In response to the growing threat of unauthorized penetration of computer systems once thought secure, the Naval Criminal Investigative Service (NCIS) established the Computer Investigations and Operations Department (CIOD). The CIOD holds seminars and provides computer security training for military commands and military family groups on bases around the world. In addition, it publishes a series of brochures, each one tailored for a specific audience, including parents; an accompanying shareware program helps parents monitor their children's Internet activity. By all accounts, the program is achieving its goals. Employees are more aware of the types and effects of computer crime and are more likely to report suspicious activity. The company that designed the program has created a version for use in law enforcement agencies' crime prevention efforts, and the Maryland State Police has adopted a computer crime prevention program of its own, based on the one developed by the NCIS.
