## What it does

The skill covers Nmap and Masscan for finding hosts and open ports, Nessus and OpenVAS for vulnerability assessment, and Burp Suite, OWASP ZAP, and Nikto for web application testing. Command examples show scanning and saving results in several formats. Wireless scanning and compliance checks are covered too.

A Linux system, network access to the targets, and basic TCP/IP, port, and protocol knowledge are prerequisites. Scan only systems you are authorized to test; running checks without permission is not appropriate. The guide also walks through setting up Burp Suite as a proxy and running ZAP from the command line.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill scanning-tools -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/scanning-tools/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/scanning-tools/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill scanning-tools -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/scanning-tools/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**

npx skills add zebbern/claude-code-guide --skill scanning-tools -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/scanning-tools/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install zebbern/claude-code-guide scanning-tools
```

2. **Manually: put the files in place**
- File: `.github/skills/scanning-tools/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill scanning-tools -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/zebbern/claude-code-guide --path skills/scanning-tools
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/scanning-tools/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill scanning-tools -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/zebbern/claude-code-guide/tree/HEAD/skills/scanning-tools/SKILL.md

## When to use it
- discover active hosts and open network ports
- choose a tool for vulnerability assessment
- test a web application with a security scanner
- save scan results as a report
- check systems against CIS or PCI-DSS requirements

## Example prompts
- Scan my authorized network for active hosts and open ports with Nmap.
- Show me how to test my web app with OWASP ZAP and save an HTML report.
- Compare Nessus and OpenVAS for assessing vulnerabilities on my system.

# Security Scanning Tools

## Purpose

Master essential security scanning tools for network discovery, vulnerability assessment, web application testing, wireless security, and compliance validation. This skill covers tool selection, configuration, and practical usage across different scanning categories.

## Prerequisites

### Required Environment
- Linux-based system (Kali Linux recommended)
- Network access to target systems
- Proper authorization for scanning activities

### Required Knowledge
- Basic networking concepts (TCP/IP, ports, protocols)
- Understanding of common vulnerabilities
- Familiarity with command-line interfaces

## Outputs and Deliverables

1. **Network Discovery Reports** - Identified hosts, ports, and services
2. **Vulnerability Assessment Reports** - CVEs, misconfigurations, risk ratings
3. **Web Application Security Reports** - OWASP Top 10 findings
4. **Compliance Reports** - CIS benchmarks, PCI-DSS, HIPAA checks

## Core Workflow

### Phase 1: Network Scanning Tools

#### Nmap (Network Mapper)

Primary tool for network discovery and security auditing:

```bash
# Host discovery
nmap -sn 192.168.1.0/24              # Ping scan (no port scan)
nmap -sL 192.168.1.0/24              # List scan (DNS resolution)
nmap -Pn 192.168.1.100               # Skip host discovery

# Port scanning techniques
nmap -sS 192.168.1.100               # TCP SYN scan (stealth)
nmap -sT 192.168.1.100               # TCP connect scan
nmap -sU 192.168.1.100               # UDP scan
nmap -sA 192.168.1.100               # ACK scan (firewall detection)

# Port specification
nmap -p 80,443 192.168.1.100         # Specific ports
nmap -p- 192.168.1.100               # All 65535 ports
nmap -p 1-1000 192.168.1.100         # Port range
nmap --top-ports 100 192.168.1.100   # Top 100 common ports

# Service and OS detection
nmap -sV 192.168.1.100               # Service version detection
nmap -O 192.168.1.100                # OS detection
nmap -A 192.168.1.100                # Aggressive (OS, version, scripts)

# Timing and performance
nmap -T0 192.168.1.100               # Paranoid (slowest, IDS evasion)
nmap -T4 192.168.1.100               # Aggressive (faster)
nmap -T5 192.168.1.100               # Insane (fastest)

# NSE Scripts
nmap --script=vuln 192.168.1.100     # Vulnerability scripts
nmap --script=http-enum 192.168.1.100  # Web enumeration
nmap --script=smb-vuln* 192.168.1.100  # SMB vulnerabilities
nmap --script=default 192.168.1.100  # Default script set

# Output formats
nmap -oN scan.txt 192.168.1.100      # Normal output
nmap -oX scan.xml 192.168.1.100      # XML output
nmap -oG scan.gnmap 192.168.1.100    # Grepable output
