Can you describe more about the input data for Rapidminer clustering? How many dimension does a data point have? Did you apply any pre-processing method for input data? Thank you for the question. Regarding the system overview diagram [slide no.6], we obtained 38 parameters from the MobSF analysis report. We then classified them into six data groups [slide no.9]. After that, we performed data cleansing for each data group before inputting the data into RapidMiner. We checked for missing data values, incorrect data formats, and transformed Boolean or status values into numbers, such as "0" for "no/false" and "1" for "yes/true". Subsequently, we calculated the centroid table using RapidMiner for each data group, ranging from 2 clusters to 6 clusters. Finally, we manually calculated the elbow curve to determine the optimal number of clusters.

Regarding the static analysis approach of assessing application security, can you elaborate on how the source code, manifest.xml, and security features are evaluated for potential vulnerabilities? Thank you for the question. The source code analysis steps, the tool will scan for code pattern for common security flaws such as data input validation, insecure data handeling, SQLinjection, using raw SQLcommand execution. The tool will shows the locations of potential vulnerabilities and suggesting remediation actions. The manifest.xml analysis will checking for sensitive permissions requested by the app and requests excessive or unnecessary permissions, which could potentially lead to security and privacy risks. Last, security features will examine how security features are implemented and also check whether these features are implemented correctly according to security best practices and guidelines. So these analysis steps can help to identify and address potential vulnerabilities and fix problems early in the development process making the app more secure overall.
