Introduction
Security in software development has become a top priority, and rightly so. Supply chain attacks are on the rise, and each new package update represents a potential vulnerability. To counter this risk, GitHub has decided to introduce a default three-day 'cooldown' period for version updates via Dependabot.
Why a Three-Day Cooldown?
The idea behind this cooldown is simple yet effective. When a new version of a package is released, it is immediately available for updates. However, these new versions can introduce bugs or, worse, be compromised. The three-day delay allows the community and maintainers to detect and report any potential issues before the update is merged into your project.
Data on Supply Chain Attacks
In 2023, supply chain attacks increased by 42% according to a report by Sonatype. Cybercriminals are increasingly targeting new packages or version updates to introduce malicious code.
How Dependabot's Cooldown Works
Now, when Dependabot detects a new version, it waits three days before creating a pull request for the update. This requires no configuration on your part. However, GitHub offers the flexibility to modify or disable this delay via the .github/dependabot.yml file if needed.
Exceptions for Security Updates
It is important to note that security updates are not affected by this delay. Critical fixes are opened immediately to ensure vulnerabilities are addressed without delay.
Use Cases and Feedback
Consider a tech company that extensively uses open-source packages. Since the implementation of this cooldown, they have been able to avoid incorporating a package version that contained a critical bug not detected during its initial release. This delay saved them hours of troubleshooting and fixing.
Adoption Statistics
Since its introduction, more than 60% of projects using Dependabot have adopted the default cooldown, according to internal GitHub statistics. This shows rapid adoption and recognition of the usefulness of this measure.
Conclusion
Dependabot's default cooldown is a welcome initiative to enhance software supply chain security. By adding an extra layer of security, developers and decision-makers can focus on innovation while minimizing risks.
