Full Analysis
- [COMMAND_EXECUTION]: The skill and its included setup script (scripts/setup-fail2ban.sh) use system-level tools such as apt, yum, and systemctl to install the fail2ban package and manage its service state.
- [PRIVILEGE_ESCALATION]: Administration tasks performed by this skill require root or sudo privileges. This is necessary for modifying system configuration files in /etc/fail2ban/ and managing firewall rules through iptables or ufw.
- [INDIRECT_PROMPT_INJECTION]: The skill is designed to monitor and process data from system logs, which are external and potentially influenced by attackers (e.g., through crafted usernames in failed SSH attempts). * Ingestion points: Log files such as /var/log/auth.log, /var/log/secure, and web server logs. * Boundary markers: Absent; logs are processed as streaming text. * Capability inventory: Full system command execution via Bash tool with sudo access. * Sanitization: While Fail2ban uses regex filters to identify patterns, these do not specifically sanitize against prompt injection payloads intended for the AI agent.
