Network Vulnerability Assessment

A Network Vulnerability Assessment is a proactive security service that identifies, classifies, and prioritizes weaknesses across your internal and external network infrastructure. Unlike penetration testing, which simulates attacks, vulnerability assessments provide a broad and systematic scan to uncover misconfigurations, outdated software, exposed ports, and unpatched systems. Our assessments help you understand your risk exposure and take timely action to secure your network.

What We Assess

• Internal Networks: Servers, switches, workstations, shared drives, and domain controllers within your LAN
• External Networks: Internet-facing IPs, firewalls, VPNs, and web servers vulnerable to public threats
• Cloud Networks: Misconfigured security groups, open storage buckets, exposed services (AWS, Azure, GCP)
• Wireless Networks: Rogue access points, insecure protocols (WEP/WPA), and signal leaks
• Device & OS Vulnerabilities: Missing patches, outdated firmware, and insecure configurations on routers, firewalls, and endpoints

Assessment Methodology

1. Discovery & Scanning
   • Use industry-standard tools (e.g., Nessus, OpenVAS, Qualys) to map your network and scan for known vulnerabilities
2. Validation & Analysis
   • Analyze findings to reduce false positives and focus on actual risk
   • Classify vulnerabilities by severity using CVSS scoring
3. Reporting & Recommendations
   • Deliver a detailed report with affected systems, risk levels, and actionable remediation steps
   • Optional executive summary for leadership and board-level reporting
4. Remediation Support
   • Work with your team to prioritize and patch vulnerabilities
   • Optional retesting to confirm remediation

Benefits of Network Vulnerability Assessment

• 🔍 Complete Visibility: Gain insight into every exposed device, service, and configuration issue
• 🛠️ Prioritized Remediation: Focus on fixing high-risk vulnerabilities first
• 🧩 Supports Continuous Security: Ideal for quarterly or monthly risk tracking
• ✅ Regulatory Alignment: Helps meet the requirements of PCI DSS, HIPAA, ISO 27001, SOC 2, and NIST
• 🚨 Reduced Breach Risk: Prevents attackers from exploiting known weaknesses

Network Penetration Testing

Network Penetration Testing simulates real-world attacks on your internal and external network infrastructure to identify exploitable vulnerabilities, misconfigurations, and weaknesses in your security controls. Unlike automated vulnerability scans, this service involves hands-on techniques used by ethical hackers to mimic actual threat actors—helping you understand how deep an attacker could go and what data they could access. We test your environment from both outside (external pentest) and inside (internal pentest) the network to provide a full view of your organization’s security posture.

Types of Network Penetration Testing

1. External Network Penetration Testing
   • Simulates attacks from the public internet, targeting systems exposed to the outside world (e.g., firewalls, VPNs, web servers, email gateways).
   • Evaluates:
     • Public IP exposure
     • DNS misconfigurations
     • SSL/TLS issues
     • Brute-force vulnerabilities
     • Web app security entry points (if present)
2. Internal Network Penetration Testing
   • Simulates an attacker who has gained internal access (via phishing, rogue device, or compromised user account).
   • Evaluates:
     • Access to shared drives and critical data
     • Lateral movement and pivoting
     • Insecure network shares
     • Weak Active Directory configurations
     • Poorly segmented VLANs
     • Password reuse and hash dumping (e.g., NTLM, Kerberos)
3. Wireless Network Penetration Testing
   • Focuses on Wi-Fi networks, evaluating encryption protocols, rogue APs, and wireless authentication.
   • Evaluates:
     • Weak Wi-Fi encryption (e.g., WEP, WPA1)
     • Rogue access points
     • Evil twin/honeypot attacks
     • Signal leakage beyond physical premises
     • Guest network segmentation
4. Remote Access & VPN Penetration Testing
   • Assesses the security of remote access systems such as VPNs, RDP, and VDI.
   • Evaluates:
     • MFA enforcement
     • Misconfigured VPN appliances
     • Brute-force/RDP vulnerabilities
     • Client-side misconfigurations
5. Network Device & IoT Penetration Testing
   • Targets routers, switches, firewalls, VoIP, printers, and IoT devices.
   • Evaluates:
     • Default credentials
     • Firmware vulnerabilities
     • Open ports and weak SNMP configurations
     • Outdated software on network appliances
6. Social Engineering (Add-On Option)
   • Simulates human-based attacks such as phishing or USB drops to evaluate internal network compromise pathways.
   • Optional but powerful complement to technical pentests.

Testing Methodology (Expanded)

1. Scoping & Planning
   • Define goals: compliance, risk validation, red teaming, etc.
   • Identify in-scope systems: internal/external IPs, domains, apps, and users
   • Choose testing type: Black-box, Grey-box, or White-box
2. Reconnaissance (Passive & Active)
   • DNS enumeration, WHOIS, Shodan/OSINT collection (external)
   • Network mapping: ARP scans, traceroutes, port scanning (internal)
   • Identify services, banner grabbing, and host fingerprinting
3. Vulnerability Scanning & Enumeration
   • Use tools like Nmap, Nessus, OpenVAS, Nikto, and custom scripts
   • Identify open ports, OS versions, running services, and known CVEs
   • Enumerate shares, SMB, RDP, RPC, SNMP, LDAP, etc.
4. Exploitation
   • Use ethical exploitation tools (e.g., Metasploit, Responder, CrackMapExec)
   • Exploit vulnerabilities in unpatched systems, weak protocols, or misconfigurations
   • Bypass firewalls, gain unauthorized access, and simulate data exfiltration
   • Capture NTLM hashes, poison LLMNR/NBT-NS, or abuse misconfigured trust relationships
5. Post-Exploitation
   • Privilege escalation (horizontal and vertical)
   • Credential harvesting and lateral movement
   • Domain compromise simulation (e.g., DCSync, Kerberoasting)
   • Access to sensitive data and critical infrastructure
6. Cleanup
   • Restore systems to pre-test state
   • Remove all test accounts, tools, and scripts
   • Ensure no residual impact on performance or integrity
7. Reporting

Firewall Rule Review Services

Your firewall is your network’s first line of defense—but if its rules are outdated, overly permissive, or misconfigured, it can become a serious security liability. Our Firewall Rule Review Services evaluate the effectiveness, accuracy, and security of your firewall configurations to ensure they align with best practices, compliance requirements, and your business objectives.

We review both internal and perimeter firewalls (hardware or cloud-based) across vendors like Cisco, Fortinet, Palo Alto, Juniper, Sophos, Check Point, and AWS/Azure firewalls.
