In order to detect and block malicious activity in real time, an intrusion prevention system (IPS) actively monitors system and network traffic.IPS comprises firewall, anti-spoofing software, anti-virus/anti-malware software, and network traffic monitoring.Without human intervention, IPS is able to react to a threat. In a couple of seconds, it may initiate a physical lockdown, quarantine infected devices, and stop malicious communications.According to experts, advanced AI algorithms that run on massive amounts of data gathered at various network nodes and technological layers may be used by intrusion prevention systems. These algorithms could be dependent on additional security controls provided by stand-alone intrusion detection systems (IDS), basic firewalls, and antivirus software.There are several ways to categorize intrusion prevention systems (IPSs), including signature-based, anomaly-based, policy-based, and honeypot-based.
