Today, most corporate IT environments trust and are looking forward to investing in Microsoft SQL Server for transaction processing, business intelligence, and performing analysis on applications. It has known to be a great solution for data-intensive enterprises as it enables them to store and manage a large amount of sensitive or personal data with efficient permission management tools and access controls.
With so many advantages, there also comes a worry of being under constant threat as it holds a large amount of sensitive data that malicious hackers look forward to.
In this post, we have highlighted some of the best practices and monitoring tools that can enhance your SQL Server security and protect your data at all times.
What is SQL Server Security?
There are a dozen of database management software available online, yet Microsoft SQL Server is a top choice due to its in-built security features and functioning.
Microsoft SQL Server is a reliable relational database management system (RDBMS) that helps store and retrieve data as per the request. It has a user-friendly installation interface that makes it easier for users to install and secure data storage. Microsoft SQL Server also supports SQL programming language that helps various database administrators (DBAs) and other IT professionals to easily manage and query the data.
They also provide many permission management tools with access controls that help keep sensitive information safe and secure. It supports sophisticated encryption algorithms making it difficult for attackers to break the security layers and access crucial data.
Security of SQL Server is the primary responsibility of the database administrators. The server was designed with the capability and features to encrypt data, protect it from theft, limit access and authorization, and more.
Apart from maintaining security, it also enables you to maintain data integrity and consistency. Any individual with good knowledge and skills in SQL Programming language can run the server, make maximum out of its vital features, and improve performance.
The server is available in various editions, each having different functionality. Thus, customers can choose the right one from a wide range of options as per their budget and requirement. SQL Server is not a simple database engine but provides a variety of services, tools, and applications to improve overall results.
Why You Should Choose SQL Server
Here are a few reasons that most companies trust and choose SQL Servers over other database management software:
- Data Security SQL Server supports various features like encrypted communication over SSL/TLS, Transparent data encryption (TDE), and Windows Data Protection API (DPAPI) that protect your data and maintain proper security. It is completely in the hands of the database administrator to configure the above-listed features and address the security requirements of your applications.
- Optimizes Data Storage With a SQL Server, you do not have to look for duplicate data stored within your database while working on multiple computers. SQL Server provides integrity that helps in maintaining data accuracy. It also supports Microsoft’s proprietary language – Transact-SQL (T-SQL), that aids in programming queries and commands. SQL Server composes several other elements, including SQL Server Database Engine (manages processing and data storage) and Tabular Data Stream (connects SQL Server clients to database servers).
- Easy to Install and Provides Automatic Updates No special toolkit is required to run the server. The installation process is simple and cheap compared to other DBMS. Also, it supports automatic update features, thus reducing manual work.
A Quick Overview Of SQL Server Security
Poor database server security can cause too many data breaches. Thus, it is a must to invest in a server that supports powerful security features like Microsoft SQL Server. It supports Windows Authentication and SQL Server Authentication options. Also, it comprises various permission management tools.
Another advantage of SQL Server is that it supports multiple encryption options, such as Secure Sockets Layer (SSL), Transparent Data Encryption (TDE), Backup Encryption, etc. Yet, many organizations raise the issue of experiencing SQL database vulnerabilities and attacks.
To protect SQL Server security, one must understand the potential threats and then take action to reduce the attacks.
SQL Server Security Best Practices
Default security settings can leave your servers vulnerable to attacks. Here are a few practices that all database administrators must adopt to reduce the risk and protect data against malicious attacks.
- Run Multiple Security Audits Failed server logins, changes to configurations, or restricted database objects are a few signs that someone is trying to hack or attack your server. Thus, make sure to conduct regular security audits to prevent potential attacks and perform analysis on the possible breaches. Try auditing user logins, SQL Server Auditing, Schema changes, etc., to improve the health of your database.
- Create a Strong Password Policy Attackers find it difficult to crack strong passwords. Thus, make sure your password is a combination of numbers, uppercase/lowercase letters, and special characters. Also, make it long with a minimum of 10 characters. Avoid easy-to-guess passwords and keep changing them from time to time. Thus, making it difficult for attackers to crack one.
- Allow Minimal Privileges It is best to grant privileges and permission to the least operators and administrators in your work environment. Determine which accounts must be allowed to run by a specific database service. Domain user account, Active Directory managed service account, Network service account, and Local service account are a few accounts one can have for SQL Server services.
- Introduce a Database Backup Strategy Maintaining a regular backup of your SQL database and storing it in different locations will always keep your business safe from huge losses. Even after so much security, if the attacker manages to damage your server, you can recover your data and tackle SQL database issues. While creating backups, remember to encrypt all your files and data.
- Invest in SQL Monitoring Tools Install SQL monitoring tools to protect your database from frequent attacks. By adding these tools, you can keep track of changes made to the server settings and scall all the database application processes. Further, you can also timely detect errors and address performance issues.
