I am working on standardizing our server builds where we currently have three different functional pools.
For web pools I use the same IIS RSA key across all machines. It keeps life easy and allows the application.config file to be copied between servers without issue.
My question is, is there any issue of have all servers us the same RSA key, so there is only one key pair to maintain and use when standing up new servers?
Are there security concerns with doing this were the keys should be different in different functional pools?
