Most of us use computers in a network; however, do we know how information is transmitted and received by computers on a network? Through ports! You can send data to any computer on the network through knowledge of its IP address. However, for the receiving computer to understand which program to use to be able to access the data, it should include the IP address as well as the port number. Let’s know more about port 445 and port 88.
Port 445 is used by MS Windows 2000, MS Windows XP, and MS Windows Server 2003 for service message block (SMB). The SMB protocol is mainly employed for file sharing on MS Windows XP, 2000, 2003, and ME. Different operating systems use port 445 to provide security options at the highest level. For an inbound traffic, port 445 scans the computer for any of the shared files that outsiders try to bring in to the system. Any malicious applications that can spoil the functioning of the computer are blocked by this port number.
Exclusively for Kerberos, port 88 is used for implementing administrative security. This port requires log-in information that should match exactly with the configured pass settings to the administrative sector. Therefore, port 88 works as a guard that requires proper access information to go to that sector. In case the exact required login information is not provided, this port blocks access to this sector. Port 88 has also been known to be functional just for certain versions. This is mainly because of the different versions of the software.
