Book excerpt: The federal computer fraud and abuse statute, 18 U.S.C. 1030, outlaws conduct that victimizes computer systems. It is a cyber security law which protects federal computers, bank computers, and computers connected to the Internet. It shields them from trespassing, threats, damage, espionage, and from being corruptly used as instruments of fraud. It is not a comprehensive provision, but instead it fills cracks and gaps in the protection afforded by other federal criminal laws. This report provides a brief sketch of Section 1030 and some of its federal statutory companions, including the amendments found in the Identity Theft Enforcement and Restitution Act, P.L. 110-326. Extensive appendices. This is a print on demand publication.
