FireWallDiskManipulationEventArgs Class

Event arguments raised by the firewall when disk manipulations has been discovered

Object Model

Syntax

public class FireWallDiskManipulationEventArgs : Walter.IO.EventArguments.DiskManipulationEventArgs

Remarks

This argument allows you to perform a choice of actions the firewall will do for all future requests

Example

The following code shows how to use the firewall to send an mail (if mail add-on installed) when a change on disk is detected by a application that is actually communicating via the network. This could be RemoteDesktop WinVCM or TeamViewer, Telnet, FTP etc.

private void MyFireWall_OnDiskManipulation(object sender, DiskManipulationEventArgs e)
 {
     foreach (var item in e.Violation.Talking)
     {
         if (item.tcpRecord.Scope == Walter.Net.Networking.CommunicationScopes.WAN)
         {
             (this as IFireWall).SendEmail(EMailRoles.SecurityRelevant
                                         , "A file change with external communication was detected"
                                         , MakeEmailBody(item.tcpRecord.Scope,e.Violation.ExecutingBinary, item.tcpRecord.RemoteAddress)
                                         , true);
         }
         else
         { 
             (this as IFireWall).SendEmail(EMailRoles.SecurityRelevant
                                         , "A file change with internal communication was detected"
                                         , MakeEmailBody(item.tcpRecord.Scope,e.Violation.ExecutingBinary, item.tcpRecord.RemoteAddress)
                                         , true);
            
         }
     }
     e.Action = ApplicationCompromisedActions.ShutDown | ApplicationCompromisedActions.PersistOnReboot;
 }
