The U.S. Postal Service relies on a complex computer infrastructure to support and protect their critical assets and has initiated information technology projects to enhance efficiency and increase revenue. The OIG’s work in this area assists the Postal Service in maintaining and improving computer security to reduce the risk of fraud, inappropriate disclosure of sensitive data, unauthorized disclosure of customer information, and disruption of critical operations and services. The Information Technology Directorate assesses whether Postal Service information resources provide the highest level of security, reliability, and value expected by Postal Service customers. To that end, the directorate plans and directs audits and reviews of major Postal Service information systems to determine whether management has established appropriate general and application controls, designed systems to be secure, and ensured the confidentiality and availability of data to authorized users.
