6 Core Pillars of Firewall & Network Auditing
Our certified network security engineers and firewall architects analyze rulebases, inspection profiles, and routing policies to eliminate security exposure.
Rulebase Optimization & Pruning
Algorithmic analysis of shadowed, redundant, expired, and overly permissive (ANY-ANY-ALLOW) rules to eliminate performance latency and close accidental backdoors.
- Shadowed & duplicate rule identification
- Unused & expired rule cleanup
- Overly broad ANY-ANY rule remediation
NGFW Deep Packet Inspection
Auditing SSL/TLS decryption policies, IPS/IDS signature updates, application ID (App-ID) enforcement, and DNS sinkholing to block command-and-control (C2) beacons.
- SSL/TLS inbound/outbound decryption check
- IPS/IDS active prevention verification
- Malicious URL filtering & DNS sinkholing
DMZ & Micro-Segmentation
Evaluating network zoning architectures, DMZ isolation from core internal LANs, cloud VPC security groups, and stopping lateral adversary movement.
- DMZ to Internal LAN isolation audit
- East-West lateral movement restrictions
- Cloud VPC & hybrid network security groups
Appliance OS & Admin Hardening
Verifying management interface binding to dedicated OOB networks, disabling insecure protocols (Telnet/HTTP), enforcing TACACS+/MFA, and applying OS CVE hotfixes.
- Out-of-band management plane protection
- TACACS+ / RADIUS with MFA enforcement
- Firewall firmware CVE vulnerability patch check
PCI-DSS & RBI Compliance
Validating documented firewall change management processes, semi-annual rule reviews, cardholder data environment (CDE) boundaries, and SIEM logging.
- PCI-DSS Requirement 1 compliance check
- RBI Cyber Security Framework validation
- Firewall change approval audit trails
CLI Clean-Up & Safe-to-Host
Delivering vendor-specific CLI configuration commands (Palo Alto, FortiGate, ASA), conducting post-patch retesting, and issuing the Safe-to-Host Certificate.
- Ready-to-execute CLI cleanup scripts
- Free 30-day rule retesting verification
- CERT-In Safe-to-Host Firewall Certificate
5-Stage Firewall Review & Assessment Roadmap
Our certified network security specialists execute a non-disruptive, offline configuration evaluation lifecycle.
Rulebase & Architecture Scoping
Collecting sanitized firewall configuration files (XML / CLI dumps), routing tables, and network topology diagrams under strict NDA without live network impact.
Algorithmic Shadowing & Pruning Analysis
Processing configuration files with automated analytics engines to identify shadowed rules, unused objects, and calculate rulebase complexity scores.
Zero-Trust & Deep Packet Inspection Review
Senior network security auditors manually evaluate DMZ boundaries, IPS profiles, SSL decryption rules, and administrative access controls.
Actionable Remediation & Pruning Guide
Delivering prioritized CVSS v3.1 reports with vendor-tailored CLI commands, helping network engineers prune rules with zero operational downtime.
Verification & Compliance Attestation
Validating updated rulebases during a 30-day retest window and issuing the official Lumiverse Safe-to-Host Network Security Certificate.
