SAFE-POS
SAFE-POS stands for "Security Assessment for False-Positive Elimination in Application Security." and reflects the objective of reducing false positives in application security assessments.
It highlights the need for accurate and reliable identification of genuine security issues while minimizing the occurrence of false positives, ensuring a more efficient and effective security assessment proces
In application security, the false positive rate refers to the percentage of security alerts or findings generated by security tools or assessments that are identified as potential vulnerabilities but are, in fact, benign or non-exploitable. A false positive occurs when a security tool or assessment mistakenly identifies an activity, behavior, or configuration as a security risk when it is not.
The false positive rate is an important metric in application security because it impacts the efficiency and effectiveness of security operations. Here are key aspects of the false positive rate in application security:
-
Identification of Non-Threatening Issues: False positives can arise from various sources, including vulnerability scanners, intrusion detection systems, static analysis tools, or manual security assessments. They may occur due to limitations in the tools' algorithms, misconfigurations, incomplete knowledge of the application's context, or the complexity of the security environment. It is essential to identify and differentiate false positives from genuine security risks to avoid wasting time and resources on non-threatening issues.
-
Impact on Security Operations: A high false positive rate can overwhelm security teams, leading to an inefficient allocation of resources. Security analysts spend valuable time investigating and validating false positives, diverting their attention from genuine security risks. It can also lead to alert fatigue and a decrease in the team's ability to respond effectively to real threats. Therefore, reducing the false positive rate is crucial for optimizing security operations.
-
Optimization of Security Controls: An excessive false positive rate can erode trust in security tools and processes. Organizations may be tempted to disable or ignore security alerts and findings due to the perceived high rate of false positives, which can result in a weakened security posture. By reducing false positives, organizations can ensure that security controls are properly tuned, enabling accurate identification and effective mitigation of genuine security risks.
-
Collaboration and Feedback: The false positive rate can be reduced through collaboration between security teams, application developers, and system administrators. By sharing insights, context, and feedback, false positives can be better understood and minimized. Continuous improvement and feedback loops help refine security tools, adjust security policies, and enhance detection capabilities, ultimately reducing the false positive rate.
-
Continuous Evaluation and Adjustment: To manage the false positive rate effectively, organizations should continuously evaluate and refine their security controls and processes. This includes tuning security tools, updating detection rules, enhancing threat intelligence, and adjusting security policies based on real-world experience and feedback. Regular assessment and adjustment of security measures help maintain an acceptable false positive rate while ensuring accurate identification of genuine security risks.
Aiming for a low false positive rate is crucial for maintaining the effectiveness and efficiency of application security efforts. It helps organizations focus resources on real security risks, minimize alert fatigue, and build confidence in the security infrastructure. Striking a balance between minimizing false positives and accurately identifying genuine threats is key to achieving an optimal level of application security.
SAFE-POS Metrics
False positive rate refers to the frequency or percentage of security alerts or findings that are incorrectly identified as positive or true indicators of a security vulnerability or issue, when in fact, they are benign or non-exploitable.
False positives occur when a security tool, such as a vulnerability scanner, intrusion detection system (IDS), or static code analyzer, generates an alert or flag based on a specific pattern or rule but incorrectly identifies it as a security vulnerability. This can result in an increased number of alerts or findings that security teams need to investigate and potentially waste resources on investigating and addressing non-existent issues.
A high false positive rate can have several implications for application security:
- Resource allocation: Security teams may spend significant time and effort investigating and remediating false positives, diverting resources from addressing genuine security issues that require attention.
Resource Allocation = (Total False Positives / Total Test Results) * 100.
-
The Resource Allocation metric measures the percentage of resources allocated for handling false positives in the context of application security. False positives are instances where a security tool or assessment identifies an issue as a vulnerability, but upon further investigation, it is determined to be a false alarm or not a genuine security risk. To calculate the Resource Allocation metric, divide the total number of false positives by the total number of test results and multiply the result by 100 to express it as a percentage.
-
For example, if during an application security assessment, there were 50 false positives identified out of a total of 500 test results, the Resource Allocation would be:
-
Resource Allocation = (50 / 500) * 100 = 10%
-
This means that 10% of the allocated resources are used to address and investigate false positives.
-
-
The Resource Allocation metric helps organizations understand the impact of false positives on their resource utilization in the application security process. It allows them to evaluate the efficiency of their testing and assessment procedures and allocate resources accordingly to minimize the impact of false positives.
-
By monitoring and optimizing the Resource Allocation metric, organizations can ensure that their resources are efficiently utilized and focused on addressing genuine security issues rather than false positives, leading to a more effective and streamlined application security program.
- Alert fatigue: A high false positive rate can lead to alert fatigue, where security professionals become overwhelmed by the sheer volume of alerts, causing them to miss or ignore genuine security threats.
Alert Fatigue = (Total False Positives / Total Alerts) * 100.
-
The Alert Fatigue metric measures the percentage of alert fatigue caused by false positives in the context of application security. Alert fatigue occurs when security personnel become overwhelmed or desensitized by a large number of alerts, many of which turn out to be false positives. To calculate the Alert Fatigue metric, divide the total number of false positives by the total number of alerts and multiply the result by 100 to express it as a percentage.
-
For example, if during a specific period, there were 200 false positives identified out of a total of 1000 alerts received, the Alert Fatigue would be:
-
Alert Fatigue = (200 / 1000) * 100 = 20%
-
This means that 20% of the alerts received were false positives, contributing to alert fatigue among the security personnel.
