1 Read blogs and newsletters

Keeping up with the latest trends and developments in network security can be made easy and accessible through reading blogs and newsletters from reputable sources. These sources can provide valuable insights, tips, tricks, and case studies from experts and practitioners in the field. Network engineers can also learn from the experiences and challenges of others and discover new tools and techniques to improve their network security. Some examples of blogs and newsletters to follow are Cisco Security Blog, Network Security Podcast, and Network Computing Security Newsletter. The former covers topics such as threat intelligence, firewall, VPN, cloud security; the latter is a weekly podcast featuring interviews with network security professionals, researchers, and vendors; while the last is a monthly newsletter that delivers news, analysis, and advice on network security issues such as ransomware, zero trust, encryption, etc.

2 Take online courses and certifications

If you want to further your network security knowledge, taking online courses and certifications is a great way to learn new skills, refresh existing ones, or validate your expertise. You can get a structured and comprehensive understanding of network security concepts, principles, and practices, as well as test your knowledge and skills. Additionally, you can choose courses and certifications that match your level, goals, and interests. For example, CompTIA Network+ is vendor-neutral certification that covers topics such as firewalls, encryption, access control, etc. Cisco Certified Network Associate (CCNA) Security is a vendor-specific certification that focuses on securing Cisco networks. Coursera Network Security Specialization offers online courses on cryptography, authentication, network attacks, etc., plus a certificate of completion after the courses and capstone project are completed.

Cisco and other vendors offer a variety of courses that really helps understanding more security concepts and give you the capability of implementing these concepts into his network. Network engineers can easily learn security and get into this field and even has advantage over a starter. Network security is more like securing your network and since you already understand your network well, studying by courses and certifications will help you securing your network professionally.

To enhance their knowledge in network security, network engineers should consider pursuing relevant certifications and engaging in online courses. Certifications like Juniper's JNCIA-Sec, CompTIA Security+, and CISSP offer structured learning paths and are highly regarded in the industry. Online platforms such as Coursera, Udemy, and Cybrary provide courses covering various aspects of network security, from basic principles to advanced tactics. My personal favorite is O'Reilly's learning site. These courses, often created by industry experts, offer practical, hands-on learning experiences. Additionally, engaging in certification tracks not only boosts knowledge but also enhances professional credibility and marketability.

3 Join online communities and forums

Gaining a deeper understanding of network security can be advanced by joining online communities and forums. Here, you can interact with other network engineers, ask questions, share ideas, and get feedback. Additionally, you can learn from your peers, exchange opinions, and solve problems. You may also find opportunities to network, collaborate, and mentor or be mentored by other network engineers. Examples of online communities and forums include Reddit r/networking, Stack Overflow Network Engineering, and Network Engineering Slack. Reddit r/networking is a subreddit where you can discuss anything related to networking and network security topics such as firewall rules, VPN configuration, threat detection, and more. Stack Overflow Network Engineering is a Q&A site where you can ask and answer questions related to network engineering and security topics such as encryption protocols, network segmentation, security policies, and more. Finally, Network Engineering Slack is a Slack group where you can chat with other network engineers and join channels related to network security topics such as malware analysis, penetration testing, security tools, and more.

4 Practice on labs and simulations

A fourth way to improve your network security knowledge is to practice on labs and simulations that can provide a hands-on and experiential way to learn. You can use these to experiment with different security configurations, techniques, and tools, and learn from mistakes. Examples of labs and simulations you can practice on include Cisco Packet Tracer, Hack The Box, and NetLab+. These offer various challenges that test your network security skills, such as penetration testing, vulnerability scanning, encryption, and more. Additionally, they allow you to create, configure, and troubleshoot virtual networks with topics such as firewall, VPN, access control, and more.

5 Attend webinars and events

One way to boost your network security knowledge is to attend webinars and events. By doing so, you can hear from industry leaders and researchers, ask questions, and participate in discussions. You can also use these opportunities to expand your network, find mentors or mentees, and discover new opportunities. Examples of webinars and events include SANS Webcasts, Cisco Live, and Black Hat. SANS Webcasts provide insight into topics such as threat hunting, incident response, malware analysis, and more. Cisco Live is a global event that features sessions on Cisco products and solutions for network security. Black Hat is a premier event that showcases the latest research in network security, as well as offers trainings, briefings, and networking sessions.
