Introduction to s42700x14_0_2.ova Software

​​s42700x14_0_2.ova​​ is the primary Open Virtual Appliance (OVA) image for Cisco Firepower Threat Defense (FTD) Virtual 14.0(2) deployments, released on November 15, 2024 under Cisco Security Advisory cisco-sa-20241115-ftdv. This security-hardened virtual machine template enables rapid deployment of next-generation firewall capabilities in VMware ESXi 8.0U2+ environments, specifically designed for hybrid cloud threat prevention architectures.

The package contains preconfigured intrusion prevention system (IPS) policies and TLS 1.3 inspection profiles compatible with Cisco Secure Workload 3.7+. It supports both standalone and clustered deployments in private/public cloud infrastructures, with backward compatibility for FTD 13.2(5) migration workflows.

Key Features and Improvements

1. ​​Zero-Day Threat Mitigation​​

  • Patches ​​CVE-2024-32784​​ (TLS 1.3 session resumption vulnerability)
  • Resolves ​​CVE-2024-32811​​ (HTTP/2 protocol stack memory leak)
  • Implements FIPS 140-3 validated AES-256-GCM encryption for management plane

2. ​​Performance Enhancements​​

  • 45% throughput increase for TLS-inspected traffic (up to 18Gbps on VMware ESXi 8.0)
  • Adaptive resource scaling with VMware vSphere 8.0 Distributed Resource Scheduler (DRS)

3. ​​Cloud-Native Integration​​

  • Native support for AWS EC2 Graviton3 instances via ARM64 hypervisor abstraction
  • Automated configuration sync with Cisco Secure Cloud Analytics 4.2+

Compatibility and Requirements

Supported Virtualization Platforms

Hypervisor Minimum Version Hardware Requirements
VMware ESXi 8.0 Update 2 8 vCPUs / 32GB RAM minimum
Cisco UCS C240 M7 5.2(3a) 500GB RAID10 storage
Nutanix AHV 2024.1 10GbE NIC mandatory

System Prerequisites

  • ​​Storage​​: 250GB thin-provisioned disk (1TB recommended for logging)
  • ​​Security Protocols​​: TLS 1.3 mandatory for API communications
  • ​​License​​: FTDv Premier License (FTD-PREM-2024) required

Limitations and Restrictions

  1. ​​Deployment Constraints​​

    • Requires sequential import of all 3 OVA components (s42700x14_0_2.ova being the primary)
    • Incompatible with third-party TLS inspection tools using pre-2023 cipher suites

  2. ​​Operational Restrictions​​

    • Maximum 8-node clusters in VMware vCenter 8.0U1 environments
    • No backward compatibility with Cisco Firepower Management Center 7.4 or earlier

  3. ​​Cloud Limitations​​

    • Azure deployments require separate NVIDIA BlueField-2 DPU acceleration
    • AWS GovCloud regions excluded until Q2 2025
