The Client
The client is a prominent mobile network operator located in Northern Europe, responsible for providing comprehensive telecommunications services to millions of subscribers.
Facing increasing complexity and regulatory pressure, the client engaged Ethon Shield to conduct a thorough OSS security audit to proactively address potential threats.
We conducted a comprehensive review of the client’s OSS infrastructure, including server security, automation scripts, data protection protocols, and system integrity safeguards.
Scale of Infrastructure:
The client operated a vast network with thousands of servers, making it essential to audit a representative sample.
Complexity of Configuration:
The diverse configurations and varying security measures across different servers added complexity to the audit process.
Legacy Systems:
Legacy systems posed unpatched vulnerabilities, opening the door to privilege escalation and insider threats.
Ethon Shield conducted a comprehensive security assessment tailored to the unique needs of the client’s OSS infrastructure. The services included:
Comprehensive Security Audit: We assessed all OSS servers to validate best practices across SSH, root privileges, and network connectivity, ensuring hardened configurations and consistent enforcement.
Vulnerability Assessment: We uncovered misconfigured components and unpatched software in legacy systems, closing vulnerabilities that could have enabled lateral movement or exploit chaining.
Access Control Review: We ensured that only authorized personnel retained access to sensitive data, enforcing least privilege and reducing insider risk.
