# Nikto Web Server Scanner
## Overview
Nikto is an open-source web server scanner that performs comprehensive tests against web servers for multiple security issues including dangerous files, outdated software versions, and server misconfigurations. This skill covers authorized security assessments of web servers and applications.
**IMPORTANT**: Nikto generates significant traffic and is easily detected. Only use with proper written authorization on systems you own or have explicit permission to test.
## Quick Start
Basic web server scanning:
```bash
# Scan single host
nikto -h http://example.com
# Scan with SSL
nikto -h https://example.com
# Scan specific port
nikto -h example.com -p 8080
# Scan multiple ports
nikto -h example.com -p 80,443,8080
```
## Core Workflow
### Web Server Assessment Workflow
Progress:
[ ] 1. Verify authorization for web server testing
[ ] 2. Identify target web servers and ports
[ ] 3. Perform initial reconnaissance scan
[ ] 4. Run comprehensive vulnerability assessment
[ ] 5. Analyze and categorize findings
[ ] 6. Document vulnerabilities with remediation
[ ] 7. Generate and deliver security report
[ ] 8. Verify no testing artifacts remain
Work through each step systematically. Check off completed items.
### 1. Authorization Verification
**CRITICAL**: Before any web server scanning:
- Confirm written authorization from web server owner
- Verify scope includes web server vulnerability assessment
- Understand acceptable scanning windows
- Document emergency contact procedures
- Confirm no production impact restrictions
### 2. Basic Scanning
Perform basic web server scans:
```bash
# Standard scan
nikto -h http://example.com
# Scan with specific User-Agent
nikto -h http://example.com -useragent "Mozilla/5.0..."
# Scan through proxy
nikto -h http://example.com -useproxy http://proxy:8080
# Scan with authentication
nikto -h http://example.com -id username:password
# SSL/TLS scan
nikto -h https://example.com -ssl
# Force SSL even on non-standard ports
nikto -h example.com -p 8443 -ssl
```
### 3. Advanced Scanning Options
Customize scan behavior:
```bash
# Specify tuning options
nikto -h http://example.com -Tuning 123bde
# Enable all checks (very comprehensive)
nikto -h http://example.com -Tuning x
# Scan multiple hosts from file
nikto -h hosts.txt
# Limit to specific checks
nikto -h http://example.com -Plugins "apache_expect_xss"
# Update plugin database
nikto -update
# Display available plugins
nikto -list-plugins
```
**Tuning Options**:
- **0**: File Upload
- **1**: Interesting File/Seen in logs
- **2**: Misconfiguration/Default File
- **3**: Information Disclosure
- **4**: Injection (XSS/Script/HTML)
- **5**: Remote File Retrieval (Inside Web Root)
- **6**: Denial of Service
- **7**: Remote File Retrieval (Server Wide)
- **8**: Command Execution/Remote Shell
- **9**: SQL Injection
- **a**: Authentication Bypass
- **b**: Software Identification
- **c**: Remote Source Inclusion
- **d**: WebService
- **e**: Administrative Console
- **x**: Reverse Tuning (exclude specified)
### 4. Output and Reporting
Generate scan reports:
```bash
# Output to text file
nikto -h http://example.com -o results.txt
# Output to HTML report
nikto -h http://example.com -o results.html -Format html
# Output to CSV
nikto -h http://example.com -o results.csv -Format csv
# Output to XML
nikto -h http://example.com -o results.xml -Format xml
# Multiple output formats
nikto -h http://example.com -o results.txt -Format txt -o results.html -Format html
```
### 5. Performance Tuning
Optimize scan performance:
```bash
# Increase timeout (default 10 seconds)
nikto -h http://example.com -timeout 20
# Limit maximum execution time
nikto -h http://example.com -maxtime 30m
# Use specific HTTP version
nikto -h http://example.com -vhost example.com
