Information Security Fundamentals Training
Overview
This course provides a clear and practical introduction to the essentials of information security.
It covers core concepts like authentication methods, access controls, common network attacks (DoS, spoofing, malware), infrastructure defenses (firewalls, IDS, VPNs), wireless security, web server protection (IIS 7), IPSec configuration, and Public Key Infrastructure (PKI) basics — all explained in simple steps with real-world examples.
Perfect for beginners, IT support professionals, or anyone starting in cybersecurity who wants to understand threats, defenses, and key technologies used to protect networks, servers, and data.
Key Features
🌐 Easy-to-follow basics of information security, authentication, and access control
🔒 Covers real threats: DoS/DDoS, spoofing, malware types (viruses, worms, trojans, rootkits), phishing, SQL injection
🛡️ Infrastructure protection: Firewalls, IDS/IPS, honeypots, VPNs, DMZ, wireless security (WEP/WPA)
⚡ Hands-on focus: IIS 7 installation & securing, IPSec policies in Windows 2003, basic PKI setup (CA hierarchy, certificates)
📡 Explains symmetric/asymmetric encryption, digital certificates, and certificate authorities
😊 Beginner-friendly – uses simple explanations, no heavy technical background needed at start
🚀 Builds strong foundation for further certifications like CompTIA Security+, CEH basics, or entry-level security roles
