Before being permitted or maintaining access to applications and data, all users, whether inside or outside the organization’s network, must be verified, authorised and continually checked for security configuration and posture. Zero Trust presupposes that there is no typical network edge; networks can be local, cloud-based, or a blend of the two, with resources and workers located anywhere.

For today’s modern digital transformation, Zero Trust is a framework for safeguarding infrastructure and data. It specifically addresses today’s business concerns, such as securing remote workers, hybrid cloud systems, and ransomware attacks. While several suppliers have attempted to define their own terms.

Why adopt a zero-trust security model?

Cybercriminals targeting business-critical and sensitive data, such as personally identifiable information (PII), intellectual property (IP), and financial information, may find cloud settings appealing targets.

Even though all data breaches will never be completely eradicated, and no security plan is perfect, zero trust remains one of the most effective security solutions today. Zero trust minimizes the attack surface and negates the effect and intensity of cyberattacks, saving time and money in the aftermath of a breach.

Benefits of zero trust

1. Minimize company and organizational risk

Zero trust solutions prevent all apps and services from communicating until their identity attributes—immutable qualities that comply with predefined trust rules like authentication and authorization—are confirmed.

As a result, zero trust decreases risk by revealing what’s on the network and how those assets communicate. After baselines are established, a zero-trust strategy reduces risk by eliminating overprovisioned software and services and reviewing the “credentials” of every communication asset on a regular basis.

2. Take command of cloud and container environments.

Security professionals’ biggest concerns about going to the cloud are access management and visibility loss. Despite improvements in CSP security, workload security is still a shared responsibility between your company and the CSP. However, you can only influence so much within the CSP’s cloud.

Security policies are imposed depending on the identity of communicating workloads and are related directly to the workloads themselves in a zero-trust security architecture. This keeps security as close to the assets that need to be protected as feasible, independent of network constructions like IP addresses, ports, and protocols. Protection follows the workload and remains consistent when the environment shifts. 

3. Reduce the possibility of a data breach

Every entity is assumed hostile based on the concept of least privilege. Before “trust” is provided, each request is examined, users and devices are authenticated, and permissions are evaluated. As the context changes, such as the user’s location or the data being accessed, this “trust” is regularly reviewed.

An attacker who gains access to your network or cloud instance via a compromised device or other vulnerability will be unable to access or steal your data if you lack trust. Furthermore, the attacker will have nowhere to go because the zero-trust architecture produces a “safe section of one” with no way to move laterally.
