CTMp network sensors The first six Google hits for this phrase, relate to Fox-IT being hit. Can anyone share some details on these sensors, given they are described as being critical to the response?

Some of the results I find for CTMP are Continuous Time Markov Processes. Here is a slide deck with poor kerning[0]. From an interesting slide: Numerical solution of implicitly encoded CTMCs If R is stored as a sparse matrix of columns, a Jacobi or GaussSeidel iteration has the cost of a vector-matrix multiplication, O(n(R)) If R is stored using implicit techniques (Kronecker algebra or decision diagrams), memory is greatly reduced but runtime can increase. E.g., using Shuffle to compute the effect of v, (pi)^(old) . (operator)(L<k<1) R(k,v1), is slower than Sparse multiplication if the R(k,v) matrices are very sparse. This research paper describes tracking cattle with a wireless sensor network[1]. --- Or this could be Cisco Technology Migration Program[2]. They could have some sort of network probe to identify "upgrade-ready" products, which could be leveraged for other purposes. --- [0] http://www.cs.ucr.edu/~cshelton/talks/ctmp-tut.pdf http://www.cs.ucr.edu/~cshelton/talks/ctmp-tut.pdf [1] https://www.researchgate.net/publication/271419298_Cattle_monitoring_system_using_wireless_sensor_network_in_order_to_prevent_cattle_rustling https://www.researchgate.net/publication/271419298_Cattle_mo...

  Dude... CTMP means Cyber Threat Management System and it's a producy developed by Fox-IT as monitoring solution.

I'm going from (a not very good) memory but I wanna say it's something like "<something> traffic monitoring probe". Basically, they do full packet captures of all network traffic and retain it for a certain period of time so that it can be reviewed later (such as when something like this happens).

I work for Fox-IT (but don't speak for Fox-IT here). CTMp network sensors are servers storing and filtering network traffic, and generating alerts. We use these sensors for our own monitoring services, and provide these sensors to others as part of the Cyber Threat Management platform (software to run your own Security Operations Center, with greater or lesser involvement of Fox-IT experts).
