Linux Networking and Identity Management

A Linux system in isolation has no enterprise value. This course teaches you how to connect your systems to real networks — and how to control who can access them and what they can do. You'll start with local identity management: creating and modifying user accounts and groups, configuring system-wide environment profiles, setting user resource limits, managing delegated privileges, and integrating Linux systems with LDAP-based enterprise directories. From there, the focus shifts to networking. You'll configure IPv4 and IPv6 addressing, set up hostname and DNS resolution, and verify the status of network services in production environments. The course then builds into advanced configurations: bridge and bonding devices for redundancy, packet filtering with firewall rules, port redirection, and network address translation. The final module covers the high-availability and security patterns that enterprise administrators rely on: reverse proxies, load balancers, time synchronization, and SSH server and client configuration. Every topic is supported by hands-on labs that place you in realistic network engineering scenarios. Who this is for: IT professionals, network engineers, and DevOps administrators with foundational Linux CLI skills who are ready to manage networked, multi-user Linux environments at an enterprise level.
