What does Windows use for Anti-Virus?
Microsoft Defender Antivirus
Microsoft Defender Antivirus is a built-in anti-malware program in Windows. It was first made available as a free anti-spyware download for Windows XP, and later came pre-installed with Windows Vista and Windows 7. It has matured into a comprehensive antivirus program that is included with Windows 8 and later editions, replacing Microsoft Security Essentials.
Defender Antivirus was a graphical desktop software prior to Windows 10. Users may now administer Defender Antivirus directly through the Windows Security app or PowerShell, starting with Windows 10 and Windows Server 2016. Microsoft Defender Antivirus is part of the Microsoft Defender for Endpoints suite of products.

What does windows use to filter traffic in and out of the network?
Windows Firewall is a host-based firewall that applies security on a computer by blocking unauthorized access to its services and decreasing its exposure to potentially destructive network probes when connected to the Internet or a local intranet.
Windows Firewall is managed using two applications. Namely, Windows Firewall (known as Windows Defender Security Center in Windows 10) and Windows Defender Firewall with Advanced Security. Windows Defender Firewall with Advanced Security includes features for creating rules for granular control of Inbound and Outbound traffic. It has Connection Security Rules for creating IPsec policies and network isolation. It has been available in versions of Windows dating back to Windows Vista.
What does Windows Firewall support?
Internet Protocol security (IPsec) is supported by Windows Defender Firewall, allowing you to require authentication from any device attempting to communicate with your device. Devices that can’t be authenticated as trusted devices can’t communicate with your device when authentication is required. You can also use IPsec to encrypt particular network traffic to prevent it from being read by network packet analyzers that a malicious user could use to connect to the network.
What are the advantages of using Windows Firewall?
Defend against network security attacks. The Windows Defender Firewall minimizes the device’s attack surface, adding another layer to the defense-in-depth approach. Reducing a device’s attack surface improves manageability and reduces the chances of a successful attack.
Protects sensitive information and intellectual property.
Increases the value of current investments. There is no need for additional hardware or software because Windows Defender Firewall is a host-based firewall that comes with the operating system.
How can you Activate and Deactivate Windows Defender firewall?
Settings> Privacy & Security > Windows Security > Firewall & Network Protection>
What Profiles can you set on rules for in Windows Defender Firewall?
Domain - The domain profile is used in networks where the host system may connect to a domain controller and authenticate.
Private - It’s a user-assigned profile. The private profile is used to designate private or home networks.
Pubic/Guest - This is the default profile and is used to identify public networks like Wi-Fi hotspots at coffee shops, airports, and other places.
Why would you deactivate the firewall?
If you have another software firewall installed on your computer that you would like to use over the Windows Defender Firewall.
When you’re trying software installations, networking, and other things and can’t get them to work, deactivating the firewall can be used as a troubleshooting step because everything could be perfect except for a particular firewall rule.
You want to set up a honeypot. A honeypot is a controlled and safe environment for showing how attackers work and examining different types of threats. With a honeypot, security staff won’t be distracted by real traffic using the network - they’ll be able to focus 100% on the threat. Honeypots can also catch internal threats.
How to create a rule Blocking a Port via Windows Firewall?
wf.msc> Windows Defender Firewall> Windows Firewall with Advanced Security >
You can set rules through:
Inbound Rules - Used to configure rules for traffic coming into the system
Outbound Rules - Used to configure rules for traffic leaving the system
Connection Security Rules - Used to configure extra layers of authentication and security
Monitoring - Shows each profile along with pertinent information to logging and monitoring
You can go to the Action pane (On the right) right click > New Rule > You can follow the prompts from Wizard to select radio button

What does windows use for encryption?
BitLocker Drive Encryption is an encryption feature provided by Windows to protect your data, particularly when lost or stolen. Windows has a long history of providing solutions for at-rest data protection. BitLocker has recently added encryption for both full drives and portable drives. Windows consistently improves data security by improving existing options and introducing new ones.
BitLocker provides the most protection when combined with a Trusted Platform Module (TPM) version 1.2 or later. TPM is a hardware component included in many newer computers by computer manufacturers. It works with BitLocker to protect user data and ensure that a computer was not tampered with while the system was turned off.
What is BitLocker To Go?
BitLocker To Go is BitLocker Drive Encryption for portable storage devices. This feature encrypts the following data: USB flash drives, external hard disk drives, SD memory cards, and other drives that have been formatted with the NTFS, FAT16, FAT32, or exFAT file systems. As with BitLocker, you can open BitLocker To Go encrypted drives on another computer by using a password or smart card.
What is the EFS function do?
The Encrypted File System, or EFS, adds another layer of security to files and directories. It uses a public-key system to provide cryptographic protection for individual files on NTFS file system volumes.
Note that the following items cannot be encrypted:
System files
Transactions
System directories
Root directories
Files that are compressed
How to activate BitLocker To Go?
File Explorer > This PC> Right Click Drive > Devices and Drives Section > Select Turn on BitLocker
Here you will enable the Use a password to unlock the drive checkbox.
Note: Ensure you choose the correct encryption based on the recommended settings in a real-life situation.
