Are you familiar with the Zero Trust security model? It’s a fairly new way of thinking about network security that is gaining in popularity. The Zero Trust Principles guide provides an overview of the model and offers tips for implementing it in your organization. If you’re interested in learning more, this guide is a great place to start!
Zero Trust Principles Explained
ZTNA is the paradigm shift that you need to understand to design and operate a secure network.
First, least privilege means every user should have the least privilege necessary to perform their job function. This means no accounts with administrative privileges.
Second, zero access means every user account should only have the access necessary for them to perform their job function. For example, there should be no external facing admin accounts. Third, zero-knowledge is where every user should not be able to access any data they do not need for their job function. For example, there should be no support staff with access to the production network.
Lastly, zero authentication is where every user should only be authenticated when they need to be, and only from a device, they need to use. For example, there should not be a VPN connection for every employee.

Vulnerability scanning and patching of all internal infrastructure like servers and network devices. This can be done using various security tools like vulnerability scanners and patch management software. Since this can be deployed using any spectrum of ITIL processes like request or incident management, change management, and release management.
It is to ensure that there are no unauthorized applications or services running inside the organization’s networks. This is like rogue DHCP servers, DNS servers, rogue wireless access points, etc. Also, it helps to detect unauthorized traffic in the organization’s networks for example if any user is accessing any website.
It is not authorized by the organization’s acceptable use policy (AUP). But it verifies if all users inside the organizations’ network are compliant with the organizations’ security policies. Also, if it granted access to only those applications and data which is authorized by the organization for them for their job function.
Moreover, this can be achieved by deploying UTM devices inside the organization’s network. But it performs authentication and authorization before allowing any legitimate user to access any application or data. This is over the internet or inside of the organization’s internal networks.
Centralized Security Operations
It is to monitor all activities inside the organization’s network and ensure they comply with the organizations’ security policies. So, no user is misusing their privileges or attempting to access any information or application. Since they are not authorized for.
Also, it ensures that all users inside the organization’s network are using a secure communication channel. That is between themselves and between themselves and other users outside of the organization’s network (internet). On the other hand, performing their job functions like accessing applications hosted on cloud platforms.
So, it uses various encryption mechanisms like SSL/TLS. It ensures that there is no malicious traffic entering the organization’s network from outside of it through any entry point like routers etc. Thus, it provides a centralized view of all security operations including audit logs for all security events generated by various security components deployed.
