A Complete Handbook to Software Composition Analysis (SCA)

Open-source code spreads throughout every corner of the digital landscape, requiring effective management strategies (like implementing Software Composition Analysis) to reduce security risks.

Developers have the job of creating engaging and reliable apps more quickly. To do this, they depend on open-source code to easily add features to their own software. Since open-source code makes up around 60-80% of the code in these proprietary applications, handling it well is really important to reduce an organization’s security risk.

Tools for Software Composition Analysis assist in the management of open-source usage.

What is Software Composition Analysis?

Software composition analysis (SCA) is an automated procedure that detects the open-source software present in a codebase. The analysis is actively assessing security, ensuring adherence to licenses, and evaluating the code quality.

Companies must be conscious of the limitations and obligations imposed by open-source licenses. The manual monitoring of these commitments became overly burdensome and frequently missed out on code and associated vulnerabilities. The automated remedy SCA is then introduced to address this challenge an automated remedy. Originally devised for handling obligations, SCA’s scope broadened to encompass the scrutiny of code security and overall quality.  Within a modern DevOps and DevSecOps environment, SCA has strongly reinforced the “shift left” approach. With earlier SCA testing and consistency throughout, developers and security teams can enhance efficiency while upholding both security and quality standards.

What is the purpose of a SCA tool?

In almost every industry, open-source components are increasingly important building blocks of software. SCA tools assist in monitoring the open-source components integrated into your applications, a vital aspect for both efficiency and security considerations.

The cost of a security breach

Gartner’s assessment reveals that over 70% of applications harbour issues arising from open-source usage. The Equifax incident exemplifies the dire consequences of such flaws, emphasizing that timely action is crucial. In the Equifax breach, the attackers exploited a vulnerability in the widely used open-source Java library, Apache Struts. Despite Apache’s fix being available within weeks, Equifax failed to address it before attacks occurred, resulting in costly repercussions.

This breach acted as a pivotal point for application security and the broader security sector, highlighting the necessity of robust measures for handling open-source risks. The incident underscored the need for swift response and continuous vigilance. Yet, post-event surveys, like Tidelift’s 2022 Open Source Supply Chain report, indicate that even with modern security tools, 57% of surveyed businesses encountered challenges identifying and resolving open-source-related vulnerabilities during development.

This is where Software Composition Analysis (SCA) plays a pivotal role.

Why is software composition analysis (SCA) important?

Security, speed, and reliability are what make SCA valuable. The manual monitoring of open-source code is inadequate due to its inability to cope with the vast volume of open-source components. The growing prevalence of cloud-native applications and increasingly intricate software necessitates the presence of reliable and effective SCA tools.

Organizations need security solutions capable of sustaining development speed amidst the rapid pace of development brought about by the integration of DevOps practices. Tools for automated SCA accomplish this.

How does SCA functions?

SCA solutions are made to examine an unidentified codebase and record the open-source components utilized, their flaws, and other details. The steps listed below can be used to achieve this:

• Scanning: To identify the libraries and dependencies utilized by the code, an SCA tool will first scan a codebase. Based on the result of the scan, a tool can provide a Software Bill of Materials (SBOM) that lists every piece of open-source software that the programme has utilised.
• Documentation: Information on the usage of the application, the licensing details, and the version of the software are all useful. An SCA scanner will record this information after determining the presence of open-source code in a database.
• Vulnerability Detection: Using common vulnerabilities and exposures (CVEs), we document known vulnerabilities along with the affected software and versions. An SCA tool can locate known vulnerabilities in the application by leveraging the knowledge of open-source libraries being used and their version numbers.

At the end of the process, SCA tools produce a report containing an application’s open-source dependencies. This report can be shared with security personnel or utilized to prevent further insecure commits. Incorporating SCA into CI/CD pipelines brings security into focus earlier in the development process, thereby reducing the potential for production vulnerabilities.

Benefits of Software Composition Analysis

The significance of SCA lies in the advantages it delivers in terms of security, swiftness, and dependability. Traditional manual oversight of open-source code has become inadequate due to the overwhelming volume of open-source content. Moreover, the rise of cloud-native applications and intricate software necessitates the adoption of robust and trustworthy SCA tools.

With the rapid implementation of DevOps practices accelerating the development pace, organizations require security solutions capable of upholding this increased velocity. Automated SCA tools do just that. 

Challenges In Software Composition Analysis

• Obscured visibility
  Integrating open-source code presents visibility hurdles due to hidden indirect dependencies, often multiple layers deep. According to Snyk’s analysis, node.js, java, and Ruby, transitive dependencies are the cause of 86% of vulnerabilities. This is made worse by cloud-native apps’ use of multilayer containers and open source, which makes it difficult to identify and test them. Containers’ developmental benefit from abstractions turns into a security flaw.
• Understanding the dependency logic
  A comprehensive grasp of how each ecosystem manages dependencies is necessary to accurately identify the dependencies an application is using as well as the vulnerabilities they bring. Variables such as lock files, development dependencies, and package resolution during installation influence how open-source package vulnerabilities are discovered and will impact the subsequent steps in remediation. To avoid overstimulation with false positives, a SCA solution must be aware of these nuances.
•  Drowning in vulnerabilities
  Organizations lack visibility into risk because of a vast number of vulnerabilities discovered, as demonstrated by the Synk Intel database adding over 10,000 vulnerabilities. These rising patterns affect vulnerability backlogs, which frequently contain thousands of concerns. Without integrating advanced security experience, or skills, development and security teams struggles to prioritize with limited resources. Although people frequently use CVSS-based severities for risk assessment, their usage becomes complicated due to inherent flaws.
• Find me a vulnerability database
  Numerous data sources are used to disseminate and diffuse information about identified vulnerabilities. Receiving updates on vulnerabilities from the National Vulnerability Database (NVD) is a usual practise. There is also a significant quantity of security information about vulnerabilities that is accessible from other sources, including issue trackers, online discussion forms, newsletters, and more. Additionally, it is possible that NVD won’t add vulnerabilities quickly enough. For instance, 92% of the Javascript flaws in NVD were added to Snyk previously. Given this requirement for as-soon-as-possible for exposure windows, this latency may be possible. Early detection of a vulnerability can make all the difference.
• The need for speed
  Security struggles to catch up as developers advance at a rapid pace. Encouraging Open source speeds up coding, but security measures taken at different phases of development often lead to delays. The lack of resources makes it possible to get around security measures, which led to the emergence of DevSecOps and Shifting Left. With this strategy, security is integrated into development to reduce interruption and maintain security. This is in line with new-generation SCA technologies, which enable early open-source security testing. Snyk’s developer-focused strategy supports shift-left even more.
