Device Placement

• Proper placement of routers, switches, and access points is crucial
• Correct placement helps in:
  • Optimal data flow
  • Minimizing latency
  • Enhancing security
• Routers at the network’s edge help filter traffic efficiently
• Strategic placement of access points ensures coverage and reduces interference
• Switches should be located for easy connection to network segments

Security Zones and Screened Subnets

• Security Zones — Isolate devices with similar security requirements
• Screened Subnets
  • Act as buffer zones between internal and external networks
  • Hosts public-facing services, protecting core internal networks
  • Use the term “screened subnet” instead of “DMZ” for modern configurations

Attack Surface

• Refers to points where unauthorized access or data extraction can occur
• A larger attack surface increases the risk of vulnerabilities
• Identify and mitigate vulnerabilities to reduce the attack surface
• Regularly assess and minimize the attack surface for network security

Connectivity Methods

• Choose connectivity methods that influence network performance, reliability, and security
• Wired (e.g., Ethernet) offers stability and speed but restricts mobility
• Wireless (e.g., Wi-Fi) provides flexibility but may suffer from interference and security issues
• Consider factors like scalability, speed, security, and budget constraints when choosing connectivity methods
