We strengthen CSIRT operations to reduce the security risks of Companywide IT systems.

Advances in an ICT-based society have raised the threat against cyber security for both individuals and corporations. We are therefore bolstering our countermeasures toward realizing a safe and sustainable social infrastructure.

Building a CSIRT Operation System for a Quick Response to Incidents

Ensuring information security is the core of our initiatives as an ICT company, and we have repeatedly sought to bolster our countermeasures for the Companywide IT system to address threats against cyber security that continue to grow in sophistication and diversity. The relationship between cyberattacks and security measures is often a vicious cycle, which means that eliminating the threat completely is impossible, no matter how many measures are implemented. We launched an internal Computer Security Incident Response Team (CSIRT) in July 2017 with an emphasis on minimizing the impact and limiting damages in the event of an incident.

Building a CSIRT Operation System for a Quick Response to Incidents

Building a Robust Social Infrastructure by Creating a Self-Detection Mechanism against Cyberattacks

It is often the case that people only realize they are under cyberattack after being warned by someone else, and thus fall one step behind in their response. We therefore believe it is important to create a corporate self-detection mechanism against cyberattacks. For example, an event in the security equipment will trigger a review of server logs and network equipment,visualizing and analyzing them from a security perspective,which in turn leads to early detection and response to a threat. The pressing issue in the years ahead will be to organize incident response operations into standardized management operations and establish a management system with the optimal number of staff. Also, we will actively develop security experts by utilizing CSIRT operations as a field in which we practice and experience operations for security management.
