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:

# 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
nmap -oA scan 192.168.1.100          # All formats

Masscan

High-speed port scanning for large networks:

# Basic scanning
masscan -p80 192.168.1.0/24 --rate=1000
masscan -p80,443,8080 192.168.1.0/24 --rate=10000

# Full port range
masscan -p0-65535 192.168.1.0/24 --rate=5000

# Large-scale scanning
masscan 0.0.0.0/0 -p443 --rate=100000 --excludefile exclude.txt

# Output formats
masscan -p80 192.168.1.0/24 -oG results.gnmap
masscan -p80 192.168.1.0/24 -oJ results.json
masscan -p80 192.168.1.0/24 -oX results.xml

# Banner grabbing
masscan -p80 192.168.1.0/24 --banners

Phase 2: Vulnerability Scanning Tools

Nessus

Enterprise-grade vulnerability assessment:

# Start Nessus service
sudo systemctl start nessusd

# Access web interface
# https://localhost:8834

# Command-line (nessuscli)
nessuscli scan --create --name "Internal Scan" --targets 192.168.1.0/24
nessuscli scan --list
nessuscli scan --launch <scan_id>

sudo gvm-setup

# Start services
sudo gvm-start

# Access web interface (Greenbone Security Assistant)
# https://localhost:9392

  <hosts>192.168.1.0/24</hosts>
</create_target>'

Phase 3: Web Application Scanning Tools

Burp Suite

Comprehensive web application testing:

# Proxy configuration
1. Set browser proxy to 127.0.0.1:8080
2. Import Burp CA certificate for HTTPS
3. Add target to scope

# Key modules:
- Proxy: Intercept and modify requests
- Spider: Crawl web applications
- Scanner: Automated vulnerability detection
- Intruder: Automated attacks (fuzzing, brute-force)
- Repeater: Manual request manipulation
- Decoder: Encode/decode data
- Comparer: Compare responses

Core testing workflow:

1. Configure proxy and scope
2. Spider the application
3. Analyze sitemap
4. R
