Hello

I am fairly a beginner in coding and I have hit a snag.
I am developing a application that will monitor the security event log from startup and if there is a Logon Audit Failure event...my application will basically send a mail saying "Unauthorized access detected!"

my code snippet is :

C#

EventLog log = new EventLog("Security");
log.EnableRaisingEvents = true;

foreach (EventLogEntry entry in log.Entries)
{
    Console.WriteLine(entry.Message);
}
Console.ReadLine();

but every time i run this code there is Run time exception which says :

A first chance exception of type 'System.Security.SecurityException' occurred in mscorlib.dll

Additional information: Requested registry access is not allowed.

Can anybody point me towards a working solution?
please be as detailed as possible in your answer because I basically dont know anything and I want to know the internal workings of the code!

Thanks and Regards,
Kev

Your code looks correct. You should have Admin right to that system so that you can access all log from Windows EventLog.

This is the Quick Answers forum. If you want full details of the event logs and how to process them, then you need to use Google to search for samples and tutorials.

Right-click on your application and select "Run as Administrator".

Take a look at this (similar) question and the answer:

To access the Windows Security Log you need to have administrative privileges. Therefore, your app.manifest should be like this:

XML

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <assemblyIdentity version="1.0.0.0" name="MyApplication.app" />
   <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
      <security>
         <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
            <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
         </requestedPrivileges>
      </security>
   </trustInfo>
</asmv1:assembly>
