Dashboard: https:\u002F\u002Fwazuh-dashboard:5601\n```\n\n## Key Concepts\n\n| Term | Definition |\n|------|-----------|\n| **HIDS** | Host-based Intrusion Detection System; monitors individual endpoints for malicious activity |\n| **FIM** | File Integrity Monitoring; detects unauthorized changes to files by comparing cryptographic hashes |\n| **Syscheck** | Wazuh\u002FOSSEC module for file integrity monitoring and registry monitoring |\n| **Rootcheck** | Wazuh\u002FOSSEC module for rootkit and malware detection |\n| **Active Response** | Automated defensive action triggered by HIDS alert (IP block, account disable) |\n| **CDB List** | Constant Database list used for custom lookups in Wazuh rules |\n\n## Tools & Systems\n\n- **Wazuh**: Open-source HIDS platform (fork of OSSEC) with manager, agent, and dashboard\n- **OSSEC**: Original open-source HIDS (predecessor to Wazuh)\n- **AIDE (Advanced Intrusion Detection Environment)**: Standalone file integrity checker for Linux\n- **Tripwire**: Commercial file integrity monitoring solution\n- **Samhain**: Open-source HIDS focused on file integrity and log monitoring\n\n## Common Pitfalls\n\n- **Monitoring too many directories**: FIM on entire filesystems generates excessive alerts. Focus on critical system binaries, configuration files, and web roots.\n- **Not excluding noisy files**: Frequently changing files (logs, temp, caches) generate false positive FIM alerts. Maintain exclusion lists.\n- **Ignoring baseline establishment**: First FIM scan creates a baseline. Changes detected before baseline stabilization are noise, not threats. Allow 48 hours for baseline.\n- **Active response without testing**: Auto-blocking IPs or disabling accounts can cause outages. Test active response rules in a non-production environment first.\n- **Agent enrollment failures**: Agents must successfully enroll with the manager before monitoring begins. Verify firewall rules allow port 1514 and 1515 traffic.\n","# Configuring Host-Based Intrusion Detection\n\n## When to Use\n\nUse this skill when:\n- Deploying HIDS agents (Wazuh, OSSEC, AIDE) across Windows and Linux endpoints\n- Configuring file integrity monitoring (FIM) for compliance (PCI DSS 11.5, NIST SI-7)\n- Monitoring system configuration changes, rootkit detection, and security policy violations\n- Integrating HIDS alerts with SIEM platforms for centralized monitoring\n\n**Do not use** this skill for network-based IDS (Suricata, Snort) or for EDR deployment.\n\n##

endpoints for malicious activity |\n| **FIM** | File Integrity Monitoring; detects unauthorized changes to files by comparing cryptographic hashes |\n| **Syscheck** | Wazuh\u002FOSSEC module for file integrity monitoring and registry monitoring |\n| **Rootcheck** | Wazuh\u002FOSSEC module for rootkit and malware detection |\n| **Active Response** | Automated defensive action triggered by HIDS alert (IP block, account disable) |\n| **CDB List** | Constant Database list used for custom lookups in Wazuh rules |\n\n## Tools & Systems\n\n- **Wazuh**: Open-source HIDS platform (fork of OSSEC) with manager, agent, and dashboard\n- **OSSEC**: Original open-source HIDS (predecessor to Wazuh)\n- **AIDE (Advanced Intrusion Detection Environment)**: Standalone file integrity checker for Linux\n- **Tripwire**: Commercial file integrity monitoring solution\n- **Samhain**: Open-source HIDS focused on file integrity and log monitoring\n\n## Common Pitfalls\n\n- **Monitoring too many directories**: FIM on entire filesystems generates excessive alerts. Focus on critical system binaries, configuration files, and web roots.\n- **Not excluding noisy files**: Frequently changing files (logs, temp, caches) generate false positive FIM alerts. Maintain exclusion lists.\n- **Ignoring baseline establishment**: First FIM scan creates a baseline. Changes detected before baseline stabilization are noise, not threats. Allow 48 hours for baseline.\n- **Active response without testing**: Auto-blocking IPs or disabling accounts can cause outages. Test active response rules in a non-production environment first.\n- **Agent enrollment failures**: Agents must successfully enroll with the manager before monitoring begins. Verify firewall rules allow port 1514 and 1515 traffic.\n",{"name":5,"tags":44,"author":47,"domain":29,"license":15,"version":48,"subdomain":31,"description":49},[45,32,46,30,22,33],"endpoint","Wazuh","mahipal","1.0.0","Configures host-based intrusion detection systems (HIDS) to monitor endpoint file integrity, system calls, and configuration changes for security violations.
