A Voice Firewall Can Protect Employees From Vishing Attacks

In light of the recent MGM Resorts International data breach, it's critical to consider how advanced technical controls, like the Mutare Voice Traffic Filter, and the application of the FAIR (Factor Analysis of Information Risk) ontology could have potentially mitigated the risks.

The Mutare Voice Traffic Filter offers a robust defense against telephone fraud by filtering out harmful calls before they reach employees. This system utilizes a multi-layered approach, integrating STIR/SHAKEN protocols, meta-analysis in tracking malicious numbers globally, and AI-driven threat radar.

In the case of MGM Resorts, the breach involved unauthorized access to customer personal information by a telephone vishing attack vector. While post-breach measures were taken, including system shutdowns and offering credit monitoring to affected customers, the lack of a preventative voice firewall like Mutare's might have left a gap for scammers to exploit, leading to the breach.

Incorporating the FAIR ontology into MGM’s risk management strategy could have further enhanced their defenses. FAIR provides a quantitative model for understanding, analyzing, and quantifying cyber and operational risks in financial terms. This method differs from traditional qualitative assessments, offering a more concrete foundation for managing information risk.

Improving resistance strength and reducing contact frequency are crucial elements in this approach. By quantifying these factors, organizations can better assess and mitigate the potential impact of cyber threats. Using FAIR’s methodology, which includes a standard taxonomy and ontology for risk, along with frameworks for data collection and risk factor measurement, could have provided MGM with a more robust and scalable model for analyzing and mitigating complex risk scenarios.

In summary, the combination of employing a voice traffic filter like Mutare’s and applying the FAIR risk quantification model could significantly enhance an organization's ability to preemptively tackle cybersecurity threats, thereby preventing incidents like the MGM breach.
