Cybersecurity has become an essential part of modern business operations because organizations depend heavily on computers, networks, cloud platforms, databases, applications, and digital communication. As the amount of digital information increases, organizations also face a growing number of cybersecurity risks.
A Cybersecurity Risk Assessment helps an organization identify potential threats, understand vulnerabilities, estimate the possible impact of security incidents, and decide which security controls should be implemented first.
A case study approach makes this topic easier to understand because students can examine a realistic organization and apply cybersecurity risk assessment concepts to an actual business situation.
This assignment presents a hypothetical case study of a medium sized e commerce company called NovaCart. The organization stores customer information, processes online orders, uses cloud services, operates an internal employee network, and depends on third party payment services.
The case study examines the organization's assets, threats, vulnerabilities, risks, risk levels, security controls, mitigation strategies, incident response process, and future improvements.
The objective is not only to identify cybersecurity problems but also to demonstrate how an organization can systematically manage those risks.
What Is Cybersecurity Risk Assessment
Cybersecurity risk assessment is the process of identifying information security risks and evaluating their potential effect on an organization's systems, data, users, and operations.
A basic risk assessment involves:
- Identifying important assets
- Identifying potential threats
- Identifying vulnerabilities
- Estimating likelihood
- Estimating impact
- Calculating or categorizing risk
- Selecting appropriate controls
- Monitoring the remaining risk
A simplified relationship can be represented as:
Threat + Vulnerability + Impact
↓
Security Risk
↓
Risk Treatment
↓
Continuous Monitoring
The purpose is not necessarily to eliminate every possible risk. Instead, organizations generally aim to understand and reduce risks to an acceptable level.
Difference Between Threat, Vulnerability, and Risk
These three terms are often confused.
Threat
A threat is something that could potentially cause harm.
Examples include:
- Phishing
- Malware
- Ransomware
- Insider misuse
- Credential theft
- Hardware failure
- Natural disasters
Vulnerability
A vulnerability is a weakness that could be exploited or could contribute to an incident.
Examples include:
- Unpatched software
- Weak authentication
- Excessive user privileges
- Poor security configuration
- Missing backups
- Inadequate employee training
Risk
Risk represents the potential for a threat to take advantage of a vulnerability and cause an unwanted outcome.
For example:

Risk Score = Likelihood × Impact
Each factor can be rated from 1 to 5.
| Score | Meaning |
|---|---|
| 1 | Very Low |
| 2 | Low |
| 3 | Moderate |
| 4 | High |
| 5 | Very High |
The resulting score can then be categorized for prioritization.
Risk Matrix
A simplified risk matrix can be used.
| Likelihood | Impact | Risk Level |
|---|---|---|
| Low | Low | Low |
| Low | High | Moderate |
| Moderate | Moderate | Moderate |
| High | High | High |
| Very High | Very High | Critical |
The exact thresholds should be defined by the organization's risk management policy.
Cybersecurity Risk Register
The assessment produces the following hypothetical risk register.
| Risk | Likelihood | Impact | Priority |
|---|---|---|---|
| Phishing attack | High | High | High |
| Ransomware | Moderate | Very High | High |
| Credential compromise | High | High | High |
| Web application vulnerability | Moderate | Very High | High |
| Cloud misconfiguration | Moderate | High | High |
| Insider misuse | Low | High | Moderate |
| Lost employee device | Moderate | Moderate | Moderate |

Treating Every Risk Equally
Risk assessment exists partly to prioritize security efforts.
Focusing Only on Technology
People and processes are also important components of cybersecurity.
Forgetting Third Party Risks
Modern organizations often depend on external services.
Ignoring Residual Risk
Security controls reduce risk but rarely eliminate it completely.
Using Unsupported Risk Scores
A risk score should have a clearly explained methodology.
Advantages of Cybersecurity Risk Assessment
A structured assessment provides several benefits.
- Identifies important security weaknesses
- Helps prioritize security investments
- Improves organizational awareness
- Supports incident preparedness