# Follow redirects
nikto -h http://example.com -followredirects
# Disable 404 guessing
nikto -h http://example.com -no404
# Pause between tests
nikto -h http://example.com -Pause 2
```
### 6. Evasion and Stealth
Evade detection (authorized testing only):
```bash
# Use random User-Agent strings
nikto -h http://example.com -useragent random
# Inject random data in requests
nikto -h http://example.com -evasion 1
# Use IDS evasion techniques
nikto -h http://example.com -evasion 12345678
# Pause between requests
nikto -h http://example.com -Pause 5
# Use session cookies
nikto -h http://example.com -cookies "session=abc123"
```
**Evasion Techniques**:
- **1**: Random URI encoding
- **2**: Directory self-reference (/./)
- **3**: Premature URL ending
- **4**: Prepend long random string
- **5**: Fake parameter
- **6**: TAB as request spacer
- **7**: Change case of URL
- **8**: Use Windows directory separator (\)
## Security Considerations
### Authorization & Legal Compliance
- **Written Permission**: Obtain explicit authorization for web server scanning
- **Scope Verification**: Only scan explicitly authorized hosts and ports
- **Detection Risk**: Nikto is noisy and will trigger IDS/IPS alerts
- **Production Impact**: Scans may impact server performance
- **Log Flooding**: Nikto generates extensive log entries
### Operational Security
- **Rate Limiting**: Use -Pause to reduce server load
- **Scan Windows**: Perform scans during approved maintenance windows
- **Session Management**: Use -maxtime to limit scan duration
- **Proxy Usage**: Route through authorized proxy if required
- **User-Agent**: Consider using custom User-Agent for tracking
### Audit Logging
Document all Nikto scanning activities:
- Target hosts and ports scanned
- Scan start and end timestamps
- Tuning options and plugins used
- Findings and vulnerability counts
- False positives identified
- Remediation priorities
- Report delivery and recipients
### Compliance
- **OWASP ASVS**: V14 Configuration Verification
- **NIST SP 800-115**: Technical Guide to Information Security Testing
- **PCI-DSS**: 6.6 and 11.3 - Vulnerability scanning
- **CWE**: Common Weakness Enumeration mapping
- **ISO 27001**: A.12.6 - Technical vulnerability management
## Common Patterns
### Pattern 1: External Perimeter Assessment
```bash
# Scan external web servers
for host in web1.example.com web2.example.com; do
nikto -h https://$host -o nikto_${host}.html -Format html
done
# Scan common web ports
nikto -h example.com -p 80,443,8080,8443 -o external_scan.txt
```
### Pattern 2: Internal Web Application Assessment
```bash
# Comprehensive internal scan
nikto -h http://intranet.local \
-Tuning 123456789abcde \
-timeout 30 \
-maxtime 2h \
-o internal_assessment.html -Format html
```
### Pattern 3: SSL/TLS Security Assessment
```bash
# SSL-specific testing
nikto -h https://example.com \
-Plugins "ssl" \
-ssl \
-o ssl_assessment.txt
```
### Pattern 4: Authenticated Scanning
```bash
# Scan with authentication
nikto -h http://example.com \
-id admin:password \
-cookies "sessionid=abc123" \
-Tuning 123456789 \
-o authenticated_scan.html -Format html
```
### Pattern 5: Bulk Scanning
```bash
# Create host file
cat > web_servers.txt <<EOF
http://web1.example.com
https://web2.example.com:8443
http://web3.example.com:8080
EOF
# Scan all hosts
nikto -h web_servers.txt -o bulk_scan.csv -Format csv
```
## Integration Points
### CI/CD Integration
```bash
#!/bin/bash
# ci_nikto_scan.sh - Automated web security scanning
TARGET_URL="$1"
OUTPUT_DIR="nikto_results/$(date +%Y%m%d_%H%M%S)"
mkdir -p "$OUTPUT_DIR"
# Run Nikto scan
nikto -h "$TARGET_URL" \
-Tuning 123456789 \
-maxtime 30m \
-o "$OUTPUT_DIR/nikto_report.xml" -Format xml
# Check for critical findings
if grep -i "OSVDB" "$OUTPUT_DIR/nikto_report.xml"; then
echo "CRITICAL: Vulnerabilities detected!"
