As the risks of corporate information security increase, protecting networks from unauthorized equipment and user access has become a priority for many businesses. In particular, traditional cybersecurity protections seem to be inopportunity under emerging working patterns such as remote staff work, use of self-contained devices (BYOD) and hosting of enterprise data on cloud platforms.

Cybersecurity challenges facing enterprises
In the process of digital transformation, enterprises often encounter the following cybersecurity problems:
-
Uncontrolled access
In recent years, with the spread of the BYOD (self-contained equipment) policy, more and more employees have connected personal devices (such as smartphones, laptops, tablets, etc.) to the company’s network. The security of these devices is so diverse that they can easily become a weak link in cyberattacks without effective management and control. Unauthorized access to the enterprise’s network may not only create security loopholes but also lead to the dissemination of malicious software, posing serious security threats to the business.
-
Complex and variable network environments
The enterprise’s network environment is becoming more complex, involving a variety of equipment, users, systems and services. Employees use different devices and identification login, access varies (e.g. Wi-Fi, VPN, mobile data, etc.) and the need for different staff to access different resources.
-
Protection against internal threats
While enterprises have done a great deal to strengthen their external offensive defences, they often ignore the management of internal security. Many companies’ traditional security structures do not take into account the dynamic changes in staff behaviour, equipment health and access rights, leading to a significant reduction in network security.
Network access control system: a comprehensive solution for enterprise security management
The Network Access Control System (NAC) can effectively enhance enterprise security by providing strict certification and management of equipment and users connected to the enterprise network. Specifically, NAC provides businesses with several key functions that help them achieve full cybersecurity protection.
1. Comprehensive equipment certification: eliminating illegal equipment access
The primary function of NAC is to certify equipment and ensure that only the equipment meets safety requirements can access the enterprise network. The authentication of equipment determines whether it is safe by checking its health status (e.g., whether the operating system is up to date, if there are security gaps). If the equipment does not meet the requirements, the system will deny access to the network. For self-contained devices (BYOD), the NAC system will compel staff to verify their identity through pre-installed secure clients, ensuring that they have been cleared prior to network access.
This measure not only effectively prevents access to malicious equipment, but also allows for the fine-tuning of different types of equipment within an enterprise and avoids cyber security loopholes.
Flexible access controls: adjusted competencies to the dynamic of identity and equipment
The users and equipment in the enterprise network have different access needs to resources, and how can they ensure that access rights for staff members of different roles and different devices are consistent with the enterprise’s security strategy? NAC systems are dynamically adjusting user access through a refined identification and role management mechanism. Through role-based access control (RBAC), NAC can allocate different access rights to employees in different jobs and sectors, ensuring that each employee has only access to resources relevant to his or her work.
NAC also supports dynamic adjustments in equipment health and geographical location. For example, when an employee uses a device that is not healthy, the system automatically reduces access to its resources or prevents it from accessing sensitive resources altogether.
3. Real-time surveillance and detection of abnormal behaviour: timely identification of security threats
NAC systems are not limited to access equipment and user controls, but also have real-time monitoring and abnormal behaviour detection functions.
For example, the system can identify requests for visits from employees during off-time periods or from unusual geographical locations and trigger alarms or further verification through predefined security strategies. The system can also automatically take measures such as restricted access, isolation devices, or notification to managers of further processing of suspicious activities.
4. Support for multiple modes of access: safeguarding the flexibility and security of enterprises
With the emergence of new modes of work such as cloud computing, mobile officeing and so on, businesses have diversified their access patterns. The NAC system can support a variety of ways to access, including VPN, Wi-Fi, 4G/5G, etc., which ensures secure access to the company network regardless of where the staff is located.
NATHELL_BRAND’s network access control system provides staff with a safe and easy access experience through smart analysis and dynamic adaptation of their web strategy. For example, when an employee is on mission, if he or she needs to visit the company’s internal resources, the system adjusts access rights to his or her equipment status and network environment to ensure that the worker can perform his or her work efficiently while ensuring security.
