SQL Server 2019 Security Best Practices
In this sql server tutorial video we'll provide you with some of the SQL server security best practices. SQL Server security measures are some of the most frequent sql server interview questions, and these almost always come up when watching a sql server tutorial. Database security threats and security issues are a very serious topic and database security threats aren't something that should be overlooked - make sure to adhere to the database security best practices outlined in this video, though, and you should be good to go.
To crush database security threats, make sure to adhere your actions to three key areas known as the "CIA triad":
1) Confidentiality
2) Integrity
3) Availability
To keep your SQL server secure, keep an eye on:
1) OS security: regularly update your system with security patches, consider using a firewall and enabling only the necessary ports.
2) User security: use strong passwords for all of your users accounts, consider enabling a password security policy, and also dig into the password security options provided by SQL Server: these are "MUST_CHANGE", "CHECK_EXPIRATION", and "CHECK_POLICY."
3) Privileges: only grant necessary privileges to users, use the principle of least privilege, and also dig into SQL server roles to help delegate database privileges.
4) Monitoring: make sure to monitor the activity within your sql database instances by using SQL clients like Arctype, DbVisualizer or others and also monitor your databases manually: observe the error log and keep an eye on the creation and interaction of the objects within your sql database instance. Monitoring-related sql interview questions are amongst the most frequently asked sql database developer interview questions, so knowing sql interview questions and answers related to this issue will certainly help.
5) Upgrades: also, a good sql tutorial will also mention other sql basics: upgrades are crucial for your database and by making sure it's always up to date, you will lessen the risk of you falling victim to security threats.
