- 3. Create policies and procedures
- 4. Implement controls
- 5. Train employees
Stage 2:
- 6. Internal audit (find gaps)
- 7. Management review
- 8. Hire external auditor (certification body)
- 9. Stage 1 Audit: Documentation review
- 10. Stage 2 Audit: On-site verification
Ongoing:

Definition
Auditing for Service Providers
Cloud companies, SaaS
Publisher
AICPA
American Institute of CPAs
Focus: Five "Trust Service Principles"
- β Security: Protection against unauthorized access
- β Availability: System available for operation and use
- β Processing Integrity: System processing is complete, valid, accurate, timely
- β Confidentiality: Confidential information protected
- β Privacy: Personal information collected, used, retained, disclosed per privacy notice
Types:
SOC 2 Type I:
- Describes systems/controls at specific point in time
- Auditor opinion: "Are controls suitably designed?"
- Faster, cheaper (3-6 months)
SOC 2 Type II:
- Evaluates controls over period of time (6-12 months)
- Auditor opinion: "Are controls operating effectively?"
- More rigorous, preferred by customers
Who Needs It:
Needs SOC 2:

Cost: $20,000 - $100,000+ annually
C. Other Important Standards:
NIST Cybersecurity Framework (CSF):
- US government standard
- 5 Functions: Identify, Protect, Detect, Respond, Recover
- Voluntary but widely adopted
COBIT (Control Objectives for Information Technologies):
- IT governance framework
- Aligns IT with business goals
ITIL (Information Technology Infrastructure Library):
- IT service management
- Focuses on operations, not security
4Audit & Assessment
How do you prove you are compliant? You get audited.
A. Security Audits Γ°ΕΈβΒ
Definition: A systematic evaluation of the security of a company's information system by measuring it against a set of established criteria.
Types:
Internal Audit:
- Conducted by your own employees
- Goal: Find issues early (before external audit)
- Frequency: Quarterly or semi-annually
Benefits:
- No cost (internal resources)
- Safe to fail (fix before real audit)
- Continuous improvement
External Audit:
- Conducted by independent third party
- Goal: Certify compliance (ISO 27001, SOC 2)
- Frequency: Annually (or per certification requirement)
Benefits:
- Objective assessment
- Customer confidence
- Legal validity
Audit Process:
1. Planning:
- Define scope (which systems, locations, time period) - Select standards (ISO 27001, PCI-DSS, etc.) - Assemble audit team - Schedule interviews
2. Fieldwork:
- Review documentation (policies, procedures) - Conduct interviews (employees, IT staff, management) - Test controls (sample transactions, access logs) - Observe physical security
3. Reporting:
- Findings: What's working, what's not - Recommendations: How to fix issues - Risk ratings: Critical, High, Medium, Low - Timeline: Remediation deadlines
4. Follow-Up:
- Track remediation progress - Verify fixes implemented - Close findings
B. Compliance Assessment β
Definition: A review to determine if the organization meets specific regulatory requirements.
Goal: To answer "Are we following the law?"
Scope:
- β Regulatory: GDPR, HIPAA, CCPA compliance
- β Contractual: Meeting SLA security requirements
- β Industry: PCI-DSS, SOC 2
Deliverable:
- Compliance score (% of requirements met)
- Non-compliance findings
- Remediation plan with costs and timeline
C. Risk Assessment β οΈ
Definition: Identifying potential threats (e.g., "What if our server burns down?").
Process:
1. Asset Identification:
Inventory: Servers, databases, laptops, paper files Value: What's the business impact if lost/stolen?
2. Threat Identification:
Natural: Fire, flood, earthquake Human: Hackers, insiders, competitors Technical: Hardware failure, software bugs
3. Vulnerability Assessment:
Scan systems for weaknesses Review configurations Test security controls
4. Risk Analysis:
Likelihood: How probable is this threat? Impact: How much damage would it cause? Risk = Likelihood Γ Impact
5. Risk Treatment:
Accept: Live with risk (low impact/likelihood) Mitigate: Implement controls (most common) Transfer: Insurance (for high-cost events) Avoid: Eliminate the activity (extreme cases)
D. Gap Analysis π
Definition: Comparing where you are versus where you need to be.
Example:
Requirement: GDPR Article 32 - "Implement encryption" Current State: Database stored in plain text Gap: No encryption implemented Remediation: Deploy AES-256 encryption (cost: $10K, time: 2 months)
Gap Analysis Matrix:
| Control | Required | Current | Gap | Priority | Cost | Timeline |
|---|---|---|---|---|---|---|
| Encryption | Yes | No | GAP | High | $10K | 2 months |
| MFA | Yes | Partial | GAP | Medium | $5K | 1 month |
| DLP | Recommended | No | Gap | Low | $20K | 6 months |
| Firewall | Yes | Yes | OK | - | - | - |
Prioritization:
- β Critical gaps: Legal requirement + high risk
- β High gaps: Legal requirement + medium risk
- β Medium gaps: Best practice + high risk
- β Low gaps: Best practice + low risk
Critical Comparison
β οΈ Compliance vs. Security (The Reality Check)
| Feature | Compliance | Security |
|---|---|---|
| Goal | Passing an Audit | Protecting Data |
| Driver | External (Government/Laws) | Internal (Business needs) |
| Scope | Checkbox-based ("Do you have a firewall?") | Risk-based ("Is the firewall actually working?") |
| Reality | You can be Compliant but NOT Secure | You can be Secure but NOT Compliant |
| Motto | "Did we follow the rules?" | "Are we safe from hackers?" |
| Timeline | Annual audit cycle | Continuous monitoring |
| Focus | Documentation (policies, procedures) | Implementation (actual defense) |
| Penalty | Fines, lawsuits | Data breach, reputation loss |
The Danger:
Compliant but Insecure Example:
β Company has firewall (compliant)
β Firewall misconfigured, allows all traffic (insecure)
β Company passes audit (auditor sees firewall exists)
β Company gets hacked (firewall didn't protect)
The Ideal:
Compliance + Security = True Protection
β Meet legal requirements (avoid fines)
β Implement effective controls (prevent breaches)
β Continuous improvement (adapt to new threats)
Conclusion
Compliance is the baseline. While regulations like GDPR and HIPAA force organizations to implement minimum security standards, they are not a silver bullet against hackers.
True cybersecurity goes beyond checking boxes for an auditor; it involves a continuous culture of risk management and defense.
Key Takeaways:
- β Regulations are mandatory (GDPR, HIPAA, PCI-DSS) - fines for non-compliance
- β Standards are voluntary (ISO 27001, SOC 2) - competitive advantage
- β Audit cycle: Risk Assessment β Gap Analysis β Remediation β Audit
- β Compliance β Security (you can pass audit but still get hacked)
- β GDPR: β¬20M or 4% revenue fines, 72-hour breach notification
- β HIPAA: $50K per violation, criminal penalties possible
- β PCI-DSS: Encrypt card data, never store CVV, quarterly scans
- β ISO 27001: 93 controls, PDCA cycle, 3-year certification
- β SOC 2: Trust principles, Type I vs Type II, annual renewal
- β Gap analysis: Compare current vs required, prioritize remediation
The Future: AI-powered compliance monitoring, automated evidence collection, continuous auditing, and blockchain-based audit trails will transform compliance from annual checkpoints to real-time assurance! πβ
