The JiNao project at MCNC/NCSU focuses on detecting intrusions, especially insider attacks, against OSPF (Open Shortest Path First) routing protocol. This paper presents the implementation and experiments of the Ji-Nao's statistical intrusion detection module. Our implementation is based upon the algorithm developed in SRI's NIDES (Next-generation Intrusion(More)
DECIDUOUS is a security management framework for identifying the sources of network-based intrusions. The rst key concept in DECIDUOUS is dynamic security associations, which eciently and collectively provide location information for attack sources. DECIDUOUS is built on top of IETF's IPSEC/ISAKMP infrastructure, and it does not introduce any new network(More)
