A rule-based security system and method that uses an environmental access control software program (EAC) loaded into the working memory of an electronic device to prevent unauthorized usage of selected hardware components, the operating software program or data files stored on the electronic device. The EAC includes a filter driver, a rules database, an environmental detection engine, a rules application engine, key generator, and a rules menu interface generator. During setup, the rules menu interface generator creates a menu that allows the administrator to select one or more environmental rules that are linked or coupled to various environmental factors on or connected to the electronic device. Some or all of these factors are assigned to a key share value. When accessed to a protected resource is requested, the environmental rule for the resource is determined and the key shares values associated with the resources recite in the environmental rule are combined to create a master access key or a temporarily access key that is compared to a stored master access key so that access to the resource is provided.
