NEW QUESTION # 137
Which of the following honeypots provides an attacker access to the real operating system without any
restriction and collects a vast amount of information about the attacker?
- A. Honeyd
- B. Medium-interaction honeypot
- C. High-interaction honeypot
- D. Low-interaction honeypot
Answer: C
Explanation:
A high-interaction honeypot offers a vast amount of information about attackers. It provides an attacker access
to the real operating system without any restriction. A high-interaction honeypot is a powerful weapon that
provides opportunities to discover new tools, to identify new vulnerabilities in the operating system, and to learn
how blackhats communicate with one another.
Answer option D is incorrect. A low-interaction honeypot captures limited amounts of information that are
mainly transactional data and some limited interactive information. Because of simple design and basic
functionality, low-interaction honeypots are easy to install, deploy, maintain, and configure. A low-interaction
honeypot detects unauthorized scans or unauthorized connection attempts. A low-interaction honeypot is like a
one-way connection, as the honeypot provides services that are limited to listening ports. Its role is very
passive and does not alter any traffic. It generates logs or alerts when incoming packets match their patterns.
Answer option B is incorrect. A medium-interaction honeypot offers richer interaction capabilities than a low-
interaction honeypot, but does not provide any real underlying operating system target. Installing and
configuring a medium-interaction honeypot takes more time than a low-interaction honeypot. It is also more
complicated to deploy and maintain as compared to a low-interaction honeypot. A medium-interaction honeypot
captures a greater amount of information but comes with greater risk. Answer option C is incorrect. Honeyd is
an example of a low-interaction honeypot.
NEW QUESTION # 138
Which BC/DR activity includes action taken toward resuming all services that are dependent on business-critical applications?
- A. Restoration
- B. Resumption
- C. Response
- D. Recovery
Answer: B
Explanation:
In the context of Business Continuity/Disaster Recovery (BC/DR), the activity that includes actions taken toward resuming all services that are dependent on business-critical applications is referred to as Resumption. This phase focuses on the steps necessary to bring critical functions back into operation after a disruption. Recovery, on the other hand, is more about the actions taken to return the business to normal operating conditions post-disaster, which may include repairs, restorations, and return to normalcy. Response is the immediate reaction to an incident, and Restoration is the process of rebuilding or restoring IT systems and operations. Reference: The information aligns with the objectives and documents of the EC-Council's Certified Network Defender (CND) program, which emphasizes understanding and implementing proper BC/DR activities.

NEW QUESTION # 143
Sam wants to implement a network-based IDS in the network. Sam finds out the one IDS solution which works is based on patterns matching. Which type of network-based IDS is Sam implementing?
- A. Stateful protocol analysis
- B. Behavior-based IDS
- C. Signature-based IDS
- D. Anomaly-based IDS
Answer: C
Explanation:
Sam is implementing a Signature-based Intrusion Detection System (IDS). This type of IDS uses predefined patterns of traffic, known as signatures, to identify and flag potential security threats. These signatures are based on known attack patterns and anomalies that have been identified from past incidents. When network traffic matches a signature within the IDS, an alert is generated, indicating a possible security event or breach.
Signature-based IDS is effective in detecting known threats but may not be as effective in identifying new, previously unknown attacks.
References: The information aligns with the Certified Network Defender (CND) objectives and documents, which describe the role and function of signature-based IDS within network security. The CND training materials emphasize the importance of understanding various IDS types, including signature-based systems, which are critical for detecting known threats and maintaining network security1.

NEW QUESTION # 147
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 application layer (single encryption key).
- C. Encryption is performed at the network layer (layer 1 encryption).
- D. No encryption is applied.
Answer: B
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.

The network administrator wants to strengthen physical security in the organization. Specifically, to implement a solution stopping people from entering certain restricted zones without proper credentials.
Which of following physical security measures should the administrator use?
- A. Video surveillance
- B. Mantrap
- C. Bollards
- D. Fence
Answer: B
Explanation:
A mantrap is a physical security mechanism designed to control access to a secure area through a small space that can only fit one person. It typically consists of two sets of interlocking doors. The first set of doors must close before the second set opens, effectively trapping the individual temporarily. This allows security personnel to verify the person's credentials before granting them access to the restricted zone. Mantraps are particularly effective in sensitive areas where strict access control is required.
References: The concept of a mantrap as a physical security measure is discussed in various security frameworks and guidelines. It is a recognized method for strengthening physical security by controlling individual access to secure areas, as outlined in security best practices and standards123.

John wants to implement a firewall service that works at the session layer of the OSI model. The firewall must also have the ability to hide the private network information. Which type of firewall service is John thinking of implementing?
- A. Stateful Multilayer Inspection
- B. Application level gateway
- C. Packet Filtering
- D. Circuit level gateway
Answer: D
Explanation:
A circuit level gateway is a type of firewall that operates at the session layer of the OSI model, which is Layer 5. This kind of firewall is designed to provide security by validating and managing sessions without inspecting the actual contents of each packet. It is particularly adept at hiding the private network information because it only allows traffic through that is part of an established session, effectively masking the details of the network's internal structure from the outside. This makes it an ideal choice for John's requirements.
