Network Security Quiz

Study Notes

Network Transmission Media

Technologies such as cellular, Bluetooth, and near field communication (NFC) are categorized under wireless transmission media.

Types of Threats to Network Communications

Common threats include malware, phishing attacks, man-in-the-middle attacks, data breaches, and denial of service attacks.

DDoS in Network Security

DDoS stands for Distributed Denial of Service, a malicious attempt to disrupt the normal functioning of a targeted server, service, or network by overwhelming it with traffic.

Network Encryption Concepts

Network encryption concepts and tools are typically covered in specialized chapters of cybersecurity textbooks, focusing on protocols, algorithms, and security frameworks.

OSI Model

The OSI Model (Open Systems Interconnection Model) is a conceptual framework used to understand and implement network communications through seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.

Examples of Network Transmission Media

Examples include wired media like Ethernet cables and fiber optic cables, alongside wireless variants such as Wi-Fi and satellite communications.

Purpose of a Firewall

The main purpose of a firewall is to monitor and control incoming and outgoing network traffic based on predetermined security rules, acting as a barrier between trusted and untrusted networks.

Data Corruption Threats

Data corruption is typically classified as a type of integrity threat, where unauthorized individuals may alter data in transit, leading to misinformation and loss of trust.

Intrusion Detection and Prevention Systems

Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) are technologies that monitor network or system activities for malicious actions or policy violations.
