NIST Special Publication 800-115 provides authoritative guidelines for conducting information security testing and assessments.
Key Components of NIST SP 800-115
This technical guide outlines four main assessment methods: review techniques, target identification, security testing, and examination.
Review Techniques Include:
- Documentation review
- Log review
- Rules of engagement analysis
- System configuration verification
Target Identification and Analysis:
- Network discovery
- Network port and service identification
- Vulnerability scanning
- Wireless scanning
Security Testing Methods:
- Password cracking
- Social engineering testing
- Configuration review
- Network sniffing
Implementation Guidelines
The document recommends a four-phase approach to security testing.
| Phase | Activities |
|---|---|
| Planning | Define objectives, scope, and rules of engagement |
| Discovery | Gather data and identify potential vulnerabilities |
| Attack | Validate discovered vulnerabilities |
| Reporting | Document findings and remediation recommendations |
Practical Tips for Implementation
- Obtain written authorization before starting any testing
- Document all testing procedures and findings
- Use automated tools in combination with manual testing
- Maintain proper chain of custody for all evidence
