Network Admission Control: Perks and its Significance

Network Admission Control

In the fast-evolving world of cyber security, businesses face an increasing challenge regarding threats that can compromise their sensitive data and disrupt operations. For the protection against these risks, organizations are turning to advanced solutions, and one such important tool is network admission control. Network admission control is a complete security protocol that boosts businesses to regulate and secure access to their networks. This article discusses the significance of network admission control and discovers how it can shape the cyber security posture of businesses.

What is network admission control?

Network admission control is a security process that ensures only authorized and compliant devices gain access to a corporate network. It acts as a shield to monitor and control the entry of devices to prevent unauthorized access and potential security threats. NAC regulates by measuring the security posture of devices seeking network access, enforcing security policies, and remedying any identified issues before granting access.

Evolving threats

As businesses become digitally dependent, cyber threats and breaches continue to increase at an alarming pace. Cybercriminals practice sophisticated tactics, making it imperative for organizations to implement robust security measures. Network admission control serves as an important component in this arsenal, providing a proactive defence against potential breaches.

Benefits of Network Admission Control

  • Access control

One of the major functions of network admission control is to regulate access to the network based on predefined security policies. Only devices that meet the specified criteria, such as up-to-date antivirus software and the latest security patches, are allowed to connect. This ensures that potential vulnerabilities are addressed before a device is granted access, reducing the risk of exploitation by harmful elements.

  • Endpoint compliance

NAC plays an important role in enforcing endpoint compliance. It assesses devices for compliance with security policies and automatically remediates non-compliant systems. By ensuring that all devices adhere to security standards, businesses can create a more resilient and secure network environment.

  • Threat detection and response

Network admission control includes advanced threat detection capabilities. It continuously observes network activity and identifies any susceptible behaviour that may cause a security threat. In the event of a potential threat, NAC can respond quickly by separating the affected device or taking other predefined actions to mitigate the risk.

  • Policy Enforcement

Network admission control allows businesses to define and enforce security policies consistently across the entire network. This ensures a uniform level of security and compliance, regardless of the variety of devices and endpoints seeking access. Policy enforcement is essential in maintaining a cohesive and secure network infrastructure.

  • Guest network security

Guest networks are often invited by businesses for deals and contracts. Network admission control extends its protective shield to these guest networks, ensuring that even external devices adhere to security policies before accessing the network. This is essential in preventing potential security breaches originating from guest devices.

Implementing network admission control

The implementation of network admission control includes a strategic and phased approach. Here are key steps for businesses looking to deploy NAC:

  • Assessment and planning

It starts with conducting a complete assessment of your network infrastructure and analyzing potential security vulnerabilities. Develop a full-fledged plan that outlines the specific security policies and criteria that NAC will enforce.

  • Policy definition

Clearly define security policies that align with your organization’s risk tolerance and compliance requirements. These policies should cover aspects such as antivirus software, operating system updates, and device configurations.

  • Integration with existing systems

Integrate NAC seamlessly with your established network infrastructure and security systems. Compatibility with other security tools ensures a holistic and synergistic approach to cyber security.

  • Training and Awareness

Educate and train your IT staff and end-users on the importance of network admission control and its importance in maintaining a secure network environment. Awareness is the most essential factor to the successful implementation and operation of NAC.

  • Continuous monitoring and adaptation

Cyber threats are dynamic, and security landscapes evolve. Implement continuous monitoring to stay ahead of emerging threats. Regularly review and update security policies to adapt to changing circumstances and technologies.
