A large industrial energy operator experienced recurring reliability and cybersecurity concerns within its closed-circuit television (CCTV) network, which plays a critical role in physical security and operational awareness. The existing camera network had grown organically over time, resulting in architectural complexity, inconsistent configurations, and increased operational risk. Armexa was engaged to perform a comprehensive assessment of the CCTV network, document the existing environment, identify security and reliability risks, and provide actionable remediation and modernization recommendations. The engagement delivered clear visibility into the network, highlighted critical vulnerabilities and misconfigurations, and established a path toward a more resilient, secure, and maintainable CCTV infrastructure.
Problem
The organization’s CCTV network was experiencing intermittent connectivity issues, loss of camera feeds, and operational instability that complicated troubleshooting and reduced confidence in the system’s reliability. The network architecture consisted of a hybrid design that combined hub-and-spoke and ring topologies with inconsistent configurations, legacy hardware, and limited standardization across devices. Additionally, the environment contained numerous end-of-life or near–end-of-support network switches and firmware versions with known security vulnerabilities. These conditions increased the risk of unplanned outages, cybersecurity exposure, and long-term maintainability challenges, particularly as the camera system continued to expand.
Solution
Armexa conducted an onsite discovery and technical assessment of the CCTV network to establish a complete and accurate understanding of the environment. This effort included collecting and analyzing network device configurations, mapping physical and logical connectivity, and documenting the existing “as-is” architecture. The assessment identified routing inconsistencies, VLAN misconfigurations, unused and unsecured interfaces, and management network gaps that contributed to instability and security risk.
In parallel, Armexa performed a detailed hardware and firmware vulnerability review of the network switches supporting the CCTV system. This analysis evaluated lifecycle status, known software defects, and publicly disclosed security vulnerabilities, and aligned findings with vendor guidance. Based on these results, Armexa developed prioritized remediation actions and long-term recommendations, including configuration hardening, routing optimization, management network standardization, and a phased hardware and firmware lifecycle strategy.
Outcome / Benefits / Impact
The engagement provided the organization with a clear, authoritative view of its CCTV network and the factors contributing to reliability and security challenges. By documenting the existing environment and identifying specific configuration and lifecycle risks, Armexa enabled the client to move from reactive troubleshooting to informed, proactive decision-making. The recommended remediation actions reduced exposure to known vulnerabilities, improved network stability, and strengthened segmentation and access control. Long-term recommendations established a roadmap for modernization that supports operational resilience, simplifies expansion, and aligns the CCTV network with industrial cybersecurity and lifecycle best practices.
