SpyLog alternatives

  • SSHGuard

  • SSHGuard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. SSHGuard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng, metalog, multilog, raw messages), and detects attacks for many services out of the box, including SSH, several ftpds, and dovecot. It can operate all the major firewalling systems, and features support for IPv6, whitelisting, suspension, and log message authentication. ยป

  • Fail2ban

  • Fail2ban scans log files (e.g. /var/log/apache/error_log) and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc. Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time, although any arbitrary other action (e.g. sending an email) could also be configured. Out of the box Fail2Ban comes with filters for various services (apache, courier, ssh, etc).

  • Denyhosts

  • The idea of denying access to SSH servers is nothing new and I was inspired by many other scripts that I discovered. However, none of them did things the way I envisioned them to. Also, they were all shell scripts which do not offer the elegance of Python.

  • tallow

  • Tallow is a fail2ban/lard replacement that uses systemd's native journal API to scan for attempted ssh logins, and issues temporary IP bans for clients that violate certain login patterns.

  • IPQ BDB

  • IPQ BDB filtering is done by a user space netfilter daemon that issues verdicts after looking up the IP address in a Berkeley DB. The fuzzy blocking model, freely inspired by STOCKADE, is designed to block non-distributed dictionary attacks and mitigate spam.

  • RdpGuard

  • RdpGuard allows you to protect your Remote Desktop (RDP) from brute-force attacks by blocking attacker's IP address. Fail2Ban for Windows.

  • IPBan

  • A FREE and open source application that allows banning ip addresses from failed terminal services or SQL server logins out of the box. Other types of banning are easily added via an application configuration file.

  • EvlWatcher

  • Protected against RDP-Brute forcers. It installs a service which scans the event log for anomalies every 30 seconds (by default).When the service finds out that someone is taunting your server with RDP-login attempts, it adds the remote IP to a generic rule in the windows firewall which locks out the attacker. After 2 hours (default), the ban will be lifted, i.e. the IP will be removed from the rule.

  • HeatShield

  • HeatShield is a network firewall management service for Linux servers. A firewall configured by HeatShield prevents unauthorized access to services running on your servers, such as SSH and MySQL. Using HeatShield, you can easily restrict access to these services so that only IP addresses you trust are allowed to communicate with your servers.
