True or False?

An employee does something as a company representative with the knowledge of that company and this action is deemed illegal. The company would be legally responsible for this action.

true

false

Explanation:

This is a bit of a grey area and would also depend on local laws. In many cases, if the employee did something with the knowledge or approval of the company, then the legal responsibility would probably be with the company not the employee. In some areas or situations, both the company and employee could be held legally responsible.

When describing malware, what is a difference between a virus and a worm?

ITC Final Exam Answers 004

A virus focuses on gaining privileged access to a device, whereas a worm does not.
A virus can be used to deliver advertisements without user consent, whereas a worm cannot.
A virus replicates itself by attaching to another file, whereas a worm can replicate itself independently.

A virus can be used to launch a DoS attack (but not a DDoS), but a worm can be used to launch both DoS and DDoS attacks.

Explanation:

Malware can be classified as follows:

– Virus (self replicates by attaching to another program or file)
– Worm (replicates independently of another program)
– Trojan Horse (masquerades as a legitimate file or program)
– Rootkit (gains privileged access to a machine while concealing itself)
– Spyware (collects information from a target system)
– Adware (delivers advertisements with or without consent)
– Bot (waits for commands from the hacker)
– Ransomware (holds a computer system or data captive until payment is received)

What type of attack uses zombies?
- Trojan horse
- DDoS
- SEO poisoning
- spear phishing
  
  Explanation:
  
  The hacker infects multiple machines (zombies), creating a botnet. Zombies launch the distributed denial of service (DDoS) attack.

The IT department is reporting that a company web server is receiving an abnormally high number of web page requests from different locations simultaneously. Which type of security attack is occurring?

adware
DDoS
phishing
social engineering

spyware

Explanation:

Phishing, spyware, and social engineering are security attacks that collect network and user information. Adware consists, typically, of annoying popup windows. Unlike a DDoS attack, none of these attacks generate large amounts of data traffic that can restrict access to network services.

patient records
first and last name
contact information

next appointment

Explanation:

An email message is transmitted in plain text and can be read by anyone who has access to the data while it is en route to a destination. Patient records include confidential or sensitive information that should be transmitted in a secure manner.

Which two tools used for incident detection can be used to detect anomalous behavior, to detect command and control traffic, and to detect infected hosts? (Choose two.)

intrusion detection system
Honeypot
NetFlow
Nmap

a reverse proxy server

Explanation:

Although each of these tools is useful for securing networks and detecting vulnerabilities, only an IDS and NetFlow logging can be used to detect anomalous behavior, command and control traffic, and infected hosts.

For what purpose would a network administrator use the Nmap tool?

detection and identification of open ports
protection of the private IP addresses of internal hosts
identification of specific network anomalies

collection and analysis of security alerts and logs

Explanation:

Nmap allows an administrator to perform port scanning to probe computers and the network for open ports. This helps the administrator verify that network security policies are in place.

Which stage of the kill chain used by attackers focuses on the identification and selection of targets?
- delivery
- exploitation
- weaponization
- reconnaissance
  
  Explanation:
  
  It is the first stage, reconnaissance, of the the kill chain that focuses on the identification and selection of targets.

What is an example of the a Cyber Kill Chain?

a group of botnets
a planned process of cyberattack
a series of worms based on the same core code

a combination of virus, worm, and Trojan Horse

Explanation:

The Cyber Kill Chain describes the phases of a progressive cyberattack operation. The phases include the following:
Reconnaissance
Weaponization
Delivery
Exploitation
Installation
Command and control
Actions on objectives
