Cybersecurity Risk Assessment: A Step-by-Step Guide to Vulnerability Mitigation
- Hardware (servers, workstations, network devices)
- Software (operating systems, applications, databases)
- Data (customer data, financial records, intellectual property)
- Personnel (employees, contractors, vendors)
- Physical Infrastructure (data centers, offices)
Asset | Description | Value (Impact) |
|---|---|---|
Customer Database | Contains sensitive customer information | High |
Financial Server | Processes financial transactions | Critical |
Company Website | Provides information and services to customers | Medium |
Employee Laptops | Used for daily business operations | Medium |

- Malware (viruses, worms, ransomware)
- Phishing attacks (email, social media)
- Denial-of-service (DoS) attacks
- Insider threats (malicious or accidental)
- Data breaches (unauthorized access to sensitive data)
Threat | Description | Potential Impact |
|---|---|---|
Ransomware | Encrypts files and demands ransom for decryption key | Data loss, financial loss, reputational damage |
Phishing | Deceives users into revealing sensitive information | Data breach, identity theft, financial loss |
DDoS Attack | Overwhelms system with traffic, causing service disruption | Loss of productivity, revenue loss, reputational damage |
Insider Threat | Employee intentionally or unintentionally compromises security | Data breach, financial loss, legal penalties |
