NSTISSAM INFOSEC /1-99 July 1999
THE INSIDER THREAT
TO
U. S. GOVERNMENT
INFORMATION SYSTEMS
This NSTISSAM focuses on the insider and the potential damage that such an individual could
cause when targeting today's IS. It points out the various weaknesses (vulnerabilities) in
today's IS an insider might exploit and highlights approaches to solving these problems.
In taking corrective action, it is necessary to consider technical and procudural steps in
deterring the insider. Finally, we propose, in priority order, recommendations that
mitigate the threat posed by the insider. Our approach is not to provide an exhaustive
list, but rather offer recommendations that could have the greatest immediate return
against this serious threat
