Variable calculateOverallSecurityLevel

Type Declaration

• • (
        availabilityLevel: SecurityLevel,
        integrityLevel: SecurityLevel,
        confidentialityLevel: SecurityLevel,
    ): SecurityLevel

  • Calculates the overall security level based on individual CIA components

    Computes a composite security level by averaging the numeric values of availability, integrity, and confidentiality levels, then rounding to the nearest security level. Provides a single metric for overall security posture.

    Parameters

    • availabilityLevel: SecurityLevel

      Availability security level

    • integrityLevel: SecurityLevel

      Integrity security level

    • confidentialityLevel: SecurityLevel

      Confidentiality security level

    Returns SecurityLevel

    The overall security level (average of the three components, rounded)

    Example

    // All equal - returns same level
    calculateOverallSecurityLevel('High', 'High', 'High')  // 'High'
    
    // Mixed levels - returns average
    calculateOverallSecurityLevel('Low', 'Moderate', 'High')  // 'Moderate'
    calculateOverallSecurityLevel('None', 'Low', 'Low')       // 'Low'
    
    // Use for system-wide security assessment
    const overallLevel = calculateOverallSecurityLevel(
      availabilityLevel,
      integrityLevel,
      confidentialityLevel
    );
    console.log(`System security level: ${overallLevel}`);
