answer:An Intrusion Prevention System (IPS) is a security solution that is designed to prevent and block unauthorized access to a network or system by actively detecting and responding to potential security threats. IPS sits in the network path and actively scans and analyzes network traffic, and is capable of blocking malicious packets or traffic in real-time. IPS systems work by using a set of predefined rules and signatures to analyze network traffic and packet payloads. When a potential attack is detected, the IPS can take action to block the traffic, typically by blocking IP addresses, blocking ports, or dropping packets. IPS can also be configured to alert security administrators when a security breach is detected. Unlike an IDS, which alerts security administrators but does not actively block the traffic, IPS can take proactive measures to block malicious traffic before it enters the network. IPS can prevent various attacks, including DDoS attacks, malware, and zero-day exploits. However, IPS is not foolproof and can generate false positives or false negatives. It is important to regularly update the IPS with the latest threat intelligence and perform regular testing to ensure that the system is functioning as expected. IPS should be used in conjunction with other security measures such as firewalls, antivirus software, and secure authentication controls to provide holistic security to the network and systems.
