5 Ways to Protect Your MySQL Data Warehouse

Aggregating data from various sources can create a central warehouse. By analyzing and summarizing business data reports, data warehouses can help companies make informed, strategic decisions. Although data warehouses provide many conveniences, collecting this sensitive data into a separate system will bring security issues to the data warehouse. This article mainly introduces five tips in detail to tell you how to protect the MySQL data warehouse. It has certain reference value. Interested friends can refer to it. I hope it can help you.

If you choose to use a data warehouse, companies need to consider how to better protect internal information systems. Any compromise in data warehouse security will give intruders or cybercriminals an opportunity to destroy and leak business data such as sales, marketing, and customer information. This year's WannaCry ransomware incident also demonstrated this, and modern enterprises need to strictly avoid data crimes.

In data warehouses, the most common database management system should be the open source MySQL database. This article lists 5 tips to help users better protect the MySQL data warehouse.

1. Access restrictions

One of the ways to effectively protect the MySQL data warehouse is to only give access permissions to users who absolutely need it. By implementing role-based control, you can restrict some users' access to data warehouse information, such as viewing or operating database objects. In addition, some tables and schemas can only be accessed by specially defined roles in the warehouse database.

MySQL database administrators need to strengthen the implementation of security measures to limit individual users' operations on the data warehouse, including:

The number of queries allowed per hour for a single account;
The number of queries allowed per hour for a single account Number of updates;
The number of times a single account is allowed to connect to the server per hour;
The number of concurrent connections to the server for a single account.

If you want to use the information in the data warehouse to make important decisions, access to views or changes to MySQL warehouse data should only be given to key business personnel.

2. Create a password expiration policy

Password cracking tools are one of the main ways 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. Evidence shows that asking users to change their passwords frequently can cause them to become frustrated, leading them to simply create a simple password that is easily vulnerable to hackers. Therefore, you can choose a reasonable expiration time, such as six months before requiring users 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 to create a strong password every time.

3. File backup

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

MySQL has a large number of backup functions to help users quickly restore the database after a security incident. 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 quickly restored easily using special MySQL functions.

For remote backup, you need to choose a secure remote server to place the backup data, which will help avoid problems caused by fires, floods and hardware failures.

4. Update and installation of critical patches

Oracle, the developer of the MySQL system, will regularly release critical patches to solve security issues and help users update Own MySQL data warehouse. It is important that organizations maintain an update pace and install critical patches as soon as possible after they are released.

Sometimes, developers find flaws in existing software, and patches exist to fix those bugs. You can check all plans and past critical patch updates for MySQL here.

5. Use reliable data integration solutions

Since the MySQL data warehouse integrates information from multiple data sources in the enterprise, use reliable solutions Can be of great help. A good data integration platform can efficiently and securely send data source data to the MySQL data warehouse.

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

Integrate these five skills into MySQL data warehouse management, and your important business data can be fully protected.
