Server Guard

Features | Detailed Description

The Server Guard is a component from the Clever Internet Suite library.
This component provides algorithms for protecting server connections from brute force attacks, connection flood attacks, user and IP filtering functionality and many more.

Use this class together with any server component from Clever Internet Suite to protect your server from hackers, viruses, and other malicious activity.

Available in .NET, VCL and ActiveX editions.

Features:

  • Block brute force attacks
  • Limit connections per IP / time interval
  • Black IP list and White IP list
  • Accept IP Class C whildcards
  • Login delay: Incremental, Random, Custom
  • Lock users
  • Customizing the attack detection process

How to use with Clever Internet Suite servers

Please use the steps below to add server protection functionality to your server application:

  • Put the ServerGuard component on to a form.
  • Assign the FtpServer.Guard (or Pop3Server or SmtpServer) property with instance of the ServerGuard component.
  • Customize ServerGuard settings, if required.

Using with third-party server components

The ServerGuard component provides independent interface and allows you to protect any third-party server component. All what you need is to call to the ServerGuard.Connect method when accepting the next connection from remote peer. If this method returns False then close the connection and reject the user. For protecting your server from brute force attacks, please use another method - ServerGuard.Login.

Delphi 
if (not Guard.Connect(connection.PeerIP, Port)) then
begin
   raise Exception.Create('Connection blocked');
end;

C# 
isAuthorized = Authenticate(...);
if (!Guard.Login(connection.UserName, isAuthorized, connection.PeerIP, this.Port)) {
   throw new Exception("User blocked");
}
