Abstract
Systems and methods for discovery and mapping of industrial control and SCADA networks are described herein. The disclosed systems and methods help operators ensure the cyber security of their SCADA network through accurate discovery, fingerprinting and mapping the industrial control network map, including PLCs (Programmable Logic Controller) and RTUs (Remote Terminal Unit), using passive techniques.
Claims22
A method for discovering topology of a network comprising a Layer 3 and a Layer 2, the method comprising:
- employing at least one hardware processor for:
- discovering a first Layer 3 network topology by examining routing protocols using route analytics method;
- discovering a second Layer 3 network topology using information from at least one of Simple Network Management Protocol (SNMP) and Source Shell/Command Line Interface/Telnet login to a router;
- and
- merging and deduplicating the first discovered Layer 3 network topology and the second discovered Layer 3 network topology to obtain a resultant Layer 3 network topology that includes a plurality of routers and associated links between the routers.
A system for discovering topology of a network comprising a Layer 3 and a Layer 2, the system comprising:
- at least one hardware processor, and computer readable storage medium having computer readable instructions stored thereon for execution by the processor, causing the processor to:
- discover a first Layer 3 network topology by examining routing protocols using route analytics method;
- discover a second Layer 3 network topology using information from at least one of Simple Network Management Protocol (SNMP) and Source Shell/Command Line Interface/Telnet login to a router;
- and
- merge and deduplicate the first discovered Layer 3 network topology and the second discovered Layer 3 network topology to obtain a resultant Layer 3 network topology that includes a plurality of routers and associated links between the routers.
A network comprising a plurality of routers, comprising:
- a system for discovering topology of a network comprising a Layer 3 and a Layer 2, the system comprising:
- at least one hardware processor, and computer readable storage medium having computer readable instructions stored thereon for execution by the processor, causing the processor to:
- discover a first Layer 3 network topology by examining routing protocols using route analytics method;
- discover a second Layer 3 network topology using information from at least one of Simple Network Management Protocol (SNMP) and Source Shell/Command Line Interface/Telnet login to a router;
- and
- merge and deduplicate the first discovered Layer 3 network topology and the second discovered Layer 3 network topology to obtain a resultant Layer 3 network topology that includes a plurality of routers and associated links between the routers.
