You are hardening a Windows Server 2022 management node. WinRM (HTTP/HTTPS) must accept connections only from two management subnets (10.10.20.0/24 and 10.10.30.0/24) and only when the traffic is authenticated with IPsec using Kerberos. No WinRM access is allowed on the Public profile. Which two configurations should you create in Windows Defender Firewall with Advanced Security?

Correct answer: A connection security rule (Server-to-Subnet) that requires inbound and outbound authentication using Kerberos for 10.10.20.0/24 and 10.10.30.0/24., Inbound firewall rules for TCP 5985 and 5986 limited to the Domain and Private profiles and scoped to remote addresses 10.10.20.0/24 and 10.10.30.0/24..
Why this is the answer
The correct options address the requirements for restricted WinRM access with Kerberos authentication. A connection security rule (Server-to-Subnet) requiring inbound and outbound Kerberos authentication for the specified subnets ensures that traffic between the management node and those subnets is secured and authenticated as required. Inbound firewall rules for WinRM ports (5985 for HTTP, 5986 for HTTPS) limited to the Domain and Private profiles and scoped to the management subnets ensure that WinRM is only accessible from the allowed subnets and not on the Public profile, fulfilling the "no WinRM access allowed on the Public profile" requirement. Incorrect options: An authentication exemption rule would bypass IPsec, which contradicts the requirement for IPsec authentication. An outbound firewall rule allowing TCP 5985/5986 to Any remote address on all profiles is overly permissive and violates the security requirements. A connection security rule of type Tunnel requiring certificates for authentication is not specified; the requirement is for Kerberos authentication, and a tunnel mode is not necessary for this scenario.
