  • Conduct threat hunting and IOC correlation to detect stealthy attacks across telecom infrastructure.
  • Analyze malware and conduct memory and disk forensics using tools such as Volatility, FTK, EnCase, and Autopsy.
  • Stay current on threats to the telecom sector including APT groups, signaling layer exploits, and SS7 / Diameter vulnerabilities.
  • Support regulatory compliance (e.g., NCA, TRA, GDPR, SAMA) and law enforcement requests by providing forensic evidence and incident reports.
  • Organize and lead tabletop exercises and breach simulations involving telecom-specific threat scenarios.

  • Strong understanding of network security, TCP / IP, firewalls, proxies, and telecom-specific attack surfaces.
  • Hands-on experience with SIEM tools (Splunk, QRadar), EDR platforms (CrowdStrike, SentinelOne, Cortex XDR), and forensic tools.
  • Proficiency in Python, Bash, or PowerShell scripting for automation and custom parsing.
  • Solid grasp of MITRE ATT&CK, NIST 800-61, ISO / IEC 27035, and telecom security best practices.
