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.

For 30 years, the symposium has brought together academic and industry researchers and security practitioners worldwide to share knowledge and discuss top-tier, peer-reviewed research.

The Symposium has grown into one of the world’s premier security conferences, attracting participants worldwide.

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. The Internet Society has proudly hosted the NDSS Symposium since.

Defending the Internet 

Through the collaborative sharing of leading research on systems security, the NDSS Symposium helps the Internet community make the Internet more secure:

  • Potential new security attacks and vulnerabilities can be identified, mitigated, and shared in an open and accessible manner. 
  • New security technologies can be developed, published, and potentially standardized in an open and accessible manner
  • The next generation of Internet security researchers and practitioners can embark on their careers with a strong network of collaborators.  
  • Academic, industry, and standards communities can better understand the emerging security problems and solutions and will be better positioned to work together to solve them.
