How to prevent Windows blue screen attack through firewall

  
                

When the Windows family's operating system crashes, it usually displays a blue screen with some complicated symbols and numbers. The blue screen attack is actually exploiting the kernel defect of the Windows operating system, or sending a large number of illegal format data packets to the attacked machine, causing the network layer of the Windows operating system to be damaged, causing a blue screen of death.
At present, the most common attack methods are:
l.NetBIOS attack: Send a data format illegal packet to port 139 of the machine using Windows 9x operating system. The typical attack tool is WINNUK.
2 .IGMP Attack: Sends IGMP packets of a large length and number to machines using the Windows 9x operating system. A typical attack tool is DOOM. 3. ICMP Attack: Sends a number to a machine using the Windows 9x operating system. Large and random types of ICMP packets.
For the above attacks, we can turn off NetBIOS, IGMP, and ICMP in the security level setting of the firewall. Closing these protocols will not affect the use of the Internet.
