DB

Definition

DB, short for Database, is a structured collection of data that is stored and accessed electronically. Databases are managed by Database Management Systems (DBMS) which allow for the creation, querying, updating, and administration of data. They are critical components in software applications, enabling efficient data storage, retrieval, and manipulation.

Secure Settings Example

# Example of a secure PostgreSQL configuration
listen_addresses: 'localhost'  # Restrict access to localhost
ssl: 'on'                      # Enable SSL for encrypted connections
password_encryption: 'scram-sha-256'  # Use strong password encryption
pg_hba.conf:
  - type: 'host'
    database: 'all'
    user: 'all'
    address: '127.0.0.1/32'
    method: 'scram-sha-256'  # Use SCRAM for authentication

Insecure Settings Example

# Example of an insecure PostgreSQL configuration
listen_addresses: '*'  # Allows connections from any IP address
ssl: 'off'             # Disables SSL, allowing unencrypted connections
password_encryption: 'md5'  # Uses weak password encryption
pg_hba.conf:
  - type: 'host'
    database: 'all'
    user: 'all'
    address: '0.0.0.0/0'
    method: 'trust'  # No password required for authentication
