hmmm....
could be bad if the attacker is on the same intranet. for example, a
local employee connects and registers a name such as att.company.com.
your certs use *.company.com. the attacker will be in possition to exploit.

do wildcard SSL cert's have a bigger security risk?

we are building 4 new servers for our internal intranet staff directory.
we will have a c-name for each server.

this way we can point any c-name at any server for DR and maintance outages.

the old system was to have an SSL cert for each server.
svr1.intranet.company.com
svr2.intranet.company.com
svr3.intranet.company.com
svr4.intranet.company.com

problem is that if we re-point a c-name we will get a SSL cert mis-match.

my plan is to make each server use a wildcard SSL cert of
*.intranet.company.com
I know my solution will solve the problem but is it a security risk?
is this a bad thing?

what security risks am I opening up?

thanks
