JAPAN introduces security measures that can be undertaken immediately. For details, please refer to “More security guides (Japanese only)".
Safety of data pathways
Yahoo! JAPAN encrypts the communication pathway between Yahoo! JAPAN and our customers using a robust structure in order to prevent third parties from stealing and altering Customer Data.
Safe storage of data
It goes without saying that Yahoo! JAPAN safely stores data, but when the management of data is outsourced to other companies, Yahoo! JAPAN conducts periodic tests on strict items to check if organizational/physical security measures, etc. are conducted in these companies.
Strict management of personal information
Access authorities to our Customer Data are restricted to minimum possible in our system. In addition, our Customer Data is stored in a heavily protected physical location, and there is a structure in place so that only limited persons can handle such data.
Framework to protect data
In order to promote the security measures mentioned above, we have appointed a Chief Information Security Officer (CISO) and persons responsible for information security for each organization. We make sure to thoroughly conduct organizational measures to protect our Customer Data in all scenes.
In addition, from fiscal 2017, we have appointed a Chief Data Officer (CDO) and persons responsible for data in each service in order to promote the use of data while observing laws and regulations and giving consideration to privacy. Data management is thoroughly enforced so that our customers can use our services safely and comfortably.
