The explosion of connected devices is widening the attack surface

The Internet of Things (IoT) has fundamentally changed how cities operate. Current estimates place the number of connected IoT devices at approximately 18 billion globally, with projections suggesting this figure will exceed 40 billion by 2030. From smart traffic systems and water management sensors to connected healthcare devices, these technologies bring tremendous efficiency gains but also create massive security challenges.

The problem is straightforward: every connected device represents a potential entry point for attackers. According to Verizon’s Data Breach Investigations Report, one in three data breaches now involves an IoT device. This correlation between device proliferation and cyberattack frequency is no coincidence. IoT devices often ship with minimal security hardening, default passwords, and limited update capabilities.

Why IoT security remains challenging

Most IoT devices prioritize cost and functionality over security. Research indicates that approximately 98% of IoT device traffic remains unencrypted, meaning sensitive operational data travels across networks in plain text, completely exposed to interception. Furthermore, many organizations lack visibility into exactly what devices connect to their networks, creating dangerous blind spots that attackers readily exploit.

The consequences extend beyond data theft. Smart city infrastructure increasingly relies on connected systems for critical functions. Compromised devices can disrupt water treatment facilities, traffic management systems, or healthcare equipment, creating real-world safety implications that go far beyond financial losses.

Ransomware attacks are becoming more targeted and destructive

Ransomware has evolved from opportunistic attacks into a sophisticated criminal enterprise. Total ransomware payments reached approximately $813 million in 2024, though this represents a decrease from the record $1.25 billion paid in 2023. This decline, however, does not indicate a reduction in attacks. Instead, it reflects improved victim resilience and increased law enforcement pressure.

Cryptocurrency remains the payment method of choice for ransomware operators because it enables pseudonymous transactions that are difficult to trace. The Ransomware-as-a-Service model has lowered barriers to entry, allowing less technically sophisticated criminals to launch devastating attacks using pre-built tools and infrastructure provided by established criminal organizations.

The shift toward double and triple extortion

Modern ransomware operators no longer simply encrypt files and demand payment. Triple extortion tactics have become increasingly common, where attackers encrypt data, steal sensitive information, and then threaten to publish it publicly if demands are not met. This approach puts additional pressure on victims, particularly healthcare organizations, government agencies, and educational institutions that handle sensitive personal data.

Smart city infrastructure presents particularly attractive targets because the interconnected nature of urban systems means a single successful attack can cascade across multiple services, maximizing disruption and increasing the likelihood of payment.

Cloud services face persistent misconfiguration vulnerabilities

Organizations across all sectors have embraced cloud computing for its flexibility, scalability, and cost efficiency. However, this rapid adoption has outpaced security practices. Research from SentinelOne found that nearly 23% of cloud security incidents stem from misconfigurations, making human error rather than sophisticated hacking the primary vulnerability.

The problem lies in the shared responsibility model that governs cloud security. Cloud providers secure the underlying infrastructure, but customers remain responsible for properly configuring their environments. Gartner projects that through 2025, over 99% of cloud breaches will result from preventable misconfigurations rather than flaws in the cloud platforms themselves.

Common misconfiguration pitfalls

Exposed storage buckets, overly permissive access controls, and inadequate encryption settings create pathways for unauthorized access. Tenable’s Cloud Security Risk Report reveals that 9% of publicly accessible cloud storage contains sensitive data, exposing organizations to compliance violations, intellectual property theft, and customer data breaches.

For smart city deployments, where municipal data, citizen information, and operational systems increasingly reside in cloud environments, these vulnerabilities pose serious risks. A misconfigured cloud instance could expose traffic patterns, utility usage data, or even emergency response system credentials.

Legacy systems create persistent security gaps

Many organizations, particularly in the public sector, continue operating outdated IT infrastructure that was never designed with modern security threats in mind. These legacy systems often cannot receive security patches because vendors no longer support them, yet they remain connected to networks that interface with modern applications and the internet.

The challenge is particularly acute in smart city contexts where new connected technologies must integrate with existing infrastructure. Water treatment facilities, power grids, and transportation systems often rely on industrial control systems that may be decades old. Forescout’s research indicates that routers account for over 50% of the most critically vulnerable systems in organizational networks, with many running outdated firmware that contains known security flaws.

Attackers specifically target these weaknesses because exploiting documented vulnerabilities in unpatched systems requires minimal effort compared to discovering new attack vectors. The result is a persistent and growing security gap that threatens the stability of critical infrastructure.

Remote work has permanently expanded organizational attack surfaces

The pandemic-era shift to remote work created lasting changes in how organizations operate, but many security frameworks have not fully adapted. According to survey data from the Information Systems Security Association, 65% of cybersecurity professionals report their jobs have become harder over the past two years, with remote work security ranking among their primary challenges.

Home networks lack the security controls present in corporate environments. Personal devices used for work often run outdated software, connect through consumer-grade routers with default configurations, and share networks with potentially compromised personal devices. Each of these factors creates opportunities for attackers to establish initial access that can then be leveraged to move deeper into organizational systems.

The blurred security perimeter

Traditional security models assumed that protecting network boundaries would safeguard organizational assets. Remote work has essentially dissolved these boundaries. Employees working from home or co-working spaces experience threats from weak passwords, poor credential storage, and unsecured devices in public spaces. The result is an attack surface that security teams struggle to monitor and protect.

For smart city administrators, this reality means that employees accessing municipal systems remotely could inadvertently provide attackers with pathways into critical urban infrastructure.

Multi-factor authentication remains a critical defensive layer

Despite known limitations, multi-factor authentication continues to represent one of the most effective defenses against unauthorized access. Microsoft reports that over 99.9% of compromised accounts lack MFA protection, demonstrating how significantly this single control reduces breach risk.

The MFA market has grown substantially, reflecting increasing adoption across organizations. Current market valuations place MFA at approximately $20.9 billion, with projections suggesting growth to $70 billion by 2033. This expansion indicates that organizations increasingly recognize authentication as a fundamental security requirement rather than an optional enhancement.

Moving beyond SMS-based authentication

Security experts increasingly advocate for app-based authenticators over SMS verification. Threat actors have developed techniques like Adversary-in-the-Middle attacks specifically designed to bypass MFA, making phishing-resistant methods such as hardware tokens and biometric verification increasingly important. Organizations deploying smart city systems should prioritize these stronger authentication methods, particularly for administrative access to critical infrastructure.

Data privacy concerns are reshaping how organizations handle information

Growing awareness of data privacy has driven both regulatory expansion and changing consumer expectations. According to PwC’s Voice of the Consumer Survey, 83% of respondents now consider data protection a top priority when evaluating brand trustworthiness. This shift has significant implications for smart city initiatives that often involve collecting and processing large volumes of citizen data.

Regulatory frameworks continue expanding globally. The International Association of Privacy Professionals reports that approximately 82% of the global population is now protected under national data privacy laws, with 144 countries having enacted such legislation. In the United States, the absence of comprehensive federal privacy legislation has led to a patchwork of state laws, with over 20 states now enforcing their own privacy requirements.

High-profile data breaches have amplified public concern, creating pressure for organizations to demonstrate robust data protection practices. For smart city planners, this means privacy considerations must be integrated into system design from the outset rather than addressed as afterthoughts.

What do you think? As smart cities become increasingly dependent on interconnected technologies, how should urban planners balance the benefits of connectivity against these growing security risks? And what role should citizens play in demanding stronger cybersecurity protections for the public systems that handle their data?
