you will use the command line interface $($CLI$)$ to accomplish the steps in the following document with a screenshot.

Follow the instructions below. You will create a document containing $600+$ words and include

screenshots.

$1.$ Provide an introduction to Windows Firewall and PowerShell. In your introduction, explain what

a firewall is and why it's essential for network security. Also, discuss the benefits of managing

the firewall using PowerShell versus the graphical user interface $($GUI$).$

$2.$ Basic Commands:

$$ To add a rule to block an IP address:

New$-$NetFirewallRule $-$DisplayName "Block IP$"-$Direction Inbound $-$

Action Block $-$RemoteAddress $192\mathrm{.}168\mathrm{.}1\mathrm{.}100$

Writing: Describe what each part of the command does.

$$ To add a rule to block a port:

New$-$NetFirewallRule $-$DisplayName "Block Port" $-$Direction Inbound

$-$Action Block $-$Protocol TCP $-$LocalPort $8080$

Writing: Explain the significance of blocking specific ports.

$$ To block all incoming traffic:

Page $2$ of $3$

New$-$NetFirewallRule $-$DisplayName "Block All Incoming" $-$Direction

Inbound $-$Action Block

Writing: Highlight when and why you might use this command.

$$ To delete a rule:

Remove$-$NetFirewallRule $-$DisplayName "Block IP$"$

Writing: Discuss the importance of managing firewall rules and removing obsolete ones.

In addition, write a reflection on the importance of firewall management and how these

commands help secure a network.

$3.$ Tasks to complete $($screenshots are needed for each task$)$:

$$ Task $1$: Add a rule to block all incoming traffic from an IP address of your choice. To find out

the IP address of a website, in PowerShell, type the following:

nslookup websitename.com

$$ Task $2$: Add a rule to block all incoming TCP traffic on port $8080.$

$$ Task $3$: Add a rule to block all outgoing traffic.

$$ Task $4$: Open the browser and try going to that website. The website should be inaccessible.

$$ Task $5$: Delete the rule that blocks the IP address you blocked in task $1.$ Complete this task

last after completing part $4$ below.

$4.$ To verify that the firewall rules have been applied correctly in PowerShell, do the following

$($screenshots are needed for each task below$)$:

$$ List Existing Rules: Use this command to display a list of all firewall rules:

Get$-$NetFirewallRule

$$ Check Specific Rules: Filter the list to check specific rules by name:

Get$-$NetFirewallRule $-$DisplayName "Block IP$"$

$$ Check Active Firewall Rules: Ensure your new rules are active and applied:

Get$-$NetFirewallRule $|$ Where$-$Object $\{$ $$\_.$Enabled $-$eq 'True' $\}$

$$ Check Traffic: You can use Windows Defender Firewall with Advanced Security to

monitor and manage network traffic $($or you can use a tool called Wireshark.$)$ Here$$s how

you can do it using Windows Defender:

$-$ Open Windows Defender Firewall with Advanced Security:

$-$ Press Win $+$ R$,$ type wf$.$msc$,$ and press Enter.

$$ View Active Firewall Rules: In the left pane, click "Inbound Rules" or "Outbound Rules"

to see the current rules. Look for the rules you added, such as "Block IP$"$ or "Block Port."

$$ Check Rule Status: Double$-$click on a rule to open its properties. Ensure the rule is

enabled and correctly configured
