In this white paper, we highlight the ever-growing need for data protection security best practices for enterprise computers. Data protection security best practices include the encryption of data to prevent it from falling into the wrong hands, the preservation of data through backups, and the destruction of data when it is no longer required. The document discusses the data and information security issues associated with personal computers, explains the overall benefits and challenges of encryption as an effective mechanism in mitigating the increasing threat of lost business and personal data, and presents the overall benefits of Iron Mountain's DataDefense offering.
