Database Security Basics

Why Database Security Matters

Key Security Measures

• Authentication — strong passwords, separate user accounts.
• Authorization — least-privilege GRANTs.
• Encryption — protect data at rest and in transit (SSL).
• Prepared statements — prevent SQL injection.
• Backups — recover from attacks or failures.

Summary

• Security = authentication, authorization, encryption, injection prevention, backups.
• Give minimum privileges and always use prepared statements.

Database Security क्यों ज़रूरी

मुख्य Security उपाय

• Authentication — मज़बूत passwords, अलग user accounts।
• Authorization — least-privilege GRANTs।
• Encryption — data at rest और transit में सुरक्षित (SSL)।
• Prepared statements — SQL injection रोकें।
• Backups — attacks या failures से recover।

सारांश

• Security = authentication, authorization, encryption, injection prevention, backups।
• Minimum privileges दें और हमेशा prepared statements use करें।
