Leo has walked to the nearest supermarket to purchase grocery. At the billing section, the billing executive scanned each product's machine-readable tag against a readable machine that automatically reads the product details, displays the prices of the individual product on the computer, and calculates the sum of those scanned items. Upon completion of scanning all the products, Leo has to pay the bill.Identify the type of short-range wireless communication technology that the billing executive has used in the above scenario.

Radio-frequency identification (RFID)

Hayes, a security professional, was tasked with the implementation of security controls for an industrial network at the Purdue level 3.5 (IDMZ). Hayes verified all the possible attack vectors on the IDMZ level and deployed a security control that fortifies the IDMZ against cyber-attacks.Identify the security control implemented by Hayes in the above scenario.

Use of authorized RTU and PLC commands

Paul, a computer user, has shared information with his colleague using an online application. The online application used by Paul has been incorporated with the latest encryption mechanism. This mechanism encrypts data by using a sequence of photons that have a spinning trait while traveling from one end to another, and these photons keep changing their shapes during their course through filters: vertical, horizontal, forward slash, and backslash.Identify the encryption mechanism demonstrated in the above scenario.

Rivest Shamir Adleman encryption

Question 1 / 40

Rickson, a security professional at an organization, was instructed to establish short-range communication between devices within a range of 10 cm. For this purpose, he used a mobile connection method that employs electromagnetic induction to enable communication between devices. The mobile connection method selected by Rickson can also read RFID tags and establish Bluetooth connections with nearby devices to exchange information such as images and contact lists.

Which of the following mobile connection methods has Rickson used in above scenario?

NFC

Satcom

Cellular communication

ANT

Comment (1)

Suggested answer: A

Explanation:

NFC (Near Field Communication) is the mobile connection method that Rickson has used in the above scenario. NFC is a short-range wireless communication technology that enables devices to exchange data within a range of 10 cm. NFC employs electromagnetic induction to create a radio frequency field between two devices. NFC can also read RFID tags and establish Bluetooth connections with nearby devices to exchange information such as images and contact lists . Satcom (Satellite Communication) is a mobile connection method that uses satellites orbiting the earth to provide communication services over long distances. Cellular communication is a mobile connection method that uses cellular networks to provide voice and data services over wireless devices. ANT is a low-power wireless communication technology that enables devices to create personal area networks and exchange data over short distances.
