An information security management system (ISMS) is focused on managing information security within an organization, a topic that is of growing concern to many organizations as they deal with the challenges presented in the information society including evolving information security and privacy legislation, published guidelines (OECD, cyber security), and threats natural (fire, flood, earthquake, tornados) or human introduced (viruses, spam, privacy, hacking, industrial espionage).
In an ISMS the information protected includes not just that residing in electronic format on computer or network, but includes paper-based information and extends as far as intellectual property. A properly implemented ISMS can be effectively used by either small or large organizations, and can be tailored to support the protection of information in diverse organizations including data processing centers, software development, e-commerce, health care organizations, finance, manufacturing, service organizations, non-governmental organizations, colleges, and not-for-profit organizations.
