Important Eccouncil 212-82 Exam Questions

Answer: A

Explanation:

Hardware-assisted virtualization is a virtualization approach in which the guest OS will not be aware that it is running in a virtualized environment. The virtual machine manager (VMM) will directly interact with the computer hardware, translate commands to binary instructions, and forward them to the host OS.Hardware-assisted virtualization relies on special hardware features in the CPU and chipset to create and manage virtual machines efficiently and securely34.Full virtualization is a virtualization approach in which the guest OS will not be aware that it is running in a virtualized environment, but the VMM will run in software and emulate all the hardware resources for each virtual machine5.Hybrid virtualization is a virtualization approach that combines hardware-assisted and full virtualization techniques to optimize performance and compatibility6.OS-assisted virtualization is a virtualization approach in which the guest OS will be modified to run in a virtualized environment and cooperate with the VMM to access the hardware resources

Answer: A

Explanation:

Stuxnet is the malware signature of the suspicious file in the above scenario. Malware is malicious software that can harm or compromise the security or functionality of a system or network. Malware can include various types, such as viruses, worms, trojans, ransomware, spyware, etc. Malware signature is a unique pattern or characteristic that identifies a specific malware or malware family. Malware signature can be used to detect or analyze malware by comparing it with known malware signatures in databases or repositories. To analyze the suspicious file and identify the malware signature, one has to follow these steps:

Navigate to Documents folder of Attacker Machine-1.

Right-click on security_update.exe file and select Scan with VirusTotal option.

Wait for VirusTotal to scan the file and display the results.

Observe the detection ratio and details.

The detection ratio is 59/70, which means that 59 out of 70 antivirus engines detected the file as malicious. The details show that most antivirus engines detected the file as Stuxnet, which is a malware signature of a worm that targets industrial control systems (ICS). Stuxnet can be used to sabotage or damage ICS by modifying their code or behavior. Therefore, Stuxnet is the malware signature of the suspicious file. KLEZ is a malware signature of a worm that spreads via email and network shares. KLEZ can be used to infect or overwrite files, disable antivirus software, or display fake messages. ZEUS is a malware signature of a trojan that targets banking and financial systems. ZEUS can be used to steal or modify banking credentials, perform fraudulent transactions, or install other malware. Conficker is a malware signature of a worm that exploits a vulnerability in Windows operating systems. Conficker can be used to create a botnet, disable security services, or download other malware

Answer: B

RFID (Radio Frequency Identification) is the wireless technology that the software company has implemented in the above scenario.RFID uses radio-frequency electromagnetic waves to transfer data for automatic identification and for tracking tags attached to objects1112.WiMAX (Worldwide Interoperability for Microwave Access) is a wireless technology that provides high-speed broadband access over long distances13.Bluetooth is a wireless technology that enables short-range data communication between devices, such as phones, laptops, printers, etc.14.Wi-Fi (Wireless Fidelity) is a wireless technology that allows devices to connect to a local area network or the internet using radio waves

Answer: B

Explanation:

Masking is the technique that Andre employed in the above scenario. Masking is a deidentification technique that can replace the critical information in database fields with special characters such as asterisks (*) and hashes (#). Masking can help protect sensitive data from unauthorized access or disclosure, while preserving the format and structure of the original data . Tokenization is a deidentification technique that can replace the critical information in database fields with random tokens that have no meaning or relation to the original data. Hashing is a deidentification technique that can transform the critical information in database fields into fixed-length strings using a mathematical function. Bucketing is a deidentification technique that can group the critical information in database fields into ranges or categories based on certain criteria.

Answer: B

Explanation:

A circuit-level gateway is a type of firewall that works at the session layer of the OSI model and monitors the TCP handshake between hosts to determine whether a requested session is legitimate.It does not inspect the contents of each packet, but rather relies on the session information to filter traffic
