Not really. You'll need a variety of resources:
A reference for port numbers:
http://www.iana.org/numbers.html
References about port filtering and firewall configuration:
"Building Internet Firewalls" O'Reilly
Chapman & Zwicky
References about vulnerabilities:
CERT, CIAC, etc.
References about optimally configuring those services whose
vulnerabilities you accept:
Individual installation manuals
Various NT, Unix, and application specific web sites that give
"best practices" suggestions. Some are listed at:
