Web site security aims to balance allowing access while keeping strangers out. There is little difference between physical and digital security. Security requirements depend on the site's purpose and sensitivity of data. To determine basic requirements, an organization should consider what needs protection, educating users, backup plans, and monitoring maintenance.
