Period analysis algorithm.
Input: the alarm sequence generated by triple <Signature, srcIP, dstIP> | Output: alarm removal rule <Signature,srcIP,dstIP> | | (1) select an alarm sequence generated by a triple; | (2) determine the autocorrelation sequence ; | (3) while | (4) calculate the energy value of frequency ; | (5) endwhile | (6) calculate the frequency with the maximum energy; | (7) calculate the cycle of alarm sequence; | (8) calculate the value of F; | (9) if () | (10) generate the alarm removal rule <Signature,srcIP,dstIP>; | (11) Endif | |
