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.
