With billions of devices now connecting to networks, the sharing of highly sensitive data creates new opportunities for information to be compromised. From connected healthcare devices, to smart buildings, to remote asset monitoring in manufacturing, all are powered by a growing diversity of networking technologies, creating substantial new security risks.
Coupled with the explosion in BYOD (bring your own device) and hybrid cloud environments bringing added threat opportunities, trusting antivirus tools or firewalls is simply not enough to secure the connected infrastructure and systems in today’s world of cyber attacks and data breaches.
Organisations need to mitigate risk with a zero trust approach, strict policy enforcement, increased user/device visibility, and complete network control.
The zero trust approach assumes that there will always be users or devices looking to attack, and that no user, and no device, should be automatically trusted.
Modern businesses need secure access solutions built around the Zero Trust model of continuous verification and authorisation – enforcing verification and validation whenever a user or device requests access, with the ability to control those devices and users. Network access control (NAC) is therefore essential to keep unauthorised users & devices OUT of private networks.
A Network Access Control (NAC) solution gives optimum visibility and control to organisations. It stores the organisation’s access policies and applies them to every access request that is submitted.
Therefore it can be configured to enforce a zero trust security policy, to deny access to users or devices and place them in quarantine, not only protecting the network but also ensuring regulatory compliance.
3 steps to securing your network access:
- Verify users when they sign on:
verification applies whether or not the device or user is already within the network as it can be triggered by events such as changes in the devices being used, location, log-in frequency, or the number of failed login attempts.
- Validate devices before they access networks:
ensure all devices meet the criteria of the security policy in order to gain full access to internal resources.
- Limit privileged access:
only giving the essential access to the resources they need, limiting entry to sensitive data or infrastructure
To find a suitable NAC solution, look for a platform that can integrate with your existing software as you don’t have to change your infrastructure in order to implement a NAC platform.
