The proliferation of the Internet of Things (IoT) has led to an unprecedented level of interconnectedness, embedding computational capabilities into everyday objects. While this paradigm shift offers significant advancements in efficiency and automation across various sectors, it concurrently introduces complex security vulnerabilities. Critical infrastructures, such as power grids, water supply systems, and transportation networks, are increasingly integrating IoT devices for monitoring and control. This integration, however, creates new attack vectors that could be exploited by malicious actors, potentially leading to catastrophic failures. The challenge lies in the inherent heterogeneity of IoT devices, many of which lack robust, built-in security features and are difficult to patch or update, a reality often referred to as 'cyber-physical convergence risk'.

Considering the context of cybersecurity within IoT-enabled critical infrastructures, which of the following statements most accurately analyzes a primary vulnerability?

Alternativa A:
The primary vulnerability stems from the over-reliance on cloud-based data processing, which centralizes points of failure and makes them susceptible to Distributed Denial of Service (DDoS) attacks.
Alternativa B:
The most significant security risk is the lack of standardized communication protocols, which allows for man-in-the-middle attacks by enabling attackers to easily intercept and manipulate unencrypted data streams between devices.
Alternativa C:
A fundamental vulnerability lies in the widespread use of default or weak credentials in IoT devices, coupled with the inability to enforce strong password policies or conduct regular updates, creating an easily exploitable entry point for network infiltration.
Alternativa D:
The main issue is the physical insecurity of the devices themselves, as attackers can easily gain physical access to tamper with them, overriding any software-based security measures.
Alternativa E:
The core vulnerability is rooted in the computational limitations of most IoT devices, which prevents the implementation of sophisticated encryption algorithms, thereby rendering all transmitted data insecure by design.
