The overall security of SQL Server instances is a broad topic. Security breaches happen often, and, in most cases, they are resolved quickly, and the level of security is tightened, but the best and most desirable scenario is to avoid them entirely. This can be done by taking proactive actions in analyzing possible security risks and patching them before the least desirable scenario happens. With SQL Server environments being dynamic, there is an almost constant need for better security and management of SQL Server instances.

When it comes to using the SQL Server instance, a DBA must ensure no one unauthorized, or outside of the organization, should have any privileges that will allow him to change any SQL Server configuration. Preventing this scenario will provide an additional layer of security that will result in decreasing the level of SQL Server’s vulnerability and its exposure to malicious attacks.

Maintaining the security of dedicated SQL Server instances and its environment is the most important duty of any DBA. Various problems, including the unwanted external breaches, may arise that could heavily impact the safety of a SQL instance and could potentially harm the company as well.

TempDB is a section of SQL Server instance that is used to store temporary data of tables, views, objects, functions, and indexes and is often overlooked in the grand scheme of performance optimization; hence it is left on default by DBAs. It is not an overly complicated area, but in everyday DBA tasks, this area gets a little less attention. Leaving the TempDB configuration on default will not result in a production environment crash, but it will take a toll on the overall SQL Server performance and, in worse case scenarios, jeopardize contingency plans in disaster recovery scenarios. With a little optimization management and customization in key areas, the aforementioned scenarios can be averted, and the performance of a SQL Server instance increased to mitigate the toll.

SQL Server Management Studio (SSMS) is an integrated environment for managing SQL Server instances. By using SSMS, one could access, configure, manage, administer, and develop all components of SQL Server.

Daily obligations in a DBA life can be time-consuming, depending on the type of tasks needed to maintain a SQL Server. Problems that can occur range from SQL Server instance configuration to the actual databases it is facilitating. Allowing these issues to happen and persist can interfere with the overall performance of an environment and take away much needed time that can be spent differently.

Maintaining a SQL Server environment can be a time-consuming task for every DBA. Problems can occur in various scenarios and each of those scenarios can hinder the overall performance of an environment.

As known, the Microsoft SQL Server is a relational database management system with the function of storing and retrieving data requested by other corresponding software applications.

To a proactive DBA, it might be of crucial importance to have its SQL Server instances regularly checked for possible issues as there certainly are the multiple benefits to be gathered from this practice. At the long run and when not addressed timely, these issues might cause a major disaster, slowing or stoppage of production SQL Servers causing an enormous headache to everyone involved, and not to mention the cost of having the production environment down for a few hours or, god forbid, days.
