How to prevent Windows blue screen attacks through firewalls

When the Windows family's operating system crashes, it usually displays a blue screen with complex symbols and numbers. The blue screen attack actually takes advantage of the kernel flaw of the Windows operating system, or uses a large number of illegal format packets to send to the attacked machine, causing the network layer of the Windows operating system to be damaged, which causes the Bluetooth to panic.

Currently the most common types of attacks are:

L.netbios attack: Send a data format illegal packet to the 139 port of the machine using the Windows 9x operating system, and the typical attack tool has winnuk.

2.IGMP attack: Send a large length and number of IGMP packets to a machine using the Windows 9x operating system, typically with a doom attack tool.

3.ICMP attack: Send an ICMP packet with a large number of randomly varying types to the machine using the Windows 9x operating system.

For the above attacks, we can shut down NetBIOS, IGMP, and ICMP in the security level settings of the firewall, and shutting down these protocols will not affect the use of the Internet.
