Developing a proactive insider risk management strategy

CISOs should adopt various strategies to manage and mitigate insider threats effectively:

  • Foster a risk-aware culture — Regular training and awareness programs can educate employees on the importance of cybersecurity and their role in preventing security incidents.
  • Implement the principle of least privilege — Limit access to sensitive information and systems to only those who absolutely require it for their role.
  • Monitor user behavior — Use user and entity behavior analytics (UEBA) tools to identify anomalies in employee and device activity, allowing for early detection and response to suspicious activity.
  • Encourage reporting of suspicious activity — Establish clear channels for employees to report unusual behavior without fear of retribution.
  • Conduct regular audits and assessments — Periodic reviews of user access rights and system configurations can help identify areas of potential risk and ensure security controls are working as intended.

Reinstating trust in the organization through communication and collaboration

Effective communication and collaboration are essential for mitigating insider threats. By focusing on communication, fostering a culture of shared responsibility, and creating an environment of mutual confidence, organizations can better manage insider risks. This includes promoting a culture of risk awareness, collaborating with peers to improve incident response, and establishing a baseline for user behavior.

A modern, collaborative security operations function integrates teams and departments, such as HR, Legal, and Security, to address insider risks. Cross-departmental communication and cooperation help detect and respond to potential incidents, minimizing the overall impact of insider threats.

A transparent charter defines roles and responsibilities for stakeholders involved in managing insider risks. This fosters shared responsibility among employees, enhances prevention, and augments detection. The charter should clearly delineate the roles of key stakeholders in managing insider threats.

A cohesive multi-year plan should include regular touchpoints for senior leaders and tangible assets, such as intelligence reports and year-end summaries. This continuous improvement plan ensures that organizations stay up-to-date with the latest insider threat trends and respond effectively to new challenges.


Insider threats are a complex and ever-evolving challenge that requires a multifaceted, proactive approach to mitigate risks effectively. By implementing these strategies and fostering a risk-aware culture, organizations can significantly reduce the likelihood of insider incidents and safeguard their valuable assets.
