E025: Cloud and Network Security Models

E025 is a four-unit course in WGU's Bachelor of Science, Cloud and Network Engineering (BSCNE), and it also appears in the AWS, Azure and Cisco versions of that degree. It is a security course for people who already understand networks and cloud basics.

The guidebook describes it as guiding learners through the intricacies of cloud and hybrid network security. It covers fundamental principles, emerging threats, advanced defense techniques and best practices for strengthening network security and reducing risk.

The step up from earlier courses is the move from knowing what a firewall is to designing an architecture and defending it. Students often struggle to show why each control sits where it does, rather than just listing controls.

What E025 Covers

Key Concepts Explained

Defense in Depth

No single control is enough, so layers are used: perimeter filtering, segmentation, identity controls, encryption and monitoring. If one layer fails, another limits the damage.

Shared Responsibility

In cloud environments the provider secures the underlying infrastructure while the customer secures what they configure and store. Where the line falls depends on the service type, which is why a clear answer names who is responsible for what.

Segmentation and Least Privilege

Segmentation places systems into zones with controlled traffic between them. Least privilege gives each user and service only the access needed.

Typical Assignments and How to Approach Them

Check your task for the exact format. Work in this course typically asks you to describe, justify or build a secure design.

Threat-to-Control Mapping

A table that maps threats to controls is the quickest way to show reasoning. List the main threats to the network in your scenario, then the control that addresses each, the layer where it operates and the framework principle it reflects.

A Study Approach for Each Competency

For the framework competency, pick one or two well-known security frameworks and learn what each is for. Be ready to explain how a framework influences a real design choice, such as where to segment a network or how to manage identities. A framework is a tool for decisions, not a list to recite.

For the principles competency, prepare a plain-language explanation and a quick example of each major principle: defense in depth, least privilege, segmentation, encryption and monitoring.

For the implementation competency, practice sketching a hybrid architecture and then annotating it, marking where traffic is filtered, where it is encrypted and where it is logged. Finally, test your own design by tracing an attacker's path through it and noting where it would be stopped.

Where Students Get Stuck

• Control lists with no reasons. Each control needs a threat it answers.
• Blurry responsibility. Be clear about what the provider handles and what you handle.
• Ignoring the hybrid link. The connection between the data center and the cloud is a prime place for weaknesses.
• Frameworks mentioned but not used. Show how a framework shaped a design decision.

Study Tips for E025

• Sketch a network diagram first, then add controls one layer at a time.
• Keep a short glossary of terms so your wording is precise.
• Test your design by imagining an attacker's route and checking where it would be stopped.
• Check rubric lines against your headings before submitting.

How We Help with E025

Send the task, any diagrams and the rubric. A writer with network and security experience can prepare a model explanation, walk through the reasoning behind an architecture, or review your draft. This is study support only: we do not access lab environments, and you complete your own work under WGU's academic integrity policy.
