Privileges Required (None/Low/High)
User Interaction (None/Required)
Scope (Unchanged/Changed)
Confidentiality Impact (None/Low/High)
Integrity Impact (None/Low/High)
Availability Impact (None/Low/High)

OWASP Top 10 (2021) Mapping

A01:2021 - Broken Access Control → CWE-639, CWE-284, CWE-285, CWE-862
A02:2021 - Cryptographic Failures → CWE-327, CWE-328, CWE-329, CWE-326
A03:2021 - Injection → CWE-89, CWE-79, CWE-78, CWE-94, CWE-95
A04:2021 - Insecure Design → CWE-209, CWE-256, CWE-501, CWE-522

A10:2021 - SSRF → CWE-918

Use Cases

1. Analyze Finding Severity

Input: Security finding from scanner Output: CVSS score, severity classification, justification

Example:

Finding: SQL Injection in user login (CWE-89)
Location: src/auth.py:42

CVSS v3.1 Score: 9.8 (CRITICAL)
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Justification:
- Attack Vector (N): Exploitable remotely over network
- Attack Complexity (L): No special conditions required
- Privileges Required (N): No authentication needed
- User Interaction (N): No user interaction required
- Scope (U): Scope unchanged
- Confidentiality (H): Full database access possible
- Integrity (H): Data modification/deletion possible
- Availability (H): Database could be dropped

Business Impact: CRITICAL - Authentication bypass allows full system compromise

2. Assess Business Impact

Input: Vulnerability details Output: Business impact analysis

Example:

Vulnerability: Hardcoded API credentials (CWE-798)

Business Impact Analysis:
- Financial Risk: $500K-$2M (data breach costs, regulatory fines)
- Reputation Risk: HIGH (customer trust, brand damage)
- Regulatory Risk: SOC2 Type II failure, potential PCI-DSS non-compliance
- Operational Risk: Service disruption if credentials rotated

Affected Assets:
- Customer PII database (100K+ records)
- Payment processing API
- Internal admin systems

Recommended Action: IMMEDIATE remediation required (24-48 hour SLA)

3. Map to Compliance Requirements

Input: Security finding Output: Compliance control mapping

Example:

Finding: Missing encryption for data at rest (CWE-311)

Compliance Mapping:
SOC2 (Trust Services Criteria):
- CC6.7: Encryption of confidential information at rest
- CC6.1: Logical and physical access controls

ISO 27001:2022:
- A.8.24: Use of cryptography
- A.5.33: Protection of records

PCI-DSS v4.0:
- Requirement 3.5.1: Encryption of cardholder data at rest
- Requirement 3.6.1: Cryptographic key management

HIPAA Security Rule:
- 164.312(a)(2)(iv): Encryption (Addressable)
- 164.312(e)(2)(ii): Encryption (Addressable)

Remediation Priority: HIGH - Multiple compliance frameworks affected
Audit Impact: Would result in findings/exceptions during next audit

4. Explain Vulnerability to Non-Technical Stakeholders

Input: Technical finding Output: Executive summary

Example:

EXECUTIVE SUMMARY: SQL Injection Vulnerability

What Is It?
A security flaw that allows attackers to manipulate database queries through user input fields.

Business Risk:
- Attackers can steal all customer data (names, emails, passwords)
- Potential data breach affecting 100,000+ customers
- Regulatory fines: $50K-$500K (GDPR, state privacy laws)
- Average cost of data breach: $4.35M (IBM 2023 report)

How Serious?
CRITICAL - This is a "break glass" priority. Can be exploited in minutes by anyone with internet access.

Comparable To:
Leaving your bank vault door wide open with a "please don't steal" sign.

What Happens Next?
1. Emergency patch deployed (24 hours)
2. Security audit of similar code (1 week)
3. Post-incident review (2 weeks)

5. Provide Remediation Guidance

Input: Classified vulnerability Output: Prioritized remediation plan

Example:

Finding: CWE-79 (XSS) in user profile page

Remediation Plan:

IMMEDIATE (0-24 hours):
1. Deploy input sanitization using framework escaping
   - Python: use markupsafe.escape() or framework auto-escaping
   - Estimated effort: 2 hours
   - Risk reduction: 80%

SHORT-TERM (1-7 days):
2. Implement Content Security Policy (CSP) headers
   - Header: Content-Security-Policy: default-src 'self'
   - Estimated effort: 4 hours
   - Risk reduction: 95%

