What is a key requirement regarding default system passwords according to security standards?

A key requirement regarding default system passwords according to security standards is to avoid using vendor-supplied defaults for system passwords. Security best practices emphasize that default passwords, which are often well-known and publicly available, can create significant vulnerabilities in systems. Attackers frequently utilize these default credentials to gain unauthorized access to systems, making it essential for organizations to change them to strong, unique passwords immediately upon system configuration.

By changing the default passwords, organizations reduce the risk of unauthorized access and bolster their overall security posture. This practice is particularly vital as many security incidents stem from the failure to change these default settings. Ensuring that all systems have unique and secure passwords is a fundamental aspect of maintaining a secure environment, leading to the conclusion that avoiding vendor-supplied defaults directly contributes to greater overall security.
