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.
