Phishing = An attempt to steal sensitive financial or personal information through fraudulent email or instant messages.
Match the security threat cause with its example:
Physical Cause = Someone stealing a computer that contains vital data. Non-Physical Cause = A virus attack. Virus Attack = A virus replicates and executes itself, usually doing damage to your computer in the process. Online Predator Attack = Compromising credit card information, locking you out of your data, and stealing your identity.

Spyware Threats = Programs that monitor online activities or install programs without consent for profit or to capture personal information. Hackers and Predators = Programmers who victimize others by breaking into computer systems for malicious purposes. Phishing = Attempts to steal sensitive financial or personal information through fraudulent communication.
Match the type of security threat with its characteristic impact:
Computer Viruses = Replicates and executes itself, causing damage to the computer system. Spyware Threats = Monitors online activities or installs programs without consent for profit or to capture personal information. Hackers and Predators = Can compromise credit card information, lock you out of your data, and steal your identity. Phishing = Attempts to steal sensitive financial or personal information through fraudulent communication.
Study Notes
Computer Security Threats
- A malicious program written to alter a computer's operation without the user's permission or knowledge is called a malware.
- Spyware is a type of program that monitors online activities or installs programs without consent for profit or to capture personal information.
- Hackers and predators are individuals who exploit computer security threats to gain unauthorized access to systems or steal sensitive information.
Phishing and Identity Theft
- The goal of phishers is to trick users into revealing sensitive information, such as passwords or credit card numbers, to steal their identity or commit fraud.
- Ransomware is a type of threat that can compromise credit card information, lock users out of their data, and steal their identity.
Access Control and Ports
- A backdoor is a potential attack from a hacker that can allow them to gain unauthorized access to a computer system.
- TCP (Transmission Control Protocol) is a protocol that ensures data arrives in the same order it was sent, making it suitable for applications like web browsing and email.
- UDP (User Datagram Protocol) is a protocol that differs from TCP in that it does not guarantee the order of data arrival, making it suitable for real-time applications.
- Open ports on the Internet allow for communication between devices and are a potential entry point for hackers.
- Trojans are a type of malware that typically gets hidden as a legitimate program.
Protocols and Ports
- UDP is a connectionless protocol, making it suitable for real-time applications.
- TCP is a connection-oriented protocol, ensuring that data arrives in the same order it was sent.
- IP addresses contain two kinds of ports: TCP ports and UDP ports.
Malware and Programming Languages
- Malware can be hidden within legitimate software using a technique called code injection.
- Java is a programming language primarily used for developing web applications and mobile apps.
- C++ is a programming language primarily used for developing operating systems and games.
Matching Characteristics
- TCP is a protocol that ensures data arrives in the same order it was sent, making it suitable for applications like web browsing and email.
- UDP is a protocol that differs from TCP in that it does not guarantee the order of data arrival, making it suitable for real-time applications.
- Ransomware is a type of malware that can compromise credit card information, lock users out of their data, and steal their identity.
- Phishing is a computer security threat that involves tricking users into revealing sensitive information.
- Backdoor is a potential attack from a hacker that can allow them to gain unauthorized access to a computer system.
