Detecting a Root Cause for a Vulnerability Using Subjective Logic in Social Media

A computing device comprising:

• a processor;
• a network interface coupled to the processor to enable communication over a network;
• a storage device coupled to the processor;
• a vulnerability engine code stored in the storage device, wherein an execution of the code by the processor configures the computing device to perform acts comprising:
• monitoring social media communication;
• identifying social media threads that are related to a vulnerability of a computing device, based on the monitored social media communication;
• filtering the identified social media threads by removing SPAM postings therefrom;
• categorizing the filtered identified social media threads into one or more predetermined categories of computing device vulnerabilities;
• upon determining that a number of social media posts of the social media threads related to the vulnerability is above a first predetermined threshold:
• searching one or more dependable social media threads in a same one or more categories of the vulnerability;
• determining one or more possible root causes of the vulnerability from the searched dependable social media threads;
• assigning a validity score for each of the one or more possible root causes;
• and
• selecting a possible root cause from the one or more possible root causes that has a highest validity score that is above a second predetermined threshold, to be the root cause of the vulnerability.
