Employees are not limited to the office building like in the old days. The remote working had effects on literally everything. Organizations today need a comprehensive security strategy to manage the complexities of securing the data.
From perimeter-based security to Zero trust architecture, we have come a long way. Let us look into how everything used to be and how everything is today.
There was a time when the organizations only had to secure just the perimeter and everything inside that was counted as a trusted device or person. With time, technologies evolved and we have measures to secure each device/person within the perimeter.
In Perimeter based security: 1. External access is untrusted
2. Internal access is trusted
With remote working, organizations no longer have the perimeter, and made the attack surface increase. Excessive trust is always the main challenge to overcome and that is what the Zero-Trust model addresses.
Zero Trust is an advanced tactic intended to secure data and information by continuously verifying every digital interaction and avoiding implicitly trusting any access requests. The Zero-Trust model is built on a foundation that says, “NEVER TRUST, ALWAYS VERIFY”. No device or person is trusted by default, regardless of the location – whether within or outside the security perimeter.
The basic principles of the Zero Trust model are:
This model assumes every incoming request into the network as a breach and looks at that request as it is from an unauthenticated source. So the response to the request is provided only if that request is proved to be from a trustworthy source. Under the zero trust model, all traffic should be:
Organizations are allowing employees to access business assets from remote devices and locations. So, organizations can no longer trust everything within the security parameter is secure. Regardless of where the request originates from, companies should secure connections to the business resources.
With users and devices moving outside the enterprise perimeter, the business processes driven by digital transformation are increasing the risk exposure. The need to think of some strategy other than “Trust but verify” was inevitable.
To protect data, and securely provide access to devices and users from wherever they are, organizations needed a new strategy. The zero trust model can be called a powerful strategy to stand protected in the competitive market.
Zero trust controls should be implemented into all fundamental elements which are:
Organizations should ensure that their data is kept safely to be recognized in the competitive business market.
