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
