Integrated Protection for
Nuclear Facilities:
Physical, Cyber and
Information Protection

INTEGRATION
The physical protection system of a nuclear
facility should be integrated and effective against
both sabotage and unauthorised removal
Appropriate physical protection measures should
be designed based on the more stringent
applicable requirements and implemented for
both in an integrated manner
INFCIRC/225/Rev.5, paragraphs 4.9 and 5.3

TARGET IDENTIFICATION AND
POTENTIAL CONSEQUENCES (2)
Sabotage of Nuclear and Other
Radioactive Material/Facilities
Define Unacceptable Radiological
Consequences (URC) using Graded
Approach
Determine whether Radioactive Inventory
has potential to result in URC
Identify material, equipment, systems and
devices
TARGET IDENTIFICATION AND
POTENTIAL CONSEQUENCES (3)
Unauthorised Access to Sensitive
Information/Cyber Attack
Sensitive Information – Classification Policy
Information and Communications Technology
(ICT) Systems/Instrument and Control (IC)
Systems –
Loss of Confidentiality, Integrity and Availability
Impact on Security and Safety Systems
VULNERABILITY ASSESSMENT (1)
Unauthorised Removal of Category I
Nuclear Material + Sabotage of High
Consequence Material/Systems –
Against DBT
VULNERABILITY ASSESSMENT (2)
Unauthorised Removal of other material +
Sabotage of other material/systems +
Compromise of Sensitive Information and
ICT/IC Systems Against DBT or
Threat Assessment
Physical Protection design Objectives
and/or Levels of Protection
Detect DBT
SECURITY PLAN
Integrated set of technical and
organisational measures
Utilising Defence in Depth
To protect against attack
Including predefined response actions
To effectively counter attempted
unauthorised removal or sabotage
INTEGRATED MEASURES
Physical measures – access control,
alarm monitoring etc
Security Culture – training and education
Personnel Security measures
Investigation of Security Events – impact
assessment
Sustainability – testing, change
management
Exercises
CONCLUSIONS
Physical Protection is a “Package”
Attackers exploit vulnerabilities
All Fundamental Principles in the CPPNM
apply equally to Information/Cyber
Security
