2. Key Security Features of Cisco Catalyst 9300
2.1. Encrypted Traffic Analytics

• Overview: The Catalyst 9300 series supports Encrypted Traffic Analytics (ETA), which provides visibility into encrypted traffic without needing to decrypt it. This allows organizations to monitor and analyze encrypted data for potential threats.
• Benefits: Organizations can detect malicious activities hiding within encrypted traffic, enhancing overall security without compromising user privacy.

2.2. Cisco TrustSec

• Overview: Cisco TrustSec is a security architecture that enables role-based access control (RBAC) to secure users, devices, and applications. It simplifies network segmentation and enforces security policies across the network.
• Benefits: TrustSec enhances security by ensuring that only authorized users and devices can access specific network segments, reducing the attack surface and preventing lateral movement within the network.

2.3. Advanced Network Segmentation

• Overview: The Catalyst 9300 allows for advanced segmentation using VLANs and Virtual Routing and Forwarding (VRF). This helps create isolated environments within the network to enhance security.
• Benefits: Segmentation minimizes the impact of security breaches by containing threats within specific segments, preventing them from spreading throughout the network.

2.4. Integration with Cisco Identity Services Engine (ISE)

• Overview: The Catalyst 9300 series integrates seamlessly with Cisco ISE, enabling centralized policy management and identity-based access control. This integration allows organizations to enforce consistent security policies across their networks.
• Benefits: Organizations can manage user access and device compliance effectively, ensuring that only authenticated and authorized users can access critical network resources.

2.5. Real-Time Threat Detection

• Overview: The Catalyst 9300 series supports advanced threat detection through features like Cisco’s Secure Network Analytics (formerly known as Stealthwatch), which provides deep visibility into network traffic and detects anomalies.
• Benefits: Real-time threat detection enables organizations to identify potential security incidents quickly, facilitating faster response and remediation.
