MSSQL Security Best Practices

MSSQL security is a top priority for any business that relies on a database management system (DBMS) like Microsoft SQL Server (MSSQL). Cyber threats are becoming increasingly sophisticated, and protecting your data from unauthorized access, data breaches, and other cyber attacks is essential. In this article, we’ll discuss some MSSQL security best practices that can help you protect your data from cyber threats.

Keep your MSSQL server up-to-date.

Keeping your MSSQL server up-to-date with the latest security patches is one of the most important security best practices. Cybercriminals are constantly looking for vulnerabilities in software and applications, and the best defense is to keep your software up-to-date. Microsoft regularly releases security updates for MSSQL, and it’s important to apply these updates as soon as they become available.

Example: In 2017, a ransomware attack known as “WannaCry” targeted businesses around the world, exploiting a vulnerability in Windows operating systems. Microsoft had released a patch to fix this vulnerability months before the attack, but many businesses had not applied the patch, leaving their systems vulnerable.

Use strong passwords and authentication in MSSQL Security.

Using strong passwords and authentication is another important MSSQL security best practice. Weak passwords are easy for cybercriminals to guess or crack and can give them access to your sensitive data. It’s important to use strong passwords that include a combination of upper- and lower-case letters, numbers, and symbols. Additionally, enabling multi-factor authentication can add an extra layer of security to your MSSQL server.

Example: In 2019, a data breach at Capital One exposed the personal information of more than 100 million customers. The breach occurred because the attacker was able to guess the administrator’s weak password and gain access to Capital One’s data stored in the cloud.

Restrict user access in MSSQL Security

Restricting user access to your MSSQL server is another important security best practice. Only authorized users should have access to the data stored on your MSSQL server. It’s important to define and enforce strict access controls, limiting user access to only the data they need to do their job. Additionally, it’s important to monitor user activity to detect any unauthorized access attempts.

Example: In 2020, a group of cybercriminals gained access to Twitter’s internal systems by using stolen employee credentials. The attackers were able to access the company’s internal tools and gain access to high-profile Twitter accounts, which they used to promote a cryptocurrency scam.

Encrypt your data.

Encrypting your data is another important MSSQL security best practice. Encryption scrambles your data so that it can only be read by someone with the correct decryption key. This makes it much harder for cybercriminals to access your sensitive data, even if they are able to breach your MSSQL server.

Example: In 2013, Target suffered a data breach that exposed the personal information of millions of customers. The breach occurred because cybercriminals were able to access Target’s payment system using stolen credentials. If the data had been encrypted, it would have been much harder for the attackers to access the

Implement password policies

Enforce password policies within your MSSQL server to ensure that users are creating strong passwords. Configure settings such as minimum length, complexity requirements, and expiration periods.

Enable two-factor authentication (2FA)

Add a second layer of protection by implementing 2FA for your MSSQL server. In addition to their password, users are required to give a secondary authentication method, such as a temporary code texted to their mobile device.

Use dedicated accounts

Avoid using shared or generic accounts for accessing the MSSQL server. Instead, create dedicated user accounts for each individual with appropriate access levels and privileges.

Regularly update passwords

Users should be encouraged to regularly update their passwords. Decide on a password expiration policy and remind users to change their passwords every so often.

Limit login attempts

Set account lockout parameters to restrict the number of unsuccessful login attempts. By locking off the account after a certain number of unsuccessful login attempts, helps against brute-force assaults.

Monitor and log authentication attempts

Enable auditing and monitoring of authentication events in your MSSQL server. Regularly review the logs for any suspicious activities or unauthorized access attempts.

Educate users

Inform your users of the value of secure passwords and reliable authentication procedures. Encourage them to be watchful while sharing their login information and to report any security issues right away.