exit 1
fi
echo "Scan completed successfully"
exit 0
```
### SIEM Integration
```bash
# Export findings to JSON for SIEM
nikto -h http://example.com -o findings.xml -Format xml
# Parse XML to JSON (requires xmlstarlet or similar)
xmlstarlet sel -t -m "//item" -v "concat(@id,',',description,','
,uri)" -n findings.xml > findings.csv
```
## Troubleshooting
### Issue: Scan Takes Too Long
**Solutions**:
```bash
# Limit scan duration
nikto -h http://example.com -maxtime 15m
# Reduce tuning scope
nikto -h http://example.com -Tuning 123
# Disable 404 checking
nikto -h http://example.com -no404
```
### Issue: SSL/TLS Errors
**Solutions**:
```bash
# Force SSL
nikto -h example.com -ssl -p 443
# Ignore SSL certificate errors
nikto -h https://example.com -ssl -nossl
# Specify SSL version
nikto -h https://example.com -ssl
```
### Issue: Too Many False Positives
**Solutions**:
- Manually verify findings
- Use -Tuning to focus on specific vulnerability types
- Review and update Nikto database with -update
- Exclude known false positives from reports
### Issue: WAF Blocking Scans
**Solutions**:
```bash
# Use evasion techniques
nikto -h http://example.com -evasion 1234567
# Add delays
nikto -h http://example.com -Pause 10
# Use custom User-Agent
nikto -h http://example.com -useragent "legitimate-browser-string"
```
## Defensive Considerations
Protect web servers against Nikto scanning:
**Web Application Firewall Rules**:
- Detect and block Nikto User-Agent strings
- Implement rate limiting
- Block known Nikto attack patterns
- Monitor for scan signatures
**Server Hardening**:
- Remove default files and directories
- Disable directory listing
- Remove server version banners
- Apply security patches regularly
- Follow CIS benchmarks for web server hardening
**Detection and Monitoring**:
- Monitor for rapid sequential requests
- Alert on multiple 404 errors from single source
- Detect common vulnerability probes
- Log and correlate scan patterns
- Implement honeypot files/directories
Common Nikto detection signatures:
- User-Agent contains "Nikto"
- Requests to known vulnerable paths
- Sequential URI enumeration
- Specific HTTP header patterns

# What to report when found
message: |
Potential SQL injection vulnerability detected. SQL query is constructed using
string concatenation or f-strings with user input. This allows attackers to
inject malicious SQL code.
Use parameterized queries instead:
- Python: cursor.execute("SELECT * FROM users WHERE id = ?", (user_id,))
- JavaScript: db.query("SELECT * FROM users WHERE id = $1", [userId])
See: https://owasp.org/www-community/attacks/SQL_Injection
# Suggested fix (auto-fix if supported)
fix: |
Use parameterized queries with placeholders
# Example vulnerable code

---
## Document Organization
### Structure for Long Documents
For references >100 lines:
```markdown
# Title
**When to use**: Clear trigger statement
**Purpose**: What this provides
## Table of Contents
- Links to all major sections
## Quick Reference
- Key facts or commands for fast lookup
## Detailed Content
- Comprehensive information organized logically
## Framework Mappings
- OWASP, CWE, MITRE ATT&CK references
## Examples
- Code samples and patterns
```
### Section Naming Conventions
- Use **imperative** or **declarative** headings
- ✅ "Detecting SQL Injection" not "How to detect SQL Injection"
- ✅ "Common Patterns" not "These are common patterns"
- Make headings **searchable** and **specific**
---
## Detailed Technical Content
This section demonstrates the type of detailed content that belongs in references rather than SKILL.md.
