Why is it important to utilize IPS on non-standard ports?

Utilizing IPS (Intrusion Prevention System) on non-standard ports is crucial because attackers frequently target common applications that operate on these ports. While standard ports like 80 (HTTP) and 443 (HTTPS) are monitored more closely and have well-defined security mechanisms, non-standard ports can provide an avenue for malicious activities since they may be overlooked.

Attackers often exploit vulnerabilities in applications that run on non-standard ports, as they assume that security systems will focus more on standard ports, leaving these alternatives exposed. By monitoring non-standard ports with IPS, organizations can detect and prevent potential attacks that may use these less scrutinized pathways.

This proactive approach enhances overall security posture by ensuring that all traffic, regardless of the port it traverses, is appropriately inspected for malicious activity. It acknowledges that vulnerabilities can exist across all avenues of network communication and emphasizes the importance of comprehensive monitoring.
