What is a Networked Access System? A NAC solution controls network access and prevents access by unauthorized users, insecure devices, and others from infecting the network.
The NAC solution is designed to handle large enterprise networks that contain a wide range of devices. As a result, it can prevent large cyber attacks from damaging a business’s network and limit its damage.
Today’s organizations are faced with a growing number of endpoint devices. These devices create an increased attack surface and increase the number of opportunities for cybercriminals. A Networked Access System (NAC) solution will detect unauthorized access to the network and isolate suspicious devices for investigation. In addition, it can protect the organization against attacks and prevent non-compliant devices.
Integrated with an enterprise network security architecture, NAC solutions block unauthorized access, non-compliant devices, and other threats. Networked Access
System solutions block attacks, unauthorized access, non-compliant devices, and other hazards while simplifying and centralizing policy management. A single NAC can support multiple network security policies, block non-compliant devices and users, and prevent malware and spyware installation.
Whether your organization has hundreds or thousands of endpoints, NAC solutions can help you protect against these threats. These solutions are also highly flexible, allowing you to set policies that govern access for different categories of endpoints.
NAC can even grant temporary access to non-employees. These features are critical for protecting your company and the data on them.
2. They provide visibility, access control, and compliance capabilities.
With the increasing number of endpoint devices on networks, network access control (NAC) unifies several elements of endpoint network security. For example, it typically grants access based on the user profile and considers the user’s authentication.
If the user is unable to authenticate themselves, NAC prevents access. The benefits of network access control are apparent, making the implementation process more efficient.
NAC enables organizations to monitor all devices connected to the network. It blocks initial connections to the network, authenticates users, and evaluates the security posture of devices.
NAC enables IT, administrators to reduce security costs by automating the process of tracking devices. These NAC solutions also minimize the number of IT staff needed to manage these devices. Further, they reduce the risk of cyberattacks and malware.
3. They can handle large enterprise networks.
Enterprise networks contain multiple types of devices that are constantly connected to the corporate network. These networks provide fixed and mobile access to people, applications, and information.
They connect physical and virtual buildings and provide mission-critical reliability and security. In addition, these networks handle the growing number of connected endpoints, ranging from biometric-enabled smart doors to IP-enabled printers.
NAC products are built specifically for large enterprise networks, which typically have various devices. Without NAC, companies are taking a huge risk by implementing a “bring your own device” (BYOD) policy, which allows employees and vendor devices to access the network.
Although NAC solutions require an upfront investment, they will ultimately pay for themselves in the long run. This is because they provide companies with comprehensive control over access and data on their networks.
4. They can limit the damage from a cyber attack.
By 2021, the global economic impact of cybercrime is expected to reach $6 trillion, exceeding the yearly cost of natural disasters. The economic costs of cybercrime can be devastating to individual companies.
A typical cyberattack costs a company $1.67 million, but that amount can grow much higher. The primary consequences of a cyber attack are operational loss, lost productivity, and a negative customer experience. A networked access system is one way to limit the damage that a cyber attack can cause.
Cyberattacks are attempts by hackers and others to disrupt or steal information from a computer system. They use illegal tools and approaches to gain unauthorized access to computers and the information they contain.
Depending on the type of cyberattack, a networked access system can help limit the damage. Cyberattacks can affect everything from transportation to the power grid. If your computer is vulnerable, you may be at high risk for a cyber attack.
