Description
🔐 Network Security Training: Detailed Overview
🎯 Purpose of Network Security Training
Network security training equips individuals with the skills and knowledge needed to design, implement, monitor, and defend secure networks. It addresses threats such as unauthorized access, data breaches, DDoS attacks, malware, and insider threats by focusing on protocols, architectures, tools, and best practices.
🧠 Learning Objectives
By the end of network security training, participants should be able to:
- Understand fundamental networking and security concepts.
- Identify and respond to network-based threats and vulnerabilities.
- Configure firewalls, intrusion detection/prevention systems (IDS/IPS), and VPNs.
- Secure wireless and wired networks.
- Perform network traffic analysis and incident response.
- Implement network segmentation, access controls, and encryption.
