The strategy described is known as a “default deny” firewall policy. This approach means that the firewall is configured to deny all traffic by default, except for the network services that are explicitly allowed. It is a restrictive security stance where only specified services are permitted, and everything else is blocked. This is considered a best practice in firewall configuration because it minimizes the attack surface by ensuring that only necessary services are accessible, thereby reducing the potential vectors for attack.

References: The concept of a default deny policy is a fundamental principle in network security and is advocated by various cybersecurity authorities, including the EC-Council’s Certified Network Defender (CND) program. It is also detailed in cybersecurity literature and aligns with best practices from organizations such as the National Institute of Standards and Technology (NIST)123.

To check if SMB1 is enabled or disabled, the correct PowerShell command is Get-WindowsOptionalFeature -Online -FeatureName SMB1Protocol. This command queries the status of the SMB1Protocol feature in the running instance of Windows. If SMB1 is enabled, the command will return its status as ‘Enabled’, and if it is disabled, it will return ‘Disabled’.

References: The correct syntax for the command is documented in various official Windows resources, including Microsoft’s own documentation on managing SMB protocols1. It is also aligned with the objectives of the EC-Council’s Certified Network Defender (CND) program, which includes knowledge of managing Windows network protocols and features.

Switch-based network monitoring requires additional monitoring software or hardware because switches operate at the data link layer of the OSI model and do not inherently provide monitoring capabilities. To monitor traffic through a switch, network administrators must use port mirroring or a network tap, which involves configuring the switch to send a copy of the network packets to a monitoring device. This allows the monitoring device to analyze the traffic passing through the switch without interfering with the network’s normal operation. This technique is essential for deep packet inspection, intrusion detection systems, and for gaining visibility into the traffic between devices in a switched network.

References: The need for extra monitoring software or hardware in switch-based network monitoring is consistent with the Certified Network Defender (CND) curriculum, which emphasizes the importance of implementing robust network monitoring practices to detect and respond to security threats12. Additionally, the use of port mirroring and network taps as methods to monitor switch-based networks is a standard practice in network security, aligning with the CND’s focus on technical network security measures34.