-
-
The Alert Fatigue metric helps organizations assess the impact of false positives on their security team's effectiveness and well-being. It provides insights into the proportion of alerts that are false positives, indicating the potential level of alert fatigue experienced by the security team.
-
By monitoring and reducing the Alert Fatigue metric, organizations can improve the efficiency of their incident response processes and reduce the risk of overlooking genuine security threats. This can be achieved through measures such as fine-tuning detection rules, implementing better filtering mechanisms, and investing in advanced threat intelligence tools to minimize false positives and alleviate alert fatigue.
- Efficiency and productivity: Dealing with a high number of false positives can slow down the incident response process, affecting the efficiency and productivity of the security team.
Efficiency and Productivity = (Total Validated True Positives / Total Alerts) * 100.
-
The Efficiency and Productivity metric measures the percentage of efficiency and productivity in the context of application security, taking into account the false positive rate. It quantifies the ratio of validated true positives to the total number of alerts received. To calculate the Efficiency and Productivity metric, divide the total number of validated true positives (i.e., confirmed genuine security issues) by the total number of alerts and multiply the result by 100 to express it as a percentage.
-
For example, if during a specific period, there were 80 validated true positives out of a total of 200 alerts received, the Efficiency and Productivity metric would be:
-
Efficiency and Productivity = (80 / 200) * 100 = 40%
-
This means that 40% of the alerts received were genuine security issues that required attention and action.
-
-
The Efficiency and Productivity metric helps organizations assess the effectiveness of their application security practices, specifically in terms of detecting and validating true positives amidst the noise of false positives. It provides insights into the ratio of genuine security issues identified from the total number of alerts received.
-
By monitoring and improving the Efficiency and Productivity metric, organizations can enhance the productivity of their security team, optimize resource allocation, and focus efforts on addressing genuine security threats. This can be achieved through the refinement of detection mechanisms, the implementation of more accurate alert triage processes, and the utilization of advanced threat intelligence to minimize false positives and maximize the identification of true positives.

-
The Customizing Rule Sets metric measures the effectiveness of customizing rule sets in reducing the false positive rate in application security. It quantifies the percentage of false positives that have been addressed by customizing rule sets. To calculate the Customizing Rule Sets metric, divide the number of false positives that have been addressed through custom rule set configurations by the total number of false positives identified and multiply the result by 100 to express it as a percentage.
-
For example, if there were 40 false positives that have been addressed through custom rule sets out of a total of 150 false positives identified, the Customizing Rule Sets metric would be:
-
Customizing Rule Sets Metric = (40 / 150) * 100 = 26.67%
-
This means that 26.67% of the false positives have been mitigated by customizing the rule sets specific to the application's context.
-
-
The Customizing Rule Sets metric highlights the importance of tailoring the rule sets to the specific requirements and characteristics of the applications being assessed. By customizing the rule sets, organizations can reduce false positives by refining the detection rules and aligning them with the unique behavior and functionality of their applications.
-
By monitoring and increasing the Customizing Rule Sets metric, organizations can continuously adapt and optimize the rule sets to minimize false positives and improve the overall accuracy of the application security system. This can be achieved through regular review and adjustment of rule configurations, leveraging contextual information, and maintaining an ongoing feedback loop with the security team and application owners.
- Regular validation and testing: Conducting regular validation and testing of security tools and methodologies to identify and address false positive issues promptly.
Regular Validation and Testing Metric = (Number of Regular Validations / Total False Positives) * 100.
-
The Regular Validation and Testing metric measures the extent to which regular validation and testing activities contribute to reducing the false positive rate in application security. It quantifies the percentage of false positives that have undergone regular validation processes. To calculate the Regular Validation and Testing metric, divide the number of false positives that have undergone regular validations and tests by the total number of false positives identified and multiply the result by 100 to express it as a percentage.
-
For example, if there were 50 false positives that have undergone regular validations out of a total of 200 false positives identified, the Regular Validation and Testing metric would be:
-
Regular Validation and Testing Metric = (50 / 200) * 100 = 25%
-
This means that 25% of the false positives have undergone regular validations and testing to assess their accuracy and reduce the false positive rate.
-
-
The Regular Validation and Testing metric reflects the importance of establishing a systematic approach to continuously validate and test the accuracy of the security systems. It highlights the commitment to ongoing quality assurance measures to identify and address false positives.

By monitoring and increasing the Regular Validation and Testing metric, organizations can ensure that false positives are regularly reviewed, validated, and refined to minimize their occurrence. This can be achieved through the implementation of rigorous validation processes, leveraging threat intelligence, employing advanced testing techniques, and maintaining up-to-date knowledge of application behavior and security requirements. Ultimately, this metric helps to improve the accuracy and reliability of application security systems while reducing false positive rates.
- Collaboration and feedback: Encouraging collaboration between security teams, developers, and tool vendors to provide feedback on false positives, improving the accuracy and effectiveness of security tools over time.
Collaboration and Feedback Metric = (Number of Collaborative Actions / Total False Positives) * 100.
-
The Collaboration and Feedback metric measures the effectiveness of collaboration and feedback processes in the context of reducing the false positive rate in application security. It quantifies the percentage of collaborative actions taken to address and improve false positives. To calculate the Collaboration and Feedback metric, divide the number of collaborative actions (such as discussions, investigations, and feedback exchanges) related to false positives by the total number of false positives and multiply the result by 100 to express it as a percentage.
-
For example, if there were 30 collaborative actions taken to analyze and provide feedback on false positives out of a total of 100 false positives identified, the Collaboration and Feedback metric would be:
-
Collaboration and Feedback Metric = (30 / 100) * 100 = 30%
