Directly under management and cross-functional organization within the company
The TDC-CSIRT is established as an organization that reports directly to management, allowing for prompt response, including managerial decision-making, in the event of a security incident. The TDC-CSIRT is composed of employees with specialized knowledge from various divisions within the company, and has a cross-functional support system.
Outline of Activities
TDC-CSIRT conducts the following activities in order to deal with security issues that are becoming highly complex.

Vulnerability Information Provision
We quickly catch information on various software vulnerabilities, etc., and consider measures to deal with them. In recent years, Heartbleed and other serious software vulnerabilities have been discovered, which have had a significant impact on the continuity of services around the world. In order to respond to such situations, TDC-CSIRT monitors software security information.
Security Incident Response
We take prompt and appropriate action in response to incidents such as information leaks. In the unlikely event of a service outage or information leakage in our services, we will quickly contain the incident, eradicate the cause, and restore services with the support of TDC-CSIRT.
