Information Security and Cyber Security
We recognize that it is our duty to protect the information assets entrusted to us by our customers and business partners as well as our own information assets in order to provide better products and services and contribute to the development of society. Based on this concept, NEC has positioned security, accurately referring to both information security and cyber security, as one of the critical subjects of “materiality,” its priority management theme from an ESG perspective—materiality, and has established its “Information Security Statement” as the basis for driving our efforts.
NEC has evaluated risks from various perspectives including the need of countermeasures as well as the possible damage both to corporate business and society, and has selected priority risks that will have huge impacts and that need to be addressed. With these risks in mind, we are deploying measures to counter cyber attacks that are becoming increasingly sophisticated, while complying with the U.S. National Institute of Standards and Technology (NIST) Cybersecurity Framework Version 1.1 and the Cybersecurity Management Guidelines Version 2.0 by Japan’s Ministry of Economy, Trade and Industry (METI).
In addition, almost 100% of our business divisions in which information security is particularly important, such as healthcare, finance, government, and cloud computing services, have obtained Information Security Management System (ISMS) certification.
Based on our information security implementation framework (see the figure below) as well as on our Purpose that shows why as a company we conduct business, NEC is working to realize a secure information society and provide value to our customers.
To protect information assets, NEC is taking the following approach:
- Implementing cyber attack measures
- Providing secure products, systems, and services
- Promoting information security in collaboration with business partners
At the same time, we have positioned information security management, information security infrastructure, and information security personnel as the three pillars of the information security governance framework within the NEC Group, thereby maintaining and improving our comprehensive and multilayered information security.
Information Security Implementation Framework
The NEC Group’s information security implementation framework comprises the Information Security Strategy Committee, its subordinate organizations, and the people in charge of information security management and promotion at each Group company. Under the direction of the Chief Information Security Officer (CISO), the NEC Group devises information security measures based on cybersecurity analysis, and NEC Group companies cooperate to promote these measures. In addition, we conduct annual penetration tests via a third-party organization in order to assess vulnerability risks. We also conduct regular audits of all Internet servers four times a year. These actions ensure that vulnerabilities are dealt with in a timely manner. The corporate executive who assists the CISO oversees the office of the CISO, which promotes information security measures, and the PSIRT, which monitors for cyberattacks and resolves incidents quickly whenever they occur.
In light of recent geopolitical conditions, we have established the Economic Security Management Office. The office investigates and analyzes across the NEC Group cybersecurity, export restrictions, and other risks from an economic perspective, formulates strategies, and addresses these risks.

Measures and Main Fiscal 2022 Activities
Information Security Management
To facilitate the establishment of a variety of Group-wide measures, we have introduced an information security management system and security policy, both of which we make every effort to maintain and improve.
Information Security Risk Assessment
The NEC Group conducts risk assessments and implements countermeasures by analyzing deviations from baseline criteria and carrying out detailed risk analysis, with both methods conducted in a proper manner. First, we ensure that security is implemented in line with criteria that serve as a baseline, and when more advanced management is necessary, we conduct a detailed risk analysis based on the Information Security Risk Assessment Criteria and implement finely tuned countermeasures.
Risk Management for Information Security Incidents
Information security incidents are subject to mandatory reporting. The contents of these reports are analyzed and the results are put through a PDCA cycle for risk management assessment. Incident information is centrally managed for the entire NEC Group, and changes in the number of incidents, trends by organization and type of incident, and other data are analyzed. From there, NEC reflects this analysis in Group-wide measures while also measuring the impact of these incidents.
Measures against Cyber Attacksd
As cyber attacks grow increasingly complex and sophisticated, the NEC Group focuses on the protection of information assets entrusted by customers and business partners as well as its own. To this end, we have implemented total cyber security management by conducting uniform and advanced measures worldwide based on cyber security analysis, and established an incident response framework with our Computer Security Incident Response Team (CSIRT).
In particular, given that NEC creates and provides social solutions for countries worldwide, a single information security incident caused by a cyber attack or any other factor could diminish the social trust of the entire NEC Group and materially affect its business management. For this reason, we view a comprehensive and global approach to cyber security risks as essential for our business continuity.
We are strengthening our global measures against increasingly sophisticated cyber attacks based on a multilayered defense approach. In fiscal 2021, our measures focused on the following tasks.
|Cyber risk assessments by “Red Team”
|Generating and utilizing threat intelligence
|Enhancing organizational security resilience
|Critical information management
Providing Secure Products, Systems, and Services
NEC has established a security implementation organization structure to facilitate secure development and operations of the products, systems, and services it provides to customers. This structure comprises information security managers assigned to each business unit and follows the concept of security by design (SBD) to ensure security comprehensively from the planning phase through to the operation phase.
Information Security in Collaboration with Business Partners
NEC conducts its business activities in collaboration with business partners. In these collaborations, we believe it is important to ensure that the technology capabilities and information security level of the business partners meet our required standards. To this end, NEC categorizes its business partners by information security level based on the implementation status of their information security measures. In selecting business partners for a project appropriately, we check the information security level to outsource tasks, thus reducing risks of information security incidents occurring at business partners. In addition to the measures stated above, we conduct document security survey checks and on-site inspections for business partners. Every year we review inspection items in light of any incident trends or in consideration of the business partner, issue a report of the inspection results and provide the business partner with feedback, and follow up on any issues that require improvement.
