The SoftBank Group's information security initiatives are based on the SoftBank Group Guideline for Information Security Measures. Examples of measures adopted by major Group companies are as follows.

SoftBank Mobile recognizes its legal and social responsibilities as a provider of mobile phone services, and has been implementing information security measures that give the highest priority to safekeeping customers' personal information and protecting the confidentiality of telecommunications.
Its Privacy Policy contains guidelines on personal information that have been established to promote a strong awareness of information security among all officers and employees. This policy is supported by a range of ongoing educational activities, including distribution of a Personal Information Protection Handbook, regular training sessions, and other measures such as e-learning focusing mainly on personal information protection and privacy of communications.
SoftBank Mobile has completely separate physical locations and network access for individuals and groups according to each security level, and every effort is made to enhance information security by sharing relevant knowledge and technology between SoftBank BB and SoftBank Telecom.
In addition, as part of its efforts to ensure information security, SoftBank Mobile has been running operations at all of its directly managed SoftBank shops* in a manner compliant with ISO27001, an international standard for information security management system. Regular security inspections are also carried out at sales agents and shops, providing necessary instruction and education so that companies who provide outsourced operations can maintain the same securities standards.

SoftBank BB is a provider of comprehensive broadband services through Yahoo! BB, which operates Japan's largest number of lines, and as such takes a comprehensive approach to information security. SoftBank BB has established an Information Security Policy applicable to all employees throughout the organization. This policy includes having a designated post with responsibility for information security management, and running an Information Security Committee. SoftBank BB also appoints an information security manager in each department to help ensure a robust system.
A Security Operation Center (SOC) has been established to address both technology and operations, and dedicated staff members are on duty around the clock, 365 days of the year to monitor internal security and carry out internal audits. The SOC undertakes detailed monitoring of office computers, internal networks and server access, and rule violations are dealt with promptly and strictly.

In the actual operating environment, security has been divided into five levels, and access to respective locations is managed accordingly for each level. Anything Level 3 or above is categorized as a “high security area,” and personal information is handled only in these areas. For example, a customer support center designated Level 3 has rigorous security, with security guards, access card identification, designated uniforms, the use of transparent bags for personal belongings in order to prevent the carrying of prohibited items, and careful layout of work stations and monitors to ensure the transparency of work processes.
At the same time, SoftBank BB provides officers and employees with education on personal information protection, including training sessions and e-learning. Further information on information security is posted on the intranet for employees to browse through at any time.
The Information Systems departments of SoftBank BB, SoftBank Telecom and SoftBank Mobile have each received ISO27001 certification — an international standard for information security management systems — for the operation of their internal systems, systems monitoring, and security monitoring.

SoftBank Telecom recognizes its legal and social responsibilities as a provider of fixed-line telecommunication services, and has implemented strict measures to maintain confidentiality of telecommunications and protect personal information.
SoftBank Telecom operates an Information Security Committee, chaired by the information security officer, which conducts comprehensive risk assessment of owned information assets, and is responsible for the establishment of the Company's Information Security Policy.
Regular educational activities are provided for officers and employees. These are mainly focused on providing participants with the knowledge and tools required to enable rigorous protection of communication privacy and personal information in their day-to-day work activities.
Further enhancement of information security is addressed by controlling physical and network access by individuals and groups according to their respective security levels. For employees who telework from outside Company premises, communication security measures include individual authentication and data encryption when accessing internal networks via the Internet, and IC card authentication and file encryption to prevent information leakage even if an employee's laptop computer is lost or otherwise compromised.
Moreover, as part of its efforts to ensure information security for its customers, many divisions of SoftBank Telecom have obtained ISO27001 certification, an international standard for information security management system.
