Securing your Linux server on the network and understanding network routing is a great skill to have. This course will teach you how to secure your system with a firewall and configure networking and network address translation (NAT).

Protecting your servers from the internet and obscuring your client systems from the internet are huge cyber security mitigations. In this course, LFCS Additional Networking Topics, you’ll learn to implement network security mitigations. First, you’ll explore raw packet filtering techniques. Next, you’ll discover how scripted applications like firewalld and UFW can simplify the firewall management. Finally, you’ll learn how to combine raw packet filtering into your simplified management to ensure all aspects are available. When you’re finished with this course, you’ll have the skills and knowledge of Linux networking needed to secure network access.

Reviews summary

Practical linux networking and security

According to learners, this course offers a solid foundation in Linux networking and security mitigations, making it highly relevant for those pursuing the LFCS certification or needing practical network administration skills. Students particularly appreciate the hands-on approach through topics like IPtables, UFW, Firewalld, and NAT, noting the clear explanations of complex concepts. While largely considered effective for skill development, some learners suggest the pace can be challenging for absolute beginners or desire deeper dives into advanced troubleshooting. Overall, it's a valuable resource for enhancing Linux system administration capabilities.
Directly supports Linux Foundation Certified System Administrator.
