Riley sent a secret message to Louis. Before sending the message, Riley digitally signed the message using his private key. Louis received the message, verified the digital signature using the corresponding key to ensure that the message was not tampered during transit.
Which of the following keys did Louis use to verify the digital signature in the above scenario?
A. Louis's public key
B. Riley's public key
C. Louis's private key
D. Riley's private key
答案：B
解題說明：
Riley's public key is the key that Louis used to verify the digital signature in the above scenario. A digital signature is a cryptographic technique that verifies the authenticity and integrity of a message or document. A digital signature is created by applying a hash function to the message or document and then encrypting the hash value with the sender's private key. A digital signature can be verified by decrypting the hash value with the sender's public key and comparing it with the hash value of the original message or document . Riley's public key is the key that corresponds to Riley's private key, which he used to sign the message. Louis's public key is the key that corresponds to Louis's private key, which he may use to encrypt or decrypt messages with Riley. Louis's private key is the key that only Louis knows and can use to sign or decrypt messages. Riley's private key is the key that only Riley knows and can use to sign or encrypt messages.

Ayden works from home on his company's laptop. During working hours, he received an antivirus software update notification on his laptop. Ayden clicked on the update button; however, the system restricted the update and displayed a message stating that the update could only be performed by authorized personnel.
Which of the following PCI-DSS requirements is demonstrated In this scenario?
A. PCI-DSS requirement no 1.3.1
B. PCI-DSS requirement no 53
C. PCI-DSS requirement no 1.3.2
D. PCI-DSS requirement no 5.1
答案：B
解題說明：
PCI-DSS requirement no 5.3 is the PCI-DSS requirement that is demonstrated in this scenario. PCI-DSS (Payment Card Industry Data Security Standard) is a set of standards that applies to entities that store, process, or transmit payment card information, such as merchants, service providers, or payment processors. PCI-DSS requires them to protect cardholder data from unauthorized access, use, or disclosure. PCI-DSS consists of 12 requirements that are grouped into six categories: build and maintain a secure network and systems, protect cardholder data, maintain a vulnerability management program, implement strong access control measures, regularly monitor and test networks, and maintain an information security policy. PCI-DSS requirement no 5.3 is part of the category "maintain a vulnerability management program" and states that antivirus mechanisms must be actively running and cannot be disabled or altered by users, unless specifically authorized by management on a case-by-case basis for a limited time period. In the scenario, Ayden works from home on his company's laptop. During working hours, he received an antivirus software update notification on his laptop.
Ayden clicked on the update button; however, the system restricted the update and displayed a message stating that the update could only be performed by authorized personnel. This means that his company's laptop has an antivirus mechanism that is actively running and cannot be disabled or altered by users, which demonstrates PCI-DSS requirement no 5.3.

A startup firm contains various devices connected to a wireless network across the floor. An AP with Internet connectivity is placed in a corner to allow wireless communication between devices. To support new devices connected to the network beyond the APS range, an administrator used a network device that extended the signals of the wireless AP and transmitted it to uncovered area, identify the network component employed by the administrator to extend signals in this scenario.
A. wireless modem
B. Wireless bridge
C. Wireless repeater
D. Wireless router
答案：C
解題說明：
Wireless repeater is the network component employed by the administrator to extend signals in this scenario. A wireless network is a type of network that uses radio waves or infrared signals to transmit data between devices without using cables or wires. A wireless network can consist of various components, such as wireless access points (APs), wireless routers, wireless adapters, wireless bridges, wireless repeaters, etc. A wireless repeater is a network component that extends the range or coverage of a wireless signal by receiving it from an AP or another repeater and retransmitting it to another area . A wireless repeater can be used to support new devices connected to the network beyond the AP's range . In the scenario, a startup firm contains various devices connected to a wireless network across the floor. An AP with internet connectivity is placed in a corner to allow wireless communication between devices. To support new devices connected to the network beyond the AP's range, an administrator used a network component that extended the signals of the wireless AP and transmitted it to the uncovered area. This means that he used a wireless repeater for this purpose. A wireless bridge is a network component that connects two or more wired or wireless networks or segments together . A wireless bridge can be used to expand the network or share resources between networks . A wireless modem is a network component that modulates and demodulates wireless signals to enable data transmission over a network . A wireless modem can be used to provide internet access to devices via a cellular network or a satellite network . A wireless router is a network component that performs the functions of both a wireless AP and a router . A wireless router can be used to create a wireless network and connect it to another network, such as the internet
問題 #46
Warren, a member of IH&R team at an organization, was tasked with handling a malware attack launched on one of servers connected to the organization's network. He immediately implemented appropriate measures to stop the infection from spreading to other organizational assets and to prevent further damage to the organization.
Identify the IH&R step performed by Warren in the above scenario.
A. Recovery
B. Eradication
C. Containment
D. Incident triage
答案：C
解題說明：
Containment is the IH&R step performed by Warren in the above scenario. IH&R (Incident Handling and Response) is a process that involves identifying, analyzing, containing, eradicating, recovering from, and reporting on security incidents that affect an organization's network or system. Containment is the IH&R step that involves implementing appropriate measures to stop the infection from spreading to other organizational assets and to prevent further damage to the organization . Containment can be done by isolating the affected system or network, blocking malicious traffic or communication, disabling or removing malicious accounts or processes, etc. Recovery is the IH&R step that involves restoring the normal operation of the system or network after eradicating the incident. Eradication is the IH&R step that involves removing all traces of the incident from the system or network, such as malware, backdoors, compromised files, etc. Incident triage is the IH&R step that involves prioritizing incidents based on their severity, impact, and urgency.
