IT 286: Network Security Concepts

Investigates technologies and practices used to protect enterprise communication networks. Covers firewall architectures, intrusion detection/prevention systems (IDS/IPS), Virtual Private Networks (VPNs), cryptographic protocols (TLS/IPsec), wireless security standards, and network access control models.

• Network boundary defenses: stateful inspection firewalls, next-generation firewalls (NGFW), and DMZ design in IT 286
• Intrusion Detection and Prevention Systems (IDS/IPS): signature vs anomaly-based detection rules in Network Security Concepts
• Virtual Private Networks (VPN): IPsec tunnel/transport modes, IKE phases, and SSL/TLS VPN protocols for IT 286
• Cryptographic protocols and PKI: symmetric/asymmetric encryption, digital signatures, and certificate authorities at Purdue Global
