What is Network Vulnerability Assessment & How Does It Work?
Infrastructure and Network Security Testing
Identify and remediate weaknesses across your network and infrastructure by simulating real-world attacker behavior.
TABLE OF CONTENT
Why it matters
Infrastructure and network environments remain a primary target for attackers seeking initial access, privilege escalation, and lateral movement.
Infrastructure and network security testing helps organizations address these risks by:
Reducing the expanding infrastructure attack surface
Hybrid environments spanning on-premises systems, cloud platforms, and remote access points increase exposure to attacks.
Identifying misconfigurations across networks and systems
Weak configurations, exposed services, and poor segmentation can create easy entry points for attackers.
Uncovering lateral movement pathways
Attackers often exploit internal trust relationships to reach high-value systems once inside the network.
Validating the effectiveness of security controls
Test whether firewalls, monitoring systems, and access controls can detect and stop real attack techniques.
Our Approach
SISA's 5-Step Testing Approach
Our infrastructure and network security testing follows a structured, attacker-informed methodology to uncover real security risks.
Identify in-scope internal and external assets, exposed services, network entry points, and reachable systems to ensure comprehensive testing coverage.
Perform controlled vulnerability discovery and configuration reviews across servers, network devices, and infrastructure components to identify weaknesses.
Simulate real-world attacker techniques to gain initial access, escalate privileges, and move laterally across the network.
Validate how far an attacker could progress within the environment and prioritize findings based on exploitability, exposure, and business impact.
Deliver clear, evidence-backed findings with prioritized recommendations to strengthen infrastructure security and reduce risk.
Service Offerings
Our services are designed to uncover vulnerabilities, misconfigurations, and exploitable pathways across networks, systems, and infrastructure components.
Network Vulnerability Assessment
Identify weaknesses across internal and internet-facing network assets, including exposed services, outdated software, insecure protocols, and common configuration flaws.
Network Penetration Testing
Simulate real-world attack techniques to test authentication controls, segmentation effectiveness, privilege escalation paths, and lateral movement within the network.
Server Configuration Review
Assess operating system hardening, access controls, patch management, and logging configurations to identify weaknesses that could expose critical systems.
Firewall & Network Device Configuration Review
Review firewall rules, segmentation policies, and device configurations to identify overly permissive access, misconfigurations, and gaps in network defenses.
Wireless Security Testing
Evaluate wireless network security, including encryption mechanisms, access point configurations, rogue devices, and segmentation controls.
PCI ASV Scanning
Perform certified external vulnerability scans to identify security weaknesses in internet-facing systems and ensure compliance with PCI DSS ASV requirements.
BENEFITS
By identifying exploitable weaknesses across networks, systems, and security controls, organizations gain actionable insights that improve resilience against real-world attacks.
Reduced risk of unauthorized network access
Stronger enforcement of network security boundaries
Early identification of exploitable weaknesses
Improved prioritization of remediation efforts
Greater confidence in infrastructure security posture
WHY SISA
SISA’s infrastructure and network security testing services go beyond automated scans and combine attacker-driven techniques with risk-based analysis to uncover real, exploitable weaknesses.
Attacker-led testing that mirrors real intrusion techniques:
Assess networks and infrastructure from an adversary’s perspective to identify realistic attack paths and weaknesses.
Risk-based analysis aligned to asset criticality:
Findings are evaluated based on exposure, exploitability, and the importance of affected systems to business operations.
Manual validation to eliminate false positives:
Security experts validate vulnerabilities through controlled testing to ensure findings reflect real risk.
Focus on attacker movement and access paths:
Assess how attackers could escalate privileges, bypass controls, and move laterally toward critical assets.
Actionable remediation guidance:
Deliver clear, prioritized recommendations that help teams effectively strengthen network and infrastructure security.
