The benefits of a Zero Trust framework extend well beyond security.
FREMONT, CA: Zero Trust, Zero Trust Network, or Zero Trust Architecture are security ideas and threat models that do not automatically trust actors, systems, or services functioning within the security perimeter but instead require verification of everything attempting to connect to its systems. A Forrester Research security analyst coined the word.
The Zero Trust concept was developed in reaction to the discovery that the perimeter security method is ineffective since numerous data breaches occurred due to hackers easily breaching corporate firewalls and moving through internal systems. Additionally, the perimeter is no longer clearly defined because apps and data storage are now hosted on-premises and in the cloud, with users accessing them via various devices and locations.

Zero Trust is a broad approach that requires companies to employ micro-segmentation and granular perimeter enforcement based on individuals, their locations, and other data to determine whether to trust a person, machine, or application requesting access to a specific section of the enterprise.
Zero Trust leverages multi-factor authentication, identity and access management (IAM), orchestration, analytics, encryption, scoring, and file system rights. Additionally, Zero Trust requires governance norms such as granting users the least access necessary to complete a task.
Notification through Push Authentication facilitates user authentication by sending a push message directly to a secure application on the user's smartphone, notifying them of an authentication attempt. Users can often check authentication data and accept or reject access with the click of a button. Notifications can be sent in-band or out-of-band via various communication routes.
Push notifications to verify that the user is indeed in possession of the device registered with the authentication system - generally a mobile device. Push notifications are also impacted if an attacker exploits the device.
Push notification authentication is gaining popularity since it provides a convenient method of authenticating users, primarily when used with no passwords.