### Example: Comprehensive Vulnerability Detection
#### SQL Injection Detection Patterns
**Pattern 1: String Concatenation in Queries**
```python
# Vulnerable pattern
query = "SELECT * FROM users WHERE id = " + user_id
cursor.execute(query)
# Detection criteria:
# - SQL keyword (SELECT, INSERT, UPDATE, DELETE)
# - String concatenation operator (+, f-string)
# - Variable user input (request params, form data)
# Severity: HIGH
# CWE: CWE-89
# OWASP: A03:2021 - Injection
```
**Remediation**:
```python
# Fixed: Parameterized query
query = "SELECT * FROM users WHERE id = ?"
cursor.execute(query, (user_id,))
# OR using ORM
user = User.objects.get(id=user_id)
```
**Pattern 2: Unsafe String Formatting**
```python
# Vulnerable patterns
query = f"SELECT * FROM users WHERE name = '{username}'"
query = "SELECT * FROM users WHERE name = '%s'" % username
query = "SELECT * FROM users WHERE name = '{}'".format(username)
# All three patterns are vulnerable to SQL injection
```
#### Cross-Site Scripting (XSS) Detection
**Pattern 1: Unescaped Output in Templates**
```javascript
// Vulnerable: Direct HTML injection
element.innerHTML = userInput;
document.write(userInput);
// Vulnerable: React dangerouslySetInnerHTML
<div dangerouslySetInnerHTML={{__html: userComment}} />
// Detection criteria:
# - Direct DOM manipulation (innerHTML, document.write)
# - React dangerouslySetInnerHTML with user data
# - Template engines with autoescaping disabled
// Severity: HIGH
// CWE: CWE-79
// OWASP: A03:2021 - Injection
```
**Remediation**:
```javascript
// Fixed: Escaped output
element.textContent = userInput; // Auto-escapes
// Fixed: Sanitization library
import DOMPurify from 'dompurify';
const clean = DOMPurify.sanitize(userComment);
<div dangerouslySetInnerHTML={{__html: clean}} />
```

## Remediation Patterns
This section provides specific remediation guidance for common vulnerability types.
### SQL Injection Remediation
**Step 1: Identify vulnerable queries**
- Search for string concatenation in SQL queries
- Check for f-strings or format() with SQL keywords
- Review all database interaction code
**Step 2: Apply parameterized queries**
```python
# Python with sqlite3
cursor.execute("SELECT * FROM users WHERE id = ?", (user_id,))
# Python with psycopg2 (PostgreSQL)
cursor.execute("SELECT * FROM users WHERE id = %s", (user_id,))
# Python with SQLAlchemy (ORM)
from sqlalchemy import text
result = session.execute(text("SELECT * FROM users WHERE id = :id"), {"id": user_id})
```
**Step 3: Validate and sanitize input** (defense in depth)
```python
import re
# Validate input format
if not re.match(r'^\d+$', user_id):
raise ValueError("Invalid user ID format")
# Use ORM query builders
user = User.query.filter_by(id=user_id).first()
```
**Step 4: Implement least privilege**
- Database user should have minimum required permissions
- Use read-only accounts for SELECT operations
- Never use admin/root accounts for application queries
### XSS Remediation
**Step 1: Enable auto-escaping**
- Most modern frameworks escape by default
- Ensure auto-escaping is not disabled
**Step 2: Use framework-specific safe methods**
```javascript
// React: Use JSX (auto-escapes)
<div>{userInput}</div>
// Vue: Use template syntax (auto-escapes)
<div>{{ userInput }}</div>
// Angular: Use property binding (auto-escapes)
<div [textContent]="userInput"></div>
```
**Step 3: Sanitize when HTML is required**
```javascript
import DOMPurify from 'dompurify';
// Sanitize HTML content
const clean = DOMPurify.sanitize(userHTML, {
ALLOWED_TAGS: ['b', 'i', 'em', 'strong', 'p'],
ALLOWED_ATTR: []
});
```
**Step 4: Content Security Policy (CSP)**
```html
<!-- Add CSP header -->
Content-Security-Policy: default-src 'self'; script-src 'self' 'nonce-{random}'
```

---
## Examples and Code Samples
This section provides comprehensive code examples for various scenarios.
