Introduction to Cisco Secure Workload, Release 3.9.1.25

The Cisco Secure Workload platform is designed to provide comprehensive workload security by establishing a micro perimeter around every workload. The micro perimeter is available across your on-premises and multicloud environment using firewall and segmentation, compliance and vulnerability tracking, behavior-based anomaly detection, and workload isolation. The platform uses advanced analytics and algorithmic approaches to offer these capabilities.

This document describes the features, bug fixes, and behavior changes, if any, in Cisco Secure Workload, Release 3.9.1.25.

For information on how to upgrade the software version, see Cisco Secure Workload Upgrade Guide.


Note

As a best practice, we recommend to patch a cluster to the latest available patch version before performing a major version upgrade.

Release Information

Version: 3.9.1.25

Date: April 10, 2024

New Software Features in Cisco Secure Workload, Release 3.9.1.25

Feature Name

Description

Integration

Integration of Cisco Vulnerability Management for Deep CVE Insights with Cisco Risk Score for Prioritization

To assess the severity of common vulnerabilities and exposures (CVE), you can now view the Cisco Security Risk Score of the CVE, including the attributes on the Vulnerabilities page. Use Cisco Security Risk Score to create inventory filters, microsegment policies to block communication from the impacted workloads, and virtual patching rules to publish the CVEs to Cisco Secure Firewall.

For more information, see Vulnerability Dashboard, Cisco Security Risk Score-Based Filter, and Cisco Security Risk Score Summary.

Hybrid Multicloud Security

Visibility and Enforcement of Well-known IPv4 Malicious Traffic

You can now detect malicious traffic from workloads to well-known malicious IPv4 addresses. To block any traffic to these malicious IPs and to create and enforce policies, use a predefined read-only inventory filter Malicious inventories.

Note

 

This feature is disabled by default. To enable it:
