SQL Server security has always been important. Protecting the enterprise data resources stored in SQL Server databases is arguably the prime responsibility of an organization’s DBAs. The performance and availability of mission-critical database applications quickly become irrelevant in the aftermath of a data breach. Data assets must be secured if they are to be used productively.
Remote work, which greatly expanded due to the COVID-19 pandemic, adds to security concerns and makes it more difficult to protect valuable databases. Potentially unsecured devices being used to access sensitive data present inviting new targets for hackers. There is no lack of cybercriminals who would like nothing better than to compromise your SQL Servers.
Some fairly recent examples illustrate the dangers your SQL Servers are under every day. Hacker campaigns such as Vollgar are affecting thousands of instances with malware designed to mine cryptocurrency. Malware infections can create backdoor access to SQL Servers like that seen in the Skip-2.0 exploitation tool. The tool allows remote attackers to use a “magic” password to connect to any account and hides its tracks by disabling logging while performing an intrusion.
Needless to say, these are the kinds of stories that give database teams nightmares. They need to accept the fact that their systems are potentially subject to malicious internal or external entities who want to compromise their data. Traditional hacking methods like brute force attacks and SQL injection are still used to take advantage of vulnerable systems.
This is a troubling state of affairs, but some remedies can help alleviate security concerns and enable team members to get a better night’s sleep. These best practices offer essential recommendations to increase the security of enterprise SQL Server databases.
What Can a DBA Do?
There are many ways in which a DBA can strengthen the SQL Server security landscape. With the right mix of configuration decisions and regular activities, system security can be substantially increased. Here are some of the things the database team can do to protect their SQL Servers more effectively.
A Tool for Enhanced SQL Server Security
A TechGenix webinar sponsored by IDERA and presented by Brien Posey and Elan Kol goes into more detail concerning the methods DBAs can use to strengthen SQL Server security using SQL Secure. This dedicated SQL Server security tool provides DBAs with valuable features to harden database defenses. Its features include:
DBAs interested in securing their SQL Servers should take the time to view the webinar and take advantage of the free 14-day trial of SQL Secure. Testing the full functionality of the product will demonstrate how it can help you protect your enterprise databases.
Ask any victim of a data breach if they wish they had taken stronger measures to prevent it. With the right tools and best practices, you can make it harder for hackers to gain access to your SQL Servers. It’s worth the effort.
