Look Back at "Security Problems in the TCP/IP Protocol Suite"
Source: AT&T Labs
About fifteen years ago, the author wrote a paper on security problems in the TCP/IP protocol suite, In particular, the author focused on protocol-level issues, rather than implementation flaws. It is instructive to look back at that paper, to see where the author's focus and predictions were accurate, where he was wrong, and where dangers have yet to happen. This is a reprint of the original paper, with added commentary. The paper "Security Problems in the TCP/IP Protocol Suite" was originally published in Computer Communication Review, Vol. 19, No. 2, in April, 1989.
