What is networking in cyber security?
Networking in cybersecurity involves protecting the infrastructure, data, and devices that are connected through networks. This encompasses various practices, technologies, and strategies to ensure the confidentiality, integrity, and availability of information transmitted across or stored in network systems. Key aspects include:
Network Security Protocols: Protocols like SSL/TLS for secure data transmission, VPNs for secure remote access, and IPsec for securing IP communications.
Firewalls: Hardware or software solutions that monitor and control incoming and outgoing network traffic based on predetermined security rules, acting as a barrier between trusted and untrusted networks.
Intrusion Detection and Prevention Systems (IDPS): Systems that monitor network traffic for suspicious activities and known threats, and can take actions to prevent breaches.
Encryption: Techniques to protect data confidentiality by encoding information so that only authorized parties can access it, commonly used in securing data in transit and at rest.
Access Control: Mechanisms to ensure that only authorized users and devices can access network resources, often involving authentication and authorization processes.

Network Segmentation: Dividing a network into multiple segments or subnets to enhance security and improve performance by isolating sensitive data and limiting access.
Endpoint Security: Protecting devices that connect to the network, such as computers, smartphones, and IoT devices, through antivirus software, anti-malware tools, and regular patching.
Security Information and Event Management (SIEM): Tools that provide real-time analysis of security alerts generated by network hardware and applications, aiding in the detection of and response to threats.

Incident Response: Procedures and processes for detecting, investigating, and responding to network security incidents to mitigate damage and recover from attacks.
Network Monitoring and Analysis: Continuous monitoring of network traffic for abnormal patterns or behaviors that may indicate a security threat, using tools and techniques like packet sniffing and flow analysis.
Compliance and Auditing: Ensuring that network security practices comply with relevant laws, regulations, and standards, and conducting regular audits to assess and improve security posture.
Effective networking in cybersecurity requires a combination of technical measures, policies, and practices designed to protect against threats, ensure data integrity, and maintain the availability of network resources.
Can a non-IT person learn cyber security?
Yes, a non-IT person can learn cybersecurity. While having a background in IT can be beneficial, it is not a strict prerequisite for entering the field of cybersecurity. Many successful cybersecurity professionals have come from non-IT backgrounds and have leveraged various resources and learning pathways to gain the necessary skills and knowledge.
Here’s how a non-IT person can learn cybersecurity:
Steps to Learn Cybersecurity:
Understand the Basics:
Beginner Courses: Start with introductory courses that cover the basics of computers, networking, and cybersecurity concepts. Websites like Coursera, edX, and Udemy offer beginner-friendly courses.
Books and Online Resources: Read books such as "Cybersecurity for Beginners" by Raef Meeuwisse or "Hacking: The Art of Exploitation" by Jon Erickson. Websites like Cybrary and SANS Institute provide valuable resources.
Get Hands-On Experience:
Labs and Simulations: Use platforms like Cyber Aces, Hack The Box, and TryHackMe, which offer hands-on labs and exercises to practice cybersecurity skills in a controlled environment.
Home Lab Setup: Set up a home lab using virtual machines (VMs) to practice configuring systems, running security tools, and simulating attacks and defenses.
Certifications:
Entry-Level Certifications: Consider pursuing entry-level certifications such as CompTIA Security+, which covers fundamental cybersecurity principles and is designed for beginners.
Further Certifications: As you progress, you can aim for more advanced certifications like Certified Ethical Hacker (CEH), Certified Information Systems Security Professional (CISSP), or Offensive Security Certified Professional (OSCP).
Join Communities and Networks:
Online Communities: Join cybersecurity forums and online communities such as Reddit’s r/cybersecurity, and participate in discussions to learn from others and stay updated on industry trends.
Local Groups and Meetups: Participate in local cybersecurity meetups and groups to network with professionals and learn from their experiences.
Formal Education:
Degree Programs: If you prefer a structured learning path, consider enrolling in a cybersecurity degree or certificate program at a university or community college.
Bootcamps: Intensive bootcamps, such as those offered by SANS, Flatiron School, or Cyber Bootcamp, provide immersive training programs designed to quickly build your cybersecurity skills.
Stay Current:
News and Blogs: Follow cybersecurity news, blogs, and podcasts to stay informed about the latest threats, technologies, and best practices. Examples include Krebs on Security, Dark Reading, and the CyberWire podcast.
Continuous Learning: Cybersecurity is a constantly evolving field. Engage in continuous learning through online courses, webinars, and industry conferences.
