CISO Assistant Vulnerability Management

Vulnerability Management & Tool Integration GuideThis guide provides a structured workflow for bridging technical vulnerability findings with corporate risk oversight, focusing on automated ingestion and deduplicated remediation tracking.

1. Strategic Ingestion: Ingesting Tool Findings

CISO Assistant supports both manual and automated ingestion of vulnerability data from tools like Microsoft Defender, Nessus, and SonarQube.

A. Manual Batch Ingestion (Phase 1)

For initial establishment, you can import technical findings using standard batch files:

• Data Wizard: Use the "Import Vulnerabilities" feature in the sidebar to upload CSV or XLSX exports from your scanners.12

• Field Mapping: Ensure your export includes mandatory fields: name and severity (mapped to info, low, medium, high, or critical).1

B. Automated Pipeline (Phase 2 & Tier 3)

The Continuous SecOps tier utilizes a dedicated n8n Automation Engine to eliminate manual file handling.34

• The n8n Connector: A native n8n node intercepts raw JSON/CSV data directly from your scanners via API or webhook.23

• Dispatcher Service: For high-volume environments, a dockerized Dispatcher consumes messages from Kafka topics to update vulnerabilities and applied controls in real-time.1

2. Correlation & Ticket Optimization: "Minimum Fix Tickets"

To prevent "alert fatigue" and Jira sprawl, the platform employs a Vulnerability Clustering Engine.4

The Triage & Grouping Logic

1. Deduplication: The n8n engine applies deterministic filtering rules to intercept raw findings and filter out duplicates across different scan cycles.23

2. Deterministic Grouping: Findings are grouped by common patch requirements or CVE IDs rather than individual alerts.34

3. Contextual Triaging:

   • Automated Scoring: The system triages vulnerabilities based on the Affected Asset's Business Criticality rather than just the raw CVSS score.3

   • AI Auto-Triage (Tier 4): An optional AI module analyzes business context to prioritize fixes that impact critical production perimeters.23

3. Jira Synchronization Process

Once findings are grouped into actionable clusters, they are pushed to development squads.

• Clean Stream to Jira: n8n streams deduplicated "parent action plans" directly into Jira as structured fix tickets.34

• Status Sync: As squads close tickets in Jira, the n8n connector updates the vulnerability status in CISO Assistant to "Fixed," triggering an automatic update in your compliance dashboards.2

4. Policy-Driven Remediation Timelines

All remediated findings must adhere to the organizational Vulnerability & Patch Management Policy:15

Severity

CVSS Score

Remediation Deadline

Critical

9.0 - 10.0

48 Hours (or immediate compensating controls)

High

7.0 - 8.9

7 Days

Medium

4.0 - 6.9

30 Days

Low

0.1 - 3.9

90 Days (or next maintenance cycle)

Critical Gap Warning: Any vulnerability that cannot be patched within these timelines requires a Security Exception approved by the IT Security Team and documented within the platform's Exception domain.15

5. Managing False Positives (e.g., Microsoft Teams)

As noted in internal documentation, some tools may report "residual components" of legacy software as vulnerabilities even after patching.6

• Verification: Before escalating a ticket to a squad, use the Review Submissions workflow to confirm the finding represents a genuine risk.6

• X-Ray Validation: Run an X-Ray scan to identify findings marked as "Fixed" that lack updated scanner evidence.6

n8n Workflow Logic: Vulnerability Grouping & Jira Sync

To minimize ticket sprawl, the n8n automation acts as an "Intelligent Buffer." Instead of creating a ticket for every CVE, it groups findings into Actionable Parent Tickets based on shared remediation context.

1. Ingestion & Normalization

• Trigger: The workflow is triggered by an HTTP Webhook (for tools like SonarQube) or a Cron schedule (for Microsoft Defender/Nessus API).

• Normalization: A "Function Node" maps varying tool outputs into a standard JSON schema:

  • cve_id, cvss_score, affected_asset, remediation_patch.

2. The Grouping Logic (Deduplication)

The core "Aggregation Node" uses the following logic to consolidate findings:

• Primary Key: remediation_patch + affected_asset.

  • Logic: If 50 vulnerabilities on the "Patient Portal" are all fixed by updating the "OpenSSL Library," the workflow creates one Jira ticket.

• Secondary Key (For OS/Infra): host_id.

  • Logic: All missing patches for a single Linux Server are grouped into one "Monthly Maintenance" ticket for the SysAdmin squad.

3. Jira Ticket Construction

The "Jira Node" creates a ticket with the following structure:

• Summary: [SEC] - Update {Library/Package} on {Asset_Name} - {Max_Severity}

• Description:

  • "This ticket consolidates {Count} vulnerabilities."

