sshdfilter automatically blocks ssh brute force attacks by reading sshd log output in real time and adding iptables rules based on authentication failures. Block rules are created by logging on with an invalid user name, or wrongly guessing the password for an existing account. Block rules are removed after a week to maintain a small list of blocks. It also comes with a LogWatch filter.

It provides a new packet filtering framework, a new userspace utility, and a compatibility layer for {ip,ip6}tables. nftables is built upon the building blocks of the Netfilter infrastructure such as the existing hooks, the connection tracking system, the userspace queueing component, and the logging subsystem.

fwknop implements an authorization scheme called Single Packet Authorization that requires only a single encrypted packet to communicate various pieces of information, including desired access through an iptables, ipfw, or pf firewall 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 much more difficult. The authorization server works by passively monitoring authorization packets via libpcap. Also supported is a robust port knocking implementation based around iptables log messages.

sslh accepts connections in HTTP, HTTPS, SSH, OpenVPN, tinc, XMPP, or any other protocol that can be tested using a regular expression, on the same port. This makes it possible to connect to any of these servers on port 443 (e.g. from inside corporate firewalls, which almost never block port 443) while still serving HTTPS on that port. sslh supports IPv6, privilege dropping, transparent proxying, and much more.
