North American Network Operators Group Date Prev | Date Next | Date Index | Thread Index | Author Index | Historical Operational impact of filtering SMB/NETBIOS traffic?
Due to an increasing number of intrusions into windows-based machines through unprotected shares, I've started filtering both incoming and outgoing traffic for our customers on ports 138/139. So far this has caught a fair amount of traffic coming from customers, but none have called to complain about a lack of connectivity. Because this traffic is IP traffic, I wanted to ask others on this list how they treat SMB traffic on their backbones? Thanks -Scott
