Thus, an intrusion detection algorithm based on ASDL is obtained. The case studies and simulations show that the new method can find coordinated chop-chop attacks. Compared with the anomaly ID methods, the misuse ID ones cannot report unknown types of attacks. However, the latter methods have a comparatively low false positives rate with regard to known types of attacks.
This is due to the principle of misuse intrusion detection: The system will monitor the audit log. Once a data stream in the log is found to match with certain attack type, it means that an attack is found. However, such a class of detection methods based on pattern matching PM suffers from their inherent problems, such as the lack of power of detecting various changing attack patterns [ 1 ], [ 2 ]. To address these issues, a series of intrusion detection methods based on model checking [ 3 ] have been developed in [ 1 ], [ 2 ] and [ 4 ].
Their basic principle can be formulated as follows: The logical constructs in temporal formulas can flexibly describe various logical relationships between attack actions. Compared with the PM-based approaches, the MC-based ones can effectively portray the ever-changing attack patterns [ 1 ], [ 4 ].فيديو: WEP korek chopchop attack
Furthermore, the MC-based approaches have an important advantage for intrusion detection over the PM-based ones. Pattern matching is usually applicable to detect inconsistencies between data while automata, temporal logic formulas and model checking techniques are applicable to detect inconsistencies of behaviors.
Thus, the MC-based methods can do something more than the PM-based ones since intrusion attacks involve complex behaviors besides the comparatively simple data [ 5 ]. Linear temporal logic LTL and interval temporal logic ITL are employed to describe network attacks, respectively in [ 1 ], [ 2 ] and [ 6 ]. However, these logics cannot describe a large number of complex repeated attacks and coordinated attacks, due to their insufficient expressive ability.
In particular, a coordinated attack usually consists of multiple attacks on the same target. It is usually launched by multiple attackers under a unified strategy. A coordinated attack consists of many dispersed behaviors. And none of them is believed to be a danger by IDS algorithms.
