Database security is the protection of data stored in a database from unauthorized access, breaches, data corruption, and other security threats. It involves implementing measures such as access control, authentication, authorization, encryption, auditing, and secure coding to ensure the confidentiality, integrity, and availability of the data. Role-based access control simplifies user privileges, while data masking obfuscates sensitive information. Regular backups and recovery plans mitigate the risks of data loss or corruption. Vulnerability management helps identify and address potential weaknesses. Database security is crucial for safeguarding sensitive data and maintaining the trust of users and stakeholders. By implementing robust security measures, organizations can effectively protect their databases and mitigate security risks.

10. Imfortance
 If the intellectual property gets stolen,
then it becomes impossible to maintain
your competitive advantage.
 A breach of database security causes
damage to the reputation of your brand.
 Some business will stop to operate if
there is a breach.
 There are penalties or fines imposed in
case of a non-compliance.

11. It is a challenging and complex thing to incorporate total
database security. This will involve a range of practices
and information security technologies. If the database is
assessable easily then it makes it more vulnerable to
security threats. If the database is invulnerable then it
becomes difficult to access it. This gives rise to proper
database security measures.
