Let’s apply the Business Impact Analysis (BIA) process to a financial company while aligning it with CISSP principles. A financial institution, such as a bank or investment firm, is highly dependent on secure and continuous operations due to the sensitive nature of financial transactions, regulatory requirements, and customer trust.

Business Impact Analysis (BIA) for a Financial Company (CISSP-Aligned)

1. Identify Critical Functions and Resources

The first step is to identify the mission-critical business functions and the associated resources that support them.

Critical Business Functions:

• Online Banking System – Customers rely on 24/7 access to their accounts.
• Payment Processing (Credit/Debit Transactions, Wire Transfers, ACH) – Must process transactions in real time.
• Trading & Investment Platform – Delays or outages can cause financial losses.
• Customer Support & Call Centers – Required for fraud prevention and transaction disputes.
• Compliance & Regulatory Reporting – Failure to report could lead to legal penalties.

Key Dependencies:

• IT Infrastructure (Servers, Databases, Cloud Services)
• Cybersecurity Tools (Firewalls, SIEM, IDS/IPS, DLP)
• Third-Party Payment Gateways & Clearinghouses
• Financial Data Feeds (Stock Market, Exchange Rates)
• Regulatory Bodies (SEC, FINRA, GDPR, PCI DSS Compliance)

2. Assess Impact of Disruptions

A Business Impact Analysis must evaluate the effects of disruptions on these critical functions. The financial company determines:

Key Metrics:

• Recovery Time Objective (RTO): How long a function can be down before severe damage occurs.
• Recovery Point Objective (RPO): Maximum data loss tolerance in case of a failure.
• Maximum Tolerable Downtime (MTD): The longest period an outage can last before the business is unsustainable.

Business Function	Impact of Disruption	RTO	RPO	MTD
Online Banking System	Customer dissatisfaction, reputational damage, potential regulatory fines	1 hour	5 minutes	4 hours
Payment Processing	Failed transactions, financial losses, regulatory non-compliance	15 minutes	1 minute	1 hour
Trading Platform	Customer loss, lawsuits, regulatory penalties	30 minutes	5 minutes	2 hours
Compliance Reporting	Legal consequences, heavy fines	8 hours	30 minutes	24 hours
Customer Support	Customer trust issues, fraud escalation	2 hours	30 minutes	6 hours

3. Identify and Analyze Threats & Risks

Now, we analyze potential risks to the confidentiality, integrity, and availability (CIA Triad) of financial operations.

Threats:

1. Cybersecurity Attacks – DDoS, ransomware, insider threats.
2. System Failures – Database corruption, software bugs.
3. Third-Party Risks – Vendor outages affecting payment processing.
4. Natural Disasters – Data center damage due to earthquakes, floods.
5. Regulatory Non-Compliance – GDPR, PCI DSS, SOX violations.

Risk Analysis Example:

• Threat: Ransomware attack encrypts the bank’s transaction database.
• Impact: Customers cannot access funds, major reputational damage.
• Mitigation: Encrypted backups, multi-layered security, endpoint protection.

4. Develop Recovery Strategies

The company must implement strategies to minimize downtime and recover quickly.

Business Function	Recovery Strategy
Online Banking System	Active-Active Redundancy across multiple data centers
Payment Processing	Load Balancing & Failover Systems
Trading Platform	Real-time Replication & Disaster Recovery Site
Compliance Reporting	Automated Cloud Backup & Legal Audits
Customer Support	Remote Work Capabilities & Cloud-Based Call Centers

5. Document Findings and Communicate with Stakeholders

A formal BIA Report is created and shared with executives, IT teams, and compliance officers. The report includes:

• Risk Analysis Results
• Financial and Operational Impact Assessment
• Recommended Mitigation Strategies
• Testing & Training Plans

6. Test, Review, and Update the BIA Regularly

Since threats evolve, the BIA must be continuously tested and updated.

Testing Methods:

1. Tabletop Exercises – Simulated cyberattack on banking infrastructure.
2. Disaster Recovery Drills – Failover tests for online banking.
3. Incident Response Simulations – Ransomware response readiness.

Conclusion

For a financial company, Business Impact Analysis (BIA) ensures that disruptions are minimized, regulatory compliance is maintained, and customer trust is protected. This CISSP-aligned approach provides a structured way to assess risks and implement security controls.
