Security Log Test

How often should the test be executed

The IP address of the host for which this test is to be configured.

Refers to the port used by the EventLog Service.  Here it is null.

Refers to the type of event logs to be monitored. The default value is security.

By default, this parameter displays none, indicating that by default none of the successful log audits will be reflected in the detailed diagnosis. If you set this parameter to, say 10, then the test will display only the 10 most recent successful log audits in the detailed diagnosis page. Setting this parameter to all, on the other hand will make sure that all successful log audits are listed in the detailed diagnosis.

By default, this parameter displays all, indicating that by default all the failed log audits will be reflected in the detailed diagnosis. If you set this parameter to, say 10, then the test will display only the 10 most recent log audits that failed, in the detailed diagnosis page. Setting this parameter to none, on the other hand will make sure that none of the failed log audits are listed in the detailed diagnosis.

The eG agent can either use WMI to extract event log statistics or directly parse the event logs using event log APIs. If the UseWMI flag is Yes, then WMI is used. If not, the event log APIs are used. This option is provided because on some Windows NT/2000 systems (especially ones with service pack 3 or lower), the use of WMI access to event logs can cause the CPU usage of the WinMgmt process to shoot up. On such systems, set the UseWMI parameter value to No. On the other hand, when monitoring systems that are operating on any other flavor of Windows (say, Windows 2003/XP/2008/7/Vista/12), the UseWMI flag should always be set to ‘Yes’.

Using this page, administrators can configure the event sources, event IDs, and event descriptions to be monitored by this test. In order to enable administrators to easily and accurately provide this specification, this page provides the following options:

• Manually specify the event sources, IDs, and users in the Filter text area, or,
• Select a specification from the predefined filter policies listed in the Filter box

For explicit, manual specification of the filter conditions, select the No option against the Policy Based Filter field. To choose from the list of pre-configured filter policies, or to create a new filter policy and then associate the same with the test, select the Yes option against the Policy Based Filter field. This is the default selection.

If the Policy based Filter flag is set to No, then a Filter text area will appear, wherein you will have to specify the event sources, event IDs, and event users to be monitored. This specification should be of the following format: {Displayname}:{event_sources_to_be_included}:{event_sources_to_be_excluded}:{event_IDs_to_be_included}:{event_IDs_to_be_excluded}:{users_to_be_included}:{ users_to_be_excluded}. For example, assume that the Filter text area takes the value, OS_events:all:Browse,Print:all:none:all:none. Here:

• OS_events is the display name that will appear as a descriptor of the test in the monitor UI;
• all indicates that all the event sources need to be considered while monitoring. To monitor specific event sources, provide the source names as a comma-separated list. To ensure that none of the event sources are monitored, specify none.
• Next, to ensure that specific event sources are excluded from monitoring, provide a comma-separated list of source names. Accordingly, in our example, Browse and Print have been excluded from monitoring. Alternatively, you can use all to indicate that all the event sources have to be excluded from monitoring, or none to denote that none of the event sources need be excluded.
• In the same manner, you can provide a comma-separated list of event IDs that require monitoring. The all in our example represents that all the event IDs need to be considered while monitoring.
• Similarly, the none (following all in our example) is indicative of the fact that none of the event IDs need to be excluded from monitoring. On the other hand, if you want to instruct the eG Enterprise system to ignore a few event IDs during monitoring, then provide the IDs as a comma-separated list. Likewise, specifying all makes sure that all the event IDs are excluded from monitoring.
• In the same way, you can also ensure that events generated by specific users on the target host are alone tracked by providing a comma-separated list of users to be monitored – for example, john,elvis. In our example however, all is specified, indicating that all users need be monitored.
• You can similarly indicate if specific users need to be excluded from monitoring. In our example however, none is provided to ensure that no users are excluded from monitoring.

Note:

The event sources and event IDs specified here should be exactly the same as that which appears in the Event Viewer window.  

On the other hand, if the Policy Based Filter flag is set to Yes, then a Filter list box will appear, displaying the filter policies that pre-exist in the eG Enterprise system. A filter policy typically comprises of a specific set of event sources, event IDs, and users to be monitored. This specification is built into the policy in the following format:

{Policyname}:{event_sources_to_be_included}:{event_sources_to_be_excluded}:{event_IDs_to_be_included}:{event_IDs_to_be_excluded}:{users_to_be_included}:{users_to_be_excluded}

To monitor a specific combination of event sources, event IDs, and users, you can choose the corresponding filter policy from the Filter list box. Multiple filter policies can be so selected. Alternatively, you can modify any of the existing policies to suit your needs, or create a new filter policy. To facilitate this, a Click here link appears just above the test configuration section, once the Yes option is chosen against Policy Based Filter. Clicking on the Click here link leads you to a page where you can modify the existing policies or create a new one. The changed policy or the new policy can then be associated with the test by selecting the policy name from the Filter list box in this page.

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency.
