What security best practices should be followed for installation?

Employing least privilege and utilizing SSL certificates are essential security best practices during installation. The principle of least privilege ensures that any user or application has only the necessary access rights to perform their functions and nothing more. This minimizes the risk of unauthorized access and potential damage to the system.

SSL certificates are crucial for establishing encrypted communications between clients and servers, which protects sensitive data during transmission. This is particularly important in environments where data security and privacy are paramount. The use of SSL helps safeguard against eavesdropping and man-in-the-middle attacks.

In contrast, using public IP addresses, avoiding network segmentation, and relying on default configurations can introduce significant security vulnerabilities. Public IP addresses can expose systems directly to the internet, increasing the risk of attacks. Lack of network segmentation can make it easier for attackers to move laterally within a network if they gain access to one area. Additionally, default configurations often come with known vulnerabilities that can be exploited if not properly secured and customized for specific environments. By focusing on least privilege and implementing SSL certificates, a more robust security posture can be achieved.
