Cyber Resilience Checklist: Financial Services
A guide to help you assess your financial institution’s readiness for a serious cyber event.
Can Your Financial Institution Survive a Major Cyber Incident?
Cyber incidents are inevitable — and potentially disruptive for financial institutions because every day without full recovery causes reputational harm. Unfortunately, 76% of organizations take longer than 100 days to recover from a breach.1
That’s why you need confidence in your cyber resilience. Use this checklist to discover the steps you should take to ensure your technology, people and processes can help you prevent systemic impact, maintain liquidity and avoid regulatory penalties.
Five Steps to Cyber Resilience for Financial Institutions
Identify Minimum Viability for Financial Operations
Understand the core financial systems and services you must keep running or restore first when a cyber incident occurs.
- Have you identified the core operations — such as banking ledgers, wholesale payment processing (e.g., ACH, Fedwire) and trading platforms — required to stay solvent during a major breach?
- Are your recovery time objective (RTO) and recovery point objective (RPO) metrics strictly aligned with critical market functions such as end-of-day settlement deadlines?
- When an incident occurs, can you focus your recovery effort on critical capital markets and retail banking infrastructure before back-office or administrative services?
Map Dependencies and Recovery Paths
Many institutions struggle during an outage because they lack visibility into the upstream systems required to bring critical financial applications back online.
- Do you have comprehensive application dependency mapping that details the specific connections for core banking ledgers, SWIFT messaging gateways or trading platforms?
- Have you pinpointed the upstream data sources — such as real-time market data feeds, clearinghouse integrations or customer identity directories — that must be restored first?
- Do you maintain an alternative recovery environment to rigorously test recovery runbooks and validate how missing dependencies impact crucial financial workflows?
Build Resilience Across People, Processes and Technology
Cyber resilience extends far beyond IT infrastructure — operational fragility often stems from human factors and rigid workflows, particularly during high-stress market events or severe breaches.
- Have you assessed how effectively your incident response, risk management and front-office teams can execute critical operations under the pressure of a cyber incident?
- Have you reviewed whether highly optimized, automated processes — such as straight-through processing (STP), automated clearing or algorithmic trading — can handle a shock?
- Are your operational resilience plans isolated within individual business units or coordinated holistically to protect the entire institution?
Restore Trustworthiness and Data Integrity
Cyber recovery extends beyond simply restoring IT functionality. You must guarantee the integrity, usability and security of financial data so trading, core banking and customer operations can safely resume.
- Do you employ robust data protection controls such as immutable snapshots, air-gapped cyber vaults or write-once, read-many (WORM) storage?
- Can you rigorously validate that recovered environments, such as payment gateways or trading platforms, are thoroughly sanitized and free of dormant malware?
- Do you have strict reconciliation processes in place to ensure that recovered data is accurate, completely up-to-date and free from unauthorized alterations?
Make Resilience an Institution-Wide Program
Cyber resilience must be an ongoing, programmatic effort guided by strict regulatory frameworks and automated to minimize market disruption.
- Have you implemented a repeatable recovery improvement lifecycle tailored to evolving financial threats rather than relying on static, compliance-driven disaster recovery plans?
- Can you leverage automation to proactively quarantine compromised banking systems, initiate failovers and rapidly rebuild trading infrastructure during the stress of a breach?
- Do you have a plan to manage complexity and cost with managed security service providers (MSSPs) or Disaster Recovery as a Service (DRaaS) tailored specifically for financial institutions?
