The Nuanced Landscape of Insider Threats: A Conversation with Federico Charosky of Quorum Cyber


In a recent interview, Federico Charosky, CEO of Quorum Cyber, shed light on some often-underappreciated yet crucial facets of insider risk in cybersecurity. Charosky emphasizes the necessity of nuanced definitions when discussing the topic of insider risk. He argues that the term frequently gets misinterpreted and misused, and organizations must discriminate between malicious and inadvertent insider threats. This distinction is not a semantic subtlety; it is fundamental to understanding the nature of the problem and its corresponding solutions. Malicious insiders act with harmful intent, while inadvertent insiders serve as unwitting vectors manipulated by external adversaries.

The Internal-External Threat Dichotomy

Adding a layer of complexity to insider risks, Charosky refers to the Microsoft Digital Breach report, which states that approximately 85% of attacks, irrespective of the assailant’s motives, involve an insider component. This data highlights the near-universal role of insiders in enabling a successful attack, whether knowingly or unwittingly.

The Role of Insider Identity

Identity compromise is pivotal in the success of cyberattacks. The attack chain frequently encompasses some form of identity manipulation, be it through coercion, deception, or the unsuspecting insider being maneuvered into facilitating the attack. This is why Charosky advocates for deconstructing the term ‘insider risk’ to better manage its various components, thereby allowing an organization to efficiently allocate its resources and tackle the most pressing vulnerabilities first. Oversimplifying insider risks into a monolithic issue leads to flawed strategic approaches.

Distinguishing ‘Insider Risk’ from ‘Insider Threat’

It is crucial to differentiate between ‘insider risk’ and ‘insider threat,’ terms often used interchangeably. While an insider risk signifies a potential vulnerability (e.g., an employee with excessive access permissions), an insider threat implies an individual taking malicious actions.

The Phishing Conundrum

Charosky also raised the question of whether phishing attacks should be categorized as insider risks. While the taxonomy may be open to interpretation, what’s important is how this understanding informs defensive or responsive tactics. The threat of phishing is tangible and represents just one avenue through which a legitimate identity can be exploited for malicious ends. Therefore, anti-phishing measures like secure email gateways and awareness training are indispensable but should not be viewed as a panacea for combating insider threats.

The Imperative for a Layered Defense

Charosky’s ultimate message is a call for a layered defense strategy. Sole reliance on employee awareness and action is a failing proposition. The onus should not be solely on insiders to fortify an organization’s cybersecurity. This philosophy aligns with the ‘defense in depth’ principle, advocating for a multi-faceted array of security measures to safeguard various organizational layers.

Insider risk is a multi-dimensional challenge requiring a nuanced understanding and a sophisticated strategy for mitigation. Federico Charosky’s insights serve as an urgent reminder that reducing the complexity of the issue is counterproductive. Whether aligning IAM protocols, adopting Zero Trust security models, or emphasizing the critical role of ongoing training and awareness programs, a comprehensive, multi-layered approach is indispensable for effectively mitigating insider risks.
