Terminology (1): Standards The Common Criteria for Information Technology Security Evaluation (CC) is the driving force for the widest available mutual recognition of secure IT products. This web portal is available to support the information on the status of the CCRA, the CC and the certification schemes, licensed laboratories, certified products and related information, news and events.Common Criteria for Information Technology Security Evaluation (CC) The ISO series of standards have been specifically reserved by ISO for information security matters. This of course, aligns with a number of other topics, including ISO 9000 (quality management) and ISO (environmental management).ISO series Security SIG in MTS, 4-5 October

Next steps Contributions in MTS Start Special Interest Group (SIG) for “security [testing]” First meeting 15 th December 2011 in Berlin: NWI TS focusing on security testing terminology (methodology etc.)? Similar to ongoing performance testing work NWI TR focusing on security including industrial case studies? Similar to ETSI TR (Application of Model-Based Testing in the Telecoms Domain) Collaboration with INT new work item on Security/Benchmarking test plan (using MSF inputs) Collaboration with TISPAN TVRA lacks on test methods Enrichment with (model-based) testing techniques? Latest news: TC TISPAN final meeting planned for February 2012, new group planned 10 Security SIG in MTS, 4-5 October 2011, updated 15 December 2011

More Steps & Perspectives Contribution to new ETSI Industrial Specification Group (ISG) on Information Security Indicators (ISI) Transfer to other international committees (e.g. ISO)  using PAS (public available specification) criteria to  initiate further international NWI (e.g. via DIN) ETSI members support: FOKUS, Conformiq, TestingTech, Codenomicon, FSCOM, … 11 Security SIG in MTS, 4-5 October 2011
