## Projektgeschichte und Nutzung

SSHGuard is a small intrusion-prevention utility that watches system logs for brute-force attacks and blocks repeat offenders through a firewall backend. It became package-manager material because it gives Unix administrators a lightweight alternative to heavier log-monitoring stacks.

### Projektgeschichte

The official manual and README describe SSHGuard as a tool that aggregates logs and blocks attackers using backends such as pf, ipfw, firewalld, iptables, ipset, nftables, IPFILTER, and hosts.allow. The manual copyright dates begin in 2007, and the current manual version is 2.5.1.

### Adoptionsgeschichte

SSHGuard's official site emphasizes portability and small size, describing it as small C and Bourne shell code with support for many log sources and firewall systems. The input package-manager facts show it available across Homebrew, Debian, Ubuntu, Fedora, Arch, Alpine, Nix, MacPorts, and openSUSE ecosystems.

### Wie es verwendet wird

Operators configure `sshguard.conf`, choose a backend, and feed SSHGuard logs through files, syslog-style services, systemd journal, or macOS log streaming. Attackers are blocked after their score exceeds a threshold and can be temporarily blocked, permanently blacklisted, or whitelisted through explicit addresses or a whitelist file.

### Warum Paket-Nerds sich dafür interessieren

Package nerds care because SSHGuard is pure Unix plumbing: logs in, firewall commands out, minimal daemon surface. It is a good example of security tooling whose packaging value lies in service files, default config paths, backend selection, and integration with each operating system's logging and firewall conventions.

### Zeitleiste

- 2007: Official sshguard(8) manual copyright period begins.
- 2024: Official website footer and current site generation reflect active project site maintenance.
- 2025: Official manual pages list version 2.5.1 and date January 1, 2025.

### Related projects

- SSHGuard is related to OpenSSH server logs, syslog, systemd journal, pf, ipfw, firewalld, iptables, ipset, nftables, IPFILTER, and other brute-force blocking tools.
