Describe, with the aid of a diagram, how a Bayesian classifier based system for detecting malware on an Android platform works [7 marks] (b) Table 1 shows the frequency of code-based properties of 1000 samples of malware and normal Android application code respectively. From the table calculate the following probability values for the feature getNetworkOperator: P(Ri=1), P(Ri=0), P(C=MRi=1), P(C=M|Ri=0), P(C=B|Ri=1) and P(C-B|Ri=0) [4 marks] [Please turn over] Page 5 of 6 CSC3059/1718 Malware Frequency Benign Frequency Code Properties getSubscriberID getSimSerialNumber DexClassLoader createSubprocess jar (secondary payload) KeySpec (code encryption) getNetworkOperator Chown 742 42 455 35 16 152 169 C 252 254 87 99 353 202 107 5 Table 1: Code-based properties and their frequency of occurrence in 1000 samples.
