Frequently Asked Questions
What is device hardening?
Device hardening is securing a system by removing unneeded services, changing defaults and applying secure settings. It shrinks the attack surface and makes compromise harder.
What are CIS Benchmarks?
CIS Benchmarks are consensus-based configuration guides for securing operating systems, network devices and applications. Teams use them as baselines and audit checklists.
What are common hardening steps for network devices?
Disable unused services and ports, use strong authentication, restrict management access, keep firmware updated and log changes. This free Codelivly room covers these in practice.
