As smart cities integrate previously separate infrastructure systems into a single network environment, the digital attack surface expands significantly. The sheer number of interconnected devices, many with inherent vulnerabilities, provides numerous entry points for malicious actors. Reports indicate that state and local governments require additional resources, shared intelligence, and coordination to effectively combat these threats.

Cyber resilience and incident response are crucial paradigms for navigating this complex cyber-physical landscape. While research in this area is active, empirical studies focusing on frameworks and systems that address cyber-physical systems (CPS) security in smart cities are still emerging. A systematic literature review highlighted that much of the existing research focuses on the "detection and analysis" phase of incident response, with limited attention paid to other critical stages like "response," "recovery," and "prevention". Furthermore, areas like "forensics" and "cyber resilience" also require further investigation.

One of the most prominent threats facing smart cities is ransomware. Municipalities are increasingly in the crosshairs of "Ransomware as a Service" (RaaS), which makes encryption malware more accessible. The cyberattack against the city of Atlanta serves as a stark reminder of the potential for significant disruption and economic impact from such attacks.

Cybersecurity encompasses processes, standards, technology, and education, requiring a layered approach that combines people, processes, and technology for effective defense.
• Risk Assessment and Vulnerability Management: A crucial first step is recognizing vulnerability through comprehensive risk assessments across all departments to identify potential risks and security gaps. Understanding network and system vulnerabilities is essential for developing effective defenses.
• Policies and Procedures: Developing written cybersecurity policies and procedures for all employees and ensuring their adoption is vital for managing human and technical weaknesses. These policies should address acceptable use, access management, and the increasing use of personal mobile devices for work.
• Incident Response Planning: Preparing for cyberattacks is no longer optional. Local governments must develop comprehensive written incident response plans to restore critical systems and networks quickly. These plans should outline procedures for identifying, investigating, and responding to incidents, drawing on resources like the NIST framework.
• Secure Design and Implementation: Smart city infrastructure should be designed with security in mind from the outset, including secure hardware and software, strong encryption, and secure coding practices. Applying the principle of least privilege and enforcing multifactor authentication are crucial security measures.
• Network Segmentation: Dividing the smart city network into smaller segments can limit the damage caused by a cyberattack, preventing a breach in one area from compromising the entire system.
• Supply Chain Risk Management: Proactively managing ICT supply chain risks, using trusted vendors, and setting security requirements for software and hardware suppliers are essential to prevent exploitation of vulnerabilities.
