1, situational awareness refers to collecting, analyzing and processing all kinds of information in the network, grasping the network status and security risks in real time, and making corresponding responses and decisions, which can help administrators find abnormal behaviors, attack threats or other security problems in time and take corresponding measures to deal with them, thus improving network security.

2.IPS is an active defense security technology, which aims to prevent network attacks by monitoring network traffic and identifying and intercepting malicious traffic. IPS will detect incoming and outgoing network data streams to find known attack signatures or abnormal behaviors, and prevent the harm caused by these attacks or behaviors. Different from the traditional intrusion detection system (IDS), IPS can actively intercept and stop malicious traffic to avoid attacks damaging the network.
