As the types of equipment within a company diversify, especially teleworking and self-contained devices (BYOD), effective management and control of network access has become a major challenge for enterprise safety management. The Network Access Control System (NAC) as an effective security protection technology can fundamentally improve cybersecurity and ensure that business networks are open only to authorized users and equipment.
Core functions of the Network Access Control System (NAC)
The network access control system provides a full range of security protection for the enterprise network by controlling and managing equipment, users and their behaviour that connects to the enterprise network. The core functions of NAC systems include identification and equipment certification, access control, real-time monitoring and unusual detection.
Identification and equipment certification
One of the basic functions of the network access control system is identification and equipment certification. Identification ensures that only authorized users have access to the enterprise network, while equipment authentication ensures that equipment connected to the network meets business security standards.
Identification is usually verified by various means, such as username/passwords, dual factor authentication, digital certification. The authentication of equipment is validated by checking the security status of the device (e.g., operating system version, patch update, etc.). Whether office equipment, smartphones, and networked printers and sensors require all equipment to be certified to access the business network. This certification process effectively avoids intrusion into unauthorized equipment and malicious software, providing a reliable safety line for businesses.
2. Dynamic access control and fine particle size rights management
The network environment of enterprises is becoming more complex, and the demands on network resources vary greatly among different staff, equipment and systems. Network access control systems can assign different access rights to different users and devices depending on their identity and type of equipment.
For example, the financial services of an enterprise may need to access sensitive financial data, while the general staff do not need such privileges. Through dynamic access controls, NAC systems can adapt access rights flexibly to factors such as role, sector, equipment health.
3. Real-time surveillance and detection of abnormal behaviour
The network access control system not only functions in terms of access controls, but also allows for real-time monitoring and analysis of equipment and user behaviour on the network. Once an anomaly or a potential security threat is detected, the system alerts and responds to it.
Through behavioural analysis and data flow monitoring, the NAC system can identify unusual access patterns, such as attempts to bypass access controls, unauthorized access to equipment, and data transmission anomalies. When an anomaly is detected, the system can respond immediately to a pre-defined security strategy, such as forcing network disconnections, limiting access rights or triggering security incident alerts. This real-time surveillance and abnormal behaviour detection not only helps businesses detect potential threats in time, but also reduces damage caused by security incidents at an early stage of the event.
4. Centralized management and automated response
With the expansion of the enterprise, the number of equipment and systems in the network has increased dramatically. Traditional manual management is no longer able to cope with an increasingly complex network environment.
The system not only warns security threats when they are detected, but also automatically enforces protection measures. For example, the system can automatically restrict or interrupt access to substandard equipment based on a predefined security strategy, or compel users to certify it twice.
5. Support for multiple modes of access: secure remote office and BYOD
As the trend towards teleworking and by-product (by-boarding) has emerged, business networks have become more diverse in terms of access. Employees may need to access corporate resources through personal devices wherever they are.
NATSHEL_BRAND’s network access control system can effectively address this problem. Whether it is accessed through VPN, Wi-Fi, and 4G/5G, the system can perform rigorous identification and equipment checks to ensure that only security compliant equipment has access to the enterprise network. Furthermore, NAC supports dynamic network access strategies that automatically adjust its access rights to secure remote office when equipment status changes are detected.
