Threats to the security of social infrastructure systems are on the rise against a background of increasingly sophisticated cyber-attacks and a changing security environment inside and outside of Japan. Social infrastructure, meanwhile, plays a fundamental role in the functioning of society and is called on to maintain service continuity while dealing with a variety of incidents. In response to these challenges, Hitachi supplies security solutions for social infrastructure based on its concept of protection at the system, organization, and operational levels. It intends to continue contributing to the creation of a safe and secure society by supplying total services extending from consulting to products, system configuration, and security operations.
