Welcome to week 2, Network potocols
Congratulations on the progress you've made so far!
In this section, you'll learn about how
networks operate using tools and protocols.
These are the concepts that you'll use every
day in your work as a security analyst.
The tools and protocols you'll learn in this section of
the program will help you protect
your organization's network from attacks.
Did you know that malicious actors can take advantage of
data moving from one device to another on a network?
Thankfully, there are tools and
protocols to ensure the network
stays protected against this type of threat.
As an example, I once identified an attack
based solely on the fact they were
using the wrong protocol.
The network traffic volumes were right, and it
was coming from a trusted IP,
but it was on the wrong protocol,
which tipped us off enough to shut down
the attack before they caused real damage.
First, we'll discuss some common network protocols.
Then we'll discuss virtual private networks, or VPNs.
And finally, we'll learn about
firewall security zones and proxy servers.
Now that you have an idea of where we're
headed, let's get started.
