ISO/IEC/ITU-T Strategic Advisory Group on Security

• Outgrowth of ISO Advisory Group on Security (2004)

• Expanded to ISO+IEC+ITU-T in 2005• First meeting: April 2005• Initiative of the World Standards

Collaboration

Terms of Reference• To oversee standardization activities

in ISO, IEC and ITU-T relevant to the field of security

• To provide advice and guidance to the ISO Technical Management Board, the IEC Standardization Management Board and the ITU-T Telecommunication Standardization Advisory Group (TSAG) relative to the co-ordination of work relevant to security, and in particular to identify areas where new standardization initiatives may be warranted.

• To monitor the implementation of the recommendations of the Advisory Group on Security

ICT is an embedded infrastructure within a larger system. Security requires sound overall system architecture and an integrated

approach encompassing both ICT and physical system security

Example: The Smart Grid

Observations

• Overall system security requires sound overall architecture

• Interactions between ICT and physical systems must be considered

• Security requires co-development of standards for both the physical application and embedded ICT infrastructures

• Standards are typically done by different communities

• New forms of collaboration within and among SDOs is needed
