Benefits of SQL Server DBA Audit Trigger

Know the Pro and Cons of SQL Server DBA Audit Trigger before you apply it.

Database Administrators can apply, many Techniques for auditing the uses of SQL Server Database for Regulatory and Security Purposes. And few methods, in Designing SQL Server audit triggers.

For capturing, Data About whole Transactions and Modifications to a Database Table.

Pros of Audit Triggers

Triggers accept Recursion, Triggers are more recursive, when it is considered, for nesting, when they operate an action, that fires another trigger.

Triggers have the option to nested, up to 32 levels. A trigger is more nested, when it operates, an action that fires another example, of the trigger to fire.

We can use external code, as a trigger, by using CLR triggers. This Trigger select, the method of an assembly, that scripted in .NET for binding with the Trigger.

We can use Trigger, for Implementing, referential Integrity on databases. It’s Unfortunate, that it does not allow, the design of constraints. That is in between many different databases.

SQL Server Audit Triggers, offer DBA, the capability for tracking Database changes in harsh Level. This makes, them more Unique, for Implementing in Small SQL Server Environments.

That has to check in a Detail adaptive manner level.

Triggers are also, used for auditing, certain specific Database Object. As it was avoided by the complete introduction of objects. Not to mention, they can terminate Emails to DBAs, if they trace any issues with data manipulation language, and Data Definition language techniques, Or unauthorized, login trails.

We can call stored procedures and certain functions from a depth of Trigger.

When SQL Server Audit is a Good Option?

It works best when!

When it clear business Rules, and designed for triggers. When DBA have to trace, database modifications, in a simple and granular way.

In small Database Environments, that is without a tough transaction load.

What causes a Problem?

If Security measures are not, in place for preventing hazardous utilization of them.

In database Dashboards, that has big numbers of Data.

In Online Transaction processing, systems that have a big workload.

SQL Server Audit Trigger Cons

When we use BULK INSERT, for Inserting Data into a Table, triggers are not fired, until you attach FIRE_TRIGGERS, options your Bulk Insert Statement.

This is most important to know, because if you have triggers, on certain tables, as a part of the business logic.

Triggers add, overhead to certain DML statements and more trigger, but by definition, the DML statement does not, end until the trigger execution completes.

This can design a disaster in more production.

The issue, of utilizing a trigger, you can delete, the number of Rows, that need to audit table, that was designed when someone changes, information by ad-hoc query or add more logic, into the complete trigger code.

Recursive Triggers are harder, for debugging the nested Triggers.

If we use triggers, for enforcing referential integrity, you have to trigger, this has to disable, by users that have ALTER permission, on the table.

When we Process Triggers, upper to Database systems and they can make, they operate more Slower. In front, triggers become tough in Certain Environments. With Big, online transaction Process or other Environments with Big amounts of Data.

According to Experts, by using Audit Triggers, the business rules that organized with, it should have fully planned.

A trigger is a reactive Instance, as in expert words, it was made, to react to certain stimulation. A trigger has the option to miss-understood, their business Rules, and Regulations.

That planned poorly, but proper designing, these Rules, is more time consuming and in rare cases more Difficult.

We have another issue, when using triggers, that is they, every time has permissions, that users do not, which cause problems, when a user requires to pass, the audit Triggers in SQL Database.

Experts explained in a Detailed, way that how hazardous hackers, can use SQL Server, audit triggers, for Their Own Advantage. If many hackers know a machine that has made with Triggers, they may repeatedly Attack.

It for Designing, a diversion or to view how fast the DBA will respond and what security measures, experts take. While Triggers use auditing tools in Databases, they are not in a good match, for each system.

Recursive Triggers are more tough to Debug.

Till now, I have covered the best data about, the pros and cons of the SQL Server Audit Triggers, in upcoming articles, I will update more Data on it.
