Episode 156: Hardening Network Devices — Interfaces, Passwords, and Firmware Management

Securing the network starts with securing its devices. In this episode, we focus on hardening best practices for routers, switches, and firewalls. This includes disabling unused interfaces, enforcing strong password policies, and limiting access with ACLs and administrative timeouts. We also explore remote access security—ensuring SSH replaces Telnet, enabling HTTPS instead of HTTP, and monitoring logins for anomalies.Firmware and software vulnerabilities are common attack vectors, so we also discuss version control, patch scheduling, and rollback planning. You’ll learn how to establish a secure configuration baseline and maintain it through automated compliance checks. This episode is essential for keeping infrastructure components secure and aligned with organizational policies.
