This white paper explores the significance of snippet identification in achieving open source license compliance and maintaining robust software security. Open source software has revolutionized modern development practices but also introduced challenges related to compliance with open source licenses. Acknowledging and complying with license obligations requires accurately identifying whole components and snippets of code copied from open source projects. While identifying whole components is relatively straightforward, identifying snippets poses a more complex task. This paper highlights the critical role of advanced software composition analysis (SCA) tools in facilitating snippet identification. It examines how snippet identification supports open source legal compliance, effective software security management, proper management of AI-generated source code, and maintaining a transparent and collaborative approach with the open source community.


Open source software has become an integral part of modern software development, offering numerous benefits in terms of cost, flexibility, and innovation. However, using open source components and integrating open source software with commercial products and services bring along certain responsibilities, primarily centered around compliance with open source licenses.

Open source license compliance refers to adhering to the terms and conditions set forth by open source licenses when using, distributing, or modifying open source software components. It involves ensuring that organizations comply with the licensing obligations, such as providing proper attribution, sharing modifications, and distributing the corresponding source code when required (these obligations differ depending on the open source license). Open source compliance aims to support the legal and ethical use of open source software while respecting the rights of the original authors and contributors. It typically involves identifying open source components and snippets integrated into the software stack, tracking their licenses and obligations, and implementing appropriate policies and procedures to ensure license compliance throughout the software development and distribution lifecycle. By achieving open source license compliance, organizations can mitigate legal risks, foster transparency, and contribute to the collaborative nature of the open source community.

One crucial aspect of license compliance is the identification of snippets copied from open source software and incorporated into other software components, be it proprietary, third-party software, or other open source software components. Failure to identify and properly acknowledge these snippets can lead to non-compliance cases, legal disputes, and reputational damage.

SCA Tools: Enabling the Automation of Open Source Compliance

With the help of software composition analysis (SCA) tools, software development teams can track and analyze any open source code brought into a project from a licensing compliance and security vulnerabilities perspective. Such tools discover open source code (at various levels of details and capabilities), their direct and indirect dependencies, licenses in effect, and any known security vulnerabilities and potential exploits.

SCA tools are essential in software development and security, enabling developers and organizations to gain visibility into the dependencies and vulnerabilities associated with these components. They provide a comprehensive inventory of software libraries, frameworks, and packages utilized in software stacks or applications, allowing developers to understand the licensing obligations and potential security risks that may arise from incorporating these external resources. SCA tools employ various techniques to assess software components’ integrity, quality, and security. With their ability to automatically track and monitor dependencies, detect vulnerable versions, and provide remediation guidance, SCA tools play a crucial role in ensuring the robustness and security of software applications throughout their lifecycle.

Identifying Whole Components versus Snippets

There is a distinction between identifying open source components and snippets of open source code copied and pasted into new components. While identifying whole components is relatively straightforward, as they can be matched against a comprehensive database of known open source projects, the real challenge lies in accurately identifying snippets of code copied and integrated into new components.

Identifying whole open source components involves comparing the metadata, such as package name and version, against a library or database of known open source projects. This process is relatively easier because the components are usually self-contained entities with clear identification markers. SCA tools excel at this task, providing insights into the use of open source components and their associated licenses.

However, the more complex and challenging task lies in identifying snippets of open source code that have been copied and pasted into new components. This process requires deeper analysis, as snippets may be modified, renamed, or dispersed across different files and directories. Snippet identification involves examining the code structure, algorithms, or unique patterns within the source code to determine their origins.

Identifying snippets is vital to open source compliance because it allows organizations to acknowledge and comply with the specific licensing obligations associated with the copied code. It requires sophisticated techniques, such as code analysis, pattern recognition, and machine learning algorithms, to trace the snippets’ origins and correctly attribute them to their respective open source projects. However, only a few SCA tools offer robust snippet identification capabilities, making it a more challenging and less commonly addressed aspect of open source compliance.

