Which measure should be taken to regularly harden kiosks against new threats?

Onboarding the kiosks to Azure Monitor is a crucial measure for regularly hardening kiosks against new threats because it provides continuous monitoring and real-time insights into the security status of the devices. By integrating Azure Monitor, you gain access to advanced analytics and actionable intelligence that can help detect anomalies, unauthorized access attempts, and other potential security issues. This kind of proactive monitoring is essential for identifying emerging vulnerabilities or attacks, ensuring timely responses, and maintaining the overall security posture of the kiosks.

In contrast, while establishing a hardware firewall, implementing Azure Defender, and deploying additional security hardware can contribute to a stronger security setup, they may not offer the same level of continuous visibility and real-time threat detection as Azure Monitor. These measures can enhance security but may not be sufficient for ongoing adaptation and responsiveness to new and evolving threats that are often identified through effective monitoring solutions. Regular hardening requires not just protective measures but also a way to adapt defenses based on the latest threat intelligence, which is precisely what Azure Monitor facilitates.
