- IPS vs. IDS: Similar on the Surface, Polar Opposites Underneath
- A common notion is that an Intrusion Prevention System IPS is nothing more than an Intrusion Detection System IDS deployed in-line with blocking capabilities. Although IPS and IDS both examine traffic looking for attacks, there are critical differences. Learn why that notion is incorrect and the many critical differences in...

- Analysis of Different Architectures of Neural Networks for Application in Intrusion Detection Systems
- Usually, Intrusion Detection Systems IDS work using two methods of identification of attacks: by signatures that are specific defined elements of the network traffic possible to identification and by anomalies being some deviations form of the network behavior assumed as normal. In the both cases one must pre-define the form...
