Internal Network Security • Penetration Testing • ISO Readiness
A banking institution managing critical financial data and customer transactions required an internal security audit to assess the strength of its IT infrastructure. The goal was to identify security gaps, outdated systems, and operational risks while improving the overall security maturity of both infrastructure and staff handling sensitive banking operations.
The bank’s IT infrastructure had grown over time, but security reviews were not conducted regularly. Some systems were running outdated operating systems and services, increasing the risk of exploitation. Additionally, while employees handled sensitive banking data daily, there was limited clarity on security best practices, threat awareness, and attack patterns, creating a gap between technology and human security.
The bank wanted a hands-on internal security audit to identify weaknesses in their systems, network, and services. They were concerned about outdated software, unknown vulnerabilities, and the ability of their IT team to respond to real-world threats. Along with this, the management also wanted their banking staff and IT team to gain practical security awareness, so risks could be reduced at both technical and human levels.
Worked with bank management and IT teams to understand the internal network, core banking systems, user access flow, and define the audit scope.
Reviewed: Network architecture and internal access controls, Server and endpoint configurations, Authentication mechanisms and service exposure
Identified systems running: Outdated operating systems, Legacy and unsupported services, Missing security patches and updates
Detected issues such as: Unpatched vulnerabilities, Weak service configurations, Exposure of internal services that could be abused
Performed controlled testing to: Simulate real-world attack scenarios, Validate how easily vulnerabilities could be exploited, Assess internal movement risks within the bank network
Worked directly with the bank’s IT team to: Explain findings in a practical way, Assist in patching and securing systems, Validate fixes and confirm risk reduction
Conducted focused training sessions for: Banking staff - awareness on phishing, data handling, and common threats, IT team - understanding attack paths, vulnerabilities, and response basics
