The Psychology of Insider Threats: Neurological Predictors of Malicious Behaviour

Insider threat has been identified as one of the most complicated cybersecurity issues, with 76% of organizations finding an increment in insider threats than five years ago, yet, less than 30 percent feel they are prepared with the proper tools to deal with it. According to recent data, organizations are losing an average of $17.4M in insider threats with credential theft having an average cost of $779K single event. Contrary to the outside attackers, who would have to break through the guarding perimeter, insider threats originate inside the accepted scope of the organization and thus prove to be extremely hard to monitor and predict. With the field of neuroscience advancing our knowledge of human behaviour and decision-making, scientists are undertaking research on how neurological patterns can be used to tell who may pose a risk of an insider threat in the future, well before they turn malicious.

The Neuroscience of Betrayal and Deception

Recently, neuroimaging experiments have also started probing the patterns of the brain when making moral judgments, although the latter is of great controversy in deception detection application. A review of functional magnetic resonance imaging (fMRI) studies has explored brain activity in moral dilemmas, including results that show the neural involvement of the anterior cingulate cortex and the prefrontal regions implicating cognitive control. Nevertheless, there are still some scientific limitations to fMRI-based deception-detecting because, according to some study, it is only better than chance, but not that much perfect. The difficulty is that the extent of difference between laboratory results and field use is quite broad. Although neuroimaging can objectively detect those brain areas that are active in the context of an experimental deception task, researchers remark that it is not possible to find a neural location or circuit devoted to lying that is sensitive, specific, generalizable across individuals and measurement circumstances, and resistant to countermeasures. Neuroscience today is not yet in a position to reliably distinguish between honest and deceptive answers to the accuracy necessary to apply to consequential security contexts. Based on these results, it can be assumed that there may be some correlations regarding specific neurological patterns with a higher level of proneness towards the insider threat. Nevertheless, there is a complex and rather personal connection between brain activation maps and real malicious actions.

Psychological Risk Factors and Neural Correlates

The traditional research on the insider threat outlined a number of psychological risks: financial pressure, job dissatisfaction, a sense of injustice, and personal crises. There are newly developed neuroscience studies that are now mapping the way these psychological states become brain operations. One of the most common precursors of insider threats, chronic stress, is associated with quantifiable alterations in brain structure and performance. Chronic exposure to cortisol influences the prefrontal cortex and the hippocampus, which play an essential role in decision-making and impulsion-ness. This neurobiological stress reaction may adversely affect decision making and present a predisposition to poor ethical decisions. The medial prefrontal cortex during self-referential thought process and the temporoparietal junction exhibit less activation on empathy related processes with individuals who have the tendency towards narcissism. These tendencies may lead to justification of the wrong acts to the organization.

Current Detection Approaches and Limitations

The vast majority of modern insider threat detection is based on behavioural analytics, the tracks of digital activity, accesses, and metadata of communication. Although, to a certain extent, effective, these methods are also reactive and usually detect the threat after some of the suspicious activity has occurred. The potential of integrating neurological evaluation into insider threat programs comes with intriguing possibilities and very serious questions. Supporters believe that further research into the neural roots of lying and moral judgment may be able to initiate more forthcoming risk evaluation. A similar example can be seen in cases where certain neural indicators are consistently present prior to manifesting the insider threat behaviour and such could be accepted at the screening protocols of high-security job roles. Nevertheless, the existing technology of neuroscience has significant weakness. Brain imaging is laborious and expensive, and laboratory conditions are not ideal in screening at the workplace. In addition, the links between neural activity and real-world behaviours are probabilistic, not necessarily deterministic.

Ethical Considerations and Privacy Concerns

Detecting an insider threat using neuroscience presents serious ethical challenges. Brain activity is perhaps the ultimate source of human secret, and surveillance of neural patterns at a security level is a step into unknown grounds as far as privacy and human rights are concerned.

Major ethical issues are:

• Cognitive liberty: The right to mental autonomy and neural surveillance free self-determination employs a basic human right that numerous ethicists declare needs to be defended.

• Predictive Accuracy: We do not have any powerful predictive accuracy that can be used as accurate future behavior in neuroscience to take significant actions with regard to security matters. False positives would end careers and lives one based on flawed neural data.

• Informed Consent: The neuroscience is intricate to allow pure consent especially in instances where employment can be denied based on the lack of participation in meaningful neural screening regimes.

• Discrimination Risk: Neurological differences may turn out to be used as the instrument of discrimination in the workplace especially against people who have mental disorders or were found to be neurologically diverse.

  
  

A Framework for Ethical Research

Nevertheless, there is otherwise justified research interest to learn the neurological origin of insider threats. Going by a responsible research framework, it might contain:

• Post-Incident Analysis: Researching on the neural patterns of those who have already been determined as an insider threats but with their permission to detail the neurobiology of behaviour but not in any practical predictive use.

• Voluntary Participation: The conduct of any neurological assessment should be purely voluntary and there should be no employment implications to declining partake.

• Anonymized Data: To further the scientific knowledge but with no individual risk profile, conducting research on de-identified data is possible.

• Longitudinal Studies: Tracking people over time to be able to see how their brain patters correlate with life events, stress levels, and behavior change whilst ensuring high privacy protection.

  
  

Future Directions and Practical Applications

The most viable applications in the near-term would be not in direct neural screening per se but rather guided organizational psychology. This knowledge about the interaction of stress with the workplace culture and individual differences on the neuronal level would promote the design of more effective insider threat prevention efforts. Neuroscience-informed solutions offered to organizations may include workplace wellness and stress management programs and ethical culture development. Companies do not need to filter out any potential threats, but should ensure that the environment encourages healthy functioning in their nervous system and sound moral judgement.

Conclusion

Neuroscience has shown fascinating explainers of the psychology of insider threats, but the sphere is not near to practical application in security screening. Human behaviour is not that simple, the current technology is not also sufficient, and there are also moral issues that cannot allow direct neural assessment to be used in workplace security. Nevertheless, insights about effective prevention of an insider threat can be developed on the basis of the ethical neuroscience studies in question, working more comprehensively on organizational culture, stress-related conditions, and the psychological predilection to malicious actions. The aim must not be to predict and prevent instances of malfeasance by brain monitoring but to design environments in which ethical action is both neurologically and psychologically primed.