### Example 1: Secure API Authentication
```python
# Secure API key handling
import os
from functools import wraps
from flask import Flask, request, jsonify
app = Flask(__name__)
# Load API key from environment (never hardcode)
VALID_API_KEY = os.environ.get('API_KEY')
if not VALID_API_KEY:
raise ValueError("API_KEY environment variable not set")
def require_api_key(f):
@wraps(f)
def decorated_function(*args, **kwargs):
api_key = request.headers.get('X-API-Key')
if not api_key:
return jsonify({'error': 'API key required'}), 401
# Constant-time comparison to prevent timing attacks
import hmac
if not hmac.compare_digest(api_key, VALID_API_KEY):
return jsonify({'error': 'Invalid API key'}), 403
return f(*args, **kwargs)
return decorated_function
@app.route('/api/secure-endpoint')
@require_api_key
def secure_endpoint():
return jsonify({'message': 'Access granted'})
```
### Example 2: Secure Password Hashing
```python
# Secure password storage with bcrypt
import bcrypt
def hash_password(password: str) -> str:
"""Hash a password using bcrypt."""
# Generate salt and hash password
salt = bcrypt.gensalt(rounds=12) # Cost factor: 12 (industry standard)
hashed = bcrypt.hashpw(password.encode('utf-8'), salt)
return hashed.decode('utf-8')
def verify_password(password: str, hashed: str) -> bool:
"""Verify a password against a hash."""
return bcrypt.checkpw(
password.encode('utf-8'),
hashed.encode('utf-8')
)
# Usage
stored_hash = hash_password("user_password")
is_valid = verify_password("user_password", stored_hash) # True
```
### Example 3: Secure File Upload
```python
# Secure file upload with validation
import os
import magic
from werkzeug.utils import secure_filename
ALLOWED_EXTENSIONS = {'pdf', 'png', 'jpg', 'jpeg'}
ALLOWED_MIME_TYPES = {
'application/pdf',
'image/png',
'image/jpeg'
}
MAX_FILE_SIZE = 5 * 1024 * 1024 # 5 MB
def is_allowed_file(filename: str, file_content: bytes) -> bool:
"""Validate file extension and MIME type."""
# Check extension
if '.' not in filename:
return False
ext = filename.rsplit('.', 1)[1].lower()
if ext not in ALLOWED_EXTENSIONS:
return False
# Check MIME type (prevent extension spoofing)
mime = magic.from_buffer(file_content, mime=True)
if mime not in ALLOWED_MIME_TYPES:
return False
return True
def handle_upload(file):
"""Securely handle file upload."""
# Check file size
file.seek(0, os.SEEK_END)
size = file.tell()
file.seek(0)
if size > MAX_FILE_SIZE:
raise ValueError("File too large")
# Read content for validation
content = file.read()
file.seek(0)
# Validate file type
if not is_allowed_file(file.filename, content):
raise ValueError("Invalid file type")
# Sanitize filename
filename = secure_filename(file.filename)
# Generate unique filename to prevent overwrite attacks
import uuid
unique_filename = f"{uuid.uuid4()}_{filename}"
# Save to secure location (outside web root)
upload_path = os.path.join('/secure/uploads', unique_filename)
file.save(upload_path)
return unique_filename
```

## Best Practices for Reference Documents
1. **Start with "When to use"** - Help Claude know when to load this reference
2. **Include table of contents** - For documents >100 lines
3. **Use concrete examples** - Code samples with vulnerable and fixed versions
4. **Map to frameworks** - OWASP, CWE, MITRE ATT&CK for context
5. **Provide remediation** - Don't just identify issues, show how to fix them
6. **Organize logically** - Group related content, use clear headings
7. **Keep examples current** - Use modern patterns and current framework versions
8. **Be concise** - Even in references, challenge every sentence

# Workflow Checklist Template
This template demonstrates workflow patterns for security operations. Copy and adapt these checklists to your specific skill needs.
## Pattern 1: Sequential Workflow Checklist
Use this pattern for operations that must be completed in order, step-by-step.
