Q2. In Trojan terminology, what is a covert channel?
A. A channel that transfers information within a computer system or network in a way that violates the security policy
B. A legitimate communication path within a computer system or network for transfer of data
C. It is a kernel operation that hides boot processes and services to mask detection

Q3. Peter has been monitoring his IDS and sees that there are a huge number of ICMP Echo Reply packets that are being received on the External Gateway interface. Further inspection reveals they are not responses from internal hosts request but simply responses coming from the Internet. What could be the likely cause of this?
A. Someone Spoofed Peter’s IP Address while doing a land attack
B. Someone Spoofed Peter’s IP Address while doing a DoS attack
C. Someone Spoofed Peter’s IP Address while doing a smurf Attack
D. Someone Spoofed Peter’s IP address while doing a fraggle attack
Answer: C
Explanation: An attacker sends forged ICMP echo packets to broadcast addresses of vulnerable networks with forged source address pointing to the target (victim) of the attack. All the systems on these networks reply to the victim with ICMP echo replies. This rapidly exhausts the bandwidth available to the target.
Q4. Sandra is the security administrator of ABC.com. One day she notices that the ABC.com Oracle database server has been compromised and customer information along with financial data has been stolen. The financial loss will be estimated in millions of dollars if the database gets into the hands of competitors. Sandra wants to report this crime to the law enforcement agencies immediately.
Which organization coordinates computer crime investigations throughout the United States?
A. NDCA
B. NICP
C. CIRP
D. NPC
E. CIA
Answer: D
Q5. Which one of the following is defined as the process of distributing incorrect Internet Protocol (IP) addresses/names with the intent of diverting traffic?
A. Network aliasing
B. Domain Name Server (DNS) poisoning
C. Reverse Address Resolution Protocol (ARP)
D. Port scanning
Answer: B
This reference is close to the one listed DNS poisoning is the correct answer.
This is how DNS DOS attack can occur. If the actual DNS records are unattainable to the attacker for him to alter in this fashion, which they should be, the attacker can insert this data into the cache of there server instead of replacing the actual records, which is referred to as cache poisoning.
Q6. This is an authentication method in which is used to prove that a party knows a password without transmitting the password in any recoverable form over a network. This authentication is secure because the password is never transmitted over the network, even in hashed form; only a random number and an encrypted random number are sent.
A. Realm Authentication
B. SSL Authentication
C. Basic Form Authentication
D. Cryptographic Authentication
E. Challenge/Response Authentication
Answer: E
Explanation: Challenge-Response Authentication The secure Challenge-Response Authentication Mechanism (CRAM-MD5) avoids passing a cleartext password over the network when you access your email account, ensuring that your login details cannot be captured and used by anyone in transit. http://www.neomailbox.com/component/content/article/212-hardware-token-authentication
Q7. There is some dispute between two network administrators at your company. Your boss asks you to come and meet with the administrators to set the record straight. Which of these are true about PKI and encryption?
Select the best answers.
A. PKI provides data with encryption, compression, and restorability.
B. Public-key encryption was invented in 1976 by Whitfield Diffie and Martin Hellman.
C. When it comes to eCommerce, as long as you have authenticity, and authenticity, you do not need encryption.
D. RSA is a type of encryption.
Answer: BD
Explanation: PKI provides confidentiality, integrity, and authenticity of the messages exchanged between these two types of systems. The 3rd party provides the public key and the receiver verifies the message with a combination of the private and public key. Public-key encryption WAS invented in 1976 by Whitfield Diffie and Martin Hellman. The famous hashing algorithm Diffie-Hellman was named after them. The RSA Algorithm is created by the RSA Security company that also has created other widely used encryption algorithms.
Q8. TCP SYN Flood attack uses the three-way handshake mechanism.
1. An attacker at system A sends a SYN packet to victim at system B.
2. System B sends a SYN/ACK packet to victim A.
3. As a normal three-way handshake mechanism system A should send an ACK packet to system B, however, system A does not send an ACK packet to system B. In this case client B is waiting for an ACK packet from client A.
This status of client B is called _________________
A. "half-closed"
B. "half open"
C. "full-open"
D. "xmas-open"
Answer: B
Q9. In order to attack a wireless network, you put up an access point and override the signal of the real access point. As users send authentication data, you are able to capture it. What kind of attack is this?
A. WEP attack
B. Drive by hacking
C. Rogue access point attack
D. Unauthorized access point attack
Answer: C
Explanation: The definition of a Rogue access point is:1. A wireless access point (AP) installed by an employee without the consent of the IT department. Without the proper security configuration, users have exposed their company's network to the outside world.2. An access point (AP) set up by an attacker outside a facility with a wireless network. Also called an "evil twin," the rogue AP picks up beacons (signals that advertise its presence) from the company's legitimate AP and transmits identical beacons, which some client machines inside the building associate with.
Q10. Oregon Corp is fighting a litigation suit with Scamster Inc. Oregon has assigned a private investigative agency to go through garbage, recycled paper, and other rubbish at Scamster's office site in order to find relevant information. What would you call this kind of activity?
A. Garbage Scooping
B. Dumpster Diving
C. Scanning
D. CI Gathering
Answer: B
Explanation: Dumpster diving is the colloquial name for going through somebody's garbage --which will usually be in dumpsters for large organizations. This is a powerful tactic because it is protected by social taboos. Trash is bad, and once it goes into the trash, something is best forgotten. The reality is that most company trash is fairly clean, and provides a gold mine of information.
