Network and Distributed Systems Security: Chapter 9

Which network communication medium is most susceptible to physical wiretapping?

How does 'inductance' facilitate wiretapping in certain network transmission media?

Which of the following best describes a 'sequencing attack' on network communications?

Why is wireless communication inherently more vulnerable than wired communication?

What is the primary purpose of a 'Key Distribution Center (KDC)' in the Kerberos authentication protocol?

In the context of network security, what is a 'replay attack', and how can it be mitigated?

A company uses optical fiber for its network backbone. What is a potential vulnerability related to wiretapping that they should be aware of?

Which of the following is a key characteristic of a Distributed Denial of Service (DDoS) attack?

How does a SYN flood attack lead to a denial-of-service?

What is the primary difference between 'link encryption' and 'end-to-end encryption' in network security?

What is the significance of a MAC address in network communication, and how might it be exploited?

An attacker replays an innocent image to security cameras, gaining unmonitored access to a bank vault. What type of attack is this?

How does a 'Smurf attack' amplify the impact of a denial-of-service attack?

What are the two main concerns regarding authentication issues in a distributed system?

What is the role of 'ports' in addressing and routing network traffic?

What is the general definition of a network?

What is the purpose of Wireshark?

Which of the following statements best describes the concept of 'anonymity' as a network security issue?

Which of the following is NOT a security function of Kerberos?

A key feature of a network is that it always involves only a single server interacting with one client.

In network communications, the vulnerability of data diminishes when transmitted wirelessly compared to using a physical wire.

In cable networks, wires prevent signals from radiating, effectively eliminating the risk of eavesdropping.

Optical fibers are highly vulnerable to tapping due to the electrical nature of their signal transmission.

The footprint of a microwave broadcast is intentionally narrow in order to improve security.

Data emanation is a key strength of wired networks, ensuring reliable signal transmission.

Routing and addressing protocols are not typically considered vulnerabilities in network security.

A network interface card (NIC) has a unique physical MAC address.

In a sequencing attack, the attacker manipulates data values by inserting them into a stream.

Eavesdropping and wiretapping on a network represent modification threats to communication.

In a 'Smurf attack', the attacker hides their address when sending ping packets.

In a SYN flood attack, the attacker aims to exhaust the victim's resources by overflowing a queue of complete connections.

DDoS attacks are generally launched by a single machine to exploit software vulnerabilities in other systems.

In WiFi networks, an SSID is used to uniquely identify a wireless access point.

Network complexity decreases the likelyhood of potential security issues.

End-to-end encryption secures data only on physical communication links.

In link encryption, decryption occurs as the communication leaves the sending computer.

Digital Distributed Authentication uses private keys to generate digital signatures, which can be verified using public keys.

Kerberos is designed to be deployed in environments that employ purely asymmetric cryptographic systems.

CORBA mandates the use of Kerberos for all authentication processes in distributed object interactions.
