Security architecture plays a vital role in securing the network infrastructure of an organization. The biggest challenge of implementing an effective security architecture is the changing threat landscape. This requires a change in mindset, as well as a repurposing of many devices.

Please review the article Enterprise Security Architecture—A Top-down Approach (Links to an external site.). Once you have reviewed the article, you will be prepared to create your original post. (NOTE: Discussion responses should be from the perspective of a system administrator.)

In your original post, answer the following:

• Discuss how the changing threat landscape affects our classic perimeter devices, such as firewalls, IDSes, and IPSes.
• How would you utilize different network security devices for the organization?
• What are the ramifications of the “encrypt everything” mindset for devices such as Network Intrusion Detection Systems?

Remember to use your textbook and other academic resources to justify your responses.
