Source code protection: 3 DLP tools at a glance (2023)

  • Published

Source code security is critical to protecting software from malicious attacks and security breaches. Fortunately, powerful tools are available to detect potential vulnerabilities.

Protect source code with data loss prevention tools

Data loss prevention tools (DLP) are software solutions designed to prevent the loss or disclosure of sensitive data. To do this, these tools monitor the flow of data within a network.

Companies set policies to ensure that data is protected. When a potential breach is detected, the software can take action to block or prevent the unauthorised data flow.

Data leaks and data theft can be combated by applying security policies to the source code. For example, it detects when code is copied into an email or onto a storage device such as a USB stick, or uploaded to websites.

The functionality of DLP tools usually includes:

  • Content monitoring: Data in various formats are analysed, e.g. in text files, emails or file attachments.
  • Data Classification: The tools enable the categorisation of data based on its sensitivity and the level of protection it requires.
  • Data Discovery: Servers, databases and other storage locations are scanned to find sensitive data that is unprotected or inadequately secured.
  • Data Loss Prevention Policies: Companies define individual policies on how data should be handled. The tool ensures that the policies are enforced.
  • Incident Response: DLP tools send alerts when dangerous activities or policy violations are detected.

How do you protect source code without DLP tools and already in the first step of software development?

DLP tools offer a comprehensive way to protect sensitive data and source code from being leaked or stolen. Another way you can increase source code security is through Remote Development Environments (RDEs) or Cloud Development Environments (CDEs).

RDEs are remote environments in which developers have all the tools they need for their work. RDEs claim to make local development environments obsolete.

Some RDE providers make it possible that the source code and test data are not stored locally on the developer’s laptop. For example, with Cloudomation DevStack, you have the option of storing the source code exclusively on the RDEs and developers are not allowed to download it. The risk of theft or loss of the source code is therefore already prevented during day-to-day work.

Conclusion

  • Data loss prevention tools (DLP) can be used to prevent the misuse of data. These tools monitor the data flow within a network.
  • Providers of remote development environments (such as Cloudomation) sometimes offer the option that the source code and test data are not stored locally on the developers’ laptops. This increases security within the development team.
