In addition, the Cyber Force Center is established within the NPA as a technical core for measures against cyber terrorism. In order to promptly recognize occurrence of DOS $ ^{1} $ attacks or the situation of the computers infected with computer virus, it operates a real-time detection network system $ ^{2} $ running on a 24 hour basis. Moreover, this center functions as a technical support base for emergency correspondence when cyber terrorists occur, and assumes responsibility for providing assistance to Prefectural Police through Cyber Forces established in regional bureaus of each Prefectural Police.

A cross-divisional Anti-Cyber Terrorism Project is also established in Prefectural Police offices. It promotes various measures through cooperation between the public and private sectors by receiving technical support of Cyber Forces.

## (2) Approaches Related to Measures against Cyber Terrorism

## 1 ) Strengthening the Cooperation with Essential Infrastructure Providers

The Anti-Cyber Terrorism Project makes individual visits to each essential infrastructure provider in order to ask cooperation for investigation. At the same time, it organizes seminars on cyber terrorism countermeasures and Cyber Terrorism Countermeasure Councils to provide information and exchange opinions on information security. Besides this, joint training simulating such incidences is conducted with essential infrastructure providers, and thus striving to strengthen cooperation between private and public sectors.

## 2 ) Provision of Information to Internet Users

The NPA has started a security portal site “@police” (http://www.cyberpolice.go.jp/). The site discloses the latest information regarding new computer viruses and the vulnerability of various programs; in addition, the “Internet periodic observation” discloses data surrounding the state of cyber attack occurrence, which is automatically collected and analyzed in regular time intervals.

Note 1: Abbreviation of Denial of Service. A cyber attack in which a massive amount of repeated access to a certain computer makes the provision of services to the computer impossible.

2: A system to summarize and analyze information from sensors which are established in Internet connection points by police.