  • Included CVEs: {List of CVE-202X-XXXX}

  • Remediation: {Standardized Patch Instructions}

  • Deadline: {Calculated based on the highest severity in the group per policy}

• Linkage: The Jira Ticket ID is written back to each vulnerability record in CISO Assistant for 2-way syncing.

4. Automated Status Sync

• Jira Webhook: When a developer moves the ticket to "Done," Jira sends a webhook back to n8n.

• CISO Assistant Update: The workflow identifies all vulnerabilities linked to that Jira ID and updates their status to "Fixed" or "Remediated" in the platform.1

Vulnerability Management Dashboard Reference

Once ingested, you can track these through the following CISO Assistant views:

• Vulnerabilities Domain: View the raw list of technical findings and their associated severity scores.1

• Applied Controls: View the "Patch Management" control to see which vulnerabilities are currently covered by active maintenance tasks.1

• X-Rays: Use the "Review Staleness" check to flag any vulnerability that has exceeded its 48-hour (Critical) or 7-day (High) remediation deadline.1

Jira Issue Template: Vulnerability Remediation

To ensure your development squads have the full context required to remediate vulnerabilities without needing to log into multiple tools, use the following template for your n8n-generated Jira tickets.

Summary

[SEC-FIX] - {Action: Update/Configure} {Package/Service} on {Asset_Name} - {Max_Severity}

Description

[Overview]

This ticket has been automatically generated and consolidated by CISO Assistant to address {Count} security vulnerabilities identified on {Asset_Name}.

• Primary Asset: {Business_Service_Impacted}

• Related Control: {Applied_Control_Name (e.g., A.8.8 Management of technical vulnerabilities)}1

[Remediation Status Sync]

Moving this ticket to "Done" will automatically update the vulnerability status to "Fixed" in CISO Assistant and resolve the corresponding X-ray integrity warnings.1

Key Workflow Reminders for Squads

• Evidence of Fix: If a re-scan is not scheduled immediately, please attach a screenshot of the updated version string or a local scan result to this ticket.12

• Exceptions: If this fix cannot be implemented by {Due_Date} due to breaking changes, please notify the Security Team to document a Security Exception in CISO Assistant.2

• Verification: Once resolved, the X-rays feature will verify the fix against the next tool ingestion. Any residual components flagged will re-open this ticket or create a follow-up.12

Configuring Jira Status Synchronization with CISO Assistant

To enable two-way synchronization, where closing a Jira ticket automatically updates the vulnerability status in CISO Assistant, you must configure a Jira Webhook that sends data back to your n8n automation engine.

Step 1: Create the Webhook URL in n8n

1. Open your n8n workflow and add a Webhook Node at the start of your "Status Sync" branch.1

2. Set the HTTP Method to POST.

3. Copy the Production Webhook URL provided by the node.

Step 2: Configure the Webhook in Jira

1. Log in to Jira with Administrative privileges.

2. Navigate to System Settings > Advanced > Webhooks.

3. Click Create a Webhook and provide the following details:

   • Name: CISO Assistant Status Sync

   • URL: Paste the URL from n8n.

   • Events: Select Issue: updated (and optionally Issue: deleted).

   • JQL Filter: Limit the scope to security tickets to reduce noise: project = "SEC" AND status changed to "Done".

Step 3: Map Jira Data to CISO Assistant Actions

In your n8n workflow, use the incoming Jira data to trigger the CISO Assistant API. The workflow should follow this logic:

1. Extract the Jira ID: Get the issue key from the webhook payload.1

2. Filter for "Done": Ensure the status field in the webhook is set to your "Fixed" or "Done" equivalent.

3. Update CISO Assistant: Use the CISO Assistant Node (or a generic HTTP node) to update the vulnerability record.12

   • Resource: Vulnerability

   • Operation: Update

   • Status: Set to fixed.13

   • Matching: Use the Jira Ticket ID stored in the CISO Assistant ref_id or a custom field to find the correct record.1

Step 4: Verify with X-Rays

Once the sync is active, CISO Assistant's X-rays will automatically monitor the integrity of the fix.1

• Logical Validation: If a ticket is marked "Fixed" but the next scanner ingestion still shows the vulnerability, the "Review Staleness" or "Evidence Gap" X-ray will flag the inconsistency for the Security Team.1

• Automatic Resolution: When the scan confirms the fix, the X-ray warning will clear automatically, and the Applied Control for "Technical Vulnerability Management" will reflect the updated compliance status.1
