As the digital transformation of enterprises progresses, the IT environment becomes more complex. The various equipment (BYOD), the spread of teleworking, and the widespread use of cloud services are among the factors that workers bring to bear, pose unprecedented challenges to the security management of their networks.
The network access control system (NAC) is a response to these problems. It effectively prevents cyber security gaps by means of identification, health checks, and allocation of privileges for equipment and users connected to the network. This paper will examine the problems that enterprises often encounter in cybersecurity management and analyse how the network access control system can provide solutions for businesses.
Common pains in corporate network security
-
Lack of effective management of diverse access equipment
As remote office access and self-contained equipment (BYOD) increases, employees use different types of equipment (such as personal computers, smart phones, tablets, etc.) to access the enterprise network. These devices may have a variety of security risks, such as not having up-to-date safety patches installed, using unsafe operating system versions, malicious software, etc. Without effective management mechanisms, businesses’ networks may be exposed to attack or data leak.
-
Lack of flexible access control mechanisms
The network has a wide variety of users and equipment, and each user has different access needs to its resources. Traditional access control methods (such as simple user names and password authentication) are no longer able to meet the need for fine-scale access.
-
Failure to respond in a timely manner to internal and external security threats
Even with traditional security measures such as firewalls and IDS, cyber-security incidents continue to rise. Enterprises often lack real-time monitoring and automatic response mechanisms that may prevent them from detecting and responding quickly in the event of a safety incident, leading to an spread of potential security threats, loss of data or disruption of operations.
Network access control system: core solutions for enterprise security management
The network access control system (NAC) effectively avoids the above-mentioned problems by means of comprehensive identification, equipment health checks, and behavioral monitoring of equipment and users connected to the network.
Equipment and identification: eliminating unauthorized access
The equipment is strictly certified by the enterprise through network access control systems. Whenever an employee or third-party device attempts to connect to the enterprise network, the NAC system first performs a equipment certification to ensure that the equipment meets safety requirements (e.g. whether the operating system is updated, if there are security gaps).
At the same time, NAC systems also provide identification to ensure that users are legal in accessing them. For example, authentication of user identities is done by means of user names and passwords, dual-factor authentication, etc. Such dual certification can significantly reduce the risk of abuse of authority by internal agents and external hackers forging identity.
2. Flexible dynamic access control: fine-tuning of competency management
The NAC system provides flexible access rights based on the position, department, mission, etc. of employees. For example, finance staff can access sensitive financial data, while ordinary workers cannot.
In addition, NAC supports dynamic access controls that can be adjusted in real time to the security state of the equipment, geographical location of staff, and time periods. For example, when an employee uses personal devices to visit a network on mission, the system automatically adds secondary authentication to ensure the safety of its access behaviour.
3. Real-time surveillance and detection of abnormal behaviour: responding to potential threats in a timely manner
The network access control system has a powerful real-time monitoring function that allows continuous monitoring of equipment and user access.
The smartness of NAC systems not only recognizes traditional external attacks, but also detects unusual behaviour on the part of internal personnel. For example, an employee who tries to access unauthorized data, the system immediately identifies and takes measures (e.g. by forcing a break in network connections or limiting access).
4. Support for teleworking and BYOD management: safeguarding business flexibility and security
The company’s network security protection is more challenging with the spread of teleworking and the implementation of the BYOD (with its own equipment) policy.