### Security Assessment Workflow
Progress:
[ ] 1. Identify application entry points and attack surface
[ ] 2. Map authentication and authorization flows
[ ] 3. Identify data flows and sensitive data handling
[ ] 4. Review existing security controls
[ ] 5. Document findings with framework references (OWASP, CWE)
[ ] 6. Prioritize findings by severity (CVSS scores)
[ ] 7. Generate report with remediation recommendations
Work through each step systematically. Check off completed items.
---
## Pattern 2: Conditional Workflow
Use this pattern when the workflow branches based on findings or conditions.
### Vulnerability Remediation Workflow
1. Identify vulnerability type
- If SQL Injection → See [sql-injection-remediation.md](sql-injection-remediation.md)
- If XSS (Cross-Site Scripting) → See [xss-remediation.md](xss-remediation.md)
- If Authentication flaw → See [auth-remediation.md](auth-remediation.md)
- If Authorization flaw → See [authz-remediation.md](authz-remediation.md)
- If Cryptographic issue → See [crypto-remediation.md](crypto-remediation.md)
2. Assess severity using CVSS calculator
- If CVSS >= 9.0 → Priority: Critical (immediate action)
- If CVSS 7.0-8.9 → Priority: High (action within 24h)
- If CVSS 4.0-6.9 → Priority: Medium (action within 1 week)
- If CVSS < 4.0 → Priority: Low (action within 30 days)
3. Apply appropriate remediation pattern
4. Validate fix with security testing
5. Document changes and update security documentation
---
## Pattern 3: Iterative Workflow
Use this pattern for operations that repeat across multiple targets or items.
### Code Security Review Workflow
For each file in the review scope:
1. Identify security-sensitive operations (auth, data access, crypto, input handling)
2. Check against secure coding patterns for the language
3. Flag potential vulnerabilities with severity rating
4. Map findings to CWE and OWASP categories
5. Suggest specific remediation approaches
6. Document finding with code location and fix priority
Continue until all files in scope have been reviewed.
---
## Pattern 4: Feedback Loop Workflow
Use this pattern when validation and iteration are required.
### Secure Configuration Generation Workflow
1. Generate initial security configuration based on requirements
2. Run validation script: `./scripts/validate_config.py config.yaml`
3. Review validation output:
- Note all errors (must fix)
- Note all warnings (should fix)
- Note all info items (consider)
4. Fix identified issues in configuration
5. Repeat steps 2-4 until validation passes with zero errors
6. Review warnings and determine if they should be addressed
7. Apply configuration once validation is clean
**Validation Loop**: Run validator → Fix errors → Repeat until clean
---
## Pattern 5: Parallel Analysis Workflow
Use this pattern when multiple independent analyses can run concurrently.
### Comprehensive Security Scan Workflow
Run these scans in parallel:
**Static Analysis**:
[ ] 1a. Run SAST scan (Semgrep/Bandit)
[ ] 1b. Run dependency vulnerability scan (Safety/npm audit)
[ ] 1c. Run secrets detection (Gitleaks/TruffleHog)
[ ] 1d. Run license compliance check
**Dynamic Analysis**:
[ ] 2a. Run DAST scan (ZAP/Burp)
[ ] 2b. Run API security testing
[ ] 2c. Run authentication/authorization testing
**Infrastructure Analysis**:
[ ] 3a. Run infrastructure-as-code scan (Checkov/tfsec)
[ ] 3b. Run container image scan (Trivy/Grype)
[ ] 3c. Run configuration review
**Consolidation**:
[ ] 4. Aggregate all findings
[ ] 5. Deduplicate and correlate findings
[ ] 6. Prioritize by risk (CVSS + exploitability + business impact)
[ ] 7. Generate unified security report
---
## Pattern 6: Research and Documentation Workflow
Use this pattern for security research and documentation tasks.
