Managing Certificates

Short-Lived Certificates

Short-lived certificate refers to an SSL/TLS certificate that is issued with a very short validity period, typically ranging from a few days to a few months. These typically reduce the risk associated with certificates that might be compromised or misused over time. By limiting their validity, the attack surface is minimized because certificates are rotated more frequently.

Benefits of Short-Lived Certificates
  • Improved Security: Short-lived certificates lower the impact of a potential compromise since certificates are valid only for a short period.
  • Encourages Automation: With shorter validity periods, the use of automated tools (like ACME protocol for certificate management and many more MDM tools) becomes more common. This encourages the automation of certificate renewal, which reduces human errors and increases operational efficiency.
  • Faster Revocation: If a certificate is compromised, revocation becomes more effective because the certificate will expire quickly anyway.
