Our employees must comply with the ISMS General Policy, and maintain and improve on ISMS.

Assets defined here include technology and know-how considered to be information used as managerial resources (documents, data, etc.), information systems, services, and facilities and equipment related to the protection and use of such assets.
- In implementing ISMS, we will construct ISMS suitable for our firm, and accumulate knowledge of ISMS development technology and operational management.
- Due to our firm personnel having a high degree of specialized knowledge, it is vital that operational know-how is accumulated, maintained, and passed on for business continuity. As such, work evidence (documentation, records) is saved through our ISMS for this purpose.
- To establish risk assessment criteria and to define risk assessment approaches based on such criteria. In order to perform each of our firm’s services, it is important to maintain confidentiality, integrity, and availability of our client’s and our firm’s assets. As such, risk assessment is conducted on the confidentiality, integrity, and availability of assets, resulting in proper identification of asset threats and vulnerabilities and of necessary security requirements.

- To comply with tax laws and regulations, Act on the Securitization of Assets, Financial Instruments Exchange Law, Certified Public Accountants Law, Certified Public Tax Accountants Law, Copyright Law, Act on Prohibition of Unauthorized Computer Access, Unfair Competition Prevention Act, and Act on the Protection of Personal Information, as well as ISMS related rules and standards.
- To conduct periodic education and training regarding information security to heighten employee awareness.
- To improve ISMS by measuring and evaluating the effectiveness of control measures through daily monitoring, monthly security checks and internal audit.
3. Operational Structure and Duty
Our management committee discusses and assesses the security standards and requirements and the countermeasures to ensure them based on our ISMS General Policy.
