What type of an attack can disable a computer by forcing it to use memory or by overworking its CPU?

• APT
  Refer to Chapter 1 - Slides 24 - Threat Complexity

  Advanced persistent threat (APT) is a continuous computer hack that occurs under the radar against a specific object. Criminals usually choose an APT for business or political motives.

• algorithm
  Refer to curriculum topic: 1.4.2

  Algorithm attacks can force computers to use memory or overwork the CPU.

• DDoS
  Refer to Chapter 1 - Slides 25 - Threat Complexity

  Next generation 911 call centers are vulnerable because they use Voice-over-IP (VoIP) systems rather than traditional landlines. In addition to TDoS attacks, these call centers can also be at risk of distributed-denial-of-service (DDoS) attacks that use many systems to flood the resources of the target making the target unavailable to legitimate users

• exhaustion

What does the term vulnerability mean?

• a known target or victim machine

• a method of attack to exploit a target

• a potential threat that a hacker creates

• a weakness that makes a target susceptible to an attack

Answer explanation

Vulnerability refers to a weakness that makes a target susceptible to an attack.

Refer to curriculum topic: 1.3.1

A vulnerability is not a threat, but it is a weakness that makes the PC or the software a target for attacks.

What type of attack uses many systems to flood the resources of a target, thus making the target unavailable?

• DoS

• spoof

• DDoS

• ping sweep

Answer explanation

DDoS attack uses many systems to flood the resources of a target, making it unavailable. It is a type of DoS attack.

Refer to curriculum topic: 1.4.2

DDoS is is an attack that involves multiple systems. DoS involves only a single attack system.

Match the following and name 1 types of records that cyber criminals would be interested in stealing from organizations.

Refer to Chapter 1 - Slides 14 Common Threats - Threat Arenas

(a)  

Thwarting cyber criminals includes which of the following? (Choose two.)

• hiring hackers

• changing operating systems

• establishing early warning systems

• sharing cyber Intelligence information

Answer explanation

Thwarting cyber criminals involves establishing early warning systems and sharing cyber intelligence information. These measures help detect and prevent cyber attacks effectively.

Refer to Chapter 1 - Slides 10 Cybersecurity Specialists

Thwarting the cyber criminals is a difficult task and there is no such thing as a “silver bullet.” However, company, government and international organizations have begun to take coordinated actions to limit or fend off cyber criminals. The coordinated actions include:

1) Vulnerability Database

2) Early Warning Systems

3) Share Cyber Intelligence

4) ISM Standards

5) New Laws

What name is given to hackers who hack for a cause?

Refer to Chapter 1 - Slides 8 Cybersecurity Criminals (Cont.)

Grey hat hackers who rally and protest against different political and social ideas.
Agents publicly protest against organizations or governments by posting articles, videos, leaking sensitive information, and performing distributed denial of service (DDoS) attacks.

(a)  

What name is given to a amateur hacker?

Refer to curriculum topic: 1.2.1

The answer is a term used to describe inexperienced hackers.

What is the workforce framework category that includes highly specialized review and evaluation of incoming cybersecurity information to determine if it is useful for intelligence?

• Analyze

• Securely Provision

• Protect and Defend

• Oversight and Development

Answer explanation

The workforce framework category that includes highly specialized review and evaluation of incoming cybersecurity information to determine if it is useful for intelligence is 'Analyze'.

Refer to Chapter 1 - Slides 28 - A Workforce Framework for Cybersecurity (Cont.)

The Workforce Framework categorizes cybersecurity work into seven categories.

1) Operate and Maintain

2) Protect and Defend includes the identification, analysis, and mitigation of threats to internal systems and networks.

3) Investigate

4) Collect and Operate

5) Analyze includes highly specialized review and evaluation of incoming cybersecurity information to determine if it is useful for intelligence.

6) Oversight and Development provides for leadership, management, and direction to conduct cybersecurity work effectively.

7) Securely Provision includes conceptualizing, designing, and building secure IT systems.
