Study Notes

Security and Network Concepts

Various types of attacks include Denial of Service (DoS), phishing, and Man-in-the-Middle, which pose significant risks to network integrity.
A service model that is NOT part of cloud computing is "Software as a Service (SaaS)" alongside others like Infrastructure as a Service (IaaS) and Platform as a Service (PaaS).
Network threats can be identified using threat detection tools such as Intrusion Detection Systems (IDS) or Security Information and Event Management (SIEM) solutions.
Characteristics of the cloud include scalability, flexibility, and resource pooling, which enhance operational efficiency.
A type of network segmentation highlighted is "VLAN (Virtual Local Area Network)," which helps isolate traffic for better performance and security.

Network Security and Management

An example of a network threat NOT mentioned is "Physical hardware theft," which is less focused compared to malware or unauthorized access.
The primary purpose of a Virtual Private Network (VPN) is to create a secure tunnel for data transmission over unsecured networks, ensuring user privacy.
A network attack characterized by overwhelming a system is a "Distributed Denial of Service (DDoS)" attack, which disrupts normal operations.
A network security tool designed for detecting and preventing unauthorized access is a "Intrusion Prevention System (IPS)."

Networking Protocols and Functions

The primary purpose of the Network Layer in the OSI model is packet forwarding and routing through logical addressing.
SFTP (Secure File Transfer Protocol) is the network protocol used for securely transferring files between a client and server.
A network switch primarily functions to connect devices on a local area network (LAN) and manage data traffic effectively.

Cloud and Deployment Models

A hybrid cloud deployment model combines both public and private cloud infrastructures for better resource utilization and flexibility.
The primary role of a network firewall is to monitor and control incoming and outgoing network traffic based on predetermined security rules.
DNS (Domain Name System) protocol translates human-readable domain names into IP addresses, enabling easier access to websites.

Network Access and Learning Objectives

The primary purpose of a Network Access Control (NAC) system is to enforce policies on devices attempting to connect to a network to protect resources.
A key learning objective of Chapter 4 encompasses understanding network security threats and countermeasures.
Learning objectives NOT covered in Chapter 4 might include advanced programming concepts not related to networking fundamentals.
Focus areas in Module 1 include grasping the basics of computer networking and foundational concepts.
Module 2 covers understanding common protocols and ports critical for network communication.
Key aspects of Module 3 highlight the importance of securing network infrastructure against potential vulnerabilities.
A learning objective related to types of network threats and attacks emphasizes recognizing various security risks and implementing defensive strategies.
