And so, protecting its sensitive data is the highest concern for database admins. Let\u2019s discuss major 5 Common SQL server security issues and ways to avoid them.<\/p>\n<h4>5 Security Issues in the SQL environment<\/h4>\n<p>Seasoned SQL DBAs are very much aware of the security priorities of the SQL environment. But it is really a challenging task for new DBAs. So, we will give an overall idea of the SQL security issues, how they occur, and how to mitigate such issues.<\/p>\n<h4>Simple Tips for the Security of SQL Database<\/h4>\n<ul>\n<li>Take steps to make your physical environment secure.<\/li>\n<li>Protect your network.<\/li>\n<li>Allow permissions and accesses only to those who need them.<\/li>\n<li>Remove unwanted services and features.<\/li>\n<li>Install latest updates and patches without fail.<\/li>\n<\/ul>\n<p><strong>We will discuss these steps in detail now:<\/strong><\/p>\n<ol>\n<li><strong>Securing the Physical Environment:<\/strong><br \/>\nUsers usually forget to consider the physical security of SQL Server. This increases security threats considerably. The servers should be accessible only to the people who are dealing with them. Thus, you can ensure the physical security of the sensitive SQL data.<\/li>\n<li><strong>Protecting the Network:<\/strong><br \/>\nTo protect your network from virus attacks you should install an updated antivirus software. You should have firewalls installed too. And you should consider changing the default TCP\/IP ports because standard port numbers are known to all.<\/li>\n<li><strong>Providing optimum permissions only:<\/strong><br \/>\nSQL may be saving your database files, log files, etc. in different locations. So, it is important that you protect all these folders and files from unauthorized accesses. Access to these locations must be given according to job requirements only.<\/li>\n<li><strong>Avoid unwanted features:<\/strong><br \/>\nUnnecessary features, settings, services, and add-ons may cause security issues in SQL environment. So, it is suggested to review every feature and setting before deploying them. Use only those services that are really required for your smooth working.<\/li>\n<li><strong>Update software regularly:<\/strong><br \/>\nMicrosoft releases updates, patches, and service packs regularly after bug fixes. These updates must be installed so as the SQL Server is protected against latest security issues and viruses.<\/li>\n<\/ol>\n<h4>What if your SQL Server has already become inaccessible?<\/h4>\n<p>Yes. Despite all your precautions, your SQL data can be inaccessible or corrupt.<\/p>\n<p>Hence, we recommend you to always take backups for your SQL database and save it to different locations that are outside your common network. You can also take advantage of the third-party tool \u2013 SQL Recovery. This <a href=\"https:\/\/www.kerneldatarecovery.com\/sql-recovery.html\">SQL Recovery<\/a> tool is strongly recommended for users who face SQL database issues like corruption and inaccessibility of database files.<\/p>\n<p align=\"center\"><a class=\"dl\" href=\"https:\/\/www.kerneldatarecovery.com\/dl\/dl.php?id=77\" onclick=\"dataLayer.push({'event': 'TrackEvent', 'eventCategory': 'Download', 'eventAction': 'SQLRecovery', 'eventLabel': 'BlogDLid=77'});\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-1659 noshadow\" src=\"https:\/\/www.kerneldatarecovery.com\/blog\/wp-content\/uploads\/2018\/06\/dl-btn-new.png\" alt=\"Download Now\" width=\"160\" height=\"49\"><\/a><\/p>\n<h4>Summary:<\/h4>\n<p>Users are strongly recommended to take proper <a href=\"https:\/\/www.kerneldatarecovery.com\/blog\/a-checklist-for-monitoring-sql-server-managing-the-database-effectively\/\">monitoring for protecting their critical SQL database<\/a> against all vulnerabilities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Security has always been the hottest topic for professionals who are working with IT industry, especially for those who are working with SQL Server.
