There are many reasons for implementing auditing on an NT Server. First, it is important that you be able to verify that only authorized people can access the information on your network. One of the best ways to track this information is to audit logon and logoff attempts. A large number of failed logon attempts will alert you to the fact that a user may be trying to guess a password. One of the best security measures is the audit log. Though it technically won t prevent unauthorized access, auditing a system can be used to determine how an illegal activity occurred, and can also serve as a deterrent. In this section, we ll look at how to generate an audit trail for specific objects and how to manage the audit information once it s available.

On a Windows NT Workstation or Server, there are two major steps to activate auditing. First, the auditing feature must be enabled for the object type you wish to examine. This makes the second step actually setting specifics on which actions to audit possible. To enable the auditing function, you must have the Access the Audit Information user permission. (Permissions will be described in detail later in this chapter.) To turn on auditing, follow these steps: 1. Select Start | Programs | Administrative Tools | User Manager for Domains. 2. Select Policies | Auditing and turn on the various available auditing options. You ll see the following dialog box:

You can enable some types of auditing simply by placing a check mark in the appropriate box. For example, to store logon information, nothing more must be done. For each type of event, you can choose to audit successes, failures, or both. You should always record any changes to the audit log itself to prevent users from turning off the audit log, performing some actions, and then restarting the log. Additionally, a good general guideline is to always audit at least logon failures. Other auditing options require you to specify which objects and actions are recorded in the log. One example is the File and Object Access option. Assuming that this feature is enabled in User Manager, you can right-click any file or folder that resides on an NTFS volume and click Auditing in the Security tab. You can then set your auditing permissions on the screen that appears:

1. Open Event Viewer in the Administrative Tools program group. 2. To view the Security log, click Log and select Security. 3. To view further information on a specific item, simply double-click it on the list. This will show you details about the specific action, as shown in this example:
Often, you may be searching for only specific information in a very large event log. Manually looking through the list for items of interest can be quite tedious. Fortunately, there s a better way. If you re searching for specific information, such as failed logon attempts from a single machine, you can apply a filter. The filter affects only the display of data in Event Viewer it does not delete any data. In the following example, we ll search for failed logon attempts on the local server. This example assumes that you have enabled the Logon and Logoff attempts option in the Audit Policy dialog box. (Refer back to the Enabling Auditing section.) 1. Open Event Viewer from the Administrative Tools program group.

2. Select View | Filter Events. You ll see the following dialog box:
3. After you select the types of items you want to search for, click OK. This will automatically restrict the display of items to those that meet the criteria you specified in the filter. 4. To remove the filter, simply select View | All Items. It is a good idea to change the default options for Windows NT Event Log. The default is for the log files to be set to 512K and for events to be overwritten only after a certain number of days. On highly active systems, the logs may become full very quickly. Therefore, it is a good idea to increase the log files and choose the Overwrite Events As Needed option. It is important to audit only information that you feel will be useful. If you audit all successful accesses to a specific share, for example, you ll find your event log growing out of control. Also, auditing will decrease system performance. Remember, enabling any security option will require some tradeoff.
