An audit of NSA's inspector general suggests that the agency's data retention policies raise issues for civil liberties. According to NextGov, the audit, which reviewed data deletion efforts, compliance efforts and retention controls, found the NSA's primary content repository has retained a small percentage of a large number of SIGINT data objects beyond legal and policy retention limits." Moreover, the audit refers to NSA's data retention guidance as "outdated" and oversight supporting retention compliance as "insufficient."
