What are the security features and best practices for securing MySQL databases

What are the security features and best practices for securing MySQL databases and protecting against common security threats, including SQL injection attacks, privilege escalation, unauthorized access, data breaches, and regulatory compliance requirements, and how do features like user authentication, access control, encryption, auditing, and network security measures such as SSL/TLS encryption and IP whitelisting help to safeguard sensitive data and prevent unauthorized access and data manipulation?How does MySQL handle transactions and concurrency control mechanisms to ensure ACID (Atomicity, Consistency, Isolation, Durability) properties and maintain data integrity in multi-user environments, and what are the isolation levels, locking strategies, and transaction isolation levels supported by MySQL, such as READ COMMITTED, REPEATABLE READ, SERIALIZABLE, and the use of row-level locking, table-level locking, and deadlock detection algorithms to prevent data corruption and maintain consistency in concurrent transactions?
