Threat and vulnerability assessments are systematic evaluations conducted to identify and analyze potential threats and vulnerabilities that could impact the security, safety, or integrity of an organization, facility, or system. These assessments are essential for understanding risks and implementing effective security measures to mitigate them. Overall, threat and vulnerability assessments are essential components of the risk management process, providing organizations with valuable insights into potential risks and vulnerabilities and guiding the development of proactive security measures to protect against them. These assessments are iterative processes that require ongoing monitoring and adaptation to address evolving threats and changes in the security environment.

Components of the assessments:


  • Threat Assessment: Definition of threats, Evaluation of threat likelihood and impact, Scenario analysis, and External and internal threats.
