In this post, readers will get to know about some important security and compliances guidelines/recommendations that are highly important for successfully running SQL Server.
Are you looking for few good recommendations in terms of security and compliances for SQL Server database? You’ve come to the right place. Having knowledge of these compliances can help you ensure enhanced security of your SQL server. Additionally, it can also be helpful in the recovery and restore procedure such as a MDF repair process. Keep reading for more information.
Security and Confidentiality Guidelines:
- Make sure to set up an environment that is easy to monitor and secure.
- Make sure to conduct regular event auditing whether events happen to be external, internal, invoked by users, or by the system itself.
- Enforce rules and regulations that will restrict unauthorized access. Make sure rules are applicable to tables, databases, logins, and other server objects too.
- Be sure to ensure confidentiality and security of data by implementing necessary limitations/permissions.
Compliance regulations require that administrators perform periodical analysis and audition of events associated with security. Be sure to document any changes that may have happened with access to database or server objects. Also, every single user of the database including administrative personnel must be given equal treatment while performing audits. Therefore, every member must provide information to auditors.
Hardware/Software Related Compliances
It is recommended to use only verified hardware as well as software for accessing information in an SQL server. Omissions related to high security configurations like logins, default network settings, and passwords can be exploited by attackers.
If there are any default security parameters for SQL server, make sure to modify them. Do not use the mixed mode for authentication. The mixed mode enables authentication for both SQL server and Windows. It is recommended switching only to Windows authentication. What sets Windows password policy apart from SQL Server authentication is the login lockout. If you fail to login successively for a number of times in Microsoft, login gets locked and cannot be used any further. But, SQL server authentication cannot detect brute-forced attack attempts. As a matter of fact, it’s optimized for handling several failed login attempts. Therefore, it is advised to disable SA login for security purposes.
Disabling Important Services/Features
If there are any services or features in the SQL server that are not important for running the database system properly, do disable all of them. Many times server components require additional modifications and setup by changing their default settings. When you disable those components, you can avoid a number of security issues. Make sure to install only those components that you need. Avoid installing everything else.
Checking System Configurations Periodically
Do keep on checking and verifying the security configuration settings in SQL Server from time to time. Do check all the previously defined permissions and rules. If some changes have not been documented, it could potentially lead to security problems. Therefore, it is highly recommended to keep checking system configurations from time to time.
