The Network and Distributed System Security Symposium, better known as NDSS, is one of the leading academic venues for security research. NDSS Symposium 2027 brings together researchers and practitioners who design, implement and deploy network and distributed system security technologies, with a particular emphasis on practical work that can be put into real-world use. The 2027 edition moves to Seoul, South Korea, running from 22 to 26 March at the Grand InterContinental Seoul Parnas. Hosting the symposium in Asia makes this security research conference in Seoul in 2027 more accessible to the region's universities, laboratories and industry research teams. The five-day schedule reflects the symposium's academic structure, in which peer-reviewed papers form the core of the programme. Attendees gain direct access to new research findings, often before they are widely discussed elsewhere, along with the opportunity to question authors and debate methods in person. The event also serves as a meeting ground between academia and industry, helping ideas move from papers into deployable systems. For the global security research community, NDSS remains a key venue where rigorous, practical work on securing networks and distributed systems is presented, scrutinised and carried forward.
NDSS Symposium 2027 takes place March 22–26, 2027 in Seoul, South Korea.
NDSS Symposium 2027 is an in-person event.

NDSS runs from 22 to 26 March at the Grand InterContinental Seoul Parnas, a hotel joined to the COEX convention and shopping complex in Gangnam's Samseong neighbourhood. This is Seoul's corporate and exhibition quarter rather than its palace district, so the area around the venue is glassy, busy and full of food courts. Late March sits right before the cherry blossom peak; early varieties sometimes flower by the final day, and the evenings stay cool enough to need a jacket.
Incheon International Airport (ICN) is the main long-haul gateway, around 60 km west. Airport limousine buses run to the COEX area in roughly 70 to 90 minutes depending on traffic, while the AREX train to Seoul Station plus a subway transfer takes a similar time. Gimpo Airport (GMP), used for regional flights, is closer at about 45 minutes. Samseong subway station connects directly to COEX underground.
Skip the taxi queue — pre-book a fixed-price airport transfer with Kiwitaxi. Exploring beyond the city? compare rental cars on EconomyBookings.

Korea has excellent, fast mobile coverage and free Wi-Fi in most subway stations. An eSIM with a local data plan makes navigation apps and ride-hailing far simpler from the moment you land. Set up an eSIM with Airalo before you board and you're online the moment you land.
Bongeunsa Temple. A Buddhist temple founded over a thousand years ago, sitting directly across the road from COEX with a large standing Maitreya statue surrounded by towers. Its contrast with the skyscrapers is striking. Visit at dusk for the lanterns, or in the early morning for quiet; forty-five minutes is plenty, and entry is free.
Starfield Library. An open, multi-storey library built into the COEX Mall, with wall-high shelves holding tens of thousands of books and magazines. It is free and a five-minute walk from the conference halls, so it suits a short break between sessions. Weekday mornings are calmer than weekends, when it fills with visitors taking photos.
Seonjeongneung Royal Tombs. Burial mounds of Joseon-dynasty kings set in a wooded park near Seolleung station, part of a UNESCO World Heritage listing. Paths loop through pine trees and grassy slopes, offering one of the quietest green spaces in Gangnam. Allow an hour; it is one subway stop from Samseong or a pleasant twenty-minute walk.
Lotte World Tower Seoul Sky. The observation decks near the top of this supertall tower in Jamsil, a short subway ride east, give a full panorama of the Han River and surrounding mountains. A glass-floored section adds a thrill. Go late afternoon to watch the city lights come on, and allow about ninety minutes including queues. Tickets on Klook →
Do I need a K-ETA or visa?
Requirements depend on nationality and have changed in recent years, so check Korea's official K-ETA website well before travelling.
How should I pay for transport?
A rechargeable T-money card works on subways, buses and many taxis, and is sold at convenience stores. Some foreign contactless cards also work on transit gates.
What will the weather be like?
Expect roughly 4 to 14°C, with dry, cool days. Fine dust occasionally reduces air quality in spring, so check a local forecast.
