There are many errors users often encounter while dealing with SQL Server environment. One such error commonly seen is SQL Server audit failed to access the security log in the database. With the help of this write-up, we will take a look at the common causes for the error and also how this error can be resolved using professional approaches. But first, let’s learn a little about the error first and know why it occurs. 

SQL Server Audit Failed to Access the Security Log – Error Explained

When we talk about the error, it simply means that the SQL Server database is configured to record the audit events in the Windows Security log; however, due to insufficient permissions, it cannot write them. Because of this reason, the SQL Server might fail to store the audit records related to user activities, user logins, or even security-related activities. To simplify the definition of the error, it means, that the SQL Server engine tried to write a security audit entry but it was blocked due to insufficient or missing permissions in the database. 

Now, there can be various other reasons for the occurrence of this error. We will now take a look at the other reasons as well and try to find the best solutions that will help resolve them. 

Common Reasons for Audit Failed to Access Security Log in SQL Server

Here are some of the common causes for the error that can affect a user’s day-to-day work, further leading to bigger challenges. 

  • One reason for the error to occur is the missing permission to generate the security audits in the database. Due to this reason, the audit fails in the database. 
  • The next reason is the incorrect SQL Server service account. In cae the account doesn’t have proper permissions, or the account has been recently changed, the SQL Server will not be able to record audit changes. 
  • If the Windows Security log reaches its maximum size and the settings are configured not to overwrite the older records, the SQL Server will fail to write the newer record in the log. 
  • Another common reason to this error is the misconfigured settings of the SQL Server audits. This might include incorrect audit specifications and also the conflicts between the audit configurations. 

These are some of the common reasons that can lead to the audit failed to access the security log error in the SQL Server database. We will now take a look at how this error can be resolved in a professional and safer way. 

How to Fix Audit Failed Error in SQL Server Database?

We will now take a look at some of the best troubleshooting ways that can help with resolving the error in a much secure and precise way. We will understand and learn these methods one by one for better understanding. Beginning with the first method, let’s see how it works and how effective it is. 

Method 1: Grant Necessary and Required Audit Permissions

As we read earlier, one of the causes for the error is due to missing or insufficient permissions in the database. To resolve this issue, it is optimal to grant all the required and crucial permissions to the database. In this method, the database administrators should assign the Generate Security Audit access to the SQL Server Service account. With the allowed privileges, the SQL Server engine will be able to record and access audits without any issues. 

Method 2: Verify the SQL Server Service Account

The next method to resolve the issue is to verify the SQL Server service account under which the database is running. Now, here are the things the database administrator must keep in mind while verifying the service accounts:

  • The SQL Server Service account exists and is active.
  • It has appropriate system privileges for accessing the security logs.
  • The SQL Server Service account is not disabled or restricted. 

By verifying these three, database administrators can resolve the issue if caused by an incorrect SQL Server service account. 

Method 3: Using a Professional Utility to Keep Records of Security Log in SQL Server

When the SQL Server audit fails to access or record the log in the database, the users and database administrators often encounter issues like data changes and manipulation within the database. In such situations, it becomes necessary for users to track which user made which changes in the database to minimize the risk of data breaches or data manipulation. 

For this, we suggest using a professional SQL Log Analyzer Tool to track user activity in the SQL Server database. With the help of this advanced utility, users can easily check who manipulated data using commands like INSERT, UPDATE, or DELETE in the database.

Here are the steps to use the tool easily in a hassle-free way:

  1. Install and launch the suggested software. Click on the Open button to add the (.ldf)/(.mdf) file.
  2. Choose the Online DB option and enter the Server Name and Authentication. 
  3. Once the scanning is completed, all the translation details with number of DELETE , INSERTS and UPDATES will be displayed on the screen.
  4. Preview data and select the data for export. Click on the export button. 
  5. Use the provided filters to select the desired data for export and select the destination where you want your data to be exported. 
  6. Click on the Export button to finally export the data. 

With the help of these steps, users can easily track the changes made in the database, even if the SQL Server engine is not able to record the changes completely. Moving on to the next method, let’s take a look at how it can help users efficiently. 

Method 4: Check and Validate Windows Security Log Capacity

This is another troubleshooting method that allows users to resolve the issue in a much better and convenient way. The error might have occurred due to Windows Security log reaching its maximum storage capacity, further being unable to record new data. 

Database administrators can check the storage limit and further increase the log size to fix the issue. This helps prevent audit records from failing due to limited storage. 

Conclusion 

With this article, we have learned about the SQL Server Audit failed to access security log in the database. This error restricts the users from checking the log records. Furthermore, it stops SQL Server engine from recording new transactions due to limited space and other issues. We have listed the common reasons for the occurrence of this error. Lastly, we have suggested best ways that can help the users resolve this error in a secure and quick way. We have mentioned both manual and professional solutions.
