Network Security

The Google Network Security Certificate provides learners with foundational knowledge of how computer networks operate and how to protect them from modern cyber threats. Designed for beginners, this Specialization introduces core networking concepts alongside practical security techniques used by cybersecurity professionals.

Guided by Google experts, learners gain hands-on experience analyzing network traffic, monitoring logs, and securing both traditional and cloud-based networks using industry tools such as Wireshark, tcpdump, Splunk, and Google SecOps. By the end of the program, learners will be able to identify vulnerabilities, investigate suspicious activity, and apply defensive strategies to protect network environments.

Estimated Time to Complete
