The intrusion detection based on model checking temporal logic is effective in detecting the complicated and variable network attacks. However, certain types of attacks remain undetected due to the lack of formal models. To solve this problem, a linear temporal logic is employed to model the variable patterns of Udpstorm attacks. First, an analysis of the principles of Udpstorm attacks is given and...
Compared with other methods, intrusion detection approaches based on temporal logics can deal with many complicated network attacks effectively. Mail bomb attacks, however, are unable to be detected by the above methods due to the lack of formalization models. Thus, we use Time Interval Temporal Logic (TITL) to create a model for this type of attacks. At first, the attack principle is analyzed, and...
Interval temporal logic (ITL) model checking reduces the false negative rate of misuse detection for concurrent attacks. However, no ITL formula can be used to describe the time constraints between various actions in the same attack. To this end, we use a timed interval temporal logic (TITL) formula to describe such constraints as well as the absolute time of atomic steps in an attack. On this basis,...
