Question 1

What type of attack occurs when the computer originating the attack causes several other computers to send attack packets?
A) Distributed denial of service
B) Dormant denial of service
C) Duplicated denial of service
D) Distributed destruction of service

Accepted Answer

This type of attack is called a distributed denial of service (DDoS) attack. The attacker uses multiple compromised systems to flood the target with traffic, making it unavailable to its intended users.

Question 2

Which of the following information about us should be kept private?
A) Family information
B) Employment information
C) Student information
D) Both a and b
E) a, b, and c

Accepted Answer

All of the options listed (family information, employment information, and student information) may contain personal and sensitive details that could be used against us if accessed by the wrong people. It is important to protect our privacy and limit the information we share, especially online or with individuals we do not know or trust.

Question 4

The traceroute troubleshooting utility can be used by which of the following operating systems?
A) UNIX
B) Mac OS
C) Netware
D) Windows
E) All of the above

Accepted Answer

Traceroute is a network diagnostic tool used to track the pathway that a packet of information takes from one computer to another. It is available on various operating systems, including UNIX, Mac OS, Netware, and Windows, making it a versatile tool for identifying network issues across different platforms.

Question 5

_____ can translate an IP address from a private network to a different address used on a public network or the Internet.
A) Routers
B) Proxy servers
C) Network address translation
D) Packet filters

Accepted Answer

Network address translation (NAT) can translate an IP address from a private network to a different address used on a public network or the Internet. Routers and packet filters can also perform some network address translation functions but they do not offer the same level of flexibility and control as dedicated NAT devices. Proxy servers are used to cache web content and improve performance but are not typically used for network address translation.

Question 6

Which of the following is part of the total cost of ownership of a computer network?
A) Hardware
B) Software
C) User support costs
D) Maintenance
E) All of the above

Accepted Answer

Question 8

A _ ____ is software or hardware placed between two or more networks that selectively allows or denies access.
A) gateway
B) filter
C) firewall
D) DMZ

Accepted Answer

A firewall is the correct term for software or hardware that selectively allows or denies access between networks. Gateways can sometimes serve a similar function but are more often used to connect different types of networks. Filters can also be used to restrict access, but they do not provide the same level of control as a firewall. A DMZ (demilitarized zone) is a separate network that sits between the internet and an organization's internal network, and while it can incorporate firewall technology, it is not itself a firewall.

Question 9

Operating system and network security is the ability to do which of the following reliably to information?
A) Store
B) Modify
C) Protect
D) Grant access to
E) All of the above

Accepted Answer

Operating system and network security encompasses the ability to store, modify, protect, and grant access to information reliably, ensuring the integrity, confidentiality, and availability of data.

Question 10

A) 50
B) 65
C) 80
D) 90

Accepted Answer

The answer of According to a recent survey performed by...

Question 11

What type of attack has occurred when a logged-on computer is used when that person is not present?
A) Spoofing
B) Denial of service
C) Buffer
D) Standalone workstation

Accepted Answer

A standalone workstation is a computer that is not connected to a network. Therefore, it cannot be used to launch an attack on another computer.

Question 12

Statistics from the CSI suggest that the number of people working as computer security professionals has been increasing by _____ percent a year since 1998.
A) 30
B) 50
C) 75
D) 100

Accepted Answer

The answer of Statistics from the CSI suggest that the...

Question 13

A _____ attack is used to interfere with normal access to a network host, Web site, or service, by flooding a network with useless information or with frames or packets containing errors that are not identified by a particular network service.
A) virus
B) buffer
C) denial of service
D) port scanning

Accepted Answer

A denial of service (DoS) attack floods a network with useless information or with frames or packets containing errors that are not identified by a particular network service. This effectively makes the network or service unavailable to legitimate users, hence the term "denial of service." A virus and buffer are not specific to this type of attack, and port scanning is used to identify open ports on a system or network, not to interfere with access.

Question 14

Which of the following is a reason for the failure to fully use the security features of an operating system or network?
A) Lack of time
B) Inadequate training or knowledge of the features
C) A history of doing things only in a specific way
D) All of the above

Accepted Answer

The answer of Which of the following is a reason...

Question 15

The _____ translates information from the kernel and device drivers so the application can use it.
A) RPC
B) API
C) BIOS
D) resource manager

Accepted Answer

Application Programming Interface (API) is the interface that allows applications to communicate with the operating system. It translates information from the kernel and device drivers so that the application can use it.

Question 16

Which of the following is a cost of deploying security within an organization?
A) Testing security systems
B) Training users
C) Training consultants
D) Both a and b
E) Both a and c

Accepted Answer

Testing security systems and training users are both costs associated with deploying security within an organization. While training consultants is important for maintaining security, it is not specifically a cost associated with deployment. Therefore, options A and B are the best choices.

Question 17

At a minimum, how many groups does training involve within an organization?
A) 1
B) 2
C) 3
D) 4

Accepted Answer

Training within an organization involves at least two groups - the trainers/instructors and the trainees.

Question 18

What type of attack has occurred when an attacker gains access to a computer through the use of a hidden program?
A) Trojan horse
B) Buffer
C) Worm
D) Source routing

Accepted Answer

A hidden program is typically associated with a Trojan horse attack, which involves tricking the user into downloading and installing the program, often disguised as a legitimate file or software update. Once installed, the attacker gains unauthorized access to the computer.

Question 19

_____ consists of a chain of activities that is necessary to complete a task, such as filling out and transmitting forms, entering data, updating databases, and creating new files.
A) Ensuring privacy
B) Workflow
C) Protecting information
D) Compensating for human error

Accepted Answer

This describes the process of workflow, which involves a series of sequential steps needed to complete a task or project. The other options (ensuring privacy, protecting information, and compensating for human error) are important considerations in various aspects of information management, but they do not directly relate to the concept of workflow.

Question 20

In a source routing attack, the attacker modifies the _____ and routing information to make a packet appear to come from a different source, such as one that is already trusted for communications on a network.
A) destination address
B) source address
C) destination header
D) source data

Accepted Answer

In a source routing attack, the attacker modifies the source address of a packet to make it appear as if it comes from a trusted source. By doing so, the attacker can bypass security measures and gain unauthorized access to a network. Modifying the destination address or header is not a part of source routing attack. Source data may be modified, but it is not the primary target of a source routing attack.
