3 KEY ELEMENTS OF ZERO TRUST ARCHITECTURE.

 

Now let's discuss the key elements of a zero-trust architecture when evaluating a zero-trust architecture. There are three elements that should be considered these elements are vital to the successful deployment and construction of zero-trust architectures. They are

1. NO FALSE SENSE OF SECURITY.
2. MULTIFACTOR AUTHENTICATION.
3. MICRO-SEGMENTATION.

1. NO FALSE SENSE OF SECURITY:-

                                                            The first element is no false sense of security:- In traditional architectures, anything that happens inside the perimeter of a network is considered a trusted assumption being that any user or activity in the network has already passed authentication and is authorized to be there. This model assumes that perimeter security is flawless and that insiders are never malicious. To anyone familiar with security the flaws in this model should be obvious there are many situations in which users and events inside your perimeter are not to be trusted.                                                                                                                                                                                      For example, an attacker who has entered with compromised credentials or insider threats may abuse privileges or move laterally through the network a zero-trust architecture makes this understanding explicit and prioritizes protection against insider threats.

    2. MULTIFACTOR AUTHENTICATION:-

                                        In multi-factor authentication, we use credentials in a combination of an additional authenticator. For example, Requiring a user to scan their fingerprint or confirm a pin sent to a mobile device these will significantly reduce the chance that attackers are able to use compromised credentials to access your systems and data. A zero trust architecture implements multi-factor authentication as a double-check against its own security measures. It uses multi-factor authentication to ensure that users are who they claim to be and ensures that access and transactions are allowed correctly multi-factor authentication also plays a large role in PCI security which helps organizations protect credit card data in accordance with the PCI standard.

    3. MICRO-SEGMENTATION:-

                 Micro-segmentation is the use of access controls to isolate the various components and services in your system. It allows you to layer security measures such as firewalls or authorization measures for greater security it also lets you restrict access to assets on a granular level reducing the chance of an attacker taking advantage of lateral weaknesses. A zero trust architecture leverages micro-segmentation to ensure that even users or applications inside a network are properly restricted. It ensures that even if an attacker does enter the network the amount of damage they can cause is severely limited. Micro-segmentation and cloud-native development often go hand-in-hand however micro-segmentation by itself does not cover all of your cloud security needs. It's important to make the distinction between micro-segmentation as a security measure and cloud security as a whole.
