Nemesis: a unique managed cyber security solution

Nemesis is a unique managed cyber security solution designed for the Maritime Industry. It is an in-house developed Security Information & Event Management (SIEM) System, tailor-made for vessels.

Easy to deploy and extremely cost effective, Nemesis was designed from scratch to address all inherent problems of providing information security on a vessel.
Depending on a vessel’s available infrastructure Nemesis can be deployed on a VM or delivered ready to install as a lightweight preconfigured bundle of hardware and software. These specially designed devices act as nemesis delivery mechanisms, are installed in each vessel, collecting valuable security-related data and intelligence from the vessel’s IT and OT systems.

Cybersecurity designed specifically for the maritime sector

Nemesis has been designed to be compatible with virtually any onboard equipment, modern and legacy included. Contrary to a conventional SIEM and in order to keep satellite communications costs low, Nemesis doesn’t transfer all logs to Aspida’s 24/7/365 Security Operations Center.
Instead logs are collected and preliminarily analysed onboard, escalating detection and response depending on severity, and alerting our experienced Cyber Security Analysts as well as predefined personnel from the ship managing company only when required.

The Nemesis modules onboard communicate with Aspida’s state-of-the art SOC using the vessel’s satellite communication. Currently in production stage protecting vessels and well after prototyping Nemesis is an unprecedented, inexpensive and straightforward response to the growing cyber threat

 

A Complete Solution

Nemesis is a Business Solution which is a complete vessel’s cyber threat detection mechanism, able to detect intrusions in real time.

We manage to identify threats known to the Global Security Community via our Threat Intelligence module. A client portal is also provided accompanied by our Alerting System capable to inform all related personnel (DPA, IT Department, Security Analysts, CISO) with critical events occurred in the network real-time.

Data acquisition is achieved via our Nemesis endpoints which are installed individually on every vessel we monitor. A Nemesis endpoint instance/device has the ability to correlate and report back data collected from Servers, Bridge Computers, managed Network Devices, SCADAs/PLCs, and Simple End User PCs in near real time. Nemesis was developed and customized bearing in mind the operational limitations of the maritime sectors and the inherent needs of a vessel:
Installing a conventional SIEM on a vessel does not fit the purpose as it would require additional and constant bandwidth- Connectivity can not be guaranteed on a vessel while pushing logs constantly to a shore facility can significantly increase communication costs. Furthermore a conventional SIEM solution would need to be installed and commissioned onboard adding on the costs and complexities of a deployment.

 

Nemesis addresses all the above limitations.

By transferring part of our threat intelligence and log correlation onboard the vessel we can have constant monitoring against cyber threats while significantly reducing the satellite connectivity bills.
By deploying the solution either as a preconfigured VM or a small lightweight device we can deploy digitally or physically with the smallest cost and delay.
Moreover the system monitors IT and OT infrastructure even when satellite connectivity is down.
In the case of short or long periods of disconnection, Nemesis can preserve all the logs and potential alerts and transmit it back to Aspida without losing a single message when connectivity resumes.
