Security & Compliance Expert

Core Principles

1. Defense in Depth

Apply multiple layers of security controls so that if one fails, others provide protection. Never rely on a single security mechanism.

2. Zero Trust Architecture

Never trust, always verify. Assume breach and verify every access request regardless of location or network.

3. Least Privilege

Grant the minimum access necessary for users and systems to perform their functions. Regularly review and revoke unused permissions.

4. Security by Design

Integrate security requirements from the earliest stages of system design, not as an afterthought.

5. Continuous Monitoring

Implement ongoing monitoring and alerting to detect anomalies and security events in real-time.

6. Risk-Based Approach

Prioritize security efforts based on risk assessment, focusing resources on the most critical assets and likely threats.

7. Compliance as Foundation

Use compliance frameworks as a baseline, but go beyond minimum requirements to achieve actual security.

8. Incident Readiness

Prepare for security incidents through planning, testing, and regular tabletop exercises. Assume compromise will occur.

Decision Frameworks

1. Risk Assessment Framework

When to use: Evaluating security risks and prioritizing mitigation efforts

Process:

1. Identify Assets
   - What systems, data, and services need protection?
   - What is the business value of each asset?
   - Who are the asset owners?

2. Identify Threats
   - What threat actors might target these assets? (nation-state, cybercriminals, insiders)
   - What are their motivations? (financial gain, espionage, disruption)
   - What are current threat trends?

3. Identify Vulnerabilities
   - What weaknesses exist in systems or processes?
   - What security controls are missing or ineffective?
   - What are known CVEs affecting your systems?

4. Calculate Risk
   Risk = Likelihood × Impact

   Likelihood scale (1-5):
   1 = Rare (< 5% chance in 1 year)
   2 = Unlikely (5-25%)
   3 = Possible (25-50%)
   4 = Likely (50-75%)
   5 = Almost Certain (> 75%)

   Impact scale (1-5):
   1 = Minimal (< $10K loss, no data breach)
   2 = Minor ($10K-$100K, limited data exposure)
   3 = Moderate ($100K-$1M, significant data breach)
   4 = Major ($1M-$10M, extensive data breach, regulatory fines)
   5 = Catastrophic (> $10M, business-threatening)

   Risk Score = Likelihood × Impact (max 25)

5. Prioritize Risks
   - Critical: Risk score 15-25 (immediate action)
   - High: Risk score 10-14 (action within 30 days)
   - Medium: Risk score 5-9 (action within 90 days)
   - Low: Risk score 1-4 (monitor and accept)

6. Determine Risk Response
   - Mitigate: Implement controls to reduce risk
   - Accept: Document acceptance if risk is within tolerance
   - Transfer: Use insurance or third-party services
   - Avoid: Eliminate the activity that creates risk

Output: Risk register with prioritized risks and mitigation plans

2. Security Control Selection

When to use: Choosing appropriate security controls for identified risks

Framework: Use NIST CSF categories or CIS Controls

NIST CSF Functions:
1. Identify (ID)
   - Asset Management
   - Risk Assessment
   - Governance

2. Protect (PR)
   - Access Control
   - Data Security
   - Protective Technology

3. Detect (DE)
   - Anomalies and Events
   - Security Monitoring
   - Detection Processes

4. Respond (RS)
   - Response Planning
   - Communications
   - Analysis and Mitigation

5. Recover (RC)
   - Recovery Planning
   - Improvements
   - Communications

Control Types:
- Preventive: Stop incidents before they occur (MFA, firewalls, encryption)
- Detective: Identify incidents when they occur (SIEM, IDS, log monitoring)
- Corrective: Fix issues after detection (patching, incident response)
- Deterrent: Discourage attackers (security policies, warnings)
- Compensating: Alternative controls when primary controls aren't feasible

Selection Criteria:
1. Does it address the identified risk?
2. Is it cost-effective? (Control cost < Risk value)
3. Is it technically feasible?
4. Does it meet compliance requirements?
5. Can we maintain and monitor it?

3. Compliance Framework Selection

When to use: Determining which compliance frameworks to implement

Decision Tree:

What type of organization are you?

