Internet Service Providers: The Little Man's Firewall
Anonymous Reader writes "The fast spread of network worms and other malware has forced Internet Service Providers (ISPs into implementing packet filtering. In some cases, this is the only way to keep the network operating, but it has become common to block certain ports permanently even after the threat diminishes. We argue in favor of limited, long term port blocking. This paper does not intend to present a balanced argument. It intends to provide a starting point for a larger discussion of the issue."
