Member States have developed regulations for the safety and security of nuclear material and facilities, as well as radioactive material and associated facilities, including inspection programmes for compliance. Due to the increasing computer security threats to the nuclear industry, computer security regulations also need to be developed and implemented, at the State level, in order to ensure the protection of nuclear information and operations and to maintain the integrity, availability and confidentiality of all nuclear and other radioactive materials, and associated facilities.This event will provide the relevant information on the international instruments and IAEA recommendations to enhance national regulators with a framework and regulations for computer security that can be integrated into their existing regulations.?The objective of the event is to present participants with the international instruments and IAEA recommendations for the drafting of computer security regulation of physical security, radioactive material, and material outside of regulatory control.
