The invention is a system to secure data. The data security system includes data, a data security system enforcer, a local policy database, and a centralized policy manager. When a block level file access request is received, the data security system enforcer checks the local policy database to see if the file access request is authorized. If the file access request is authorized, then the file access request is performed. Intrusions may be determined based on the type and number of unauthorized file access requests. Forensic analysis may be performed on a database logging file access requests (both authorized and unauthorized).
