WAID: wavelet analysis intrusion detection

Current approaches to intrusion detection have been demonstrated to be relatively effective in identifying network attacks that occur sequentially from a single source. Those that are distributed over an extended period of time are particularly difficult for current intrusion detection approaches to detect. Numerous forms of network attacks can be temporally dispersed. Those that deny authorized users access to system resources can often be most effectively conducted by distributing them through time. Wavelet analysis intrusion detection (WAID) is achieved by treating state-realizable protocols as discrete waveforms. WAID is offered as a multidimensional analysis approach to detecting temporally-spaced network attacks. Several applications are discussed along with a theoretical basis.
