Explanation

Regularly updating firmware on network devices patches known security vulnerabilities and keeps devices protected against newly discovered exploits. Using default credentials (D) is a critical security failure, as attackers routinely scan for devices with factory-default usernames and passwords. Disabling logging and monitoring (A) removes visibility into suspicious activity, making it harder to detect attacks. Firmware updates are a foundational hardening step for routers, switches, firewalls, and other network equipment.
