Your network security is under threat. What NAC solutions should you consider?

由人工智能和领英社区提供技术支持

Network security is a crucial aspect of any organization's IT infrastructure, especially in the era of remote work, cloud computing, and cyberattacks. However, managing and enforcing network security policies can be challenging, especially when dealing with diverse and dynamic devices, users, and access scenarios. That's why you need to consider Network Access Control (NAC) solutions, which can help you protect your network from unauthorized or compromised devices and users. In this article, you will learn what NAC is, how it works, and what types of NAC solutions are available for your network security needs.

1 What is NAC?

NAC stands for Network Access Control, which is a set of technologies and processes that allow you to control who and what can access your network. NAC can help you prevent unauthorized or non-compliant devices and users from accessing your network resources, such as servers, applications, or data. NAC can also help you monitor and enforce network security policies, such as device authentication, encryption, antivirus, firewall, or patch levels. NAC can also help you isolate and remediate any devices or users that pose a security risk to your network.

NAC is a network access control such as registering approved laptops or desktops on the corporate network. If not, you should let the security team know if there is the possibility of registering the device on the network.

2 How does NAC work?

NAC works by implementing a set of rules and actions that determine how devices and users can access your network. NAC typically involves four main steps: identification, authentication, authorization, and enforcement. Identification is the process of recognizing the device and user that are trying to access your network. Authentication is the process of verifying the identity and credentials of the device and user. Authorization is the process of granting or denying access to the network based on the device and user attributes and the network security policies. Enforcement is the process of applying the appropriate network access level and security measures to the device and user.

An example of this situation is corporate networks. As each company has the contract with x element, for example, Lenovo or Dell. It is important to have control over assets and validate the Mac Address of each

3 What are the benefits of NAC?

Network Access Control (NAC) can offer several advantages for your network security, such as improving visibility and control over remote, mobile, or personal devices and users. It can also reduce the risk of data breaches, malware infections, or network disruptions caused by unauthorized or non-compliant devices and users. Additionally, NAC can help you comply with regulatory standards, such as HIPAA, PCI DSS, or GDPR, by guaranteeing that only authorized and compliant devices and users can access sensitive data or systems. Furthermore, NAC simplifies network management and administration by automating and centralizing network access policies and actions.

I think the implementation of NAC is very important, as this way we know who is registered on the corporate network through MAC Address.

4 What are the challenges of NAC?

NAC can also present some challenges to your network security, such as increasing the complexity and cost of your infrastructure due to the need for additional hardware, software, or services. Furthermore, there may be compatibility and interoperability issues with different types of devices, operating systems, applications, or protocols that may not be compatible with NAC standards. Additionally, there is a delicate balance between security and usability that must be maintained to ensure that your network access policies are not too restrictive or intrusive for legitimate users and devices.

5 What are the types of NAC solutions?

NAC solutions vary in terms of their architecture, functionality, and deployment options. Agent-based NAC requires installing a software agent on each device to access the network, while agentless NAC does not require an agent, but instead relies on other methods such as network scans or MAC addresses. Hybrid NAC combines both agent-based and agentless NAC to offer more flexibility and scalability. Agent-based NAC can perform identification, authentication, authorization, and enforcement functions, as well as report device status and compliance to a central server. Agentless NAC is less intrusive and more compatible with different devices, but also less granular and more dependent on network infrastructure.

Embrace the reality that any connected device is a potential security risk. Resist the 'always connected' mindset. Identify operations that can function offline and pinpoint physical infrastructure areas where controlled disconnections can thwart attackers by cutting off their command and control channels. A crucial step is to disconnect white-collar and management job-related endpoints outside business hours, reducing exposure by 76%. Additionally, consider implementing Dynamic AirGapping procedures, like using Goldilock's #Drawbridge technology, for an added layer of security through physical isolation of critical systems.
