Question 81

A text file containing sensitive information about the organization has been leaked and modified to bring down the reputation of the organization. As a safety measure, the organization did contain the MD5 hash of the original file. The file which has been leaked is retained for examining the integrity. A file named "Sensitiveinfo.txt" along with OriginalFileHash.txt has been stored in a folder named Hash in Documents of Attacker Machine-1. Compare the hash value of the original file with the leaked file and state whether the file has been modified or not by selecting yes or no.

A.No
B.Yes

Question 82

Charlie, a security professional in an organization, noticed unauthorized access and eavesdropping on the WLAN. To thwart such attempts, Charlie employed an encryption mechanism that used the RC4 algorithm to encrypt information in the data link layer. Identify the type of wireless encryption employed by Charlie in the above scenario.

A.TKIP
B.WEP
C.AES
D.CCMP

Correct Answer: B

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 Code Protocol) 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

Question 83

NexaBank, a prestigious banking institution, houses its primary data center in Houston, Texas. The data center is essential as It holds sensitive customer Information and processes millions of transactions daily. The bank, while confident about its cybersecurity measures, has concerns regarding the physical threats given Houston's susceptibility to natural disasters, especially hurricanes. The management understands that a natural disaster could disrupt services or, worse, compromise customer data. The bank Is now weighing options to enhance its physical security controls to account for such external threats.
For NexaBank's data center In Houston, which is the most critical physical security control it should consider implementing?

A.Bulletproof glass windows and fortified walls.
B.Flood-resistant barriers and drainage systems.
C.Deploy additional armed security personnel.
D.Advanced CCTV surveillance with facial recognition.

Question 84

Richard, a professional hacker, was hired by a marketer to gather sensitive data and information about the offline activities of users from location dat a. Richard employed a technique to determine the proximity of a user's mobile device to an exact location using CPS features. Using this technique. Richard placed a virtual barrier positioned at a static location to interact with mobile users crossing the barrier, identify the technique employed by Richard in this scenario.

A.Containerization
B.Over-the-air (OTA) updates
C.Full device encryption
D.Ceofencing

Question 85

Lorenzo, a security professional in an MNC, was instructed to establish centralized authentication, authorization, and accounting for remote-access servers. For this purpose, he implemented a protocol that is based on the client-server model and works at the transport layer of the OSI model.
Identify the remote authentication protocol employed by Lorenzo in the above scenario.

A.SNMPv3
B.RADIUS
C.POP3S
D.IMAPS

Correct Answer: B

The correct answer is B, as it identifies the remote authentication protocol employed by Lorenzo in the above scenario. RADIUS (Remote Authentication Dial-In User Service) is a protocol that provides centralized authentication, authorization, and accounting (AAA) for remote-access servers such as VPNs (Virtual Private Networks), wireless networks, or dial-up connections. RADIUS is based on the client-server model and works at the transport layer of the OSI model. RADIUS uses UDP (User Datagram Protocol) as its transport protocol and encrypts only user passwords in its messages. In the above scenario, Lorenzo implemented RADIUS to provide centralized AAA for remote-access servers. Option A is incorrect, as it does not identify the remote authentication protocol employed by Lorenzo in the above scenario. SNMPv3 (Simple Network Management Protocol version 3) is a protocol that provides network management and monitoring for network devices such as routers, switches, servers, or printers. SNMPv3 is based on the manager-agent model and works at the application layer of the OSI model. SNMPv3 uses UDP as its transport protocol and encrypts all its messages with AES (Advanced Encryption Standard) or DES (Data Encryption Standard). In the above scenario, Lorenzo did not implement SNMPv3 to provide network management and monitoring for network devices. Option C is incorrect, as it does not identify the remote authentication protocol employed by Lorenzo in the above scenario. POP3S (Post Office Protocol version 3 Secure) is a protocol that provides secure email access and retrieval for email clients from email servers. POP3S is based on the client-server model and works at the application layer of the OSI model. POP3S uses TCP (Transmission Control Protocol) as its transport protocol and encrypts all its messages with SSL (Secure Sockets Layer) or TLS (Transport Layer Security). In the above scenario, Lorenzo did not implement POP3S to provide secure email access and retrieval for email clients from email servers. Option D is incorrect, as it does not identify the remote authentication protocol employed by Lorenzo in the above scenario. IMAPS (Internet Message Access Protocol Secure) is a protocol that provides secure email access and management for email clients from email servers. IMAPS is based on the client-server model and works at the application layer of the OSI model. IMAPS uses TCP as its transport protocol and encrypts all its messages with SSL or TLS. In the above scenario, Lorenzo did not implement IMAPS to provide secure email access and management for email clients from email servers.
