Availability is the information security element that ensures that Stella’s transaction status is immediately reflected in her bank account in this scenario. Information security is the practice of protecting information and information systems from unauthorized access, use, disclosure, modification, or destruction. Information security can be based on three fundamental principles: confidentiality, integrity, and availability. Confidentiality is the principle that ensures that information is accessible only to authorized parties and not disclosed to unauthorized parties. Integrity is the principle that ensures that information is accurate, complete, and consistent and not altered or corrupted by unauthorized parties. Availability is the principle that ensures that information and information systems are accessible and usable by authorized parties when needed. In the scenario, Stella purchased a smartwatch online using her debit card. After making payment for the product through the payment gateway, she received a transaction text message with a deducted and available balance from her bank. This means that her transaction status was immediately reflected in her bank account, which indicates that availability was ensured by her bank’s information system. 

WEP is the type of wireless encryption employed by Charlie in the above scenario. Wireless encryption is a technique that involves encoding or scrambling the data transmitted over a wireless network to prevent unauthorized access or interception. Wireless encryption can use various algorithms or protocols to encrypt and decrypt the data, such as WEP, WPA, WPA2, etc. WEP (Wired Equivalent Privacy) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer . WEP can be used to provide basic security and privacy for wireless networks, but it can also be easily cracked or compromised by various attacks . In the scenario, Charlie, a security professional in an organization, noticed unauthorized access and eavesdropping on the WLAN (Wireless Local Area Network). To thwart such attempts, Charlie employed an encryption mechanism that used the RC4 algorithm to encrypt information in the data link layer. This means that he employed WEP for this purpose. TKIP (Temporal Key Integrity Protocol) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer with dynamic keys . TKIP can be used to provide enhanced security and compatibility for wireless networks, but it can also be vulnerable to certain attacks . AES (Advanced Encryption Standard) is a type of wireless encryption that uses the Rijndael algorithm to encrypt information in the data link layer with fixed keys . AES can be used to provide strong security and performance for wireless networks, but it can also require more processing power and resources . CCMP (Counter Mode with Cipher Block Chaining Message Authentication CodeProtocol) is a type of wireless encryption that uses the AES algorithm to encrypt information in the data link layer with dynamic keys . CCMP can be used to provide robust security and reliability for wireless networks, but it can also require more processing power and resources

The correct answer is B, as it identifies the type of account that the organization has given to Sam in the above scenario. A guest account is a type of account that allows temporary or limited access to a system or network for visitors or users who do not belong to the organization. A guest account typically has minimal privileges and permissions and can only access certain files or applications. In the above scenario, the organization has given Sam a guest account for the demonstration. Using this account, Sam can only access the files that are required for the demonstration and cannot open any other file in the system. Option A is incorrect, as it does not identify the type of account that the organization has given to Sam in the above scenario. A service account is a type of account that allows applications or services to run on a system or network under a specific identity. A service account typically has high privileges and permissions and can access various files or applications. In the above scenario, the organization has not given Sam a service account for the demonstration. Option C is incorrect, as it does not identify the type of account that the organization has given to Sam in the above scenario. A user account is a type of account that allows regular access to a system or network for employees or members of an organization. A user account typically has moderate privileges and permissions and can access various files or applications depending on their role. In the above scenario, the organization has not given Sam a user account for thedemonstration. Option D is incorrect, as it does not identify the type of account that the organization has given to Sam in the above scenario. An administrator account is a type of account that allows full access to a system or network for administrators or managers of an organization. An administrator account typically has the highest privileges and permissions and can access and modify any files or applications. In the above scenario, the organization has not given Sam an administrator account for the demonstration.
