Exposure Analysis

Prev Next

You can find these options in the Exposure Analysis menu.

Overview

Exposure Analysis helps you estimate the risk-based exposure score (on a 1–100 scale) for a specific CVE on a given asset. It models how multiple factors, including asset attributes, vulnerability characteristics, threat intelligence, and the effectiveness of security controls, influence that score.

This tool offers a quick, “back-of-the-envelope” way to explore different what-if scenarios and understand how changes to these factors may affect exposure. Results are approximate and intended for exploratory analysis. They may differ from the actual exposure scores calculated for vulnerability instances in your environment, which use more detailed control mappings and context-specific data.

What You Can Do Here

  • Simulate risk impact for specific vulnerabilities using the Exposure Simulations interface.

  • Select a CVE and asset to define the scope of the simulation.

  • Adjust Asset Attributes to model contextual conditions.

  • Modify Vulnerability Analysis parameters to reflect exploitability and relevance.

  • Configure Threat Level to model different attacker intents.

  • Set Security Controls Efficacy and Validation to evaluate defensive posture.

  • Analyze calculated exposure in the Exposure Score Calculation panel.

  • Evaluate exposure dynamics over time using the Exposure Score with Age chart.

Asset Attributes

In this section you can select the CVE you want to include in the simulation, and a related asset. You can also select the role of the asset, and any tags. You can then proceed to indicate the impact level of the asset, the network zone/subzone, and the component (user component or kernel component).

Vulnerability Analysis

In the Vulnerability Analysis section, you can configure the following parameters:

  • Attack Vector

  • Dependencies

  • Scope

  • Privileges Required

  • Interaction Required

  • Attack Complexity

  • Confidentiality

  • Integrity

  • Availability

  • Vulnerability Age

Threat Level

In this section you can configure the threat chatter level, as well as the EPSS level. You can also select the following threat tags: ransomware, malware, CISA KEV, known exploit.

Security Controls Efficacy and Validation

In this section you can configure the following parameters to simulate the efficacy of your controls in place:

  • EDR

  • Firewall

  • Segmentation

  • Zero Trust

  • Simulation Validation

  • Testing Validation

How To Use the Security Control Efficacy Sliders

Each slider (EDR, Firewall, Segmentation, Zero Trust) represents the assumed efficacy (effectiveness) percentage of that specific security control against the Tactics, Techniques, and Procedures (TTPs) associated with the vulnerabilities being analyzed, within a range of 0-100%:

  • 0% = The control provides no mitigation

  • 100% = The control fully mitigates the threat (resulting in Likelihood = 0% and Exposure Score = 1)

The sliders let you easily adjust control efficacy values to explore “what-if” scenarios:

  • Single control modeling: Adjust one slider to see the impact of deploying or improving that control

  • Layered defense modeling: Adjust multiple sliders simultaneously to see the combined effect of multiple controls

  • Comparison scenarios: Reset and adjust different combinations to compare security postures

The Exposure Analysis tool will recalculate the Exposure Score based on your adjustments, making it easy to demonstrate the value of security investments to stakeholders.

Important: All Controls Are Treated Equally in This Tool

In the Exposure Analysis modeling interface, all four control sliders have the same impact on the Exposure Score calculation. Moving EDR from 0% to 50% produces the same effect as moving Firewall, Segmentation, or Zero Trust from 0% to 50%. This simplified approach makes the tool easy to use for quick scenario modeling.

Exposure Score Calculation

This section shows you the result of the simulation. It will show you the final Exposure Score resulting from the parameters you configured.

Input Parameters and Effect

Section

Parameter

Description

Effect

Asset Attributes

Role

Business roles associated with the asset (e.g., RDP, Admin)

Directly influences severity calculations through role-based impact weights

Asset Attributes

Tags

Asset classification tags (e.g., BU Sales, Marketing, Environment/Office), Base asset impact rating

Used for asset categorization and reporting

Asset Attributes

Impact Level

Base asset impact rating

Forms foundation for impact score calculation

Asset Attributes

Zone/Subzone

Network segmentation location (e.g., Perimeter, Core, Air gapped)

Significantly affects accessibility scores; deeper zones reduce exposure

Asset Attributes

Component

System component type (e.g., User Component, Kernel)

Kernel components increase severity score; user components have baseline severity

Vulnerability Analysis

Attack Vector

Initial access method (e.g., Network, Local)

Remote vectors increase accessibility; local vectors reduce exposure

Vulnerability Analysis

Dependencies

Required preconditions (e.g., Known Dependencies)

Additional dependencies decrease likelihood

Vulnerability Analysis

Scope

Impact scope (e.g., Unchanged, Changed)

Changed scope increases severity rating

Vulnerability Analysis

Privileges Required

Access level needed (None, Low, High)

Higher privileges decrease likelihood score

Vulnerability Analysis

Interaction Required

User interaction needs (None, Required)

Required interaction reduces exposure score

Vulnerability Analysis

Attack Complexity

Exploitation difficulty (Low, High)

Higher complexity reduces likelihood score

Vulnerability Analysis

CIA Ratings

Confidentiality, Integrity, Availability impact levels

Directly influences severity calculation

Threat Level

Threat Chatter

Observed threat actor interest (0-100)

Higher chatter increases threat score

Threat Level

EPSS

Exploit probability scoring (0-1)

Directly influences threat calculation

Threat Level

Threat Tags

Associated threat categories (e.g., Ransomware, CISA KEV)

CISA KEV maximizes visibility; other tags increase threat score

Security Controls

Control Efficacy

Effectiveness ratings for security controls (0-100%)

Directly reduces likelihood through mitigation factor

Security Controls

Validation

BAS and Red Team testing results

Failed tests override control efficacy; successful tests confirm effectiveness

Security Controls

Segmentation

Network isolation controls

Provides up risk reduction when properly implemented

Exposure Score with Age

The graph plots Exposure Score against Vulnerability Age (in days), demonstrating how the cybersecurity risk evolves over time. It shows two potential measures: Exposure Score (Inherent) in red and Exposure Score (Mitigated) in blue.

Use of the Exposure Analysis Tool

Modeling Tool vs. Production Calculation

Exposure Analysis is a “back-of-the-envelope” analysis tool that allows you to model different scenarios in real time with some level of approximation. It should not be confused with how Balbix calculates exposure score for your actual vulnerability instances, which is more complete and comprehensive.

How Balbix Actually Calculates Exposure Score

In our standard pipeline, Balbix:

  1. Automatically maps every CVE to its associated TTPs

  2. Derives control efficacy values from authoritative sources like MITRE Engenuity evaluations

  3. Evaluates control efficacy based on which specific TTPs each control is effective against (e.g., EDR is more effective against execution/persistence TTPs, while Firewall is more effective against C2/exfiltration TTPs)

  4. Calculates efficacy for each vulnerability instance on each asset

  5. Factors in additional context: vulnerability tags (CISA KEV, Ransomware, etc.), asset role, network zone, business context, and threat intelligence
