In the cybersecurity echo chamber, the relentless assault of false positives on Security Operations Center (SOC) teams is surpassed only by the cacophony of vendor marketing fluff claiming to reduce them. It's like listening to a symphony played on broken instruments. You know you're more likely to get that two or five percent reduction by turning off an existing tool than adding a new one.

False positive rates in existing tools are awful. Yet, we've accepted their inevitability to the point where we measure them to compare how good a tool is versus how bad it is. "Sucks-less" may be inevitable in political decisions, but it doesn't have to be with security tools. Deterministic detection of security incidents exists with the potential to silence the noise of those broken instruments and reveal attack signatures too faint to break through.

This blog explores the transformative potential of deterministic authorization across the three states of digital data, at rest, in transit, and in use, to eliminate false positives in incident detection.

The False Positive Quandary and Deterministic Solutions

Data-at-Rest: A Model of Determinism

The foundation of data security, data-at-rest, showcases the efficacy of deterministic access controls such as Access Control Lists (ACLs). These controls set the stage for explicit, enforceable permissions that significantly mitigate the risk of false positives, demonstrating the untapped potential of deterministic methods in broader cybersecurity contexts.

Data-in-Transit: Bridging the Gaps

When data transitions into motion, it encounters a landscape where deterministic authorization becomes challenging yet increasingly necessary. The lack of embedded permissions in data packets underscores a critical vulnerability in confidentiality, despite existing measures for integrity and availability. This gap highlights the urgent need for integrating permissions within data protocols to ensure comprehensive and deterministic security measures.

Data-in-Use: The Final Frontier

Arguably the most complex state to secure, data-in-use demands a nuanced approach to deterministic incident detection. The proliferation of microservices and cloud-based architectures has obscured the clear linkage between user identities and data permissions, necessitating innovative solutions to restore determinism in authorization practices within these distributed environments.

Towards a Deterministic Future: Strategies and Solutions

The journey to a more deterministic cybersecurity framework requires a multifaceted strategy. It begins with embedding permissions directly within data transactions and extends to reevaluating our architectural approaches to cloud applications. By drawing inspiration from initiatives like Caber's CA/CO, and filling in the gaps exposed by Google's BeyondProd, and enterprise Digital Rights Management we can chart a path towards achieving deterministic authorization across all states of digital data.

Conclusion: A Call to Action for SOCs

The embrace of deterministic incident detection signals a pivotal moment in cybersecurity. By adopting a deterministic approach, SOCs can dramatically reduce false positives, focusing their efforts on genuine threats and enhancing overall operational efficiency. This blog has outlined the critical steps and considerations necessary for this transformation, highlighting the indispensable role of innovative solutions and collaborative industry efforts. As we move forward, the call to action is clear: the time for SOCs to pivot towards a deterministic and more secure future is now.
