SeNet International attended the Association of California Water Agencies (ACWA) conference and exhibition on November 28 through December 1 in Anaheim, CA. Rehan Bashir and Steve Davis presented at the conference on why cyber security is imperative in both information and operation technology segments in water districts.
ICS and SCADA networks are often the most critical components of an organization’s IT environment. Unfortunately, for a variety of reasons, these systems do not often undergo comprehensive, active security testing. One of SeNet’s approaches to assessing the security posture of ICS/SCADA environments is to perform a passive security review using a tool such as GrassMarlin.
GrassMarlin was developed by the National Security Agency (NSA) to provide situational awareness for ICS/SCADA system environments. It is a lightweight Java-based graphical tool that passively sniffs traffic on an ICS/SCADA network to create logical and physical graphs. GrassMarlin runs both in Windows and Linux-based operating systems. Graphs in GrassMarlin can be generated by pointing it to already captured packet files (PCAPs). Once the traffic is captured, the generated logical layout can be grouped in various ways in order to obtain an in-depth understanding of the flow of traffic and the protocols being utilized. Analysis on ICS/SCADA traffic can be done by grouping as:
· ICS Protocol
By grouping traffic in various ways as mentioned above, a great deal of awareness can be achieved. GrassMarlin consists of a GeoIP database, various fingerprints, and vendor IDs. It displays a country’s flag if the traffic is reaching out to any public IP in the USA or to any other country in the world. The Vendor ID identifies the vendor of the network interface cards on the devices.
For example, ICS/SCADA system misconfigurations can be detected along with a careful analysis of traffic which may provide a clue if any of the components of the ICS/SCADA system is infected with malware and is trying to communicate outside of the network where it has no business communicating.
GrassMarlin also allows the user to view all frames being transferred between two hosts on the network. By simply right-clicking on any host and then selecting the “view frames option,” you will be provided with a great deal of communication information as shown in the figure below:

A collection of sample ICS/SCADA network PCAP files are available through the following link:
Feel free to download and import the above mentioned files in GrassMarlin in order to obtain a deeper understanding of the tool and/or perhaps find a way to use it in your next testing assignment.
