Internet Networks & Network Security | Google Cybersecurity Certificate

Published 2023-05-08
This is the third course in the Google Cybersecurity Certificate. In this course, you will explore how networks connect multiple devices and allow them to communicate. You'll start with the fundamentals of modern networking operations and protocols. For example, you'll learn about the Transmission Control Protocol / Internet Protocol (TCP/IP) model and how network hardware, like routers and modems, allow your computer to send and receive information on the Internet. Then, you'll learn about network security. Organizations often store and send valuable information on their networks, so networks are common targets of cyber attacks. By the end of this course, you'll be able to recognize network-level vulnerabilities, and explain how to secure a network using firewalls, system hardening, and virtual private networks.

    Just completed my Google IT support professional certificate as a way to get my foot into the door of IT. I’m in healthcare so transitioning is no joke lol. Now just started the new Google cyber security program. Cyber security engineer is my end goal. Let’s go!
  • I learned networking in 2002. It has changed so much since then. I’m so glad I’m having the opportunity to return to the IT industry. I greatly appreciate your free course, which cost me thousands 20 years ago and was not as well designed as yours. A million thanks.

  • @user-su1lm3qr8f
    My passion to be in the I.T space nearly got quenched until I met this google training package, I am inspired each an everyday to learn and listen more. I cant wait to give back what I have learnt as an It T analyst or cyber security analyst. Its a great journey. Thanks everyone and especially to the google team
  • Many Many Thanks. Regular Upload Will Be A Great Help To Keep Connected.

    I am still a baby in Cybersecurity. It's a great pleasure to have access to this opportunity. Many thanks to Google. Hopefully, I will also be able to become Guru in it soon too.
  • It is worth it. I just completed the Google Cybersecurity Professional Certificate today 5th June 2023. Although, I spend an average of 12 hours every day for 30 days. I enrolled on 05th May 2023. I started the program without any background order python basic, both today, I can use Linux, Suricata, SQL, Python, and Splunk tools. It helped me to develop security mindset. I am really happy. Mind YOU, IT ALSO GIVES 30% discount for CompTIA certification. Next two weeks will be preparation for interviews and elevation pitch is next. I am sure I will be in the first 10 CANDIDATES to complete it today. That is if there is people are also crazy marathon learners like me. I penned down every word from the videos, made note from the reading and worked all the lab activities. My notebook is about 600 PAGES. I just wanted it to sink into my brain and i call recall them unconsciously. It was a great moment for me especially someone who is new to cybersecurity. During this month, i spent 318 hours learning cybersecurity, checking your reference resources and caught extra bit completion certificate from Cyberprotect and DoD unclassified training. It is time to go and complete my IT SUPPORT Professional Certificate that I stopped at course 2 to enable me complete Google Cybersecurity Professional Certificate. I can assure that your life will change if you take the courses lie your life depend on it. Use the extra suggestion resources. The more you expose yourself to cybersecurity resources the more it becomes easier for you. Increase exposure to those materials is more like you are training your brain repeatedly. It is difficult, especially, if one is new to tech. But it is doable
  • Hats off to you. I thoroughly enjoyed and appreciate your presentation.
  • Sir, you truly disserve a million thanks for such good narration about the network fundamentals. even i have hiatus back to IT after a decade and finding it so easy after listening to you. If it happens to perceive same course those days it was so expensive. wishing many more articles like this related to CyberSecurity. May God Bless You and Your associates.
