Explain how the network security would be improved in each case below: 1. Avoiding single points of failure (SPoF). 2. Using IPv6. 3. Designing a segmented network. 4. Using an IDS for unfiltered traffic. 5. Encrypting protocols (control) in addition to data. 6. Using VPNs for remote access. 7. Embracing the zero trust approach. Explain the risks of each situation below and how would you mitigate them: 8. Switches not supporting VLANs. 9. Static IP addresses. 10. Single factor authentication (SFA). 11. Exposing Remote Desktop Protocol (RDP) to the public. 12. Placing servers with public services, such as a web server, on the Intranet..
