Network Security Audit: Finding the “Silent Killer” Misconfigurations in Your Infrastructure

Let's be real: When you think about network security, you probably imagine some complex firewall or next-gen AI system. But here’s the truth - the biggest risk to your digital infrastructure is often the most basic one: internal misconfiguration and poor hygiene. I've seen it countless times across industries, from high-stakes finance to cutting-edge gaming: brilliant teams focused on innovation, unknowingly leaving a backdoor wide open simply because their network wasn't properly checked after the last big update. It's a gift to a threat actor.  

The Network: The Hacker's Map

A Network Audit, as we define it at Cyrex, isn't just a compliance checkbox. It's a proactive mapping of your entire digital ecosystem. Think of your network as the nervous system of your business. If the components aren't speaking correctly, or if one junction is unprotected, the whole system is at risk. We don't just look for known vulnerabilities. We simulate a malicious attacker walking the internal halls of your digital property, checking:
  • Interconnected systems and their access controls (e.g., databases with direct connections to production environments)
  • Exposed services that create unnecessary attack surfaces (e.g., Forgotten test servers with administrative interfaces visible to the public)
  • Outdated protocols that have documented vulnerabilities (e.g., Legacy SMBv1 file sharing protocol still active on internal networks)
  • Misconfigurations that bypass intended security measures (e.g., Firewall rules allowing overly permissive outbound connections)
  • Undocumented network segments operating in the shadows (e.g., Shadow IT deployments running unauthorized cloud services)

Your Attack Surface

Your network's attack surface exists in layers, each requiring distinct security approaches. External-facing assets - your websites, APIs, and remote access points - represent your first line of defense and typically warrant priority testing. These are the entry points attackers probe first, looking for that initial foothold. However, internal systems often hide the most critical vulnerabilities. Once perimeter defenses are breached, loosely secured internal assets like domain controllers, file shares, and employee workstations become prime targets for lateral movement. Our staged approach first secures your perimeter, then works inward. Modern networks extend beyond traditional boundaries into cloud infrastructure. We examine your AWS, Azure, or Google Cloud deployments for misconfigurations specific to these environments - like excessive IAM permissions, unencrypted storage, or insecure API gateways - that create unique security challenges invisible to conventional network checks.
