This article is about how to protect MySQL data warehouse. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

If you choose to use a data warehouse, enterprises need to consider how to better protect their internal information systems. Any compromise on warehouse security will give intruders or cyber criminals an opportunity, resulting in the destruction and disclosure of sales, marketing, customer information and other business data. The outbreak of WannaCry blackmail software incident this year also shows that modern enterprises need to strictly avoid data crime.

In the data warehouse, the most common database management system should be the open source MySQL database. This article lists five tips to help users better protect MySQL data warehouses.

1. Access restriction

One of the effective ways to protect MySQL data warehouses is to give access to only users who are absolutely needed. By implementing role-based control, you can restrict some users' access to warehouse information, such as viewing or manipulating database objects, as well as tables and schemas that allow access only to roles specifically defined in the warehouse database.

MySQL database administrators need to strengthen security measures to restrict individual users' operations to the data warehouse, including:

The number of queries allowed per hour for a single account

The number of updates allowed per hour for a single account

The number of times a single account is allowed to connect to the server per hour

The number of concurrent connections to the server from a single account.

If you want to use the information in the data warehouse to make important decisions, change permissions to access the view or MySQL warehouse data should be given only to key business people.

two。 Create a password expiration policy

Password cracking tool is one of the main methods for intruders to enter the database system. The use of MySQL provides users with an option to create their own password expiration policy and set the number of expiration days through the default_password_lifetime variable.

Users need to find the right balance when it comes to password expiration. The evidence suggests that requiring users to change passwords frequently can make them frustrated, causing them to create only a simple password that is vulnerable to hackers. So you can choose a reasonable expiration time, such as six months later, and then ask the user to create a new password to access the data warehouse.

It is also recommended that users use a password generator to access the data warehouse and create a strong password each time.

3. File backup

For any database system, the backup of MySQL data warehouse is a top priority. Natural disasters such as floods, fires, system crashes, hardware failures, and human errors all pose threats to business data.

MySQL has a large number of backup features to help users recover the database quickly after a security event. The most important thing is to establish a physical backup of the data warehouse to ensure that the original copy directories and files of the database information are foolproof. When needed, backup information can be easily and quickly restored using a special MySQL function.

For remote backup, you need to choose a secure remote server to store backup data, which helps to avoid problems caused by fires, floods, and hardware failures.

4. Update installation of key patches

Oracle, the developer of MySQL, regularly releases key patches to address security issues and help users update their MySQL data warehouse. It is important that enterprises maintain the speed of updates and install them as soon as possible after critical patches are updated.

Sometimes, developers will find defects in existing software, and patches exist to solve these errors. You can check all plans here, as well as key patch updates from MySQL in the past.

5. Use a reliable data integration solution

Because the MySQL data warehouse integrates information from multiple data sources in the enterprise, using reliable solutions can be of great help. A good data integration platform can send data from data sources to MySQL data warehouse efficiently and safely.

In addition, if you want to copy data from MySQL to the data warehouse of cloud platforms such as Redshift and BigQuery, the security of the data integration platform is also critical. A reliable platform can securely send important data from MySQL to the cloud to help with large-scale data analysis.
