IT-FPX4803 is an overview of information assurance and security for network administrators who must protect an organization from exposure to the Internet, and for network designers who build security into their designs.
Capella says students identify and apply strategies against hackers and malicious software, use firewalls and gateways, and build authentication and encryption skills.
Students also identify methods for attacking a network and validate defenses against them. Capella states that on successful completion students are prepared to take the CompTIA Security+ exam, and that parts of the course draw on the Google IT Support professional certificate material delivered through Coursera in the courseroom at no extra cost.

| Attack and validation | Methods used to attack a network and how to test defenses |
Key Concepts Explained
Defense in Depth
No single control is enough. Layers such as a firewall, authentication, encryption, patching and monitoring mean that one failure does not expose everything.
Illustration (invented): A company website is attacked through a stolen password. The firewall allows the traffic because it looks legitimate, but multi-factor authentication stops the login. This shows why identity controls complement network controls.
Symmetric and Asymmetric Encryption
Symmetric encryption uses one shared key and is fast, so it protects bulk data. Asymmetric encryption uses a public and private key pair, which solves the problem of sharing keys; in practice, secure connections use asymmetric methods to agree a symmetric key.
Authentication Factors
Factors are something you know, have or are. Combining two or more is multi-factor authentication and is much harder to defeat than a password alone.
Typical Assignments and How to Approach Them
The catalog lists no specific assessments, so this is a general guide.
| Work type | What it tests | How to approach it |
|---|---|---|
| Threat analysis | Recognizing attack methods | Describe the attack path, then the control that breaks it |
| Security design | Applying defenses | Layer controls and justify each one |
| Firewall or access rules | Configuration logic | Default deny, then allow only what is needed |
| Defense validation | Testing | Explain how you would confirm the control works |
Studying for the Assessments and Security+
The course and the certification overlap but they are not the same. Use the course assessments to apply ideas, and the exam objectives to check coverage.
- Collect the scoring guide criteria for the assessment in front of you.
- Work through the related Coursera material provided in the courseroom.
- Summarize each topic on one page in your own words.
- Test yourself with scenario questions rather than definitions alone.
- If you plan to take Security+, read CompTIA's published objectives and mark gaps.
Matching Attacks to Defenses
A table of attack, effect and defense is one of the best revision tools for this course.
| Threat | What happens | Defense |
|---|---|---|
| Phishing | User tricked into giving credentials | Training, multi-factor authentication |
| Malware | Harmful software runs on a device | Endpoint protection, patching, least privilege |
| Denial of service | Service overwhelmed with traffic | Rate limiting, filtering, capacity planning |
| Eavesdropping | Traffic read in transit | Encryption of data in transit |
Add a column for how you would validate each defense, since the course description includes validating defenses against attack methods.
Self-Check Questions
| Question | Short answer |
|---|---|
| Authentication or authorization? | Authentication proves who you are; authorization decides what you may do |
| What does a firewall rule base usually start from? | Deny by default, then allow what is needed |
| Hashing or encryption for stored passwords? | Hashing, ideally salted |
| What is defense in depth? | Layered controls so one failure is not fatal |
| How could you validate a defense? | Test it against the attack it is meant to stop |
Worked Walkthrough: Securing a Small Office Network
Imagine a scenario describing a small office with a router, a few computers, a file server and Wi-Fi. A strong answer proceeds in layers.
Perimeter: a firewall that denies inbound traffic by default and allows only what is needed. Network: separate guest Wi-Fi from internal systems.
Identity: strong, unique passwords with multi-factor authentication for remote access. Data: encrypt laptops and backups. Hosts: apply updates and run protection software. People: short, regular awareness training about phishing.
Then explain how you would validate the design, for example by testing that the guest network cannot reach the file server. The scenario is invented, but the pattern of risk, control and test is what scoring guides typically look for.
Where Students Get Stuck
- Listing tools without reasoning. Say what risk each control addresses.
- Confusing similar terms. Keep clear on authentication versus authorization and hashing versus encryption.
- Attacker-only thinking. The course also asks you to validate defenses.
- Treating Security+ as the goal. The course tests applied understanding in its own assessments.
Study Tips
- Make a table of attack types, how each works and the matching defense.
- Use the Coursera material in the courseroom alongside the assessments.
- Practice explaining a concept in two sentences without jargon.
- Check the official CompTIA objectives if you plan to sit Security+.
