Yes, certificate missery.
In the wisdom of great corperations, for our safety, it is deiced that the maximum SSL/TLS certificate validity is one year.
Yes, really… don’t believe me, just check this search for it
ssl lifetime 1 year at DuckDuckGo
From the security side of things this is a good thing. Because it mitigates the risk of a hacked certificate.
But from an administration point of view….. HEADACHE.
Especially for certificates that are used internally in your production sites.
Now you need to replace the certificates every year for your servers.
At least for those servers that run web services because your browser is going to nag you that the site isn’t safe anymore. Yes another warning.
And you know what happens to warnings, in the end they will think for you, and won’t allow you to access the website anymore.
so SSL certificate monitoring becomes more importent, and having a plan / replacement strategy for SSL certificates would be a good thing to have.
Do you have an up-to-date overview of all the SSL certificates in your network ?
Maybe a good idea to have it up-to-date and monitor them.
