zero trustZero trust security can be defined as an IT security model that needs stringent identity verification for each device and person who tries to access any resource on a specific private network, whether they’re inside or outside the perimeter of the network. There’s no single technology that’s related to the zero trust architecture; it is a holistic method that involves network security, which uses various technologies and principles.

Conventional IT cybersecurity depends on the castle and most idea. In this type of security, it’s difficult to get access when you’re outside the network. But all those who are inside the network is considered as trustworthy, by default. The problem with this method is that when a hacker gets access to the network and gets inside the perimeter, he’ll be left to do whatever he wants inside.

This vulnerability is made much worse by the fact that companies keep their data in different places. These days, data is spread across different cloud vendors, which makes it a lot of more difficult to have one security control for the whole network.

With zero trust community, no one is considered trustworthy by default, both in and out of the network. Before access to the network’s resources is given, verification must be provided. This additional security layer has been shown to be effective at preventing data breach. A recent study that’s been sponsored by IBM showed that the average cost of one data breach reached at least 3 million. Given that figure, it’s no longer surprising that a lot of organizations are considering a transition to a zero trust security policy.



What are the primary principles and technologies behind a zero trust security?

The concept behind a zero trust network involves the assumption that there are attackers inside and outside the network, so no machine or user can be trusted automatically. Another zero trust security principle involves the least-privilege access. This implies that users are provided with as much access is required, such as an army general provide soldiers information only on a need to know basis. This will help minimize the exposure of every user to sensitive areas of the network.

Zero trust network also uses microsegmentation. It is the practice of dividing security perimeters into smaller zones to keep separate access for separate areas of the network.

Another core of the zero trust security is multifactor authentication. It requires users to provide more than one piece of evidence for authentication. For example, keying in a password is no longer enough. With MFA, users need to enter the password and a code that that is sent to a different device.

Aside from controlling user access, zero trust security also imposes strict control when providing access to devices. Zero trust systems must monitor how many different devices are trying to access their network as well as make sure that each of them is authorized. It helps minimize the network’s attack surface.

How to implement zero trust security?

Up until today, zero trust needs a comprehensive implementation by professional security engineers, concentrating on the main principles and technologies shared above. But things have been simplified thanks to companies such as SpartanTec, Inc. whose IT experts can help businesses transition to a zero trust network seamlessly and easily.
