Windows Defender Firewall is an integral part of Windows client’s security framework. The firewall helps to shield the operating system from malicious attacks coming from the internet or a network.
Planning and Implementing the Windows Defender Firewall
Implementing the Windows Defender Firewall involves creating a detailed plan that factors in your network architecture and the firewall needs of the individual applications. You can configure it by navigating to Control Panel > System and Security > Windows Defender Firewall > Advanced settings. Here you can specify inbound and outbound rules, connect security exceptions, and configure advanced settings according to your security plan.
BitLocker
BitLocker is a security feature that provides data protection for your system. It helps prevent unauthorized access to system files by encrypting the entire Windows operating system volume.
Planning and Implementing BitLocker
You would need to consider the prerequisites, and recovery options before implementing BitLocker. Devices should have a compatible TPM chip, as well as a BIOS or UEFI firmware that can read from a USB device during startup. Batch scripts or PowerShell cmdlets can be used for the BitLocker implementation. For example, the Enable-BitLocker
cmdlet can be used to turn on BitLocker for a particular volume.
Enable-BitLocker -MountPoint "C:" -EncryptionMethod XtsAes128 -TpmProtector
Windows Hello
Windows Hello is a biometric authentication feature in Windows 10, designed to provide safer and more user-friendly access than traditional passwords.
Planning and implementing Windows Hello
To use the Windows Hello feature, a device will need either a fingerprint reader, illuminated IR sensor, or other biometric sensors. Windows Hello can be activated through Settings > Accounts > Sign-in options. Biometric data can be captured here to enable secure sign-in.
Windows Information Protection (WIP)
WIP is a data leak prevention feature that helps users separate their work and personal data on their Windows 10 devices.
Planning and Implementing WIP
Enterprises planning to use WIP should first inventory their apps and decide which apps should have access to work data, then they should create a WIP policy using Microsoft Intune or another MDM solution and finally apply the policy to user or device groups. Applying policies can be done through PowerShell or through the Azure portal.
Overall, enhancing the security of Windows clients in a Microsoft 365 environment requires intentional planning and detailed implementation. By understanding Windows Defender Firewall, BitLocker, Windows Hello, and Windows Information Protection, you’re well-equipped to tighten the security of your Windows clients. Always remember to consult official Microsoft documentation to stay updated with the ever-evolving security features.
