Quid pro quo is the social engineering technique that Johnson employed in the above scenario. Social engineering is a technique that involves manipulating or deceiving people into performingactions or revealing information that can be used for malicious purposes. Social engineering can be performed through various methods, such as phone calls, emails, websites, etc. Quid pro quo is a social engineering method that involves offering a service or a benefit in exchange for information or access. Quid pro quo can be used to trick victims into believing that they are receiving help or assistance from a legitimate source, while in fact they are compromising their security or privacy . In the scenario, Johnson performed quid pro quo by claiming himself to represent a technical support team from a vendor and offering to help sibertech.org with a server issue, while in fact he prompted the victim to execute unusual commands and install malicious files, which were then used to collect and pass critical information to Johnson’s machine. Diversion theft is a social engineering method that involves diverting the delivery or shipment of goods or assets to a different location or destination. Elicitation is a social engineering method that involves extracting information from a target by engaging them in a conversation or an interaction. Phishing is a social engineering method that involves sending fraudulent emails or messages that appear to come from a trusted source, such as a bank, a company, or a person, and asking the recipient to click on a link, open an attachment, or provide personal or financial information.

Digital locks are the types of physical locks that Juan installed in this scenario. A physical lock is a device that prevents or restricts access to a physical location or environment, such as a door, a cabinet, a drawer, etc. A physical lock can have different types based on its mechanism or technology. A digital lock is a type of physical lock that uses electronic or digital components, such as a keypad, a card reader, a fingerprint scanner, etc., to unlock or lock . A digital lock can be used to provide enhanced security and convenience to users, but it can also be vulnerable to hacking or tampering. In the scenario, Juan installed a physical lock at the entrance of eachfloor. All employees in the organization were allotted a smart card embedded in their ID cards, which had to be swiped to unlock doors and access any floor. This means that he installed digital locks for those doors. A mechanical lock is a type of physical lock that uses mechanical components, such as a key, a bolt, a latch, etc., to unlock or lock. A combination lock is a type of physical lock that uses a sequence of numbers or symbols, such as a dial, a wheel, or a keypad, to unlock or lock. An electromagnetic lock is a type of physical lock that uses an electromagnet and an armature plate to unlock or lock. 

20.20.10.19 is the source IP address of the SYN flooding attack in the above scenario. SYN flooding is a type of denial-of-service (DoS) attack that exploits the TCP (Transmission Control Protocol) three-way handshake process to disrupt the network and gain advantage over the network to bypass the firewall. SYN flooding sends a large number of SYN packets with spoofed source IP addresses to a target server, causing it to allocate resources and wait for the corresponding ACK packets that never arrive. This exhausts the server’s resources and prevents it from accepting legitimate requests . To determine the source IP address of the SYN flooding attack, one has to follow these steps:

Navigate to the Documents folder of Attacker-1 machine.

Double-click on Synflood.pcapng file to open it with Wireshark.

Click on Statistics menu and select Conversations option.

Click on TCP tab and sort the list by Bytes column in descending order.

Observe the IP address that has sent the most bytes to 20.20.10.26 (target server).

The IP address that has sent the most bytes to 20.20.10.26 is 20.20.10.19 , which is the source IP address of the SYN flooding attack.

