MySQL（全稱為My Structured Query Language）是一種流行的開源關(guān)系型數(shù)據(jù)庫管理系統(tǒng)，應(yīng)用于許多網(wǎng)站和應(yīng)用程序。然而，隨著網(wǎng)絡(luò)安全威脅的增加，數(shù)據(jù)庫的安全性也變得越來越重要。

One possible security threat is an attacker attempting to delete the entire MySQL database, also known as "drop database". In order to prevent this kind of attack, a common method is to restrict access to the MySQL server to trusted IP addresses only.

# Example configuration for MySQL to only allow connections from specific IP addresses
# /etc/mysql/mysql.conf.d/mysqld.cnf
bind-address = 127.0.0.1  # Only allow connections from localhost by default
skip-networking  # Disable networking altogether if possible
# This is where you would add additional IP addresses to allow connections from
# Replace "x.x.x.x" with the desired IP address
# Allow IP address 192.168.1.100 to connect
bind-address = 192.168.1.100  
# Allow IP address 10.0.0.24 to connect
bind-address = 10.0.0.24

通過限制可以訪問MySQL服務(wù)器的IP地址，可以大大減少潛在的安全風(fēng)險。管理員應(yīng)該僅允許可信的IP地址連接到數(shù)據(jù)庫，并始終保持數(shù)據(jù)庫系統(tǒng)的更新和安全。