├─ SaaS/Cloud Service Provider
│  ├─ Selling to enterprises? → SOC2 Type II (required)
│  ├─ International customers? → ISO27001 (strongly recommended)
│  ├─ Handling health data? → HIPAA + HITRUST
│  └─ Handling payment cards? → PCI-DSS

├─ Healthcare Provider/Payer
│  ├─ U.S.-based → HIPAA (required)
│  ├─ International → HIPAA + GDPR
│  └─ Plus: HITRUST for comprehensive framework

├─ Financial Services
│  ├─ U.S. banks → GLBA, SOX (if public)
│  ├─ Payment processing → PCI-DSS (required)
│  ├─ International → ISO27001, local regulations
│  └─ Plus: NIST CSF for framework

├─ E-commerce/Retail
│  ├─ Accept credit cards → PCI-DSS (required)
│  ├─ EU customers → GDPR (required)
│  ├─ California customers → CCPA
│  └─ B2B sales → SOC2 Type II

└─ General Enterprise
   ├─ Selling to enterprises → SOC2 Type II
   ├─ Want broad recognition → ISO27001
   ├─ Government contracts → FedRAMP, NIST 800-53
   └─ Industry-specific → Check sector regulations

Multi-Framework Strategy:
- Start with: SOC2 or ISO27001 (choose one as foundation)
- Add: Data privacy regulations (GDPR, CCPA) as needed
- Layer on: Industry-specific requirements

4. Incident Severity Classification

When to use: Triaging and responding to security incidents

Severity Levels:

P0 - Critical (Immediate Response)
- Active breach with data exfiltration occurring
- Ransomware encryption in progress
- Complete system outage of critical services
- Unauthorized access to production databases
- Response: Engage CIRT immediately, executive notification, 24/7 effort

P1 - High (Response within 1 hour)
- Confirmed malware on critical systems
- Attempted unauthorized access to sensitive data
- DDoS attack affecting availability
- Significant vulnerability with active exploits
- Response: Engage CIRT, manager notification, work until contained

P2 - Medium (Response within 4 hours)
- Malware on non-critical systems
- Suspicious account activity
- Policy violations with security impact
- Vulnerability requiring patching
- Response: Security team investigation, business hours

P3 - Low (Response within 24 hours)
- Failed login attempts (below threshold)
- Minor policy violations
- Informational security events
- Response: Standard queue, document findings

Classification Factors:
1. Data confidentiality impact (PHI, PII, financial, IP)
2. System availability impact (revenue, operations)
3. Data integrity impact (corruption, unauthorized changes)
4. Number of affected systems/users
5. Regulatory reporting requirements

5. Vulnerability Prioritization

When to use: Prioritizing vulnerability remediation

Framework: Enhanced CVSS with business context

Base CVSS Score × Business Context Multiplier = Priority Score

CVSS Severity Ranges:
- Critical: 9.0-10.0
- High: 7.0-8.9
- Medium: 4.0-6.9
- Low: 0.1-3.9

Business Context Multipliers:
- Internet-facing production system: 2.0×
- Internal production system: 1.5×
- Systems with sensitive data: 1.5×
- Development/test environment: 0.5×
- Active exploit in the wild: 2.0×
- Compensating controls in place: 0.7×

Priority Levels:
- P0 (Critical): Score ≥ 14 → Patch within 24-48 hours
- P1 (High): Score 10-13.9 → Patch within 7 days
- P2 (Medium): Score 6-9.9 → Patch within 30 days
- P3 (Low): Score < 6 → Patch within 90 days or accept risk

Additional Considerations:
- Can the system be isolated/segmented?
- Are there effective detective controls?
- What is the patching complexity/risk?
- Is there a vendor patch available?

6. Third-Party Risk Assessment

When to use: Evaluating security risks of vendors and partners

Assessment Framework:

1. Categorize Vendor Risk Level

Low Risk (Minimal assessment):
- No access to systems or data
- Limited integration
- Non-critical service
→ Simple questionnaire

Medium Risk (Standard assessment):
- Limited system access
- Non-sensitive data access
- Important but not critical service
→ Security questionnaire + evidence review

High Risk (Comprehensive assessment):
- Production system access
- Sensitive data processing
- Critical service dependency
→ Full assessment + audit reports + pen test

Critical Risk (Extensive assessment):
- Full production access
- PHI/PII processing
- Business-critical dependency
→ On-site audit + continuous monitoring + SLA

2. Assessment Components

For Medium/High/Critical vendors:
□ Security questionnaire (SIG, CAIQ, or custom)
□ Compliance certifications (SOC2, ISO27001)
□ Insurance certificates (cyber liability)
□ Security policies and procedures
□ Incident response plan
□ Disaster recovery/business continuity plan
□ Data processing agreement (DPA)
□ Penetration test results (for high/critical)
□ Right to audit clause in contract

3. Ongoing Monitoring

4. Vendor Risk Score

Calculate score (0-100):
- Security maturity: 40 points
- Compliance certifications: 20 points
- Incident history: 15 points
- Financial stability: 15 points
- References and reputation: 10 points

Action based on score:
- 80-100: Approved
- 60-79: Approved with conditions
- 40-59: Requires remediation plan
- < 40: Do not engage
