Abstract: Methods and systems for detecting a potential compromise of cyber security in an industrial network are disclosed. These methods and systems comprise elements of hardware and software for generating and analyzing vectors indicative of network behavioral states to establish thresholds for anomalous behavior in the industrial network.

Abstract: A combination tape measure and marker is provided. The combination tape measure and marker includes a measuring tape housing having a lateral portion, a lower portion, and a front portion. A track is connected to the lateral portion of the measuring tape housing. An arm is slidably disposed within the track. A tension member having an arcuate shape can slide the arm towards the lower portion when depressed. A cartridge is integrally attached to the front portion of the measuring tape housing. The arm extends through the cartridge. A marker is removably secured within the cartridge and is operationally attached to the arm. A spring is housed in the cartridge and provides a retracted and extended position for the marker. The marker is movably separately and independently from the measuring tape housing by selectively depressing the arm.

Abstract: Methods and systems for detecting a potential compromise of cyber security in an industrial network are disclosed. These methods and systems comprise elements of hardware and software for establishing a baseline of site-acceptable network behavior comprising a list of network states and transition probabilities, wherein a transition probability denotes an estimated probability of a first network state being followed temporally by a second network state during normal network operation; establishing a threshold representing tile probability below which a sequence of network states is anomalous; determining a probability for the occurrence of a sequence of network states as obtained from a particular stream of packets, according to the baseline of site-acceptable network behavior; and, taking protective action according to whether the determined probability is below the established threshold.

Abstract: Disclosed is a system and method for detecting anomalous behavior in Industrial Control Networks. The system first operates in a learning phase to learn various behaviors, and then in a protection phase to analyze packets to identify anomalous network events, and, for example, raise an alert.

Abstract: A combination tape measure and marker is provided. The combination tape measure and marker includes a measuring tape housing having a top portion and a front portion. A lever arm is connected to the top portion of the measuring tape housing. A cartridge is integrally attached to the front portion of the measuring tape housing. The lever arm extends through the cartridge. A marker is removably secured within the cartridge and is operationally attached to the lever arm. A spring is housed in the cartridge and provides a retracted and extended position for the marker. The marker is movable separately and independently from the measuring tape housing by selectively depressing the lever arm to lock the marker in an extended position to mark a surface.