The correct answer is C, as it identifies the PCI-DSS requirement followed by Myles in the above scenario. PCI-DSS is a set of standards that aims to protect cardholder data and ensure secure payment transactions. PCI-DSS has 12 requirements that cover various aspects of security such as network configuration, data encryption, access control, vulnerability management, monitoring, and testing. PCI-DSS requirement no 5.1 states that “Protect all systems against malware and regularly update anti-virus software or programs”. In the above scenario, Myles followed this requirement by installing antivirus software on each laptop to detect and protect the machines from external malicious events over the Internet. Option A is incorrect, as it does not identify the PCI-DSS requirement followed by Myles in the above scenario. PCI-DSS requirement no 1.3.2 states that “Do not allow unauthorized outbound traffic from the cardholder data environment to the Internet”. In the above scenario, Myles did not follow this requirement, as there was no mention of outbound traffic or cardholder data environment. Option B is incorrect, as it does not identify the PCI-DSS requirement followed by Myles in the above scenario. PCI-DSS requirement no 1.3.5 states that “Restrict inbound and outboundtraffic to that which is necessary for the cardholder data environment”. In the above scenario, Myles did not follow this requirement, as there was no mention of inbound or outbound traffic or cardholder data environment. Option D is incorrect, as it does not identify the PCI-DSS requirement followed by Myles in the above scenario. PCI-DSS requirement no 1.3.1 states that “Implement a firewall configuration that restricts connections between publicly accessible servers and any system component storing cardholder data”. In the above scenario, Myles did not follow this requirement, as there was no mention of firewall configuration or publicly accessible servers or system components storing cardholder data.

For comprehensive application security testing, combining Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) provides the best coverage:

Static Application Security Testing (SAST):

Source Code Analysis: Scans the source code to identify vulnerabilities such as code injection, buffer overflows, and insecure APIs.

Early Detection: Allows developers to fix vulnerabilities early in the development lifecycle.

Dynamic Application Security Testing (DAST):

Runtime Analysis: Tests the running application for vulnerabilities, including issues related to configuration, authentication, and authorization.

Real-World Attacks: Simulates real-world attacks to identify how the application behaves under different threat scenarios.

Combined Approach:

Holistic Security: Using both SAST and DAST provides a thorough security assessment, covering both code-level and runtime vulnerabilities.

Comprehensive Coverage: Ensures that both internal code issues and external attack vectors are addressed.

Quantum cryptography is the encryption mechanism demonstrated in the above scenario. Quantum cryptography is a branch of cryptography that uses quantum physics to secure data transmission and communication. Quantum cryptography encrypts data by using a sequence of photons that have a spinning trait, called polarization, while traveling from one end to another. These photons keep changing their shapes, called states, during their course through filters: vertical, horizontal, forward slash, and backslash. Quantum cryptography ensures that any attempt to intercept or tamper with the data will alter the quantum states of the photons and be detected by the sender and receiver . Homomorphic encryption is a type of encryption that allows computations to be performed on encrypted data without decrypting it first. Rivest Shamir Adleman (RSA) encryption is a type of asymmetric encryption that uses two keys, public and private, to encrypt and decrypt data. Elliptic curve cryptography (ECC) is a type of asymmetric encryption that uses mathematical curves to generate keys and perform encryption and decryption.

Obfuscating is the technique used by Kevin to evade the IDS system in the above scenario. Obfuscating is a technique that involves encoding or modifying packets or data with various methods or characters to make them unreadable or unrecognizable by an IDS (Intrusion Detection System). Obfuscating can be used to bypass or evade an IDS system that relies on signatures or patterns to detect malicious activities. Obfuscating can include encoding packets with Unicode characters, which are characters that can represent various languages and symbols. The IDS system cannot recognize the packet, but the target web server can decode them and execute them normally. Desynchronization is a technique that involves creating discrepancies or inconsistencies between the state of a connection as seen by an IDS system and the state of a connection as seen by the end hosts. Desynchronization can be used to bypass or evade an IDS system that relies on stateful inspection to track and analyze connections. Desynchronization can include sending packets with invalid sequence numbers, which are numbers that indicate the order of packets in a connection. Session splicing is a technique that involves splitting or dividing packets or data into smaller fragments or segmentsto make them harder to detect by an IDS system. Session splicing can be used to bypass or evade an IDS system that relies on packet size or content to detect malicious activities. Session splicing can include sending packets with small MTU (Maximum Transmission Unit) values, which are values that indicate the maximum size of packets that can be transmitted over a network. An urgency flag is a flag in the TCP (Transmission Control Protocol) header that indicates that the data in the packet is urgent and should be processed immediately by the receiver. An urgency flag is not a technique to evade an IDS system, but it can be used to trigger an IDS system to generate an alert or a response.
