LAN Penetration Test
A LAN penetration test (LAN pentest) targets your internal network security. This includes your WiFi network and the connections between remote workstations and cloud services or data centers. In essence, a LAN pentest is similar to a WAN test, except it is performed from the inside out.
While IT administrators often secure external access well, many internal services and ports are unintentionally left open. A LAN pentest evaluates the security of all potential internal access points.
We typically conduct these tests on-site using our own equipment. Alternatively, we can set up a temporary system, often called a “stepping stone”, to perform the test remotely. This means we can carry out LAN penetration tests anywhere in the world without the need for travel.
Why Do You Need a LAN Penetration Test?
A LAN pentest is essential to understand the internal security risks facing your organization. One key aspect is ensuring your internal networks are properly segmented and not unintentionally interconnected. When networks are too intertwined, viruses or ransomware can spread quickly across systems.
A well-known example is the 2017 WannaCry virus, which rapidly infected organizations worldwide and caused massive disruption.
What Do We Test?
During a LAN pentest, we assess a wide range of security concerns, such as:
How easily can someone access the WiFi network? And what can users access via guest WiFi?
- Does the system administrator’s documentation match the devices actually found on the network?
Are employee internet connections adequately secured?
In larger organizations, we often find thousands of vulnerabilities. The rise of the Internet of Things (IoT) increases risk, as more devices connect to the internet unnecessarily. We highlight the most critical risks and, if desired, assist in mitigating them after the test.
Combining LAN and WAN Pentests
A LAN pentest can be effectively combined with a WAN pentest for a comprehensive assessment. After these, you might also consider our ICCM audit, which focuses on the human element of cybersecurity.
This includes evaluating password policies, IT management practices, and the overall maturity of your organization’s cybersecurity setup—such as removing redundant access rights.
