Most modern applications rely on third-party components and dependencies to function. While this open-source code has its benefits, it can also introduce vulnerabilities, malicious code, and other security risks into an application. Software composition analysis (SCA) is a DevSecOps tool for identifying these pieces of external code. SCA can be used to track open-source components, find vulnerabilities, and manage software licenses.
SCA solutions are designed to inspect an unknown codebase and document the open-source components used, their vulnerabilities, and other information. This can be accomplished via the following steps:
At the end of this process, the SCA tool has generated a report that contains information about all of the open-source dependencies used by an application. This information may be reported to security personnel, or, depending on the findings and the level of integration within CI/CD pipelines, may even block new commits from being added to the codebase if they use deprecated or insecure components.
By integrating SCA into CI/CD pipelines, developer teams can shift security left and reduce the risk of exploitable vulnerabilities reaching production systems.
Supply chain attacks have become a growing threat to application security. Many applications rely upon open-source components that contain vulnerable code. Cybercriminals are also actively working to develop libraries or inject malicious code into legitimate ones to undermine application security.
SCA provides an organization with visibility into the third-party code that its applications rely upon. This visibility is essential to identify inherited vulnerabilities and other issues that might arise from the use of open-source and third-party code.
SCA provides visibility into the open-source dependencies that an organization’s applications use. This visibility is essential for vulnerability and license management.
Open-source libraries can contain exploitable vulnerabilities or malicious code. If an application imports these libraries, it may be vulnerable to exploitation or execute the malicious code. Often, companies struggle to maintain visibility into the third-party code that it uses. This is especially true of indirect dependencies where one open-source component imports one or more others. SCA solutions can help companies to gain the visibility that they need and rapidly determine if CVEs exist for the versions of the libraries used by the application.
The use of third-party code can create licensing issues for an organization, especially with the wide range of potential licensing requirements. At one extreme, copyrights may make it impossible for a company to use a component or may require payment of royalties. At the other, copyleft licenses can mandate that any code using a particular component must also be freely available and open source.
Without visibility into the open-source components used by its applications, an organization is in the dark about licensing rules and may be in legal jeopardy. By collecting licensing information about all open-source components used within a codebase, a company can achieve visibility into potential licensing and legal issues.
Increasingly, cyber threat actors are performing supply chain attacks, where vulnerabilities or malicious code are injected into open source projects used by other applications. The software that imports the library will execute the malicious code or inherit vulnerabilities that open them up to exploitation.
SCA can help protect against supply chain attacks by identifying vulnerabilities in an application’s dependencies. Additionally, insight into the dependencies used by an application can help with the identification of known-bad libraries that were created or compromised by cybercriminals for these attacks.
SCA is essential to managing an organization’s software supply chain security risks. However, SCA faces challenges, including the following:
As applications grow more dependent on complex networks of open-source dependencies, monitoring and managing these dependencies becomes more complex. The main benefit of SCA is that it enables development teams to rapidly generate an SBOM and use this information to identify potential vulnerabilities and licensing issues in their software.
