In a recent interview, Federico Charosky, CEO of Quorum Cyber, highlights the importance of understanding the nuances of insider risk in cybersecurity. He emphasizes the need to differentiate between malicious and inadvertent insider threats, as this distinction is crucial in addressing the nature of the problem and finding appropriate solutions.

Charosky refers to the Microsoft Digital Breach report, which reveals that approximately 85% of attacks involve an insider component. This highlights the significant role insiders play in enabling successful cyberattacks, whether intentionally or unknowingly.

Identity compromise is a key factor in the success of cyberattacks. Charosky advocates for deconstructing the term ‘insider risk’ to better manage its various components and allocate resources effectively. Oversimplifying insider risks leads to ineffective strategic approaches.

It is important to differentiate between ‘insider risk’ and ‘insider threat’. While the former signifies a potential vulnerability, the latter implies malicious intent. Understanding this distinction helps in developing appropriate defensive or responsive tactics.

The question of whether phishing attacks should be categorized as insider risks is raised by Charosky. While the interpretation may vary, the focus should be on implementing anti-phishing measures alongside other security measures to combat insider threats effectively.

Charosky emphasizes the need for a layered defense strategy, rather than relying solely on employee awareness and action. A multi-faceted approach, aligned with the ‘defense in depth’ principle, ensures comprehensive protection across various organizational layers.
