An Extensive Comparison of Static Application Security Testing Tools: Evaluating SASTTs Accuracy and Coverage

Kernkonzepte

Enhancing Recall over Precision is crucial for improving SASTTs effectiveness in vulnerability identification.

Zusammenfassung

The study evaluates Static Application Security Testing Tools (SASTTs) to set a benchmark for assessing their effectiveness. Findings reveal low Recall but high Precision in SASTTs, with false negatives outnumbering false positives. Multiple SASTTs and alternative techniques like machine learning should complement each other for comprehensive vulnerability identification. Recommendations include using weighted averages, trusting empirical results over documentation claims, and focusing on reducing false negatives in vulnerability detection.

Statistiken

Our findings reveal that SASTTs detect a tiny range of vulnerabilities.
Our study shows that SASTTs excel in Precision while falling short in Recall.
The total number of non-unique ECWEs across our eight SASTTs is 146.
Most CWEs are expected but not actually identified by any SASTT.
A single SASTT covers a maximum of 12 ACWEs, i.e., 11% of JTS.

Zitate

"We shall trust SASTTs performances in empirical results rather than in documentation."
"Multiple SASTTs and other techniques should complement each other for comprehensive vulnerability identification."

How can the industry address the issue of low Recall in current SASTTs?

One way to address the issue of low Recall in current Static Application Security Testing Tools (SASTTs) is by implementing a multi-tool approach. By using multiple SASTTs in combination, organizations can increase their chances of identifying vulnerabilities that may be missed by a single tool. This approach leverages the strengths of different tools and helps mitigate the limitations of individual tools, ultimately improving overall vulnerability detection rates.
Another strategy is to focus on enhancing the capabilities of existing SASTTs through continuous improvement and innovation. This could involve refining algorithms, incorporating more advanced analysis techniques, expanding test coverage, and optimizing detection mechanisms to reduce false negatives. Additionally, providing regular updates and patches for SASTTs can help ensure they stay effective against evolving threats.
Furthermore, investing in training programs for developers and security professionals on how to effectively use SASTTs can also contribute to improving Recall rates. By increasing awareness and knowledge about best practices in vulnerability identification and remediation, organizations can enhance their overall security posture.

What are the implications of relying on a single SASTT for vulnerability identification?

Relying solely on a single Static Application Security Testing Tool (SASTT) for vulnerability identification poses several implications and risks for organizations:

Limited Coverage: A single SASTT may not be able to detect all types of vulnerabilities present in an application due to its specific scanning algorithms or limitations. This could result in undetected vulnerabilities that pose security risks.

False Sense of Security: Depending on one tool may give a false sense of security as it might miss critical vulnerabilities that another tool could have identified. Organizations may overlook potential threats assuming that their chosen tool has provided comprehensive coverage.

Lack of Diversification: Using only one tool limits diversification in vulnerability identification approaches. Different tools have varying strengths and weaknesses; leveraging multiple tools provides a more holistic view of an application's security posture.

Inadequate Response Capability: If a single SASTT fails to identify certain vulnerabilities or produces false positives/negatives, organizations may struggle with responding effectively to emerging threats or remediating issues promptly.

To mitigate these implications, it is advisable for organizations to adopt a multi-tool approach or supplement traditional testing methods with other forms of security testing like dynamic analysis or penetration testing.

How can advancements in machine learning impact the effectiveness of current vulnerability identification solutions?

Advancements in machine learning have significant potential to enhance the effectiveness of current vulnerability identification solutions:

Improved Accuracy: Machine learning algorithms can analyze vast amounts of data quickly and accurately, enabling them to detect patterns indicative
of vulnerabilities that might be missed by traditional methods like rule-based systems used by most static analysis tools.

2.Enhanced Automation: Machine learning models can automate various aspects
of vulnerability detection processes such as feature extraction,
anomaly detection,and pattern recognition.This automation reduces manual effort,time,and resources required for identifying vulnerabilities.
3.Adaptability & Scalability: Machine learning models are capable
