UTokyo Basic Policy for Information Security

1. Basic Policy for Information Security


To fulfill our mission to advance humankind by conducting research and educational activities appropriate for the highly information-orientated society of the 21st century, the University of Tokyo (UTokyo) must not only maintain our information infrastructure but also ensure the security of our information assets. The Policy for Information Security stipulates the arrangements necessary to ensure information security, and consists of Basic Guidelines and Standards for Countermeasures. Furthermore, specific procedures are defined in order to ensure reliable implementation of the Policy for Information Security. These measures are intended to raise awareness of the importance of information security among all users affiliated with UTokyo, and ensure the security of all information assets owned by the University.

2. Objectives of the Basic Policy for Information Security

The target users and target assets of the Basic Policy for Information Security are as follows:


Executives, full-time and part-time faculty and administrative members, students and research students (including those auditing classes), and persons with approval to access information assets owned by UTokyo (joint use users, visitors, outside contractors, etc.).


All information assets owned by UTokyo, including “information” and “information systems”. All media (magnetic, optical, paper, etc.) containing information are subject to this policy. This includes magnetic discs, flash drives, and handwritten notes. For the time being, test samples such as DNA samples are excluded. Information systems refer to any system that handles information. Examples include electronic systems as well as systems that handle printed materials, such as the internal mailing system. This policy is applicable to all university-owned information assets even if they are stored outside UTokyo.

UTokyo’s Policy for Information Security has four main objectives:

  1. Thorough categorization and corresponding management of information assets owned by UTokyo based on their level of importance.   
  2. Defense to prevent violations of information assets owned by UTokyo
  3. Prevention of damage to the information assets owned by UTokyo   
  4. Implementation of early detection and prompt handling of security breaches at UTokyo
