BCS Exam CISMP-V9 Topic 9 Question 100 Discussion

The deployment of end-to-end Internet of Things (IoT) solutions significantly increases the attack surface compared to traditional IT systems. This is due to the vast number of connected devices, each potentially introducing new vulnerabilities. The heterogeneity of these devices, often with varying levels of security, can lead to more entry points for cyberattacks. Additionally, the complexity of managing and securing these numerous devices, especially when they use different communication protocols and standards, exacerbates the risk. Therefore, the expansion of the attack surface is considered the greatest risk because it amplifies the potential for unauthorized access and compromises the integrity, availability, and confidentiality of information systems.
