Automated detection of vulnerabilities and weaknesses in binary code is a critical need at the frontier of cybersecurity research. Cybersecurity static-analysis tools aim to detect and enumerate vulnerabilities and weaknesses. Two popular tools are CVE Binary Tool (cve-bin-tool) and cwechecker. Cve-bin-tool reports vulnerabilities using Common Vulnerabilities and Exposures (CVE) whereas cwe-checker reports weaknesses using Common Weakness Enumeration (CWE). Despite widespread use, the consistency with which these tools report vulnerabilities and weaknesses (herein, “findings”) was unaddressed. We conducted a systematic investigation of 660 unique binaries taken from a Kali Linux distribution, evaluated each binary with multiple versions of the static-analysis tools, and investigated how the findings changed according to the version of the static-analysis tool used. We expected some variation in findings commensurate with the software-development life cycle. However, we were surprised by the number and magnitude of the changes in findings reported across versions. New versions gave new answers.more » « less

Instrument fidelity in message testing research hinges upon how precisely messages operationalize treatment conditions. However, numerous message testing studies have unmitigated threats to validity and reliability because no established procedures exist to guide construction of message treatments. Their construction typically occurs in a black box, resulting in suspect inferential conclusions about treatment effects. Because a mixed methods approach is needed to enhance instrument fidelity in message testing research, this article contributes to the field of mixed methods research by presenting an integrated multistage procedure for constructing precise message treatments using an exploratory sequential mixed methods design. This work harnesses the power of integration through crossover analysis to improve instrument fidelity in message testing research through the use of natural language processing (NLP).more » « less

null (Ed.)Context: Managing technical debt (TD) associated with external cybersecurity attacks on an organization can significantly improve decisions made when prioritizing which security weaknesses require attention. Whilst source code vulnerabilities can be found using static analysis techniques, malicious external attacks expose the vulnerabilities of a system at runtime and can sometimes remain hidden for long periods of time. By mapping malicious attack tactics to the consequences of weaknesses (i.e. exploitable source code vulnerabilities) we can begin to understand and prioritize the refactoring of the source code vulnerabilities that cause the greatest amount of technical debt on a system. Goal: To establish an approach that maps common external attack tactics to system weaknesses. The consequences of a weakness associated with a specific attack technique can then be used to determine the technical debt principal of said violation; which can be measured in terms of loss of business rather than source code maintenance. Method: We present a position study that uses Jaccard similarity scoring to examine how 11 malicious attack tactics can relate to Common Weakness Enumerations (CWEs). Results: We conduct a study to simulate attacks, and generate dependency graphs between external attacks and the technical consequences associated with CWEs. Conclusion: The mapping of cyber security attacks to weaknesses allows operational staff (SecDevOps) to focus on deploying appropriate countermeasures and allows developers to focus on refactoring the vulnerabilities with the greatest potential for technical debt.more » « less

Context: Managing technical debt (TD) associated with potential security breaches found during design can lead to catching vulnerabilities (i.e., exploitable weaknesses) earlier in the software lifecycle; thus, anticipating TD principal and interest that can have decidedly negative impacts on businesses. Goal: To establish an approach to help assess TD associated with security weaknesses by leveraging the Common Weakness Enumeration (CWE) and its scoring mechanism, the Common Weakness Scoring System (CWSS). Method: We present a position study with a five-step approach employing the Quamoco quality model to operationalize the scoring of architectural CWEs. Results: We use static analysis to detect design level CWEs, calculate their CWSS scores, and provide a relative ranking of weaknesses that help practitioners identify the highest risks in an organization with a potential to impact TD. Conclusion: CWSS is a community agreed upon method that should be leveraged to help inform the ranking of security related TD items.more » « less
