Distributed Denial of Service (DDoS) Protection with Registry Hacks

Hello...!!!, Here is a simple trick for protecting Distributed Denial of Service (DDoS) Attack using Windows Registry Hacks.

Open up regedit

(Start--->RUN--->Regedit)

• Go-to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Win dows
• Under Windows, add a new key called Psched, it may already be there.
• Under the key Psched, add a DWORD value named "MaxOutstandingSends" without quotes, of course.
• Once you have created the DWORD value named MaxOutstandingSends, right click on it and click modify.
• Under value data, put 65535. Under base, Hexadecimal should be chosen.

Here's a few other registry values/keys to stop DoS/DDoS attacks in the event that you have a weak connection and your system can't even withstand 65535 connections:

[HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP\PARAMEERS]

"SYNAACKPROTECT"=DWORD:00000002

"TCPMAATARETRANSMISSIONS"=DWORD

"TCPMAXHALFOPEN"=DWORD:64

"TCPMAXHALFOPENRETRIED"=DWORD:50

"TCPMAXPORTSEXHAUSTED"=DWORD:1

"TCPMAXCONNECTRESPONERETRANSMISSIONS"=DWORD:2

"ENABLEDEADGWDETECT"=DWORD:0

"ENABLEPMTUDISCOVERY"=DWORD:0

"KEEPALIVETIME"=DWORD00000

"ALLOWUNQUALIFIEDQUERY"=DWORD:0

"DISABLEDYNAMICUPDATE"=DWORD:1
