Security Audit Software Open Source

Open source software audits can identify undetected issues in your codebase. Learn how our audit services can help you understand the risks during an M&A.

Most of our clients understand that an open source software audit differs from an automated scan. An audit involves expert consultants analyzing a proprietary codebase using a combination of Black Duck® commercial tools and tools we’ve developed and use internally.

The deliverable is a report that identifies open source in the code as well as associated risks. If you’d like to understand our process—what comes before, during, and after—read on. Generally, customers who come to us are either acquirers looking to have Black Duck perform an open source software audit on the code of their target, or companies wanting us to audit their own code in anticipation of being acquired.

Comparison Chart of Free & Open-Source Audit Software

  1. There are other use cases as well; for example, it’s becoming more common for investors, lenders, and IP insurers to require or encourage Black Duck audits. Commonly during an M&A transaction, there is significant time pressure.
  2. So it’s critical, first thing, to scope the job, allowing all parties to quickly understand the time and costs involved.
  3. We regularly amaze customers with our responsiveness when we get called in at the last minute, but scoping early can save everyone time and money (and headaches).
  4. I hate to hear customers or their counsel say, “We didn’t want to bring you in earlier, because we weren’t sure about the deal.” Don’t worry about us—in fact, lean on us.
  5. As soon as you think it’s appropriate, we are happy to get to work even understanding that the audit might never materialize. We start by assigning a project manager to work with the code owner, often a third party in an M&A transaction, to get a high-level view of the composition and complexity of the codebase and its architecture.
  6. We try to be sensitive to the pressure on them while also keeping the deal moving. In great part, the scope of work is driven by the number of files and the prevalence of open source components in the technologies used.
  7. For example, JavaScript tends to be full of open source files, whereas a typical C++ codebase contains less open source.
  8. In the great majority of cases, because of Black Duck’s experience and reputation, code owners are comfortable securely uploading code to Synopsys servers.
  9. We don’t require code access to scope, but it’s the most common and best method, as it’s the most efficient way to do the work.
  10. Audits rarely need to be done onsite. The benefits to this approach include minimizing costs and time, and maximizing flexibility.
  11. For example, if the job expands and more resources are necessary or a transaction gets put on hold, we are limited with people onsite.
  12. Before the audit commences, there’s a bit of paperwork required, including an NDA with the third-party code owner.
  13. Ultimately the work is agreed to with our customer in a Statement of Work that describes work to be done, codebase, schedule, and fixed price.
  14. Open source audits continue to be our flagship offering, and we do them for almost every client.


But many rely on us for a broader range of software due diligence needs, including code quality, application security, and evaluating the software development process.

Each of those areas are specialized, so although clients might not perceive it, auditors have various areas of expertise, and different auditors focus on different services.

  • As soon as they have access to the code, expert auditors begin by identifying open source and other third-party components.
  • This is semiautomated, meaning that identification relies on an excellent set of tools as well as the expertise of auditors.
  • For comprehensiveness, Black Duck tools employ a variety of techniques to ferret out unknown open source.
  • In many cases, the tools definitively identify components, but sometimes, due to limited information in the code, they just provide clues to support auditors’ detective work.
  • The result of this identification process is a comprehensive software Bill of Materials (SBOM).
  • Essentially this is a list of the open source components in the codebase.
  • We often identify other third-party software as well, by digging through copyright statements in source code.

The audit

The SBOM is the foundation for identifying open source risks. Only by knowing what’s in the code can you know the associated risks. We then enumerate three types of risks associated with open source: legal, security, and operational:.

Legal risks are primarily the result of using a component in a way that conflicts with the terms and/or obligations of the open source license.

  • Security risks stem from using components that have known security vulnerabilities, usually older versions that have not been patched.
  • Operational risks come with components that are particularly out-of-date or inactive.
  • In addition to identifying the issues, audit reports provide red/yellow/green rankings for each issue to help with prioritization.
  • We wrap the SBOM and risks into a set of reports that we deliver to our customer via a secure portal.
  • Customers can share internally with advisors and, sometimes, with targets.

We always offer and recommend a post-audit review call during which our project manager walks through the report and answers questions about how it was generated and the results. Ideally, the call includes customer staff or advisors who can interpret the implications of the risks in light of the customer’s unique situation.

It almost always makes sense to have legal counsel involved, ideally someone familiar with open source licensing. And it’s generally a good idea to have someone there familiar with the architecture of the codebase and someone who understands cyber security. The extent and severity of the issues identified varies, but there is almost always some cleanup required.

Final thoughts

  • In the case of an acquisition, the closing may wait for remediation, or the parties can agree to take care of things after the close.
  • In some scenarios, customers want to verify that all identified issues have been addressed.
  • After remediation, we can perform a verification scan, and provide a new, presumably clean report.
  • If the customer anticipates this, we will retain the original results and so we can perform the follow-up work much more quickly and efficiently.
  • How do our audits work? Generally, very well. Having performed thousands of them, we’ve refined our processes to minimize stress on all parties and to enable us to meet tight schedules.


  • At the same time, we maintain the flexibility to meet customers’ specific needs. If there is anything you need, just let us know.

There are many benefits to using open source software as part of your development process, a few of which include: . Increased time to market. Create software faster by connecting existing components together, rather than implementing them all from the ground up.

What are the key features of an audit management software solution?

Higher quality. All software components may contain defects, but focused effort on specialized software components often results in higher quality than having many engineers solving the same problems many times in isolation. By contributing new features, reporting bugs, or in general interacting with the open source projects used, you're sharing in both the costs and benefits of the code base. At Microsoft, we recognize the benefits of using open source responsibly when developing products and services and encourage our customers and the larger technology community to do the same.

Open source, like any software, can contain security defects, which can become manifest as vulnerabilities in the software systems that use them.

Since source code is generally available for open source components, it can often be easier for security researchers to identify new vulnerabilities, and while most researchers will follow responsible disclosure methods when reporting issues to the maintainer, there is a risk that some vulnerabilities will become weaponized and used to attack systems that use them.

Exacerbating this, open source components are generally released as needed, often with little to no advance notice to the user community, so when a vulnerability is fixed and a new release is published, there is often a lag until users can upgrade to the new version; this lag can give adversaries time to create and launch an exploit.

What is audit management?

As a result, it's very important to update open source components in a timely manner, especially when they contain security fixes. Software organizations typically interact with the open source community in a few different ways: .

Use—integrating open source components within an application.

  • Distribute—Releasing an application or component under an open source license.
  • Collaborate—accepting external contributions (for example via pull requests) to distributed open source components.
  • Contribute—Submitting patches or pull requests to external open source components.
  • The first item, “use”, presents the clearest security risk to most organizations due to how vulnerabilities in those components can affect the security of the systems that use them.

Majority of the companies doing business in regulatory environments need timely and efficient audits to ensure that the business runs smoothly. To accomplish quality and compliance; companies can simplify their audit processes by making use of audit management software.

Network Security Auditing FAQs

How does an IT audit differ from a security assessment?

An IT security audit checks that specific security controls are in place. A cybersecurity assessment is a high-level study that determines the effectiveness of those cybersecurity controls and rates an organization’s cybersecurity preparedness. Audits follow a list of requirements, such as those specified by HIPAA or PCI DSS and assessments make sure a company is secure against all known current cybersecurity attack strategies.

How often should security audits be performed?

A system that is high risk or new should be audited quarterly. Stable systems can be audited twice a year.

How do you audit cloud security?

Cloud security audits are not much different to audits of on-premises systems. The audit will be tailored according to any standards that the company works to, such as HIPAA or PCI DSS.
