DenyHosts
DenyHosts is a log-based intrusion prevention security tool for SSH servers written in Python. It is intended to prevent brute-force attacks on SSH servers by monitoring invalid login attempts in the authentication log and blocking the originating IP addresses. DenyHosts is developed by Phil Schwartz, who is also the developer of Kodos Python Regular Expression Debugger. ==Operation== DenyHosts checks the end of the authentication log for recent failed login attempts. It records information about their originating IP addresses and compares the number of invalid attempts to a user-specified threshold. If there have been too many invalid attempts it assumes a dictionary attack is occurring and prevents the IP address from making any further attempts by adding it to /etc/hosts.deny on the server. DenyHosts 2.0 and above support centralized synchronization, so that repeat offenders are blocked from many computers. The site (denyhosts.net ) gathers statistics from computers running the software. DenyHosts is restricted to connections using IPv4. It does not work with IPv6. DenyHosts may be run manually, as a daemon, or as a cron job.
