Businesses can take a number of steps to improve their security, and one of the most important is understanding zero trust security access. This term may be unfamiliar to some business owners, but it’s important to understand what it means and how it can help protect your company. In this guide, we’ll explain what zero trust security access is, why it’s important, and how businesses can implement it. Stay safe!
What is ZTNA?
ZTNA is a chip that stores the private key of a digital certificate, implemented in Infineon’s XTr-B hardware security module (HSM). ZTNA is designed to be used with the TPM of Infineon XS1. The main use for ZTNA is to help reduce the cost of a server by allowing it to store cryptographic keys and certificates.
These are needed to bootstrap a secure operating system at manufacturing time. The server manufacturer can then issue certificates that allow access to business assets, such as databases and web servers. This allows an organization to use the same server for different applications, minimizing the number of servers they need to purchase.
In addition, ZTNA provides an additional layer of security by requiring the use of a smart card or TPM version 2.0/2.1 device to bootstrap an operating system with a key stored in ZTNA. This requires an attacker who might compromise the operating system (via some other method). Also, they steal or guess a smart card or TPM device in order to access business assets.
ZTNA is used in combination with TPM 2.0 or 2.1 devices to store cryptographic keys and certificates. Also, you can use it to store password-protecting access to the immobilizer function of a vehicle’s engine.
ZTNA and VTN Security Management
VTN is a security management system on a set of procedures and protocols that allow a user to manage the different security policies in a network. Also, VTN uses the discovery protocol BGP4-MIB (RFC 2863). This is to obtain information about the other routers that exist on the same network. VTN provides a set of commands that allow a user to manage the different policies by means of a command-line interface (CLI).
In order to use the service, each network must be configured with a set of parameters that define its characteristics. These parameters are called network descriptors. VTN also has an authentication mechanism that allows any user who is not allowed to access the CLI to perform certain actions based on his or her privileges.
The VTN is divided into several modules, each of which has a specific function. The modules are as follows.
Security Module
These modules work together to provide the services that VTN provides to the user. The following are some of the benefits of using ZTNA and VTN security systems in an enterprise. So, ZTNA is a chip that stores the private key of a digital certificate.
Moreover, it is implemented in Infineon’s XTr-B hardware security module (HSM). ZTNA is designed to be used with the TPM of Infineon XS1. Thus, the main use for ZTNA is to help reduce the cost of a server by allowing it to store cryptographic keys and certificates. These are needed to bootstrap a secure operating system at manufacturing time.
So, the server manufacturer can then issue certificates that allow access to business assets, such as databases and web servers. This allows an organization to use the same server for different applications. Thus, minimizing the number of servers they need to purchase.
