An Intrusion Prevention System (IPS) is a network security technology designed to monitor and analyze network traffic for suspicious activities. It works by identifying potential threats, such as unauthorized access or attacks, and taking action to block or prevent them in real-time. This helps protect sensitive data and maintain the integrity of computer systems. IPS solutions can be deployed as hardware or software and often complement other security measures like firewalls and antivirus programs. By continuously scanning for vulnerabilities and responding to threats, an IPS enhances overall cybersecurity and helps organizations safeguard their digital assets against cybercriminals.
