Anti DDoS Guardian - Protect your Windows servers from DDoS attacks.

Anti DDoS Guardian stops Distributed Denial of Service (DDoS) attacks for Windows Servers, such as Apache servers, IIS servers, online game servers, mail servers, FTP servers, VOIP PBX and SIP servers and other Internet servers. The DDoS protection manages TCP flow and network flow and keeps attack traffic out. Anti DDoS Guardian protects Windows servers from most DDoS/DoS attacks, including brute force password guessing attacks, SYN flood, IP flood, TCP flood, UDP flood, ICMP flood, bandwidth attacks, etc. This DDoS protection firewall limits network flow number, client bandwidth, TCP connection number of each client, UDP/ICMP packet rate, and most importantly, it controls TCP half-open connection which is effective to block SYN flood. Anti DDoS Guardian can be successfully deployed on Windows website server machines, in a production environment, to easily ban country IP addresses with Apache's .htaccess files. In addition, this Anti DDoS software can be used as a simple firewall and the firewall rules are based on IP address, port, protocol, and other TCP/IP factors. It supports IP black list and white list, IP list automatically updating, exceptional rules, log files, network activity displaying in real-time, IP address looking up and other powerful features. In order to get high performance, this Anti DDoS protection firewall can be configured to start when the Windows is booted and run in the background as a Windows service. Anti DDoS Guardian is fully compatible with Windows 2000, XP, 2003, 2008, Vista, Windows 7, Windows 8, in 32-bit and 64-bit. Version 2.3 adds protection against slow HTTP DDoS attacks.

How to stop DDoS?

Anti DDoS Guardian stops DDoS attacks by several settings, such as the maximum number of TCP connections, bandwidth of each client computer, the maximum number of incoming UDP/ICMP packets per second,  and the maximum number of incoming TCP concurrent half-open connections, etc. These functions can be successfully used to block many DDoS attacks.

How to block brute-force password guesssing attacks?

It is observed that most brute force attacks subvert Internet servers by excessive password attempts. Anti DDoS Guardian was designed to limit the number of TCP incoming connections within a certain period of time. In this way, most brute force attacks are blocked.

How to block country IP addresses?

In some cases, we need to block country IP addresses, especially for website masters who want to protect Windows servers, such as HTTP servers, mail servers, FTP servers, VOIP PBX and SIP servers. Anti DDoS Guardian can be successfully used by website administrators on Windows servers machines ( Windows 2000, 2003, 2008, Windows 7, Vista, both in 32 bits and 64 bits ) , in a production environment, to easily ban traffic from whole countries. Users can simply download Apache's .htaccess files which can be easily downloaded from a lot of websites and then import the .htaccess files.

How does Anti DDoS Guardian work?

First of all, Anti DDoS Guardian works under NDIS (Network Driver Interface Specification) layer, which is the first layer that incoming network traffic passes through. Since NDIS filtering occurs at such a low level, Anti DDoS Guardian can filter each incoming and outgoing network packet. When a packet is received or sent from the user's computer, this DDoS protection will check it and determine to drop or allow it based on Anti DDoS policy.

Second, Anti DDoS Guardian manages network traffic in the form of TCP connections and network flows. It limits the number of TCP connections of each client, the bandwidth of each client, and the number of network flows that an Internet server can hold. This Anti DDoS firewall restricts UDP and ICMP packet rate, and most importantly, it controls TCP half-open connection which is effective to combat SYN flood.

Third, this Anti DDoS software utilizes IP list file to protect Internet servers. Particularly, country IP addresses in the form of Apache's .htaccess file or other P2P IP filter file can be imported to ban country IP addresses. IP list file can be updated periodically by configuring IP list management. In addition, both IP black list and white list are supported.

Last, firewall rules based on TCP/IP protocols can be used in Anti DDoS Guardian. Users can specify a rule by IP address, port, protocol, and other TCP/IP factors. This is the third layer to protect Internet servers from being attacked. 

Who use Anti DDoS Guardian?

• Website masters who want to protect HTTP servers, proxy servers, online game servers, Email serves, FTP servers, Internet forum servers and VoIP PBX SIP servers.

• IT administrators who need to set special TCP/IP protocols based firewall rules. 

• Protecting Windows servers from Distributed Denial of Service (DDoS) attacks,including brute force password guessing attack, SYN flood, TCP flood, UDP flood, ICMP flood, bandwidth attack and so on. 

• Network flow and TCP flow management. Anti DDoS Guardian limits network flow number, client bandwidth, TCP connection number of each client, UDP/ICMP packet rate. 

• TCP half-open connection control.

• Blocking country IP addresses.

• Blocking certain IP addresses or ranges of addresses.

• Firewall protection. The firewall rules are based on remote IP addresses, ports, protocols, and other TCP/IP factors.

• IP black list and white list. Anti DDoS Guardian controls users' access to the Internet within particular areas by setting black list or white list.

• Supporting many IP list formats, such as Apache's .htaccess, PeerGuardian IPfilter file, Emule IPfilter file and other P2P filter files.

• IP list automatic updating.

• Exceptional rules.

• Real-Time network activities monitoring. Anti DDoS Guardian monitors each incoming and outgoing packet in Real-Time. It displays local address, remote address, and other information of each network session.

• Looking up IP addresses. Anti DDoS Guardian looks up the remote IP addresses and ownership information.

• Log files. Anti DDoS Guardian records each blocked and allowed IP address.

• Running Anti DDoS Guardian as a Windows service.

• Supporting 64-bit Windows Operating System, such as 64-bit Windows 2008, 64-bit Windows Vista, and 64-bit Windows 7.

• Microsoft Windows 2000, XP, 2003, 2008, Vista, Windows 7 (32-bit and 64-bit)
