You work hard to grow your business, but what
if someone tries to sabotage it? Cyberattacks are on the rise, and they can
cost you time, money, and reputation.
Data breach are common issues now, especially for big corporations that make
the headlines. However, small and medium enterprises (SMEs) are also affected
by this problem, even if they don't get much media attention.
Here are some best practices to enhance security and protect sensitive
information:
Access Control:
· User Privileges: Assign minimal privileges to database users.
Only grant necessary permissions (e.g., SELECT, INSERT, UPDATE, DELETE) based
on their roles.
· Strong Passwords: Set strong passwords for database users.
Avoid using default or easily guessable passwords.
· Database Encryption: Consider encrypting sensitive data at the
application level before storing it in the database.
Backup Security:
· Secure Backups: Ensure that backups are
stored securely. Limit access to backup files and encrypt them if possible.
Database Configuration:
· Database Hardening: Follow best practices for securing the database
server configuration. Disable unnecessary features and services.
· Audit Logging: Enable audit logging to track database
activity. Monitor logs for suspicious behavior.
Application Security:
· Parameterized Queries: Use parameterized queries or prepared
statements to prevent SQL injection attacks.
· Input Validation: Validate user input to prevent malicious data
from being inserted into the database.
· Escape User Input: Escape special characters to avoid unintended
SQL execution.
Data Encryption:
· Field-Level Encryption: Consider encrypting sensitive fields (e.g., credit card numbers, passwords) within the database.
Remember that security is an ongoing process,
and staying informed about the latest security practices is essential.
