2. How Zscaler’s Zero Trust Exchange Works
Zscaler’s Zero Trust Exchange is a cloud-native platform that connects users directly to applications, not the network. This approach minimizes risk and delivers fast application access.
2.1 What is Zero Trust Network Access (ZTNA)?
Zero Trust Network Access (ZTNA) is a security model based on the principle of “never trust, always verify.” Unlike traditional VPNs that grant users access to the entire network, ZTNA provides granular access to specific applications. This means that users only have access to the resources they need, reducing the attack surface and preventing lateral movement by attackers.
2.2 Key Components of the Zero Trust Exchange
The Zero Trust Exchange consists of several key components:
- Zscaler Internet Access (ZIA): Secures user internet traffic and enforces internet usage policies.
- Zscaler Private Access (ZPA): Provides secure access to private applications without exposing the network.
- Zscaler Cloud Firewall: Offers advanced threat protection and network security.
- Zscaler Data Loss Prevention (DLP): Prevents sensitive data from leaving the organization’s control.
2.3 The Four-Step Process of Zscaler’s Risk Management
Zscaler uses a four-step process to manage risk and ensure protection:
- Identity Verification: Integrates with third-party identity providers to verify the identity of users and devices.
- Destination Identification: Identifies the destination of the connection, such as a website, SaaS app, or private app.
- Risk Assessment: Uses AI to assess the risk based on factors like user behavior, device posture, content, and third-party threat intelligence.
- Policy Enforcement: Enforces security policies on a per-session basis, evaluating each connection in real-time.
2.4 How Zscaler Analyzes Data for Security Checks
Zscaler analyzes data from user activity, application access, network traffic, and threat detections to:
- Reduce latency and speed up access to cloud services.
- Direct network traffic to the fastest and most reliable paths.
- Cache frequently accessed content to reduce load times.
- Ensure vital applications receive the necessary bandwidth.
