Zero Trust Architecture
The proliferation of cloud computing, mobile devices, and bring-your-own-device (BYOD) policies is transforming the technological landscape of modern businesses.
Traditional security architectures relied on virtual private networks (VPNs) and network firewalls for protection. However, these measures are insufficient to safeguard organizations against advanced cyber threats. While these architectures restrict access to company resources and services, they are inadequate for employees needing access to applications and resources beyond the boundaries of the internal network.
As organizations migrated to the cloud and threats evolved, adopting a zero-trust security model became necessary.
Looplex was born as a cloud-first solution and organizational architecture company, and therefore adheres to this principle for SecOps.
Zero trust is based on the principle of proven trust—before trusting, you must first verify. This approach removes the inherent trust typical of legacy systems and internal networks. A zero-trust architecture reduces risk across environments through:
- Configuring strong authentication.
- Verifying device compliance before granting access.
- Always ensuring least-privilege access, allowing only explicitly approved resources.
Zero trust requires verification of all transactions between systems, including user identity, network, applications, and devices. The system must validate a transaction and ensure it is trustworthy before allowing it to proceed. Ideally, a zero-trust environment should include the following:
-
Multifactor Authentication (MFA) — A mechanism to validate and secure identities. It eliminates password expirations and potentially passwords themselves. Biometric authentication can also establish strong user-backed identity validation.
-
Device Health Validation — Validating the health of all device types. Systems must meet the minimum required health state before being granted access to any Looplex resources.
-
Data and Telemetry — Utilizing these inputs to understand the current security state, assess the impact of new controls, correlate data across services and applications, and identify coverage gaps.
-
Least Privileged Access — Limiting access to the minimum necessary resources (applications, infrastructure, and services) required to perform a job function. We avoid solutions offering unscoped access to specific resources or broad access without segmentation.
At Looplex, we embrace a DevSecOps culture, integrating the SecOps team within the platform development and support teams. Among the development team members, two are dedicated to Information Security and Operations, supported by an external consulting firm (Select Soluções) and the digital services of Microsoft Defender 365.
Microsoft Defender 365 provides a suite of enterprise defense services that natively coordinate detection, prevention, investigation, and response across endpoints, identities, email, and applications, delivering integrated protection against sophisticated attacks.
