Network Security Audit

World Class Network Security Audit

Altius IT's network security audit evaluates the security of your network infrastructure, the firewalls, routers, switches, wireless access points, VPN gateways, and segmentation architecture that form the backbone of your IT environment.

Every system, application, and data flow in your organization depends on the network. If the network is compromised, everything connected to it is at risk.

Our CISA-certified auditors examine how your network is designed, configured, and monitored to ensure it provides a secure, segmented, and resilient foundation for your operations. Our proprietary audit process covers your complete network security posture:

Network Infrastructure Security

• Firewall rule review and optimization – including rule base analysis, unused rules, overly permissive rules, and rule ordering
• Network architecture and segmentation analysis – including VLANs, subnets, DMZ design, and microsegmentation
• Router and switch security configurations – hardening, firmware currency, and management access controls
• Wireless network security – including encryption standards, rogue access point detection, and guest network isolation
• VPN configuration and remote access security – including encryption protocols, split tunneling policies, and authentication strength
• DNS security – including DNSSEC, DNS filtering, and protection against DNS-based attacks
• Certificate management – for network services, including TLS/SSL configuration and certificate expiry monitoring

Network Monitoring and Detection

• Intrusion detection and prevention system (IDS/IPS) – deployment and tuning
• Network monitoring and traffic analysis – capabilities, including NetFlow, packet capture, and anomaly detection
• Network device logging – audit trail integrity, and centralized log management
• Network access control (NAC) – policies and enforcement

External and Internal Network Security

• External network security audit – clients provide their public-facing IP addresses, and our auditors evaluate them for vulnerabilities, exposed services, open ports, misconfigurations, and weak encryption
• Internal network security audit – evaluation of internal segmentation, lateral movement risk, and internal access controls

Add a Penetration Test

A penetration test can be added to your network security audit to validate your network defenses against real-world attack scenarios. Our penetration testing includes network perimeter testing, segmentation validation, and firewall bypass assessment. Contact us to discuss adding a penetration test to your network security audit engagement.

Our report identifies specific vulnerabilities and provides detailed instructions to mitigate or eliminate each risk.
