Domain 4: Communication and Network Security
4.1 Assess and implement secure design principles in network architectures:
- Open System Interconnection (OSI) and Transmission Control Protocol/Internet Protocol (TCP/IP) models
- Internet Protocol (IP) networking (for example, Internet Protocol Security (IPSec) or Internet Protocol (IP) v4/6)
- Secure protocols
- Implications of multilayer protocols
- Converged protocols (for example, Fiber Channel Over Ethernet (FCoE), Internet Small Computer Systems Interface (iSCSI), and Voice over Internet Protocol (VoIP))
- Micro-segmentation (for example, Software Defined Networks (SDN), Virtual eXtensible Local Area Network (VXLAN), encapsulation, and Software-Defined Wide Area Network (SD-WAN))
- Wireless networks (for example, Li-Fi, Wi-Fi, Zigbee, and satellite)
- Cellular networks (for example, 4G, and 5G)
- Content Distribution Networks (CDN)
4.2 Secure network components:
- Operation of hardware (for example...
