Detection Methods

Automated Static Analysis - Binary or Bytecode

According to SOAR [REF-1479], the following detection techniques may be useful: Cost effective for partial coverage: Inter-application Flow Analysis

Manual Static Analysis - Binary or Bytecode

According to SOAR [REF-1479], the following detection techniques may be useful: Cost effective for partial coverage: Binary / Bytecode disassembler - then use manual analysis for vulnerabilities & anomalies

Dynamic Analysis with Automated Results Interpretation

According to SOAR [REF-1479], the following detection techniques may be useful: Cost effective for partial coverage: Host-based Vulnerability Scanners - Examine configuration for flaws, verifying that audit mechanisms work, ensure host configuration meets certain predefined criteria Web Application Scanner Web Services Scanner Database Scanners

Dynamic Analysis with Manual Results Interpretation

According to SOAR [REF-1479], the following detection techniques may be useful: Highly cost effective: Host Application Interface Scanner Cost effective for partial coverage: Fuzz Tester Framework-based Fuzzer Automated Monitored Execution Forced Path Execution

Manual Static Analysis - Source Code

According to SOAR [REF-1479], the following detection techniques may be useful: Highly cost effective: Manual Source Code Review (not inspections) Cost effective for partial coverage: Focused Manual Spotcheck - Focused manual analysis of source

Automated Static Analysis - Source Code

According to SOAR [REF-1479], the following detection techniques may be useful: Cost effective for partial coverage: Context-configured Source Code Weakness Analyzer

Automated Static Analysis

According to SOAR [REF-1479], the following detection techniques may be useful: Cost effective for partial coverage: Configuration Checker

Architecture or Design Review

According to SOAR [REF-1479], the following detection techniques may be useful: Highly cost effective: Formal Methods / Correct-By-Construction Cost effective for partial coverage: Inspection (IEEE 1028 standard) (can apply to requirements, design, source code, etc.)
