Infrastructure analysis

Networks are the backbone of every modern organization and institution. So an infrastructure analysis will start by identifying the following:

• Every network interface in the scope
• Routing information
• DNS servers and cashed DNS queries
• Proxy servers
• ARP entries

Not only network information but also identifying networking services is critical. They include the following:

• Listening services
• VPN connections
• Mapping the neighbor devices using protocols such as Cisco Discovery Protocol and Link Layer Discovery Protocol
