Database Security Best Practice

Database security best practices you must know

Database security can safeguard your business from cyberattacks and prevent financial loss, brand erosion, reputation damage, and non-compliance with government regulations. What are some of the best practices for database security?

  1. Separating your database servers

    Web servers are more vulnerable to cyberattacks due to their public accessibility. If your database server runs on the same machine, it may leave your data open for unauthorized access, therefore compromising your information.

    You can prevent this from happening by using a separate physical machine for your database server. This way, you can place specialized security measures to secure your databases further.

  2. Using web application and database firewalls

    Firewalls protect your database by denying access to traffic and preventing outbound connections. They are your first line of defense against various attacks, only allowing specific applications or web servers with authorization.

    You may use different firewalls, including packet filter, stateful packet inspection (SPI), or proxy server. Make sure to configure and keep your firewall updated to protect your database against new cyberattack methods.

  3. Securing your database user access

    Another simple way to secure databases is to limit user access. If possible, go for the lowest possible number of authorized people, allowing only administrators, IT workers, and other managers to have access.

    You can further secure your system by encouraging your employees to use strong passwords, limit login attempts, and assign roles.

  4. Updating your operating systems regularly

    Contrary to popular belief, securing databases is quite simple. If you regularly update your OS and software, you are already protected from recently discovered vulnerabilities. Make sure all your database security controls are enabled to ensure maximum protection.

  5. Encrypting your data and backups

    As an organization, you need to encrypt stored data and regularly backup your database. Make sure your encrypted data is stored separately from its decryption keys to protect against hackers and physical system failures.
