The Network Security Lab (NSL) at Columbia University's Computer Science
Department is dedicated to performing cutting-edge research in critical
areas of network and systems security. This research includes new
methods for efficient encryption, system and network reliability,
autonomic security, reactive security systems, automated patching,
host-based intrusion prevention, applications of peer-to-peer networks,
security and availability policy, and network intrusion detection and
anomaly analysis.
The Intrusion Detection Systems (IDS) group at Columbia University aims to
build next-generation tools to detect stealthy and malicious intruders in
computer systems. This includes research into anomaly detection, collaborative
intrusion detection, attacker modeling, malicious code, and secure wireless
networks. Headed by Professor Salvatore J. Stolfo, IDS includes 6 PhD students
and a number of masters and undergraduate students. Several IDS technologies
from our lab have been successfully commercialized and deployed in protecting
network infrastructure.
The Network Computing Laboratory (NCL) pursues research in experimental
software systems to make personalized computing ubiquitously available,
anytime and anywhere. Our research areas include operating systems, system
resource management, interactive web and multimedia systems, utility
computing, thin-client computing, mobility, and performance evaluation.
The Distributed Network Analysis Research Group comprises of faculty and
students from both the Department of Computer Science and the Department of
Electrical Engineering at Columbia. Our group's facilities reside in both the
COMET Lab in EE and the SOS Lab in CS. The current research emphasis is the
design and analytical evaluation of techniques used to ensure that emerging
network systems are secure and robust to a variety of anomalous (extreme)
network conditions.
The Internet Real-Time Lab (IRT) in the Computer Science Department at
Columbia University conducts research in the areas of Internet and multimedia
services: Internet telephony, wireless and mobile networks, streaming, quality
of service, resource reservation, dynamic pricing for the Internet, network
measurement and reliability, service location, network security, media on
demand, content distribution networks, multicast networks and ubiquitous and
context-aware computing and communication.
