What do you do if you want to learn about network security online?

To learn about network security online, start by identifying learning resources such as online courses, tutorials, videos, and articles on platforms like Coursera, Udemy, and Cybrary. Engage with online communities dedicated to network security, participate in virtual labs, follow blogs and podcasts, attend webinars and conferences, and practice with Capture the Flag (CTF) challenges. Consider obtaining recognized certifications like CompTIA Security+ or Certified Ethical Hacker (CEH) to validate your skills. By actively engaging with these online resources, you can effectively develop your knowledge and skills in network security.

For anyone entering the cybersecurity field, I always recommend starting with the fundamentals. Start with the basics of network security by understanding the basics of encryption, network protocols, firewalls, and intrusion detection. There are several courses and training on online platforms specific to network security, such as those offered by Cybrary, Udemy, Coursera and edX. Purchase courses that cover topics such as network security, pen testing, and vulnerability analysis ??

From my experience, online courses offer a structured path to dive deep into network security. Free resources, like forums and blogs, provide up-to-date insights. E-books and papers offer in-depth knowledge. Video tutorials and simulation tools provide practical learning. Certification prep solidifies skills. Establishing a home lab and networking with professionals add real-world experience. It's all about combining these resources for

Internet give us a great opportunity of learning without border. You may attend online courses which are free and paid and they give you good way to get started.

Initiating knowledge through concepts and fundamentals is the best practice for learning about a given topic. It is not possible to understand how network and security products work, for example, if we do not have the concepts of how network connectivity occurs, or how an attack is disseminated from the OS understanding to the connectivity carried out.

The search for free resources has increased a lot, but also with technology advancing, many blogs, communities and groups share information daily about trends in the security market, as well as basic concepts and preparatory studies for professional development in the area. We must consume free resources to complement our study action plans.

The appropriate type of learning depends largely on the person's profile. Videos, books, or other types of studies are important. Regardless, I understand that the priority is the use of simulation tools to ensure that hands-on work is carried out and that we have confidence when putting our concepts into practice.

There are many virtual laboratories to learn and not need to use your company's infrastructure (??). Set up virtual labs at home using software like VirtualBox or VMware to practice configuring firewalls, intrusion detection, and other security techniques in a controlled environment. Here you can do whatever you want safely. Also learn through case studies and real incidents. Post-incident is a great way to understand failures in depth and how to fix them. Analyze case studies of network security incidents to understand the techniques used by attackers and learn from other organizations' security failures.

To enhance your technical expertise, consider establishing a home lab utilizing virtualization software such as VirtualBox or VMware. Engage in practical exercises involving firewall configuration, VPN setup, and the implementation of robust security measures. Additionally, explore cloud resources offered by Microsoft Azure, AWS, and Google for constructing lab environments. Some platforms even provide complimentary trial licenses for testing and research purposes. Capitalize on these opportunities to gain hands-on experience and deepen your understanding of technical concepts..

It is easy to get overwhelmed by the amount of resources available on internet. Being practical in your learning journey will help you progress quickly. Simple projects like building a small home lab (even with only one laptop and one router) or interconnecting docker containers (opening services on different ports) are a practical way to start for beginners.
