Define scope and objectives - Obtain proper authorization - Select appropriate tools 2. **Discovery** - Host discovery (Nmap ping sweep) - Port scanning - Service enumeration 3. **Vulnerability Assessment** - Automated scanning (Nessus/OpenVAS) - Web application scanning (Burp/ZAP) - Manual verification 4. **Analysis** - Correlate findings - Eliminate false positives - Prioritize by severity 5. **Reporting** - Document findings - Provide remediation guidance - Executive summary ### Phase 9: Tool Selection Guide Choose the right tool for each scenario: | Scenario | Recommended Tools | |----------|-------------------| | Network Discovery | Nmap, Masscan | | Vulnerability Assessment | Nessus, OpenVAS | | Web App Testing | Burp Suite, ZAP, Nikto | | Wireless Security | Aircrack-ng, Kismet | | Malware Detection | ClamAV, YARA | | Cloud Security | Prowler, ScoutSuite | | Compliance | Lynis, OpenSCAP | | Protocol Analysis | Wireshark, tcpdump | ### Phase 10: Reporting and Documentation Generate professional reports: ```bash # Nmap XML to HTML xsltproc nmap-output.xml -o report.html # OpenVAS report export gvm-cli socket --xml '' # Combine multiple scan results # Use tools like Faraday, Dradis, or custom scripts # Executive summary template: # 1. Scope and methodology # 2. Key findings summary # 3. Risk distribution chart # 4. Critical vulnerabilities # 5. Remediation recommendations # 6. Detailed technical findings ``` ## Quick Reference ### Nmap Cheat Sheet | Scan Type | Command | |-----------|---------| | Ping Scan | `nmap -sn ` | | Quick Scan | `nmap -T4 -F ` | | Full Scan | `nmap -p- ` | | Service Scan | `nmap -sV ` | | OS Detection | `nmap -O ` | | Aggressive | `nmap -A ` | | Vuln Scripts | `nmap --script=vuln ` | | Stealth Scan | `nmap -sS -T2 ` | ### Common Ports Reference | Port | Service | |------|---------| | 21 | FTP | | 22 | SSH | | 23 | Telnet | | 25 | SMTP | | 53 | DNS | | 80 | HTTP | | 443 | HTTPS | | 445 | SMB | | 3306 | MySQL | | 3389 | RDP | ## Constraints and Limitations ### Legal Considerations - Always obtain written authorization - Respect scope boundaries - Follow responsible disclosure practices - Comply with local laws and regulations ### Technical Limitations - Some scans may trigger IDS/IPS alerts - Heavy scanning can impact network performance - False positives require manual verification - Encrypted traffic may limit analysis ### Best Practices - Start with non-intrusive scans - Gradually increase scan intensity - Document all scanning activities - Validate findings before reporting ## Troubleshooting ### Scan Not Detecting Hosts **Solutions:** 1. Try different discovery methods: `nmap -Pn` or `nmap -sn -PS/PA/PU` 2. Check firewall rules blocking ICMP 3. Use TCP SYN scan: `nmap -PS22,80,443` 4. Verify network connectivity ### Slow Scan Performance **Solutions:** 1. Increase timing: `nmap -T4` or `-T5` 2. Reduce port range: `--top-ports 100` 3. Use Masscan for initial discovery 4. Disable DNS resolution: `-n` ### Web Scanner Missing Vulnerabilities **Solutions:** 1. Authenticate to access protected areas 2. Increase crawl depth 3. Add custom injection points 4. Use multiple tools for coverage 5. Perform manual testing ## When to Use This skill is applicable to execute the workflow or actions described in the overview. --- ## AGI Framework Integration > **Adapted for [@techwavedev/agi-agent-kit](https://www.npmjs.com/package/@techwavedev/agi-agent-kit)** > Original source: [antigravity-awesome-skills](https://github.com/sickn33/antigravity-awesome-skills) ### Memory-First Protocol Cache compliance check results to avoid re-running expensive AWS API calls. Retrieve prior audit findings to track remediation progress across sessions. ```bash # Check for prior security context before starting python3 execution/memory_manager.py auto --query "prior security audit results for Scanning Tools" ``` ### Storing Results After completing work, store security decisions for future sessions: ```bash python3 execution/memory_manager.py store \ --content "Audit findings: 3 critical IAM misconfigurations found and remediated" \ --type technical --project \ --tags scanning-tools security ``` ### Multi-Agent Collaboration Share security findings with other agents so they avoid introducing vulnerabilities in their code changes. ```bash python3 execution/cross_agent_context.py store \ --agent "" \ --action "Completed security audit — 3 critical findings fixed, compliance score 94%" \ --project ``` ### Signed Audit Trail All security findings are cryptographically signed with the agent's Ed25519 identity, providing tamper-proof audit logs for compliance reporting. ### Semantic Cache for Compliance Cache compliance check results (`semantic_cache.py`) to avoid redundant AWS API calls. Cache hit at similarity >0.92 returns prior results instantly. --- Source attribution: techwavedev Original project: https://github.com/techwavedev/agi-agent-kit/blob/58f5d95434a1adc8b41a4f391d32d95311e54936/templates/skills/extended/security/scanning-tools/SKILL.md License: Apache-2.0 License information: https://www.apache.org/licenses/LICENSE-2.0 Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.
