OWASP Risk Assessment Basics

The Open Web Application Security Project (OWASP) is a worldwide not-for-profit organization focused on improving the security of software. The OWASP Top 10 is a regularly-updated report outlining the ten most critical security risks to web applications. Understanding risk assessment is crucial for mitigating these risks effectively.

Definitions

• Risk: The potential for loss or damage when a threat exploits a vulnerability.
• Threat: Any circumstance or event with the potential to adversely impact organizational operations.
• Vulnerability: A weakness in a system that can be exploited by a threat.
• Impact: The effect or consequence of an event, measured in terms of harm or damage.

Step-by-Step Risk Assessment

1. Identify Assets: List all assets that require protection, such as data, applications, and infrastructure.
2. Identify Threats: Determine potential threats to each asset, such as cyber attacks, natural disasters, or insider threats.
3. Assess Vulnerabilities: Evaluate existing vulnerabilities that could be exploited by identified threats.
4. Analyze Impact: Assess the potential impact of successful exploitation on the organization.
5. Assess Likelihood: Estimate the likelihood of each threat exploiting a vulnerability.
6. Determine Risk Level: Combine impact and likelihood to determine overall risk levels (e.g., low, medium, high).
7. Implement Mitigation: Develop and implement strategies to mitigate identified risks.

• Conduct regular risk assessments to stay updated on new threats.
• Involve stakeholders from different departments for a comprehensive view.
• Use automated tools to help identify vulnerabilities and manage risks efficiently.
• Train staff on security awareness to reduce human errors.
• Document the entire process for accountability and future reference.
