Welcome to the 40th IFIP TC-11 SEC 2025 International Information Security and Privacy Conference Web Site. The SEC conferences are a series of well-established international conferences on Security and Privacy. SEC is the flagship event of the International Federation for Information Processing (IFIP) Technical Committee 11 (TC-11, www.ifiptc11.org).

Maribor was chosen as on of European best destinations to visit in autumn.

The IFIP SEC conferences aim to bring together primarily researchers, but also practitioners from academia, industry and governmental institutions to elaborate and discuss IT Security and Privacy Challenges that we are facing today and will be facing in the future.

We seek submissions from academia, industry, and government presenting novel research on all theoretical and practical aspects of security and privacy protection in ICT Systems.
