Code Signing In The DevOps Era: Silver Bullet Or Security Theater?
DevOps.com, Saturday, June 14th, 2025
In my work with global enterprises modernizing their DevSecOps practices, I've repeatedly seen a troubling pattern: Organizations implement code signing with good intentions, but without the controls to support it.
In one recent engagement, a team proudly showcased their secure pipeline - automated builds, signed containers and rapid deployments. But during a code audit, we found a private signing key embedded in a script, committed to version control, with no rotation or monitoring. That key had been used to sign production artifacts. If it had been compromised and we couldn't be sure it hadn't - an attacker could have shipped malicious code, fully 'trusted' by their infrastructure.
This isn't rare. Code signing is often deployed as a checkbox, not as part of a robust trust framework. And that creates a dangerous illusion of security.
