Projects

The Network Upgrade – Security Expansion Project, established a comprehensive security network for San Francisco’s primary wastewater treatment plant. With a budget of $770,000, the project focused on protecting critical infrastructure through a combination of advanced Network Access Control (NAC)802.1x, secure wireless, upgraded switching, servers, storage, physical security door control, and surveillance systems. NAC ensures policy is enforced to detect and authenticate devices at the point of connection.

This project is just one of three sites that received this level of upgrades. All video suveillance feeds are transmitted to centralized servers enabling continuous monitoring and improved situational awareness. The design ensures only authorized devices access the network, reducing the risk of intrusion and enhancing protection of critical assets.

The Digital Video Surveillance Conversion Project for the State of California Franchise Tax Board (FTB) involved upgrading and modernizing an extensive security camera system. All cameras an supporting infrastructure was upgaded to enhance an existing 200 analog and digital cameras to a unifed system. The original Bosch analog recording system was replaced with IP-based Milestone, and AXIS Communications technologies.

The project was complete with no system downtime. Multiport amplifiers were used to duplicate camera signals, allowing thorough testing and validation before the final cutover. Axis Communications encoders were used to convert all analog camera feeds into IP-based video, effectively modernizing the entire surveillance network.

The upgraded system added 80 terabytes of storage failover enabling higher frame rates for improved image quality. The project was recognized with a Gold Star rating by the State of California, highlighting NMC’s technical expertise and successful delivery.

The Sacramento Regional Water Treatment Plant “EchoWater” Project (Contract #4240) involved a major fiber optic infrastructure upgrade with project cost of $940,000. The project included designing new paths and deploying over 23,000 feet of new OM3 and OS1 shielded fiber optic backbone infrastructure. All cables were fusion spliced and certified.

Alternate routing had to be engineered to accomodate underground building structures. Over 9,000 feet of Galvanized and PGRS conduit was installed including explosion-proof passthroughs and mechanical seals to prevent chemical infiltration. Safety was critical due to the hazardous environment following OSHA standards and use of specialized detection equipment for confined or chemical-prone areas. The upgrades have improved the reliability, safety, and scalability of the plant’s network infrastructure.

An Austin-based company was targeted by a sophisticated cyber-fraud attack carried out by advanced persistent threat (APT) actors. Attackers used typosquatting to create a fraudulent email domain that closely resembled the company’s outsourced accounting firm. A key executive’s email account was compromise giving the actor insight into client financial communications. The actors created a fake invoice with a false embedded link redirecting payments to the attackers account.

Facing financial and reputational risk, I was engaged to conduct a detailed security breach analysis. I was able to identify the root causes; lack of multifactor authentication (MFA), delayed transfer of internal billing responsibilities, and reliance on manual processes. There were multiple contributing factors, including poor email verification practices and gaps in communication during billing handoffs.

A comprehensive remediation plan was delivered with key recommendations to improve employee awareness, phishing techiques, fraudulent domains, and strengthening communication protocols for invoicing.

By following NMC’s guidance, the company enhanced its cybersecurity posture, reduced future risk, and restored trust with its clients.
