Risk Assessment Process

⋮

 Risk assessment is a systematic process used to identify, analyze, and evaluate security risks within an organization. The goal is to understand potential threats, vulnerabilities, and their impact to implement effective mitigation strategies.


1. Identify Assets

  • Determine critical assets such as hardware, software, networks, data, and personnel.
  • Prioritize based on business importance and sensitivity.

🔹 Example: Customer databases, cloud services, financial records, employee credentials.


2. Identify Threats

  • Recognize potential threats that could exploit vulnerabilities.
  • Common threats include malware, hackers, phishing, insider threats, and natural disasters.

🔹 Example: A hacker attempting to exploit an unpatched web server vulnerability.


3. Identify Vulnerabilities

  • Assess weaknesses in systems, processes, or human behaviors that threats could exploit.
  • Conduct penetration testing, vulnerability scans, and security audits.

🔹 Example: Weak passwords, outdated software, misconfigured firewalls.


4. Assess Risk Likelihood & Impact

  • Likelihood: How probable is the threat exploiting a vulnerability?
  • Impact: What are the consequences (financial, reputational, operational)?

Risk Calculation Formula:

Risk=Likelihood×Impact\text{Risk} = \text{Likelihood} \times \text{Impact}

🔹 Example: If a phishing attack is likely and could lead to data breaches, the risk is high.


5. Determine Risk Level & Prioritize

  • Use a risk matrix (low, medium, high, critical) to rank risks.
  • Prioritize high-risk vulnerabilities with severe impact or high probability.

🔹 Example: A critical vulnerability in a public-facing web application should be addressed immediately.


6. Implement Risk Mitigation Strategies

Choose appropriate controls:

  • Avoid – Eliminate risky activities (e.g., disabling unused services).
  • Mitigate – Reduce risk through security controls (e.g., patching software, using firewalls).
  • Transfer – Shift risk to third parties (e.g., cyber insurance, outsourcing).
  • Accept – Acknowledge minor risks if mitigation is too costly.

🔹 Example: Deploying multi-factor authentication (MFA) to prevent unauthorized access.


7. Monitor & Review Continuously

  • Regularly reassess risks due to new threats and evolving attack methods.
  • Conduct continuous monitoring, incident response drills, and security updates.

🔹 Example: Monthly security assessments to check for new vulnerabilities.
