Analyzing the Perceived Severity of Cybersecurity Threats Reported on Social Media
Table 12: Top ranked log-odds ratio of subjective adjectives describing severe threats (CVSS scores ≥ 7.0) versus non-severe threats (CVSS scores < 7.0). Subjective adjectives are identified by using Subjectivity Lexicon (SUB) Wilson et al. (2005).
['Adj. serious', 'Ratio 2.01', 'Adj. aware', 'Ratio 1.61', 'Adj. fast', 'Ratio 1.39']
We examine subjective adjectives people use for measuring threats. We run POS tagging to extract all tokens marked as JJ, JJP, and JJS. We then rank subjective adjectives in Subjectivity Lexicon (SUB) Wilson et al. We observe variants people are using for severe threats, e.g. “serious”, “severe”, “malicious”, etc.
