Network Security Fundamentals
Deep dive into OSI & TCP/IP models, common protocols and their vulnerabilities, network segmentation strategies, and packet analysis fundamentals.
Master network security fundamentals, perimeter defense technologies, cloud security architecture, and the Zero Trust model that's revolutionizing enterprise security.
By the end of this module, you will be able to:
Explain the OSI and TCP/IP models and identify security vulnerabilities at each layer
Configure and manage firewalls, IDS/IPS systems, and VPN technologies
Implement cloud security controls across IaaS, PaaS, and SaaS environments
Design and deploy Zero Trust Architecture following NIST SP 800-207 guidelines
Deep dive into OSI & TCP/IP models, common protocols and their vulnerabilities, network segmentation strategies, and packet analysis fundamentals.
Firewalls (stateful vs. stateless, NGFW), IDS/IPS technologies, VPN implementations, NAC solutions, and defense-in-depth strategies.
Cloud service models (IaaS, PaaS, SaaS), shared responsibility model, cloud-specific threats, CASB, and securing AWS/Azure/GCP environments.
Zero Trust principles, NIST SP 800-207 framework, micro-segmentation, identity-centric security, and implementing ZTA in enterprises.
Test your knowledge of network security, cloud security, and Zero Trust concepts. 20 questions, 70% required to pass and unlock Module 3.
Multiple layers of security controlsβlike the seven walls of Constantinople that held for 1,000 years. If one layer fails, others still protect.
In cloud computing, security is a partnership. The provider secures the cloud; you secure what's IN the cloud. Misunderstanding this caused the 2019 Capital One breach.
"Never trust, always verify." Inspired by Google's BeyondCorp after the 2009 Operation Aurora attack. Trust nothing, verify everything, assume breach.
Users get only the minimum permissions needed. As Confucius might say: "Give a person the keys they need, not the keys they want."
A former AWS employee exploited a misconfigured Web Application Firewall (WAF) to access 100 million customer records. This module teaches you exactly what went wrong and how proper cloud security controls could have prevented it.
