Cyber Security
As industry becomes increasingly IT-driven and companies expand their operations via the Internet, measures against information leaks, cyber attacks and other security incidents have become a pressing issue for all companies. Cyber security requires that measures be taken to prevent issues from arising in the normal course of operations and to mitigate risks by taking prompt remedial measures if an issue arises. We provide comprehensive assistance in the development of cyber security systems during normal operations, including the establishment of internal governance systems and regulations, and vendor management. We also have extensive experience in crisis management in the event of a security incident. In collaboration with IT system experts, we also provide one-stop support for the entire process, from the initial response, including fact-finding and evidence preservation, to dealing with the authorities, information disclosure and the mass media, handling victims, root cause analysis, and recurrence prevention measures.
