課程 5（共 5 門，Specialization Google IT Support Professional Certificate）

This course covers a wide variety of IT security concepts, tools, and best practices. It introduces threats and attacks and the many ways they can show up. We’ll give you some background of encryption algorithms and how they’re used to safeguard data. Then, we’ll dive into the three As of information security: authentication, authorization, and accounting. We’ll also cover network security solutions, ranging from firewalls to Wifi encryption options. Finally, we’ll go through a case study, where we examine the security model of Chrome OS. The course is rounded out by putting all these elements together into a multi-layered, in-depth security architecture, followed by recommendations on how to integrate a culture of security into your organization or team. At the end of this course, you’ll understand: ● how various encryption algorithms and techniques work as well as their benefits and limitations. ● various authentication systems and types. ● the difference between authentication and authorization. ● how to evaluate potential risks and recommend ways to reduce risk. ● best practices for securing a network. ● how to help others to grasp security concepts and protect themselves.

In the second week of this course, we'll learn about cryptology. We'll explore different types of encryption practices and how they work. We'll show you the most common algorithms used in cryptography and how they've evolved over time. By the end of this module, you'll understand how symmetric encryption, asymmetric encryption, and hashing work; you'll also know how to choose the most appropriate cryptographic method for a scenario you may see in the workplace.

Instructions for Accessing Linux Qwiklabs5:08

In this video, we're going to learn how to access

the Linux Virtual Machines from the Coursera Platform.

As you can see here, there's some information but what we'll be doing in the lab.

It's learning objectives, and how much time you had

to complete it before you could access the lab itself.

First, you'll need to click the checkbox and provide

an electronic signature adhering to Coursera's Honor Code.

Then, you will click the "open tool" button.

After you click the button,

you'll be navigated to a new browser tab.

What you see here, is the Qwiklabs environment.

Each Qwiklab comes with details,

step by step instructions about what you need to do to complete the lab.

To start the lab, go to the top right hand of

the screen and click the green button that says, "start lab."

After you click the button,

it will take some time to load and set up the lab and the environment.

While it's loading, this is a good time

to read through the instructions about what you'll need to do.

After the loading bar has filled up completely,

you're now ready to access the Google Cloud Console.

Google's Cloud Console technology powers the Qwiklab environments.

So, in order to access your Linux Virtual Machine,

first, we need to sign into the Google Console.

To do this, click the orange button on

the left-hand side of the screen that says, "open Google Console".

This will open a new web browser tab that you'll need to sign into.

You will not use your own personal Gmail account to access the Google Console.

If you're using a Gmail account right now,

make sure to sign out of it before moving on to the next step.

Let's go back to the previous tab.

You're going to use the username and password that you see under

the orange "open Google Console" button to authenticate.

To do this, copy the username by clicking the "copy" button on the right-hand side,

then paste into Gmail in the other tab.

Then, we're going to do this for the password too.

Copy the password and paste it into Gmail.

After you pasted the password, click "next."

Next, you'll see a Terms of Service agreement from Gmail.

To continue on, click "accept."

After you click "accept" Gmail will ask you to

provide a recovery phone number and email address.

You don't need to add a recovery phone number or email,

because each time you access Qwiklabs,

you'll use a new Gmail username and password to sign in.

So, for now, just click "done."

Next, you'll see the Google Cloud Platform interface.

A pop-up with the Terms of Service agreement will appear.

And you don't need to sign up for updates because this isn't your email address.

Make sure you do click "yes" to agree to the Terms of Service.

Then click "accept."

Now, you have access to the Google Cloud Platform.

What we want to do now is access Linux Virtual Machine.

To do this, navigate to the menu on the left-hand side of the screen,

go to "Compute Engine" and then click on "VM instances."

You'll now see a Virtual Machine instance of the Linux operating system,

called Linux Dash instance.

There are a couple of ways you can access the Linux Virtual Machine.

You can click on the "project name",

click on the dropdown arrow under "Connect", or click "SSH."

I'm going to click "SSH," this will pop up a new screen.

Let the screen load for a bit, and after a while,

you'll see the Linux operating system appear in the pop-up screen.

How cool is that?

This is a working instance of Linux OS.

Now, you're ready to complete the tasks in the lab.

You can input Linux commands and continue on with the exercises.

When you're done completing the lab exercises,

simply close the window with the Linux operating system.

You should also close the tab with the Google Cloud Platform.

Next, go back to the tab in your browser with Qwiklabs.

When you're done, click the red "end lab"

button in the top-right hand corner of the screen.

You'll see a warning asking you if you want to end this lab.

After you choose to end the lab,

you won't be able to access your previous work,

so only end the lab when you're sure you're done.

You can also provide a star rating or a comment about the lab itself.

This will help the Google team improve labs for the future. And that does it.

Go back to the Coursera Platform,

and continue with your learning experience.

This graded assessment will now be marked as complete.
