What are the security differences between NoSQL and SQL databases?

SQL databases typically use structured schemas and support ACID transactions, which enhance data integrity and security. NoSQL databases, on the other hand, are more flexible with schema design but may lack some built-in security features.

Can you explain what ACID transactions are?

ACID stands for Atomicity, Consistency, Isolation, and Durability. These properties ensure reliable processing of database transactions, making SQL databases generally more secure for critical applications.

Are NoSQL databases less secure because they are schema-less?

Not necessarily. While NoSQL databases are schema-less, they can implement security measures like access controls and encryption. However, the lack of a fixed schema can lead to potential vulnerabilities if not managed properly.

What are some common security practices for NoSQL databases?

Common practices include implementing strong authentication, using encryption for data at rest and in transit, and regularly updating software to patch vulnerabilities.
