NTT-CERT provides security support for NTT Group companies

NTT-CERT, operated by the NTT Information Sharing Platform Laboratories, is an organization that works with security managers and systems administrators to handle security threats and provide technological support within the NTT Group.

In fiscal 2008, we adopted a diagnostic security risk management system that we had been developing since fiscal 2006. We have also been engaged in planning and implementing security training programs for employees, and enhancing cooperation between telecommunications equipment security engineers within the NTT Group.

Initiatives for protecting customers' personal information

Enhancing measures to stop information leaks and prevent reoccurrence

In fiscal 2008, several information leak incidents occurred, such as the external leakage of business-related files removed from company premises without authorization by a former employee (NTT East), and the use, perusal, and external leakage of customers' personal information by a retail agency staff member (NTT DOCOMO). Group companies take such incidents very seriously and have strengthened measures to prevent a reoccurrence, such as by redoubling their efforts to train employees in the proper handling of information, and introducing software to prevent the leak of confidential information.
