporations, and certain arms of government. The main focus of a security culture is keeping infiltrators and other potentially damaging parties out.[1]
