## Highlights

The Los Alamos National Laboratory (LANL), which is operated by the National Nuclear Security Administration (NNSA), has experienced security lapses protecting information on its unclassified computer network. The unclassified network contains sensitive information. GAO (1) assessed the effectiveness of the security controls LANL has in place to protect information transmitted over its unclassified computer network, (2) assessed whether LANL had implemented an information security program for its unclassified network, and (3) examined expenditures to protect LANL's unclassified network from fiscal years 2001 through 2007. To carry out its work, GAO examined security policies and procedures and reviewed the laboratory's access controls for protecting information on the unclassified network.
