The recent decision to reduce TLS certificate lifetimes to 47 days has sparked various opinions regarding its implications for security and management practices. Many users highlight that large companies are already transitioning to internally signed certificates due to the increasingly shorter expiration times of public certificates. This change could complicate certificate management for enterprise applications and mobile apps, as automatic rotations might lead to issues with certificate pinning. Concerns are expressed about security risks tied to frequent certificate updates, especially with the reliance on external certificate authorities (CAs) and the potential for increased vulnerability during certificate theft or compromise incidents. There are insights shared about the challenges hardware devices face with certificate renewal processes, as many devices are not equipped for automated updates, which may lead to operational difficulties. Overall, while the intent is to bolster security through shorter lifetimes, the practical challenges of managing such a policy may introduce new risks.
