·&nbsp;&nbsp; Assess telecom security threats and vulnerabilities across Core, RAN, IMS, signaling, roaming, and interconnect environments.
·&nbsp;&nbsp; Identify security-relevant logs and events generated by telecom network elements and applications.
·&nbsp;&nbsp; Coordinate with OEM/vendor teams to enable appropriate security logging on telecom devices.
·&nbsp;&nbsp; Support onboarding of telecom devices and applications into the SIEM platform.
·&nbsp;&nbsp; Coordinate connectivity, routing, firewall, and log-forwarding prerequisites with relevant teams.
·&nbsp;&nbsp; Work with SIEM engineers on log validation, parsing, normalization, field mapping, and integration troubleshooting.
·&nbsp;&nbsp; Identify security-logging gaps and support remediation of missing, delayed, or incorrectly parsed events.
·&nbsp;&nbsp; Assist SOC/SIEM teams in defining telecom-specific security monitoring and detection use cases.
·&nbsp;&nbsp; Maintain telecom device inventory, logging requirements, integration details, and supporting technical documentation.
Mandatory Skills
·&nbsp;&nbsp; Strong understanding of 4G LTE and 5G architecture, including EPC and 5G Core.
·&nbsp;&nbsp; Knowledge of RAN architecture, IMS/VoLTE, and major Telecom Core network elements.
·&nbsp;&nbsp; Strong working knowledge of SS7, Diameter, GTP, and SIP.
·&nbsp;&nbsp; Understanding of telecom signaling security, network security, and security events.
·&nbsp;&nbsp; Hands-on telecom device and network troubleshooting experience.
·&nbsp;&nbsp; Knowledge of IP networking, TCP/IP, routing, DNS, and firewall fundamentals.
·&nbsp;&nbsp; Understanding of telecom network-element logs and device logging capabilities.
·&nbsp;&nbsp; Ability to collaborate across Telecom Network, OEM, Cybersecurity, SOC, and SIEM teams.
SIEM Knowledge - Highly Preferred
The candidate does not need to be a dedicated SIEM administrator, but should preferably understand:
·&nbsp;&nbsp; SIEM architecture and security-monitoring concepts.
·&nbsp;&nbsp; Telecom log-source onboarding and log collection/forwarding.
·&nbsp;&nbsp; Syslog and API-based integration concepts.
·&nbsp;&nbsp; Log parsing, normalization, validation, and security-event field mapping.
·&nbsp;&nbsp; Log-integration troubleshooting and data-quality validation.
·&nbsp;&nbsp; SIEM correlation, detection-use-case requirements, and SOC monitoring needs.
·&nbsp;&nbsp; Working knowledge of Splunk, Microsoft Sentinel, QRadar, FortiSIEM, or an equivalent SIEM platform.
Preferred OEM Experience
Ericsson&nbsp; |&nbsp; Nokia&nbsp; |&nbsp; Huawei&nbsp; |&nbsp; Cisco&nbsp; |&nbsp; Mavenir&nbsp; |&nbsp; Oracle
