Name        : fwknop
Product     : Fedora 22
Version     : 2.6.5
Release     : 2.fc22
URL         : http://www.cipherdyne.org/fwknop/
Summary     : A Single Packet Authorization (SPA) implementation
Description :
fwknop implements an authorization scheme known as Single Packet
Authorization (SPA) that requires only a single encrypted packet to
communicate various pieces of information including desired access through an
iptables policy and/or specific commands to execute on the target system.
The main application of this program is to protect services such as SSH with
an additional layer of security in order to make the exploitation of
vulnerabilities (both 0-day and unpatched code) much more difficult.  The
authorization server passively monitors authorization packets via libpcap and
hence there is no "server" to which to connect in the traditional sense.  Any
service protected by fwknop is inaccessible (by using iptables to
intercept packets within the kernel) before authenticating; anyone scanning for
the service will not be able to detect that it is even listening.  This
authorization scheme offers many advantages over port knocking, include being
non-replayable, much more data can be communicated, and the scheme cannot be
broken by simply connecting to extraneous ports on the server in an effort to
break knock sequences.  The authorization packets can easily be spoofed as
well, and this makes it possible to make it appear as though, say,
www.yahoo.com is trying to authenticate to a target system but in reality the
actual connection will come from a seemingly unrelated IP. Although the
default data collection method is to use libpcap to sniff packets off the
wire, fwknop can also read packets out of a file that is written by the
iptables ulogd pcap writer or by a separate sniffer process.
