The phrase "active countermeasures" is correct and usable in written English.
It can be used in contexts related to security, defense, or technology, referring to proactive strategies or actions taken to counteract threats or attacks.
Example: "The cybersecurity team implemented active countermeasures to protect the network from potential breaches."
Alternatives: "proactive defenses" or "defensive actions".
The integrated system was a direct combination of the passive and active countermeasures.
The aim of this study was to investigate the potential pedestrian head injury reduction from hypothetical passive and active countermeasures compared to an integrated system.
Ongoing work includes optimizing the performance of NNIDS, developing strategies for sustainable operation of the NNIDS under attacks through adaptation and active countermeasures, studying algorithms for distributed and collaborative intrusion detection, and further developing the analytical models for buffer and processor allocation.
The active countermeasure was an autonomous braking system, which was activated one second prior to impact if the pedestrian was visible to a forward-looking sensor.
The integrated system resulted in 50%95%5% confidence interval: 30 70%) greater effectiveness than the active countermeasure in reducing the number of pedestrians sustaining severe (AIS3+) head injuries, and 90%9595% CI: 50 150%) greater effectiveness than the passive countermeasure.
Integrated systems of passive and active pedestrian countermeasures offer a considerably increased potential for head injury reduction compared to either of the two systems alone.
We review the different types of active and passive countermeasures available, categorizing them and assessing whether or not they are suitable for Critical Infrastructure Protection (CIP).
One type of countermeasure, active safety systems, requires a deep understanding of driver behaviour to be effective without being annoying.
The first three approaches (prevention, preemption, and deterrence) are passive measures to guard against attacks, and the latter three (deflection, detection, and countermeasures) are active measures to protect elements in a system.
Management of microclimate by controlling relative humidity, eradicating biofilms by physical and chemical strategies and keeping them in check by using non-photosynthetic active lighting is a countermeasure that should be further investigated.
But they argued that such costs were not inevitable and that, in some countries, countermeasures such as active labour market schemes had softened the blow from cuts.
