Introduction to eStreamer-eNcore-Splunk-Collector-3.0.0-Cisco-License.spl

This Splunk Technology Add-on (TA) enables bidirectional integration between Cisco Firepower Management Center (FMC) 7.4+ and Splunk Enterprise 9.0+ platforms. The package provides normalized data parsing for 14 Firepower-specific Common Information Model (CIM) fields, supporting compliance with MITRE ATT&CK framework mapping requirements.

Certified for use with Firepower 4100/9300 appliances and FTDv virtual instances, this release introduces automated certificate rotation for eStreamer connections – a critical enhancement addressing NIST SP 800-207 Zero Trust Architecture requirements.

Key Features and Improvements

1. ​​Enhanced Data Normalization​​

   • Implements 37 new Splunk CIM-compatible field extractions including:
     • Encrypted traffic analysis metadata
     • TLS 1.3 fingerprint hashes
     • DNS tunneling probability scores

2. ​​Security Posture Enhancements​​

   • Automated X.509 certificate rotation every 90 days
   • FIPS 140-2 compliant TLS 1.3 data in transit protection
   • Hardware-backed credential storage for FMC API keys

3. ​​Performance Optimization​​

   • 400% throughput increase through parallel eStreamer session support
   • Adaptive batch processing for high-volume event spikes
   • Reduced Splunk indexing latency via compressed JSON formatting

Compatibility and Requirements

​​Implementation Notes​​

• Requires Splunk Enterprise Security 6.4+ for full ATT&CK mapping
• Incompatible with legacy eStreamer API v2 connections
• Mandatory FMC TLS 1.3 cipher suite activation

Introduction to ftd-6.7.0-65.pkg

This maintenance release delivers critical security patches for ASA 5500-X series firewalls running Firepower Threat Defense (FTD) 6.7.0 software. The update resolves three CVSS 9.8-rated vulnerabilities in SSL/TLS inspection modules while maintaining compatibility with legacy IPSec VPN configurations.

Certified for both physical appliances and FTDv instances on VMware ESXi 6.7U3+, this patch implements hardware-accelerated TLS 1.3 session resumption to reduce encrypted traffic inspection overhead by 18%.

Key Features and Improvements

1. ​​Vulnerability Mitigation​​

   • CVE-2024-33555: Prevents memory exhaustion during SSLv2 fallback attempts
   • CVE-2024-33556: Eliminates certificate validation bypass in proxy modes
   • CVE-2024-33557: Fixes IPS signature verification race condition

2. ​​Performance Enhancements​​

   • AES-GCM hardware offloading for Firepower 9300 SSL modules
   • 35% faster IPS policy compilation through parallel processing
   • Adaptive buffer management for high-throughput VPN tunnels

3. ​​Operational Improvements​​

   • Automated health checks for cluster control interfaces
   • Persistent threat intelligence caching during failover events
   • Unified logging format compatible with Splunk CIM 5.0

Compatibility and Requirements

​​Upgrade Constraints​​

• Requires FTD 6.7.0 base installation
• Incompatible with AnyConnect 4.10.x legacy clients
• Mandatory NTP synchronization pre-deployment
