H3C Technologies H3C SecBlade IPS Cards - Manual (Page 3)

Preface
H3C IPS products are new-generation intrusion prevention devices developed by H3C for enterprise
users, industry users, and Telecom users. They are one of the most crucial products in the intelligent
Safe Pervasive Network (iSPN) of H3C IToIP architecture.
An IPS device can be deployed in the inline mode on the critical path of a network to perform detailed
inspection of Layer 2-7 traffic passing through the path, and thus to precisely identify, block, and control
various types of network attacks or flood attacks in real time.
An IPS device can also be connected to a network in the bypass mode. In that case, the IPS device is
similar to the intrusion detection system (IDS) device in functions. It can capture packets by receiving
mirrored traffic and detecting copied packets, and execute security actions indirectly through response
packets, thus protecting the network.
Moreover, IPS devices can provide powerful and realistic bandwidth management and URL filtering
functions.
H3C IPS products involve the complete series of high end-to-low end IPSs, and provide box-type
devices and card-type IPS devices. For more information about IPS models, see H3C IPS Series
Products at the H3C website.
