It is utmost important for any security engineer to understand their network first before securing it and it becomes a daunting task to have a ‘true’ understanding of a widespread network. In a mid to large level organisation’s network having a network architecture diagram doesn’t provide the complete understanding and manual verification is a nightmare. Hence in order to secure entire network it is important to have a complete picture of all the systems which are connected to your network, irrespective of their type, function, techology etc.
BOTTOM LINE - YOU CAN'T SECURE WHAT YOU ARE NOT AWARE OF.
Let’s Map Your Network (LMYN) aims to provide an easy to use interface to security engineer and network administrator to have their network in graphical form with zero manual error, where a node represents a system and relationship between nodes represent the connection.
LMYN does it in two phases:
Monitoring: This is a continuos process, where LMYN monitors the 'in-scope' network for any changes, compare it with existing information and update the graph database accordingly. Below technologies have been used in the tool:
