Internal Network Vulnerability Scanning and Management

PCI-DSS Requirement 11.3.1 compliant regular vulnerability scanning service

// 01 — Overview

Project Description

This project encompasses regular vulnerability scanning of servers, workstations, databases and network devices in the organization's internal network and management of identified findings according to risk levels.

PCI-DSS Requirement 11.3.1 mandates that organizations regularly scan their internal networks, evaluate results when new vulnerabilities emerge, and document remediation processes.

The solution is implemented with monthly or quarterly scans, remediation recommendations and closure reports.

// 02 — Methodology

Project Methodology

Comprehensive and regular vulnerability scanning approach

1

Asset Inventory and Scope Determination

All systems in the internal network are mapped, critical assets are identified and the scanning scope is clarified. CDE (Cardholder Data Environment) and non-CDE systems are separated.

2

Automated Vulnerability Scanning

Network devices, servers, databases and workstations are scanned using enterprise-grade vulnerability scanning tools. Credentialed scanning is performed.

3

Risk Assessment and Prioritization

Identified vulnerabilities are classified according to CVSS scores. Remediation priorities are determined by business impact analysis.

4

Remediation and Correction Support

Detailed remediation recommendations are provided for each vulnerability. Actionable remediation plans are prepared for technical teams.

5

Verification Scanning and Reporting

Verification scanning is performed after remediation. Trend analysis and executive summary reports are prepared.
