Which type of wireless network attack is characterized by an attacker using a high gain amplifier from a nearby location to drown out the legitimate access point signal?
- A. Jamming signal attack
- B. Ad Hoc Connection attack
- C. Rogue access point attack
- D. Unauthorized association
Answer: A
Explanation:
The type of wireless network attack characterized by an attacker using a high gain amplifier to drown out the legitimate access point signal is known as a jamming signal attack. This attack involves the deliberate transmission of radio signals at the same frequency as the access point, thereby overwhelming and interfering with the legitimate signal. High gain amplifiers can be used to increase the strength of the jamming signal, making it more effective at disrupting the wireless communication.
References: This explanation is consistent with general network security knowledge regarding the behavior of wireless signals and the impact of amplification on signal strength and interference. While specific references to the EC-Council's Certified Network Defender (CND) course materials cannot be provided here, the information aligns with the principles of wireless network attacks and defense strategies.

NEW QUESTION # 78
Adam, a malicious hacker, has just succeeded in stealing a secure cookie via a XSS attack. He is able to replay the cookie even while the session is valid on the server. Which of the following is the most likely reason of this cause?
- A. Two way encryption is applied.
- B. Encryption is performed at the network layer (layer 1 encryption).
- C. Encryption is performed at the application layer (single encryption key).
- D. No encryption is applied.
Answer: C
Explanation:
Single key encryption uses a single word or phrase as the key. The same key is used by the sender to encrypt and the receiver to decrypt. Sender and receiver initially need to have a secure way of passing the key from one to the other. With TLS or SSL this would not be possible. Symmetric encryption is a type of encryption that uses a single key to encrypt and decrypt data. Symmetric encryption algorithms are faster than public key encryption. Therefore, it is commonly used when a message sender needs to encrypt a large amount of data.
Data Encryption Standard (DES) uses the symmetric encryption key algorithm to encrypt data.

- C. AES-GCMP 256
- D. RC4.TKIP
Answer: C
Explanation:
WPA5 is not a standard term used in the industry, and there seems to be a confusion or typo in the question.
However, based on the context of Wi-Fi security and encryption, the closest relevant standard is WPA3, which uses AES-GCMP 256 as its encryption algorithm. WPA3 is the successor to WPA2 and provides enhanced security features. It uses the Advanced Encryption Standard (AES) with Galois/Counter Mode Protocol (GCMP) 256-bit encryption, which offers a higher level of security than the previous encryption methods used in WPA2, such as AES-CCMP. AES-GCMP 256 provides robust protection against various attacks and is designed to work efficiently on a wide range of devices, including those with limited processing capabilities.
References: The information provided is based on the current understanding of Wi-Fi security protocols, specifically the WPA3 standard, which is known to use AES-GCMP 256-bit encryption123.
NEW QUESTION # 85
Rick has implemented several firewalls and IDS systems across his enterprise network. What should he do to effectively correlate all incidents that pass through these security controls?
- A. Implement IPsec
- B. Use Network Time Protocol (NTP)
- C. Implement Simple Network Management Protocol (SNMP)
- D. Use firewalls in Network Address Transition (NAT) mode
Answer: B
Explanation:
To effectively correlate incidents across various security controls like firewalls and IDS systems, it is essential to ensure that the timestamps of logs and events are synchronized. This is where Network Time Protocol (NTP) comes into play. NTP ensures that all devices on the network are on the same time setting, which is crucial for event correlation. Without synchronized time settings, it would be challenging to establish a timeline of events and understand the sequence in which they occurred, making incident response and forensic analysis more difficult.
References: The importance of using NTP for incident correlation is well-documented in network security best practices and is also highlighted in the EC-Council's Certified Network Defender (CND) course materials. The CND course emphasizes the role of NTP in maintaining accurate time stamps across network devices for effective security incident management and analysis.

NEW QUESTION # 87
Blake is working on the company's updated disaster and business continuity plan. The last section of the plan covers computer and data incidence response. Blake is outlining the level of severity for each type of incident in the plan. Unsuccessful scans and probes are at what severity level?
- A. High severity level
- B. Extreme severity level
- C. Low severity level
- D. Mid severity level
Answer: C
Explanation:
In the context of incident response, unsuccessful scans and probes are typically considered a low severity level. This is because they often indicate an attempted reconnaissance or mapping of systems rather than a successful compromise or disruption of services. While they should be monitored and analyzed to improve defenses and detect patterns of malicious activity, they do not usually signify an immediate threat to the integrity, availability, or confidentiality of systems.
References: The classification of unsuccessful scans and probes as low severity is consistent with standard practices in incident response and is supported by various cybersecurity frameworks and guidelines, including those from the EC-Council's Certified Network Defender (CND) program.
