How can I verify if port 443 is really listening on a server? The firewall has an acl for incoming traffic allowing 443 to a specific server, but when I go to the server in IIS its being hosted on it shows port 80 only for that ip. Before I disable the rule I want to be truly sure that 443 is not listening on the server, how can I verfify? Going to <a href="https://" rel="ugc nofollow">https://</a>&nbsp;would not be an option. In the firewall this rule has very little hits which makes me unsure if it is being used (443), could the hits be that every time I go to <a href="https://url.com" rel="ugc">https://url.com</a>&nbsp;the hit increases so it is only me?<br />
<br />
Thanks.

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
