Which of the following physical security controls prevents an attacker from gaining access to a network closet?
A proximity card is a physical card which used to get access to a physical area such as a network closet.
It is a “contactless” smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and
“contact” type smart cards. The proximity cards are part of the Contactless card technologies. Held near an electronic reader for a moment they enable the
identification of an encoded number.
Note: Physical security is the protection of personnel, hardware, programs, networks, and data from physical circumstances and events that could cause serious
losses or damage to an enterprise, agency, or institution. This includes protection from fire, natural disasters, burglary, theft, vandalism, and terrorism.
