Asphyxium Posted November 4, 2012 Share Posted November 4, 2012 This exists in my other post but I feel it should be pointed out clearly. There is an undocumented feature in Windows Vista, 7, and 8 (now 8 is a bit different and I'm unsure this procedure will work as stated) that allows you to protect a system from DDOS attacks. According to speedguide.net: "SynAttackProtect This undocumented setting provides protection against SYN denial of service (DoS) attacks. When enabled, connections timeout sooner if SYN attack is detected. When set at 1, TCPMaxDataRetransmissions can be lowered further. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters" Create the following new DWORD (32-bit if running a 64-bit machine) entry in the parameters key: "SynAttackProtect=1 (DWORD, recommended:" <decimal>"1, not present in registry by default)" Hopefully no one will chew me out this time.

Super Fast Posted November 4, 2012 Share Posted November 4, 2012 Thanks for the alert. This will probably be more useful for business scenarios, as they are higher profile. While home users certainly have the possibility of such attacks, they are usually directed at businesses or organizations because of being more public. Sounds like it may be useful for business users.... Link to comment Share on other sites More sharing options...
Moderators Nergal Posted November 4, 2012 Moderators Share Posted November 4, 2012 I know my business hardware firewall was set to block syn attacks (the logs were full of them, but I think we were bashed against a lot) ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.

TheWebAtom Posted November 5, 2012 Share Posted November 5, 2012 It only protect against SYN flooding. DHT, HTTP and TCP flooding will still bring the system down just fine I'm Shane. Link to comment Share on other sites More sharing options...
