5 Cisco Device Security Settings YOU NEED NOW

In 2023, thousands of Cisco IOS-XE devices were compromised due to BASIC configuration weaknesses. Many of those devices were running default services and unsecured management settings that could have been prevented if they followed these tips. In this video, I walk you through 5 essential Cisco device security configurations based on Cisco’s official IOS-XE Hardening Guide, DISA STIG recommendations, and industry best practices. We cover: • Securing the management plane (SSH and access-class) • Disabling unnecessary services • AAA authentication and local fallback • Brute-force protection and login controls • Credential hardening If you manage Cisco routers or switches, are a network engineer/admin (or want to be one), studying for the Cisco CCNA/CCNP, then these are foundational configurations you should know about and have enabled.
