....attacks and violations easily codi ed into security policies in a timely and ecient manner. Problems include a diculty in detecting previously unknown intrusions. If a database containing intrusion signatures is employed it must be updated frequently. Early in the research it was suggested in [6, 12] that the two main methods ought to be combined to provide a complete intrusion detection system capable of detecting a wide array of di erent computer security violations, including the ones listed above. At present, the many fundamental questions regarding intrusion detection remain largely ....

....the third person masculine pronoun, since the overwhelming majority of computer criminals (as is true of most other criminals in society) belong to that gender. 4 of the idea to process audit data for manifestations of already known intrusive behaviour. About the same time it was suggested [19, 40] that the two complimentary approaches of seeking anomalous activity based on some historic data, and searching for signatures of already known intrusions, should be employed in the same intrusion detection system, to better complement the relative strengths and weaknesses of the two approaches. ....
....approaches of seeking anomalous activity based on some historic data, and searching for signatures of already known intrusions, should be employed in the same intrusion detection system, to better complement the relative strengths and weaknesses of the two approaches. One of the papers ([19]) also suggested that this system be autonomous enough to be trusted to respond unsupervised to detected intrusions. Although the author of that paper recognised that much research was yet to be done before this goal could be attained. In summary: early research concerned itself with the question ....

About the same time it was suggested in [HK88, Lun88] that the two main methods ought to be combined to provide a complete intrusion detection system, and that the resulting system should be made autonomous enough to be trusted to respond to detected intrusions unsupervised.
