A2 Computer Network-based Threats

What is "achieved either through the placement of a monitoring device informally known as a bug on the wire in question or through built-in mechanisms in other communication technologies?"

• Wiretapping

• Port Scanning

• Idle Scanning

What is "is a method of determining which ports on a network are open and could be receiving or sending data?"

• Wiretapping

• Port Scanning

• Idle Scanning

What is "a TCP port scan method that consists of sending spoofed packets to a computer to find out what services are available. This is accomplished by impersonating another computer whose network traffic is very slow or nonexistent (that is, not transmitting or receiving information)?"

• Wiretapping

• Port Scanning

• Idle Scanning

What "is an attack meant to shut down a machine or network, making it inaccessible to its intended users?"

• Denial-of-Service

• Spoofing

• Man in the Middle

• Address Resolution Protocol (ARP) Poisoning

What "is a situation in which a person or program successfully identifies as another by falsifying data, to gain an illegitimate advantage?"

• Denial-of-Service

• Spoofing

• Man in the Middle

• Address Resolution Protocol (ARP) Poisoning

What "is a cyberattack where the attacker secretly relays and possibly alters the communications between two parties who believe that they are directly communicating with each other, as the attacker has inserted themselves between the two parties?"

• Denial-of-Service

• Spoofing

• Man in the Middle

• Address Resolution Protocol (ARP) Poisoning

What "is a type of cyber attack carried out over a Local Area Network (LAN) that involves sending malicious packets to a default gateway on a LAN in order to change the pairings in its IP to MAC address table?"

• Denial-of-Service

• Spoofing

• Man in the Middle

• Address Resolution Protocol (ARP) Poisoning

What "is a form of DDoS attack that overloads network resources by broadcasting ICMP echo requests to devices across the network. Devices that receive the request respond with echo replies, which creates a botnet situation that generates a high ICMP traffic rate?"

• Smurf Attack

• Buffer Overflow

• Structured Query Language (SQL) Injection

• Format String Attack

What "occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program attempting to write the data to the buffer overwrites adjacent memory locations?"

• Smurf Attack

• Buffer Overflow

• Structured Query Language (SQL) Injection

• Format String Attack

What "is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database? It generally allows an attacker to view data that they are not normally able to retrieve."

• Smurf Attack

• Buffer Overflow

• Structured Query Language (SQL) Injection

• Format String Attack
