Today's enterprise is under siege from a barrage of regulatory requirements an ever-increasing threats to data security. Regulatory acts such as Sarbanes-Oxley, Gramm-Leach Bliley, Health Insurance Portability and Accountability ACT (HIPAA), Basel II and others are putting tremendous pressures on corporations not only to safeguard their sensitive data but to affirmatively prove their compliance with relevant regulations. Further, the costs of compliance are spiraling out of control. In 1999, U.S. companies spent $750 billion to comply with federal regulations. In 2005, according to Forrester Research, large corporations spent in excess of in excess of $10 million each on compliance with section 404 Sarbanes-Oxley alone.