By focusing on snippet identification, organizations can ensure that proper acknowledgments are made to the original authors and that licensing obligations are met for the copied code. This level of granularity in compliance demonstrates a commitment to ethical software practices and helps mitigate legal risks associated with non-compliance.

Snippets Support and License Compliance

Snippet identification plays a pivotal role in open source license compliance.

Fulfill the obligations of open source licenses

Identifying open source snippets in code bases enables organizations to meet their legal obligations. Open source licenses often require proper attribution of the original authors, indicating the open source components used and providing license information. By identifying snippets, organizations can ensure they comply with these obligations and avoid legal repercussions.

Support the effective management of licensing requirements

Different open source licenses have varying terms and conditions, such as copyleft obligations, modification sharing, or adherence to specific license versions. Identifying snippets copied from open source components helps organizations track and understand the licenses and their corresponding obligations, facilitating compliance throughout the software development and distribution process.

Contribute to maintaining the integrity and transparency of the open source community

Open source software thrives on collaboration, knowledge sharing, and attribution of contributors. By accurately identifying and acknowledging snippets, organizations demonstrate their commitment to the principles of the open source ecosystem, building trust and fostering positive relationships within the community.

Furthermore, snippet identification supports companies in managing their intellectual property (IP) rights. By identifying snippets from open source components, organizations can ensure that their proprietary code remains protected, preventing any unintended inclusion of open source code that may conflict with their proprietary licenses or IP rights. This protects the uniqueness and functionality of their software while adhering to licensing obligations and avoiding legal disputes.

Snippets Identification and Security Vulnerabilities

Snippet discovery is crucial in source code scanning from a security perspective. Identifying snippets of code copied from open source components is also essential for effective vulnerability management and risk mitigation. While providing numerous benefits, open source components can also introduce security vulnerabilities. By scanning code and identifying snippets, security teams can detect potential security issues and assess the associated risks.

Snippet discovery allows for a granular examination of the codebase

It enables security professionals to identify known vulnerabilities in specific code segments. This level of visibility facilitates targeted remediation efforts, such as applying patches or updates to the affected snippets. Ultimately, snippet discovery empowers developers to conduct comprehensive security assessments, strengthen the resilience of their codebase, and proactively protect software systems from potential exploits.

Snippet discovery helps prevent the propagation of vulnerable code throughout the software ecosystem

Snippets can inadvertently introduce vulnerabilities into other software components. By actively scanning and identifying snippets, organizations can enhance their overall security posture, minimize the attack surface, and ensure that potential vulnerabilities are promptly addressed, safeguarding their software and protecting against cyber threats.

Snippets Discovery in the Age of AI-Generated Code

In the age of AI-generated code, where machine learning models have been trained on open source code and can produce code snippets that closely resemble those found in open source software and sometimes copied verbatim from open source repositories, the importance of snippet discovery in SCA tools cannot be overstated. As AI systems become more sophisticated and capable of generating code, it becomes crucial to ensure that organizations can detect code snippets copied by AI systems from open source software, adhere to licensing obligations, and maintain compliance.

AI-generated code can pose challenges regarding proper attribution and compliance with open source licenses. The line between code created by humans and code generated by AI systems can become blurred, making it difficult to discern if a code snippet originates from open source software or is AI-generated. However, with the advancement of SCA tools that support snippet discovery, organizations can improve their ability to identify and differentiate between AI-generated code snippets and code derived from open source components.

Organizations are dealing with AI-generated code using various approaches.

Complete Ban

Some organizations are banning the use of generated AI by its developers and even going further as much as not allowing the use of open source packages where it is known that such communities may be using AI-generated code. This is a very conservative approach as many organizations await more clarity on the topic, especially in light of pending litigation.

Internal Use Only

Some organizations allow AI-generated code in specific use cases that do not extend beyond internal use. Such organizations do not allow AI-generated code in their software stack but allow it, for instance, as part of internal use, test cases, exploration of ideas and prototypes, etc.

No Restrictions

Some organizations have a more liberal approach and allow AI-generated code in their code bases conditional to very little or no conditions.

No Formal Policy

Some organizations may not have any policy yet regarding AI-generated code.
