Reduced SSL/TLS Certificate Validity: Google Advocates for Limiting Certificate Period to a Minimum of 90 Days!
==================================================================================
Google has put forth a proposal to revise the SSL/TLS certificate system, aiming to reduce the maximum validity period to 90 days. This change, if implemented, could significantly impact online security for both website owners and users alike.
The Proposed Change
The central idea behind Google's proposal is to keep users' sensitive data safe by enforcing more frequent certificate renewals. By reducing the certificate lifetimes to 90 days, Google believes that it will enhance online security by encouraging more frequent updates and adherence to current security standards.
Benefits
The benefits of this change are manifold. Firstly, shorter certificate lifetimes reduce the risk associated with compromised or misissued certificates, as attackers have a smaller timeframe to exploit them[1][5].
Secondly, a 90-day validity sets a practical limit encouraging website operators to implement automated certificate issuance and renewal processes, promoting more consistent certificate hygiene[1].
Lastly, with shorter validity, certificates that are no longer in use expire sooner, reducing the number of outdated or abandoned certificates trusted by browsers[5].
Drawbacks
However, this change also introduces some challenges. Sites without automated renewal systems face frequent manual renewals that are time-consuming, error-prone, and costly[2].
Misconfigured or failed renewals could cause website outages or trust warnings if certificates expire unexpectedly[1]. Additionally, the proposal is limited to Domain Validation (DV) certificates, which may not provide the higher assurance levels of Organization Validated (OV) or Extended Validation (EV) certificates for businesses requiring such levels for sensitive transactions[2].
Implications
The proposal may have implications on the certificate ecosystem, as CAs and other stakeholders must adapt their infrastructure and policies to support rapid issuance cycles and automation, which can be challenging and costly in the short term[5].
Stay Informed
As the proposal develops, it's important for all parties to stay informed about the potential impacts of the proposal on their online security. It's crucial for website owners and users to take steps to protect themselves accordingly.

The encyclopedia of cybersecurity might include an entry on Google's proposal to reduce SSL/TLS certificate validity, discussing its potential benefits such as reduced risk of compromised certificates, promotion of automated renewal processes, and decreased number of outdated certificates. On the other hand, challenges in this proposal could include time-consuming, error-prone, and costly manual renewals for sites without automated systems, and limitations in providing higher assurance levels for sensitive transactions. Authorities in the certificate ecosystem must adapt to support this proposal, facing challenges and costs in the short term.
