Sharing the Latest
Security Knowledge
at the NDSS Symposium

To keep the Internet robust and resilient, we need more research and collaboration into its security issues.

The Network and Distributed System Security (NDSS) Symposium is an international academic security conference focused on the latest in network and distributed system security.

The Internet Society has been hosting and organizing the Symposium for over 30 years, growing it to be one of the world’s premier security conferences, attracting participants worldwide. It brings together academic, industry, and security practitioners worldwide to share knowledge and discuss top-tier, peer-reviewed research.

The NDSS Symposium, which was originally called the Workshop on Network and Distributed System Security, was first held on 11-12 February, 1993 in San Diego, California. It was organized as workshop of the Privacy and Security Research Group of the Internet Research Task Force and hosted by the Internet Society and Lawrence Livermore National Laboratory.

Addressing Lack of Trust in the Internet

Through the collaborative sharing of top-tier research on systems security, the NDSS Symposium helps the Internet and research community:

  • Identify and mitigate potential new security attacks and vulnerabilities.
  • Develop and publish new security technologies, which can potentially be standardized in an open and accessible manner.
  • Nurture the next generation of Internet security researchers and practitioners who can embark on their careers with a strong network of collaborators.
