Port security refers to the measures and policies implemented to safeguard computer network ports from unauthorized access, ensuring that only legitimate traffic is allowed while blocking potential threats. Effective port security plays a critical role in maintaining the integrity and confidentiality of data by controlling access points on a network, which can be targeted by malicious actors. This concept ties into hardening operating systems as it helps to minimize vulnerabilities that could be exploited through open ports.
