By now, you have guessed which network security model saves people daily from hackers – the zero-trust model. Ever since this approach came into being, it has been a hot topic of discussion in security circles. So, how does it help companies to stay safe? In this article at TechTarget, Sandra Gittlen and Laura Fitzgibbons share how this network security model works. They also discuss the architecture and implementation methods as well.
A Network Security Model to Reduce Breaches
The Zero-Trust Definition
When companies place too much trust in individuals or systems, hacking is bound to happen. The authors assert, “no user, even if allowed onto the network, should be trusted by default because they could be compromised.” That is what the zero-trust model is all about.
Significance of the Network Security Model
Though VPNs and firewalls are in place, they only allow access to known individuals and systems. Since people work in remote locations, the perimeter approach does not help. A zero-trust approach enhances data protection, improves auditing, and reduces breaches and identification challenges. The network security model also increases network visibility and provides much better control of the cloud setup.
The Workings of ZTNA
Zero-trust network access (ZTNA) is a section of the zero-trust model that authenticates you based on your identity but hides the IP address. This helps remote users to stay safe without the fear of hackers discovering their network location.
The network security model is not a one-stop product that you should implement. It is a mindset and a decision, per IEEE senior member Jack Burbank. However, independent analyst John Fruehe says implementing it in non-critical workspaces would be too much.
The network security model can protect third parties integrated into your corporate architecture. Additionally, remote workers can access your company’s cloud database without worry. Lastly, you will get IoT security and prominence. Per a joint report by Cybersecurity Insiders and Pulse Secure, organizations with a zero-trust model received continuous authorization, better trust among employees and customers, and data protection.
Different Than SDN and VPN
Software-defined perimeter (SDP) and virtual private network (VPN) are popular network security models too. Though the three models seem not to work well with each other, you can develop strategies to make these collaborate well.
Though it is not available in a single application or product, you can create a zero-trust environment through specific tools. For instance, security tools for the workforce, devices, networks, data, analytics, etc., can build a robust setup.
Executing the Model
If you want to adopt zero-trust as your network security model, assemble a group of security and network professionals. The security professionals will develop and maintain the framework. Meanwhile, the network team will take care of the network architecture.
