On your server rooms / data centres, do you have an unescorted access control listing posted at the door or whatever you use as an entry point? I have seen these all over our facility but I am not really sure of the rationale behind why people use them? What security benefits or accountability benefits do they bring?

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.
