Different Methods to Check Audit Logs on Windows Server 2016
Now let’s explore several methods you can use to check audit logs on your Windows Server 2016 system.
Method 1: Using Event Viewer
Event Viewer is a built-in Windows tool that allows you to view and analyze event logs on your system. To check audit logs using Event Viewer, follow these steps:
1. Press the Windows key + R to open the Run dialog box.
2. Type "eventvwr" and press Enter to open the Event Viewer.
3. In the Event Viewer window, navigate to "Windows Logs" and click on "Security."
4. The Security log will display all the audit events. You can filter the log by clicking on "Filter Current Log" on the right-hand panel.
5. Set the necessary filter parameters, such as event source, event ID, or time range, to narrow down the audit log entries.
6. Once you have applied the filters, the audit log entries that match your criteria will be displayed.
Pros:
– Event Viewer provides a user-friendly interface for viewing and analyzing audit logs.
– It allows you to filter audit log entries based on various criteria, making it easier to locate specific events.
– Event Viewer provides detailed information about each event, including the date, time, user, and event description.
Cons:

– The interface can be overwhelming for inexperienced users, and it may take some time to get familiar with its features.
Method 2: Using PowerShell
PowerShell is a powerful command-line tool that allows you to automate administrative tasks on Windows Server 2016, including checking audit logs. To check audit logs using PowerShell, follow these steps:
1. Open PowerShell by pressing the Windows key + X and selecting "Windows PowerShell" from the menu.
2. Use the following command to view the audit log entries:
"`
Get-WinEvent -FilterHashtable @{Logname=’Security’;} | Where-Object {$_.LevelDisplayName -eq ‘Audit Success’}
"`
This command filters the audit log entries to display only the successful audit events.
3. The PowerShell command will display the audit log entries matching your criteria, including the date, time, user, and event description.
Pros:
– PowerShell provides a flexible and powerful way to automate tasks, including checking audit logs.
– You can easily filter audit log entries using PowerShell commands, allowing you to focus on specific events of interest.
– PowerShell provides a script-based approach, making it easier to repeat and schedule audit log checks.
Cons:
– PowerShell commands can be complex and require some knowledge of scripting and PowerShell syntax.
– Incorrectly executed PowerShell commands can have unintended consequences, so caution must be exercised.
Method 3: Using Security Configuration and Analysis
Security Configuration and Analysis is a Microsoft Management Console (MMC) snap-in that allows you to analyze and configure security settings on Windows Server 2016. To check audit logs using Security Configuration and Analysis, follow these steps:
1. Press the Windows key + X and select "Run" from the menu.
2. Type "mmc" and press Enter to open the Microsoft Management Console.
3. In the MMC window, click on "File" and select "Add/Remove Snap-in."
4. Select "Security Configuration and Analysis" from the list of available snap-ins and click on "Add."
5. Click on "Finish" and then on "OK" to add the snap-in to the MMC.
Now let’s analyze the Security Configuration and Analysis log:
1. Right-click on "Security Configuration and Analysis" in the MMC and select "Open Database."
2. Provide a name for the database and save it with a .sdb extension.
3. In the list of available templates, double-click on "Security Template."
4. Select the desired security template and click on "Configure Computer Now."
The Security Configuration and Analysis log entries will provide information about security configurations and related events.
Pros:
– Security Configuration and Analysis provide a comprehensive view of security settings on Windows Server 2016.
– It allows you to compare current security settings with predefined security templates, helping you identify any deviations.
– Security Configuration and Analysis logs can assist in troubleshooting various security-related issues.
Cons:
– Security Configuration and Analysis requires some knowledge of security settings and templates to effectively analyze logs.
– Analyzing the logs may require understanding the context of specific security settings and their implications.
Method 4: Using Command Prompt
Command Prompt is a command-line tool that allows you to execute various commands and scripts on Windows Server 2016. To check audit logs using Command Prompt, follow these steps:
1. Press the Windows key + X and select "Command Prompt" from the menu.
2. Execute the following command to retrieve the audit log entries:
"`
wevtutil qe Security /c:1 /rd:true /f:text /e:root
"`
This command outputs the last log entry from the Security log in a text format.
3. The Command Prompt will display the audit log entry, including the date, time, user, and event description.
Pros:
– Command Prompt provides a lightweight and efficient way to retrieve audit log entries.
– It allows you to extract specific log entries by applying filters or querying specific log sources.
