A financial institution recognized that basic defensive measures were insufficient in an increasingly sophisticated cybersecurity threat landscape. The client needed to proactively identify exploitable vulnerabilities across both its internal network environment — housing sensitive customer and financial data — and its internet-facing systems, which represent the primary external attack surface.
The engagement objective was to simulate real-world attack scenarios, identify critical vulnerabilities before malicious actors could exploit them, and produce a prioritized remediation roadmap aligned with FFIEC Cybersecurity Assessment Tool requirements and GLBA safeguards obligations.
Finoptics executed a comprehensive two-phase methodology. The Internal Vulnerability Assessment (IVA) used a gray-box approach, employing vulnerability scanning tools (Nessus) across specified IP ranges to detect insecure services, weak configurations, and outdated software that could be exploited by an insider or attacker who gains initial access.
Simultaneously, an External Vulnerability Assessment (EVA) and penetration test were conducted using a black-box approach — utilizing only publicly available information, as an external attacker would. This included scanning public IP addresses with Qualys VMDR, performing manual penetration testing, and conducting open-source intelligence (OSINT) gathering to identify exposed administrative portals and sensitive access points. Cross-referencing internal and external findings enabled prioritization of chained vulnerabilities that represent the highest actual risk.
The testing produced a comprehensive risk map with measurable, in-depth insights into the institution's security posture. Critical findings included unencrypted SNMP and Telnet services on the internal network, TLS vulnerabilities and unnecessarily open service ports externally, and publicly accessible administrative pages representing a direct threat vector for unauthorized access.
A prioritized remediation plan was delivered, addressing unused service disablement, encryption implementation, system patching, and access control hardening. The institution addressed immediate vulnerabilities and established a proactive, continuous process for managing cybersecurity risk — significantly improving its defensive posture and FFIEC examination readiness.