3. Code review of all user input handling
   - Review 20 endpoints
   - Estimated effort: 1 day
   - Risk reduction: 98%

LONG-TERM (1-4 weeks):
4. Add automated XSS testing to CI/CD
   - Tool: OWASP ZAP or Burp Suite
   - Estimated effort: 3 days
   - Prevents regression

Total Risk Reduction: 98% (from CRITICAL to LOW residual risk)
Cost: ~$5K (40 hours @ $125/hr)
ROI: Prevents $500K+ breach cost

Example Interactions

Q: "Analyze this SQL injection finding"

Input:

{
  "id": "SEMGREP-001",
  "cwe_id": "CWE-89",
  "title": "SQL Injection in login endpoint",
  "severity": "high",
  "location": {
    "file": "src/auth.py",
    "line_start": 42,
    "code_snippet": "query = f\"SELECT * FROM users WHERE username = '{username}'\""
  }
}

Analysis:

Classification: TRUE POSITIVE (Confidence: 0.95)

CVSS v3.1 Score: 9.8 (CRITICAL) Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Risk Analysis:

Impact: 10/10 (Full database compromise)
Exploitability: 9/10 (Trivial - basic SQL injection)
Detection Time: 30 days
Risk Score: (10 × 9) / 30 = 3.0 (HIGH)

OWASP Mapping: A03:2021 - Injection

Compliance Impact:

SOC2: CC6.1 (Logical access controls) - FAIL
PCI-DSS 6.5.1: Injection flaws - NON-COMPLIANT
ISO 27001 A.14.2.5: Secure system principles - CONTROL GAP

Explanation:

What: User input concatenated directly into SQL query without sanitization
Why It Matters: Attacker can bypass authentication, steal all user data, or delete entire database
How to Exploit: Enter ' OR 1=1 -- in username field to bypass login
How to Fix: Use parameterized query: cursor.execute("SELECT * FROM users WHERE username = %s", (username,))

Remediation Priority: P0 (Emergency) - Deploy fix within 24 hours

Q: "What's the business impact of this hardcoded secret?"

Input:

# src/config.py
API_KEY = "sk-abc123xyz789secret"

Analysis:

Business Impact Assessment:

Financial Risk: $250K-$1M

Average data breach cost: $4.35M (IBM)
Scope: ~50K affected records
Regulatory fines: GDPR up to €20M or 4% revenue

Reputation Risk: HIGH

Customer trust degradation
Negative press coverage
Competitor advantage

Operational Risk: MEDIUM

Service disruption during credential rotation
Emergency incident response costs
Customer notification requirements

Regulatory/Compliance Risk: CRITICAL

SOC2 Type II: Likely failure of CC6.1, CC6.2 controls
ISO 27001: A.9.4.3 (Password management) violation
PCI-DSS: Requirement 8 (Access control) non-compliance

Likelihood: HIGH (Credentials in source code, likely in Git history)

Recommended Actions:

IMMEDIATE: Revoke exposed credentials (within 1 hour)
URGENT: Audit access logs for unauthorized use (within 24 hours)
SHORT-TERM: Implement secrets manager (within 1 week)
LONG-TERM: Git history rewrite + force push (within 2 weeks)

Executive Summary: "This is equivalent to publishing your bank account password on your company website. Fix immediately before attackers discover it."

Q: "How do I prioritize these 50 findings?"

Analysis:

Triage Framework:

Tier 1: CRITICAL (Fix in 0-24 hours)

CVSS 9.0-10.0
Authentication bypass
Remote code execution
SQL injection in public endpoints
Hardcoded production credentials

Tier 2: HIGH (Fix in 1-7 days)

CVSS 7.0-8.9
XSS in user-facing features
Path traversal with limited scope
Weak cryptography for sensitive data
Broken access control

Tier 3: MEDIUM (Fix in 1-4 weeks)

CVSS 4.0-6.9
Information disclosure (non-PII)
Missing security headers
Weak password policies
Insecure dependencies (no known exploits)

Tier 4: LOW (Fix in next sprint/backlog)

CVSS 0.1-3.9
Code quality issues
Theoretical vulnerabilities
False positives pending verification

Prioritization Criteria:

CVSS score (40% weight)
Exploitability (30% weight)
Compliance impact (20% weight)
Business criticality of affected asset (10% weight)

Risk Score Formula: risk_score = (impact × exploitability) / detection_time

Sort findings by risk_score descending, then apply tier framework.
