Hello

 

I'm trying to create an ESA Rule for a windows system, where an account is created, and then the user is logged in.

 

Basically when an account is created the user_dst is Administrator but the user_src is the account name in this case mynewuser4

 

When the user logs in this is in the user_dst of the event.

 

I think there is a mistake in the part highlighted below, but I cant work out what it is.

 

 

My rule is:

/*

  This basic template is a placeholder for defining basic EPL content that can be

  installed and executed in ESA. The sample below is the minimum that would be

  required to get started.

 

  Version:  3.0

*/

/*

Module debug section. If this is empty then debugging is off.

*/

/* EPL section. If there is no text here it means there were no statements. */

    module Module_575ec959e4b003f2f0b9a8da;

 

        @Name('Module_575ec959e4b003f2f0b9a8da_Alert')

        @Description('User Account Created and then logged in')

        @RSAAlert(oneInSeconds=0)

 

@Name('Result')     SELECT * FROM Event(

            /* Statement: User Account Created */

            (event_desc .toLowerCase() LIKE '%account was created%' and user_src is not null)

            OR

            /* Statement: User Logged In */

            (event_desc .toLowerCase() LIKE '%successfully logged on%' and user_dst is not null)

           

            ).win:time(10 Minutes)

        MATCH_RECOGNIZE (

                        MEASURES E1 as e1_data , E2 as e2_data

  PATTERN (E1 E2)

        DEFINE

        E1 as (E1.event_desc .toLowerCase() LIKE '%account was created%'),

        E2 as ( (E2.event_desc .toLowerCase() LIKE '%successfully logged on%') and E2.user_dst=E1.user_src)

        );

 

However, I cant seem to get it to fire.

 

Here are some logs to trigger the alert:

It is generated on the computer that was accessed. The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network). The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on. The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The authentication information fields provide detailed information about this specific logon request. - Logon GUID is a unique identifier that can be used to correlate this event with a KDC event. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols. - Key length indicates the length of the generated session key. This will be 0 if no session key was requested.

 

The above worked on the ESPER Tryout page but not on my Security Analytics ESA Box
