As the information process accelerates, the enterprise’s network environment becomes more complex. The way equipment and users access networks changes, traditional firewalls and intrusion detection systems are no longer able to meet the diversified needs of businesses for network security.
Challenges faced by enterprises in selecting NAC systems
In selecting suitable network access control systems, enterprises often face the following challenges:
-
Complexity of equipment types and network architecture
The enterprise’s network architecture is becoming more complex, especially with the introduction of technologies such as cloud computing, big data analysis, mobile officeing and so on, and the diversity of equipment types, access modes and business needs in the network. Equipment from computers issued by companies to smart phones brought by employees, tablets, etc., varies from one device to another, security requirements and certification. In addition, new working models such as teleworking, BYOD (with their own devices) and cross-geographic collaboration impose greater flexibility on NAC systems.
-
Compliance needs in different industries
Enterprises in different industries and regions may face different legal and compliance requirements. For example, the medical sector needs to comply with privacy protection requirements of the HIPCA (United States Health Insurance Portability and Liability Act) and the financial industry needs to meet security standards for PCI-DSS (the data security standards for payment cards).
-
Budget and implementation difficulties
While NAC systems provide comprehensive security for businesses, their implementation and maintenance may require higher inputs. Many enterprises, especially small and medium-sized enterprises, often need to weigh the actual impact of budgets and systems when considering introducing them.
How to select the right NAC system
In the face of these challenges, enterprises should consider a combination of factors when choosing network access control systems to ensure that they are selected for NAC systems that best suit their needs.
1. Support for multiple access modes and types of equipment
As the enterprise network environment changes, supporting multiple access modes and types of equipment becomes an important criterion for selecting NEC systems. Enterprises may need to have access to networks through wireless networks (Wi-Fi), VPNs, 4G/5G, etc., with equipment such as desktop computers, notebooks, mobile phones, tablets, and employee-held devices that they distribute.
This advantage is given by NAC, which can adapt to the enterprise's complex network environment, whether it be internal or outer networks or employee equipment connected through multiple channels such as wireless and VPN. The NAC system can be managed one-stop and ensure that all equipment meets security requirements.
2. Flexible access control strategy
The NAC system needs to support flexible and sophisticated access control strategies, as the demand for access to network resources varies between users and equipment in enterprises. Role-based access controls (RBAC), equipment health checks, geographical location restrictions, etc., ensure that only staff and equipment meeting security requirements can access the company’s networks and can effect dynamic adjustments.
Enterprises should choose to support the MAC system, which is controlled by fine-particle access, and can use intelligent control of access rights to prevent unauthorized equipment from accessing sensitive data, based on the identity of the employee, position, equipment state and geographical location of access.
3. Compliance support and audit function
Compliance support means that NAC systems not only meet the basic safety requirements of the industry, but also generate detailed audit logs that allow enterprises to check access to records and equipment at all times and ensure compliance with relevant laws and regulations.
NAC, NATSHEL_BRAND, is tailored to customised solutions for compliance requirements across industries and not only supports a wide range of industry standards (e.g. PCI-DSS, HIPAA, etc.), but also provides adequate audit functionality to help enterprises achieve compliance management.
4. Extendability and flexibility
The size of the enterprise and network needs will change over time, and it is vital to select a well-extensible NAC system. As business development increases the number of equipment and users connected to it and changes in network architecture may occur, NAC systems should have a stronger capacity to expand to cope with future network changes without frequent replacements.
NAC at NatShell is modular and flexible in its design. Whether it supports larger-scale equipment management or secure cross-geographical access, NAC at NATSHEL_BRAND can help to smooth the transition to a new network environment by integrating seamlessly.
5. User-friendly interfaces and ease of use
A manageable and operational NAC system can significantly reduce the cost of a company’s support. Selecting a system with a simple, visual management interface enables network administrators to quickly configure, monitor and manage network security. NAC systems not only need strong functionality but should also ensure their ease of use in order to reduce deployment and maintenance difficulties.
NAC at NatShell provides a graphical management interface, simplifying the management process and allowing network administrators to easily monitor network access, set access strategies, view security reports, etc. Both daily and in response to sudden security incidents, managers can respond quickly to ensure that businesses are secure.
