Recent high profile automotive hacks have highlighted security weaknesses in some CAN based systems. The NMEA Organisation have responded to this threat by establishing a Cyber Security Working Group to identify and mitigate the risks of maritime attacks. N2K Protect is the World's first cyber security product focused on NMEA 2000 to be developed as part of this NMEA initiative.\u003c\/p\u003e \u003cp\u003eN2K Protect is a self-contained bus powered unobtrusive black box that receives and analyses all NMEA 2000 network data. It has three key functions:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eTest and validate the NMEA 2000 network during installation\u003c\/li\u003e \u003cli\u003eTools for NMEA 2000 configuration and network monitoring\/analysis\u003c\/li\u003e \u003cli\u003eOn going 24\/7 monitoring and protection for the life of the vessel\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eInstallation Tests and Canshot\u003c\/h3\u003e \u003cp\u003eN2K Protect carries out the following device certification network topography and general tests:\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCertified Devices -\u003c\/strong\u003e This test interrogates all devices on the network and checks if they are listed in the NMEA 2000 Certified Product database. Un-Certified devices will be identified as they represent a possible cause of network errors and interoperability issues. The identified devices can continue to be used on the network but it is recommended that special care is taken to ensure that they are operating correctly and not causing network issues.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eName Verification -\u003c\/strong\u003e This test scans the NMEA Name (64 bit binary number) of each device on the network and will report any non-standard or rogue NMEA names that might indicate a malicious device. Any devices reported should be immediately investigated and removed from the network.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eGateway Validation - \u003c\/strong\u003eGateways are potentially a weak point in an NMEA 2000 network and can allow hackers to inject malicious data or control a network. For this reason N2K Protect can identify and validate any NMEA 2000 Gateway in the system.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDuplicate Device Instances - \u003c\/strong\u003eMultiple devices on the network sharing the same class and function codes and the same device instance can cause issues with data source identification and could be used to inject spoof data on to the network. This test will identify any duplications and the Instance Configuration Tool can be used to give a duplicate device a unique device instance.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDuplicate PGNs - \u003c\/strong\u003eMultiple devices outputting duplicate PGNs can cause issues with data source selection and result in some devices showing wrong or no data. This test will identify any duplicate PGNs and the Commanded Address Change Tool can be used to change a device's CAN address reducing or increasing its priority.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eData Sources - \u003c\/strong\u003eThis test in conjunction with the other Network Topography tests can be used to identify which devices will be automatically selected as the primary data source for GNSS depth wind boat speed and heading. Based on the PGNs they output and their CAN Address N2K Protect will identify the devices that are the primary data sources and the Commanded Address Change Tool can be used to change which device is the primary data source.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDevices Outputting \"No Data\" - \u003c\/strong\u003eThis test checks all of the devices that are outputting navigational PGNs with \"No Data\" in the key field i.e. transmitting a Depth PGN with the depth field showing \"No Data\" If a higher priority device is outputting \"ËœNo Data' it can result in the data from the device you want to use not being displayed.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eProduct Firmware Audit - \u003c\/strong\u003eThis test will query every device on the network and create a simple list of the Firmware Version reported in each device's Product Info PGN. This is useful for checking that all devices on the network are fully up to date or if a firmware update has been done and caused problems since the current CANshot was taken.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eTotal LEN - \u003c\/strong\u003eThis test queries the LEN value of all devices on the network and calculates the total LEN value for the network. This can be useful in ensuring the network is properly designed and constructed and will not suffer from voltage drops or data corruption.\u003c\/p\u003e \u003cp\u003eOnce the installation tests are complete and the installer is happy with network performance the CANshot option is run. This \"snapshots\" the network and stores the results internally. This report can also be saved and printed. N2K Protect then enters 24\/7 monitor mode and will alert audibly and also store alerts in an event log for analysis. If connected to a Digital Yacht 4GX or 5GX system optional SMS alerts can be enabled for remote monitoring.\u003c\/p\u003e \u003ch3\u003e24\/7 Monitoring\u003c\/h3\u003e \u003cp\u003eN2K Protect continuously monitors your NMEA 2000 network. A new device change to existing device or strange network behaviour will trigger N2K Protect to take action. Depending on threat level this could be a pop-up warning transmission of an NMEA 2000 Alert PGN sounding its internal buzzer or even an SMS message to designated mobile phone via our 4Gx\/5GX systems. The last 16 events are stored in a Network Events Log.\u003c\/p\u003e \u003ch3\u003eConfiguration and Data Tools\u003c\/h3\u003e \u003cp\u003eN2K Protect also features the following configuration and data analysis tools:\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eConfiguration Info Programming -\u003c\/strong\u003e Allows you to change the Configuration Info text in any of the devices. Not all devices support this function but it has now been mandated in the N2K specification so will become increasingly important.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eInstance Configuration - \u003c\/strong\u003eChanges the Device Instance of an N2K device Not all devices support this but most engine gateways and devices that use instances do.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCommanded Address Change - \u003c\/strong\u003eAllows you to change the address of a device and all devices should support this to meet certification standards\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNetwork Device List - \u003c\/strong\u003eShows a list of devices on the network with address manufacturer name CAN name class and function\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003ePGN List - \u003c\/strong\u003eShows time stamped PGN number and source description with drill down data\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eData Logging - \u003c\/strong\u003eCreate and save a full data log of raw binary data\u003c\/p\u003e","brand":"Digital Yacht","offers":[{"title":"Default","offer_id":59815047102798,"sku":"144-DIGN2KPROT","price":250.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1043\/8914\/9006\/files\/144-dign2kprot_1.jpg?v=1780679615","url":"https:\/\/southernyachtelectrics.store\/products\/digital-yacht-n2k-protect-nmea-2000-cyber-security-system","provider":"Southern Yacht Electrics","version":"1.0","type":"link"}
