Security Best Practices for azurerm_mssql_server_security_alert_policy

There are 3 settings in azurerm_mssql_server_security_alert_policy that should be taken care of for security reasons. The following section explain an overview and example code.

Ensure to configure at least one email address for threat alerts

It is better to configure at least one email address for threat alerts. SQL Server is able to send alerts for threat detection via emails and it could support us to notice the incident on time.

Ensure to enable all threat alerts

It is better to enable all threat alerts. SQL Server provides useful alerts including SQL Injection, vulnerabilities, access anomalies, and data exfiltration.

Ensure to enable to send an alert email to owners

It is better to enable to send an alert email to owners to take quick actions by any critical incident on time.

Parameters

• disabled_alerts optional - set of string
• email_account_admins optional - bool
• email_addresses optional - set of string
• id optional computed - string
• resource_group_name required - string
• retention_days optional - number
• server_name required - string
• state required - string
• storage_account_access_key optional - string
• storage_endpoint optional - string
• timeouts single block
  • create optional - string
  • delete optional - string
  • read optional - string
  • update optional - string

Tips: Best Practices for The Other Azure Database Resources

In addition to the azurerm_mariadb_firewall_rule, Azure Database has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.

azurerm_mariadb_firewall_rule

Ensure database firewalls do not permit public access

It is better to restrict IP address ranges that can access the database by firewall rules. If both start_ip_address and end_ip_address are set to 0.0.0.0, it blocks connections from the Internet and accepts connections from all Azure datacenter IP addresses.

azurerm_mariadb_server

Ensure that access to Azure SQL Database is restricted

It is better to disable public access to the database to avoid unwilling communications with unknown services if not required.

azurerm_mssql_database_extended_auditing_policy

Ensure to configure retention periods of database auditing to enough duration

It is better to configure retention periods of database auditing to enough duration. It would be better to set greater than at least 90 days.

azurerm_mssql_server

Ensure to enable auditing on Azure SQL databases

It is better to enable auditing on Azure SQL databases. It helps you maintain regulatory compliance, monitor the activities indicating unexpected incidents or suspected security violations.

azurerm_mysql_firewall_rule

Ensure database firewalls do not permit public access

It is better to restrict IP address ranges that can access the database by firewall rules. If both start_ip_address and end_ip_address are set to 0.0.0.0, it blocks connections from the Internet and accepts connections from all Azure datacenter IP addresses.

azurerm_mysql_server

Ensure to disable public access to database

It is better to disable public access to the database to avoid unwilling communications with unknown services if not required.

azurerm_postgresql_firewall_rule

Ensure database firewalls do not permit public access

It is better to restrict IP address ranges that can access the database by firewall rules. If both start_ip_address and end_ip_address are set to 0.0.0.0, it blocks connections from the Internet and accepts connections from all Azure datacenter IP addresses.

azurerm_postgresql_server

Ensure to disable public access to database

It is better to disable public access to the database to avoid unwilling communications with unknown services if not required.

azurerm_sql_firewall_rule

Ensure database firewalls do not permit public access

It is better to restrict IP address ranges that can access the database by firewall rules. If both start_ip_address and end_ip_address are set to 0.0.0.0, it blocks connections from the Internet and accepts connections from all Azure datacenter IP addresses.

azurerm_sql_server

Ensure to enable auditing on Azure SQL databases

It is better to enable auditing on Azure SQL databases. It helps you maintain regulatory compliance, monitor the activities indicating unexpected incidents or suspected security violations.
