Review Questions

• How does insider threat analysis contribute to an organization's overall security posture?
  • Insider threat analysis enhances an organization's security posture by proactively identifying vulnerabilities associated with individuals who have internal access. By assessing behaviors and potential motivations of employees, organizations can implement preventive measures tailored to reduce risks. This not only helps in thwarting possible attacks but also fosters a culture of vigilance among employees, making them more aware of their roles in maintaining security.
