SQL (Structured Query Language) is a domain-specific language used in programming. It manages the data stored in databases. With organizations getting more data-driven, SQL is the most sought-after programming language for managing databases. 

SQL enables users to access records or data in batches with just one single command. Thus, by using SQL queries, the user will not have to specify how the data should be retrieved.

Nowadays, most hackers try to exploit databases with the intention of stealing or modifying data. Whenever you attempt to log in to a website, the password stored in the database is brought up and compared with what you have typed into the system. 

While you can not see it, hackers take advantage of this by using SQL injection to extract sensitive data from organizations and individuals. It can result in the loss of crucial information, such as passwords, bank account information, and social security numbers. Therefore, learning SQL can help you make databases more secure.

SQL – Hacker’s Go-To Language:

  • Black hat hackers use SQL to develop hacking programs based on SQL injection.
  • Hackers use it to run unauthorized queries to obtain unhashed passwords.

Why is SQL Useful in Cybersecurity?

  • An understanding of SQL, its uses, and how SQL injection attacks, enables you to manipulate websites can be beneficial for cybersecurity professionals. 
  • Since SQL Injection is one of the top threats to web application security, security defenders will greatly benefit from the mastery of SQL.
