Examining Cybersecurity Vulnerabilities and Countermeasures to Combat the Insider Threat in Radiological Security February 2020 Authored by: Jaime Wise, PMP Brandon Gorton, PSP CISSP Michael Hazel Brian Higgins, PMP PNL XXX XXX
Topic objective Explore the challenges posed by the cyber vulnerabilities present in a cloud-hosted architecture and propose a strategy to mitigate targeted risks 2
ORS Background Office of Radiological Security (ORS) is a voluntary program within the U.S. Department of Energy, National Nuclear Security Administration Our mission is to collaborate with partner countries throughout the world to enhance the security of radioactive sources used for legitimate purposes Additional information at: www.orsportal.org 3
State of the Industry Digital communications Access control Video surveillance Intrusion detection Alarm communications Rapidly expanding capabilities System integration Feature enhancements Global connectivity 4
Identifying a Modern Approach Traditional physical security concepts Defense in depth Detection, delay, and response Evolving into a modern approach Information Security Triad Principle of least privilege Awareness of attack surface Cyber hygiene 5
Sentry Remote Monitoring System The Sentry Remote Monitoring System (Sentry-RMS) is a networked detection and assessment system The intent is to: Provide insider threat mitigation Add additional layer of asset security System capabilities: Radiation detection Tamper indication Auxiliary alarm inputs and outputs Redundant alarm communications 6
Sentry-RMS Communications and Response Platform Sentry-RMS Communications and Response (Sentry- SECURE) Platform stakeholder diagram 7
Sentry-RMS Communications and Response Platform Sentry-RMS Communications and Response (Sentry- SECURE) Platform component diagram 8
Additional ORS Tools Continued importance of a balanced approach to enhancing the physical protection system Hardware and software Policies and procedures Training 9
Enduring Challenges Dynamic nature of cyber domain Significance of the insider threat Enhancing Success in Radiological Security Defense in depth using varied administrative, physical, and technical security controls Success requires a cyclical, not linear approach 10
Conclusion Sustainable security in cyber-physical domain necessitates Time - continued commitment Saturation consistent but diverse messaging Innovation though implementing a multidisciplinary, multidomain approach 11
