Windows Security

Per Microsoft, "Windows Security is your home to manage the tools that protect your device and your data".

In case you missed it, Windows Security is also available in Settings.

 

 

 

 

 In the above image, focus your attention on Protection areas.

• Virus & threat protection
• Firewall & network protection
• App & browser control
• Device security

Each following task will briefly touch on these areas.


Before proceeding, let's provide a quick comment on the status icons.

• Green means your device is sufficiently protected, and there aren't any recommended actions.
• Yellow means there is a safety recommendation for you to review.
• Red is a warning that something needs your immediate attention.

    

Click on Open Windows Security.

 

 

 

Note: Since the attached VM is a Windows Server 2019 edition, it looks different from a Windows 10 Home or Professional edition.

The below image is from a Windows 10 device.

 

 

 

1) In the above image, which area needs immediate attention?

Ans - Virus and Threat Protection


 

Virus & threat protection

Virus & threat protection is divided into two parts:

• Current threats
• Virus & threat protection settings

The image below only focuses on Current threats. 

 

 

 

Current threats

Scan options

• Quick scan - Checks folders in your system where threats are commonly found.
• Full scan - Checks all files and running programs on your hard disk. This scan could take longer than one hour.
• Custom scan - Choose which files and locations you want to check.

Threat history

• Last scan - Windows Defender Antivirus automatically scans your device for viruses and other threats to help keep it safe.
• Quarantined threats - Quarantined threats have been isolated and prevented from running on your device. They will be periodically removed.
• Allowed threats - Allowed threats are items identified as threats, which you allowed to run on your device.

Warning: Allow an item to run that has been identified as a threat only if you are 100% sure of what you are doing.


Next is Virus & threat protection settings.

 

Virus & threat protection settings

Manage settings

• Real-time protection - Locates and stops malware from installing or running on your device.
• Cloud-delivered protection - Provides increased and faster protection with access to the latest protection data in the cloud.
• Automatic sample submission - Send sample files to Microsoft to help protect you and others from potential threats.
• Controlled folder access - Protect files, folders, and memory areas on your device from unauthorized changes by unfriendly applications.
• Notifications - Windows Defender Antivirus will send notifications with critical information about the health and security of your device.

Warning: Excluded items could contain threats that make your device vulnerable. Only use this option if you are 100% sure of what you are doing.

Virus & threat protection updates

Check for updates - Manually check for updates to update Windows Defender Antivirus definitions.  

Ransomware protection

Controlled folder access - Ransomware protection requires this feature to be enabled, which in turn requires Real-time protection to be enabled.



Note: Real-time protection is turned off in the attached VM to decrease the chances of performance issues. Since the VM can't reach the Internet and there aren't any threats in the VM, this is safe to do. Real-time protection should definitely be enabled in your personal Windows devices unless you have a 3rd party product that provides the same protection. Ensure it's always up-to-date and enabled.  

Tip: You can perform on-demand scans on any file/folder by right-clicking the item and selecting 'Scan with Microsoft Defender'.


The below image was taken from another Windows device to show this feature.



1) Specifically, what is turned off that Windows is notifying you to turn on?

Ans - Real-time protection

Firewall & network protection

What is a firewall?

Per Microsoft, "Traffic flows into and out of devices via what we call ports. A firewall is what controls what is - and more importantly isn't - allowed to pass through those ports. You can think of it like a security guard standing at the door, checking the ID of everything that tries to enter or exit".

The below image will reflect what you will see when you navigate to Firewall & network protection.

Note: Each network may have different status icons for you.

What is the difference between the 3 (Domain, Private, and Public)?

Per Microsoft, "Windows Firewall offers three firewall profiles: domain, private and public".

• Domain - The domain profile applies to networks where the host system can authenticate to a domain controller.
• Private - The private profile is a user-assigned profile and is used to designate private or home networks.
• Public - The default profile is the public profile, used to designate public networks such as Wi-Fi hotspots at coffee shops, airports, and other locations.

If you click on any firewall profile, another screen will appear with two options: turn the firewall on/off and block all incoming connections.

Warning: Unless you are 100% confident in what you are doing, it is recommended that you leave your Windows Defender Firewall enabled.

Allow an app through firewall

You can view what the current settings for any firewall profile are. In the above image, several apps have access in the Private and/or Public firewall profile. Some of the apps will provide additional information if it's available via the Details  button. 

Advance Setting

 

Configuring the Windows Defender Firewall is for advanced Windows users. Refer to the following Microsoft documentation on best practices here.

Tip: Command to open the Windows Defender Firewall is WF.msc.


1) If you were connected to airport Wi-Fi, what most likely will be the active firewall profile?

Ans - public network

App & browser control

In this section, you can change the settings for the Microsoft Defender SmartScreen.

Per Microsoft, "Microsoft Defender SmartScreen protects against phishing or malware websites and applications, and the downloading of potentially malicious files".

Refer to the official Microsoft document for more information on Microsoft Defender SmartScreen here.

Check apps and file

Windows Defender SmartScreen helps protect your device by checking for unrecognized apps and files from the web.

Exploit protection

Exploit protection is built into Windows 10 (and, in our case, Windows Server 2019) to help protect your device against attacks.

Warning: Unless you are 100% confident in what you are doing, it is recommended that you leave the default settings.

Device security

Even though you'll probably never change any of these settings, for completion's sake, it will be covered briefly.

Core isolation
 

Memory Integrity - Prevents attacks from inserting malicious code into high-security processes.

Warning: Unless you are 100% confident in what you are doing, it is recommended that you leave the default settings.

The below images are from another machine to show another security feature that should be available in a personal Windows 10 device.

Security processor

Below are the Security processor details.

What is the Trusted Platform Module (TPM)?

Per Microsoft, "Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. The chip includes multiple physical security mechanisms to make it tamper-resistant, and malicious software is unable to tamper with the security functions of the TPM".
