Datagram Congestion Control Protocol (DCCP) provides a connection-oriented unreliable transport layer. In Red Hat Enterprise Linux 8 (RHEL 8), situations may arise where disabling this protocol is necessary. This action prevents the system from utilizing DCCP for network communications. This can be achieved through kernel module management.
Disabling unused network protocols can contribute to a reduced attack surface and improved system security. By removing or preventing the loading of the DCCP kernel module, administrators can minimize potential vulnerabilities associated with the protocol. Furthermore, removing unnecessary modules can free up system resources, although the impact in this specific case is generally minimal.
