Modernizing municipal IT infrastructure: A vital defense against cyber threats

This summer, Flint, Mich., became the latest in a growing list of U.S. municipalities to fall victim to a ransomware attack. This incident, which took city services offline for weeks, is a stark reminder of the vulnerabilities many local governments face in an increasingly hostile cyber landscape. The attack on Flint underscores the urgent need for municipalities across the country to modernize their IT infrastructure to defend against sophisticated cyber threats. My last company, Nexient, was based in Ann Arbor, Mich., so when the news broke about this, it really caught my attention. 

On August 14, 2024, Flint city officials discovered that a ransomware attack had compromised their IT systems. The attackers encrypted critical data, rendering many of the city’s essential services inoperable. This included the city’s online payment systems for water and sewer services, internal communication networks and other administrative functions crucial to day-to-day operations.

The impact on Flint’s residents was immediate. Unable to access online payment portals, many were left in the dark about how to manage their utility bills. City employees struggled to carry out their responsibilities without access to essential data and systems. The attack caused operational chaos and raised concerns about the potential exposure of sensitive personal information.

Challenges in recovery
Flint’s recovery process was slow. City officials, working alongside cybersecurity experts and law enforcement, were able to restore some services by the end of August, but the road to full recovery was long. The city had to rebuild much of its IT infrastructure from the ground up, installing next-generation firewalls and implementing enhanced security protocols to prevent a recurrence of such an attack.

The cost of recovery, both in terms of financial resources and public trust, was substantial. Flint’s experience highlights the significant challenges municipalities face in recovering from a major cyber incident, particularly when their IT infrastructure is outdated and ill-equipped to handle modern cyber threats.

Why do municipalities hesitate?
Despite the clear and present dangers posed by outdated systems, many municipalities resist modernizing their IT infrastructure for several reasons:
