Just a few years ago, you had to go to your office building to access your computer and network(s) – but mobile devices have changed all that. You can even “work from home” now. However, the mobility advantage comes with exponential cybersecurity risks. This scenario makes it critical to have tools to offer visibility, access control, and compliance capabilities that ensure a more robust network security infrastructure.
A Network Access Control (NAC) solution is the tool you need. This solution can automatically profiles devices, denies them network access if they are not compliant to your security requirements, and places them in quarantine or only enabling limited access to computing resources. It ensures that any device that connects to your network will be incapable of infecting your systems.
What are the capabilities of a Network Access Control Solution?
A NAC solution can help your business control its networks using the following capabilities:
Bidirectional integration
Interfacing with other security and network solutions through open/RESTful API.
Guest networking access
Manage and organize guests using a customizable self-service portal and includes guest registration, guest authentication, guest sponsoring, and a portal for managing guests.
Incidence response
Limit network threats by enforcing security policies that block, isolate, and fix non-compliant machines without administrator involvement.
Policy lifecycle management
Ensure adherence to policies for all circumstances without the need for additional products or separate modules.
Profiling and visibility
Recognize and profile users and their devices before malicious code can affect damage.
One NAC product will probably not be able to block all potential cyberattacks. However, it will go a long way to significantly lower the risk level of your company’s most sensitive data assets.
A Network Access Control Policy
By default, NAC tools can provide much value to your company by monitoring the network for attacks and threats. The system’s highest value is in building a network access control policy within it.
What’s a network access control policy? It’s a collection of specific rules for your company, dictating who can access what resources.
NAC for Vendors or Partners
In a fast-paced industry, success for an enterprise may depend on how easy it is for third-party vendors and partners to integrate. It could involve sharing of raw data feeds, but in many cases, true network-to-network integration is necessary for a seamless experience.
A slippery slope with network access controls is in providing network access to partners and vendors without making your business vulnerable to new channels of data security attacks.
A network access control solution usually includes a virtual private network (VPN) client so that external users can have access to internal resources via a secure channel. However, the NAC solution will log all activity for monitoring.
Should You Invest in a Network Access Control (NAC) Solution?
NAC solutions are valuable considering a digital climate replete with mobile devices and IoT. Their design allows them to handle large enterprise networks where several devices are trying to connect simultaneously,
Without a NAC, a bring-your-own-device (BYOD) policy will expose any company to untold risks. NAC systems such as Easy NAC offers robust BYOD protection.