### Threat Modeling Workflow
Research Progress:
[ ] 1. Identify system components and boundaries
[ ] 2. Map data flows between components
[ ] 3. Identify trust boundaries
[ ] 4. Enumerate assets (data, services, credentials)
[ ] 5. Apply STRIDE framework to each component:
- Spoofing threats
- Tampering threats
- Repudiation threats
- Information disclosure threats
- Denial of service threats
- Elevation of privilege threats
[ ] 6. Map threats to MITRE ATT&CK techniques
[ ] 7. Identify existing mitigations
[ ] 8. Document residual risks
[ ] 9. Recommend additional security controls
[ ] 10. Generate threat model document
Work through each step systematically. Check off completed items.
---
## Pattern 7: Compliance Validation Workflow
Use this pattern for compliance checks against security standards.
### Security Compliance Audit Workflow
**SOC 2 Controls Review**:
[ ] 1. Review access control policies (CC6.1, CC6.2, CC6.3)
[ ] 2. Verify logical access controls implementation (CC6.1)
[ ] 3. Review authentication mechanisms (CC6.1)
[ ] 4. Verify encryption implementation (CC6.1, CC6.7)
[ ] 5. Review audit logging configuration (CC7.2)
[ ] 6. Verify security monitoring (CC7.2, CC7.3)
[ ] 7. Review incident response procedures (CC7.3, CC7.4)
[ ] 8. Verify backup and recovery processes (A1.2, A1.3)
**Evidence Collection**:
[ ] 9. Collect policy documents
[ ] 10. Collect configuration screenshots
[ ] 11. Collect audit logs
[ ] 12. Document control gaps
[ ] 13. Generate compliance report
---
## Pattern 8: Incident Response Workflow
Use this pattern for security incident handling.
### Security Incident Response Workflow
**Detection and Analysis**:
[ ] 1. Confirm security incident (rule out false positive)
[ ] 2. Determine incident severity (SEV1/2/3/4)
[ ] 3. Identify affected systems and data
[ ] 4. Preserve evidence (logs, memory dumps, network captures)
**Containment**:
[ ] 5. Isolate affected systems (network segmentation)
[ ] 6. Disable compromised accounts
[ ] 7. Block malicious indicators (IPs, domains, hashes)
[ ] 8. Implement temporary compensating controls
**Eradication**:
[ ] 9. Identify root cause
[ ] 10. Remove malicious artifacts (malware, backdoors, webshells)
[ ] 11. Patch vulnerabilities exploited
[ ] 12. Reset compromised credentials
**Recovery**:
[ ] 13. Restore systems from clean backups (if needed)
[ ] 14. Re-enable systems with monitoring
[ ] 15. Verify system integrity
[ ] 16. Resume normal operations
**Post-Incident**:
[ ] 17. Document incident timeline
[ ] 18. Identify lessons learned
[ ] 19. Update security controls to prevent recurrence
[ ] 20. Update incident response procedures
[ ] 21. Communicate with stakeholders

## Usage Guidelines
### When to Use Workflow Checklists
✅ **Use checklists for**:
- Complex multi-step operations
- Operations requiring specific order
- Security assessments and audits
- Incident response procedures
- Compliance validation tasks
❌ **Don't use checklists for**:
- Simple single-step operations
- Highly dynamic exploratory work
- Operations that vary significantly each time
### Adapting This Template
1. **Copy relevant pattern** to your skill's SKILL.md or create new reference file
2. **Customize steps** to match your specific security tool or process
3. **Add framework references** (OWASP, CWE, NIST) where applicable
4. **Include tool-specific commands** for automation
5. **Add decision points** where manual judgment is required
### Checklist Best Practices
- **Be specific**: "Run semgrep --config=auto ." not "Scan the code"
- **Include success criteria**: "Validation passes with 0 errors"
- **Reference standards**: Link to OWASP, CWE, NIST where relevant
- **Show progress**: Checkbox format helps track completion
- **Provide escape hatches**: "If validation fails, see troubleshooting.md"
### Integration with Feedback Loops
Combine checklists with validation scripts for maximum effectiveness:
1. Create checklist for the workflow
2. Provide validation script that checks quality
3. Include "run validator" step in checklist
4. Loop: Complete step → Validate → Fix issues → Re-validate
This pattern dramatically improves output quality through systematic validation.
