Question 1

What is Network Access Control (NAC) Software?

Accepted Answer

Network access control (NAC) software, as the name suggests, enables organizations to enforce policies and ultimately control access to their corporate networks. It’s also referred to as network admission control software or NAC software. 
 NAC systems strengthen network infrastructure security and reduce the risks associated with the exponentially growing number of endpoint devices. By enforcing policies on endpoint devices, NAC solutions can restrict access to enterprise networks and, at the same time, offer real-time network visibility. 
 One of the most common ways NAC software prevents insecure devices from infecting a network is by restricting access. NAC tools deny access to non-compliant devices to the network and, in most cases, place them in a quarantined network segment. In some cases, such non-compliant devices are offered restricted access to computing resources, thus reducing the chance of infiltration. NAC platforms can enhance network performance as well. Companies can also use them to create role-specific bandwidth rules. 
 NAC solutions can be viewed as a bouncer that decides who enters a business’ network. It does it by making sure the user is on the list, adheres to the network security policies of the company, etc. Different users are treated differently based on their level of access. The company can also restrict users who receive access to the network from accessing specific network resources or areas. 
 In other words, NAC solutions can help safeguard a private or proprietary network and protect its resources and user data. Companies can also use NAC systems as a discovery tool that lists all users, devices, and their access levels. Businesses can use it further to uncover previously unknown or non-compliant devices that have access to the network.

Question 2

What are the Common Features of Network Access Control (NAC) Software?

Accepted Answer

Manually configuring all the devices in use is a herculean task, especially for larger organizations with thousands or millions of users and devices. This has become even more troublesome with the widespread adoption of policies like bring your own device (BYOD) and the increasing use of internet of things (IoT) devices. The features offered by network access control tools can help companies adapt to such innovations or changes and stay secure. The following are some standard features of NAC systems. 
 Policy lifecycle management: NAC solutions can help enforce policies for all end-users and devices across an organization. The policy management feature of these tools allows companies to adjust policies based on changes to the business and in endpoint devices or users. 
 Profiling: This feature allows companies to scan and profile end users’ devices to ensure they aren’t potential threats. The software denies access to any unauthorized user or device. This is useful to forestall malicious actors from causing any damage to the network infrastructure. 
 Security check: NAC systems usually include a policy that assesses and authenticates end-users and devices. This security check can be in the form of verifying login credentials. If an endpoint device follows the security policy, it’s granted network access; otherwise, it’s viewed as a threat. 
 Visibility: NAC solutions offer features that allow IT administrators to view the type of devices being connected to the network. Administrators can view whether a device is wireless or wired or where it’s connecting from. 
 Guest network access: Not all non-compliant devices are threats; some could belong to guest users. The guest access feature makes it effortless to manage guest devices, including registration and authentication. The best NAC software will help provide guests with safe and controlled access to network resources, the internet, or other components like printers, without exposing other parts of the network. Some solutions also offer self-service device onboarding for automated device provisioning and profiling.

Question 3

What are the Benefits of Network Access Control (NAC) Software?

Accepted Answer

Network access control tools can make it easier to authenticate users and determine whether their devices are safe and compliant. These software solutions reduce the time and cost associated with authentication and authorization and make cybersecurity approachable. The following are some of the common benefits of using NAC software: 
 Have ease of control: NAC solutions make it possible to monitor and authenticate endpoint users and devices from a single, centralized security management system. The centralized admin console also streamlines detecting suspicious network activity and initiating remediation measures. Businesses can easily regulate the limit to which any user can use the network resources. NAC tools also allow large enterprises to segment their employees into groups based on their job functions and set up role-based access policies. 
 Automate incident response: Incident response, or IR for short, is a set of security policies and procedures that can be utilized to identify, isolate, and eliminate cyberattacks. NAC tools can help automate IR and significantly reduce the intensity of cyberattacks. 
 Improve security: An obvious benefit of NAC software is that it enhances the security posture of organizations by preventing unauthorized access and malware threats, or in other words, by enforcing zero-trust security postures. Since the solutions authenticate every network device, there’s improved visibility. NAC solutions are also typically capable of improving endpoint security against known vulnerabilities. 
 Save costs and time: Cyber threats can cost companies millions of dollars. Adding to this is the cost associated with reduced confidence by customers and loss of opportunities. With the increasing number of cyberattacks, companies need to establish NAC to protect their data and stakeholders. Along with saving costs, NAC tools save time by eliminating the need for manual configuration of devices. 
 Provide a better user experience: Along with freeing up IT administrators, NAC software enhances the end-user experience. With a NAC solution in place, users are more likely to trust an organization’s network and feel secure. Guest users will have a better, frictionless experience as well as they don’t have to engage with the IT department to connect to the network. 
 Centralize access control: NAC platforms can elevate user experience by offering centralized access control. As the name suggests, this feature allows users to access all IT assets, including applications, websites, and computing systems, with a single set of credentials. 
 Generate reports: NAC software empowers IT administrators to generate reports about attempted access throughout the organization. Such reports could help understand what authentication mechanisms work the best and, at the same time, can help detect malicious actors.
