Thanks for that reminder Noci. I recall that bit from a couple of years ago when I last had to apply a cert now that you mention it!

If someone else in your company already requested a wildcard certificate and is using it - can you just use that certificate for your device? e.g. suppose a sysadmin generated a CSR for *.foo.com to put on his IIS server. He saves that cert to a shared drive and installs it on his IIS server. A few months go by and he decides to put a load balancer in front of the IIS server. The VIP on the load balancer will also need *.foo.com. So I think the previously generated wildcard certificate can just be installed. Correct? Or would a new CSR have to be generated from the load balancer for *.foo.com? Thank you for clarifying.

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
