Network and Security Foundations Study Guide
Use this study guide as an aid to assist you in understanding the 3 competencies that this course will cover. It is
important
that you read the whole course. You will need to understand all the topics listed in this study guide and
reading the course is going to provide that context to help with that.
Another great aid for understanding what is discussed in this course are the cohorts that we offer. I
would highly recommend signing up and attending the cohorts.
For exam know the following well:
OSI and TCP/IP models
Network commands: ipconfig; nmap; etc
Different networks: WAN, WLAN etc and what they do
Scenarios for CIA and AAA – practice test on course tips is helpful
Firewalls (packet filtering, stateful, proxy server, application
Switches, repeater, hubs, routers, modems
Know some about the different cables and uses
Topologies such as star, bus, mesh, ring
Type 1 and 2 hypervisor
SAAS , private/public
cloud Insider threats
The different types of attacks and mitigation for them – a lot on test on
this Watch the Professor messor videos for OSI and TCP/IP models

Unit 2: Introduction to Networking Concepts
OSI Model & TCP/IP Model
OSI (Open System Interconnection) Model
Use the mnemonic: A Penguin Said That Nobody Drinks Peps
Layer What happens at each layer?
Characteristic Components: HTTP, FTP, SMTP,
Layer 7 DNS This is the layer we see <Your Eyes=
Applicatio
n PDA - Functions: Support for applications
Data Ex: Work, Excel, Web browser
Characteristic Components: Application encryption (SSL/TLS)
Layer 6
Presentati Often combined with the Application Layer at layer 7
on PDA - Function: Data format translation, data compression, and
Data data encryption/decryption take place at this layer
Characteristic Components: Controls protocols, tunneling protocols
Links the presentation to the transport layer
Layer 5 Communication management between devices
Session ● Authentication and Authorization take place here
PDA - ● Responsible for establishing, maintaining, and terminating a
Data connection between two systems.
● Where you use <Controls protocols= or <Tunneling protocols= between
one
device or another
