  This paper will discuss the need for national-level organizational strategies
to effectively combat cyber security threats and cybercrime. In many countries,
new agencies have been established and/or new roles have been allotted to
existing agencies to cope with the needs for cyber security or fighting against
cybercrime. The two pillars of organizational structure and functions (i.e.,
security vs. law enforcement) have given new challenges to us, especially in
the context of traditional criminal justice system. To illustrate the
challenges, a case study examining the responses to major security incidents
followed by nationwide debates and remarkable organizational changes in Korea
will be given.
