Financial institutions hold the personal, commercial, and payment data that cybercriminals value, while customers expect access to their money and services at all times. A single compromised account or unavailable platform can cause financial loss, regulatory scrutiny and lasting reputational damage.
Preparation has to cover more than security software. Firms need to know which services matter most, control access carefully, test their response plans and ensure suppliers meet the same standards. The following measures can help financial organisations reduce exposure and recover more quickly when an incident occurs.
Start with the systems that matter most
Map the technology, data and external services your organisation depends on. This exercise should identify where sensitive information is stored, who can access it and which operational processes would stop if a system became unavailable. Include less obvious dependencies such as identity providers, cloud-based document platforms and automated payment connections.
Rank each asset according to its operational importance and the possible effect of compromise. A customer account platform needs tighter controls and faster recovery arrangements than an internal booking tool. The same principle applies to data. Login credentials, account details and identity records require stricter handling than publicly available marketing material.
The global cyber threat affects the wider financial system because institutions, technology providers and market infrastructure are closely connected. An incident at one organisation can disrupt services elsewhere, so your assessment should examine dependencies beyond your own network.
Keep an up-to-date asset register that records system owners, software versions, data categories and recovery priorities. Review it after mergers, platform changes and new supplier appointments. A forgotten server or unmonitored cloud account can create an opening even when core systems are well protected.
Once priorities are clear, direct security spending towards the systems where interruption or data loss would cause the greatest harm.
Strengthen everyday access controls
Many incidents begin with stolen login details, an unpatched device or access that was never removed when somebody changed roles. Addressing these routine weaknesses can produce a greater reduction in risk than buying another isolated security product.
Require multi-factor authentication for email, remote access, cloud services and administrative accounts. Wherever possible, use authentication apps, passkeys or physical security keys because they offer stronger protection than text messages. Apply the principle of least privilege so employees can reach only the systems and data required for their current duties.
Financial firms without enough internal capacity may benefit from specialist IT support for financial services that covers data protection, compliance support, system reliability and resilience improvement. The provider should be able to explain how it monitors threats, applies security updates, and escalates urgent events.
Access reviews also need a fixed schedule. Managers should confirm permissions at least quarterly and immediately after an employee leaves or moves into another position. Administrative access deserves closer scrutiny because one compromised privileged account may expose multiple systems.
Train people with realistic scenarios
Employees need practical guidance that reflects the messages and requests they receive during an ordinary working day. Generic annual courses often fail because the examples feel remote from real tasks. Use short sessions based on situations such as an apparent customer requesting an urgent account change, a senior manager asking for confidential files, or a supplier sending revised payment instructions.
Training should explain how to check a request through a separate channel. If an employee receives an unexpected message from a colleague, they can call a known number or start a new conversation through an approved company system. Staff should never rely on the contact details contained in the suspicious message itself.
Create a simple reporting route, such as a button within the email service or a dedicated internal number. Employees are more likely to report a possible incident when the process takes seconds, and they know they won’t be blamed for raising a false alarm. Early reporting gives the security team time to block malicious domains, reset credentials, and warn other colleagues.
Senior leaders should take part in the same exercises. Their accounts often have broad access and criminals may use their names to pressure staff into bypassing normal checks.
Measure results through reporting rates and response times, not only test failure rates. A useful programme shows that staff recognise suspicious activity sooner and know exactly where to send it.
Prepare for disruption before it happens
An incident response plan should tell people what to do during the first hour, the first day and the recovery period. Assign named owners for technical investigation, legal assessment, regulatory communication, customer support and media enquiries. Record deputies as well, since the primary contact may be unavailable.
Plans work only when teams practise them. Run a tabletop exercise using a credible scenario, such as employees losing access to customer records on a busy weekday. Ask participants how they would confirm the scope, maintain critical services, and decide which groups need updates. The exercise will expose missing contact details, unclear authority, and assumptions that haven’t been tested.
The effect of cybersecurity risks extends into operational continuity and reputation, so communications must form part of the response. Prepare adaptable messages for employees, customers, suppliers and regulators. These should be accurate and should avoid promising a recovery time before technical teams have enough evidence.
Keep response documents somewhere accessible if the main network is unavailable. Key personnel should have secure offline copies of contact lists, service priorities and escalation procedures.
Independent knowledge can also sharpen internal planning. The account of national cyber defence expertise illustrates why collaboration and specialist input matter when institutions are preparing for risks that cross organizational boundaries.
Test backups and recovery procedures
Backups have limited value unless the organisation can restore them within the time required by the business. Define recovery time objectives for each critical service and recovery point objectives for the maximum acceptable amount of lost data. A payment platform may need much faster restoration than an archive containing older documents.
Maintain multiple backup copies and separate at least one from the main production environment. Restrict access to backup administration and monitor attempts to change retention settings or delete stored copies. If the same account controls live systems and backups, one compromised identity could affect both.
Schedule restoration tests throughout the year. Select a sample of systems, rebuild them in an isolated environment, and verify that applications work and records remain complete. Record the actual recovery time, then compare it with the target. If a service with a four-hour target takes two days to restore, the gap requires technical changes or a revised continuity plan.
Testing should cover people and procedures as well as data. The team needs to know who authorises restoration, which system comes back first, and how users confirm that information is accurate.
After each exercise, assign every improvement to a named person with a deadline. This turns recovery planning into an ongoing operational process instead of a document that receives attention only during an audit.
Treat suppliers as part of your security boundary
Financial institutions often rely on software vendors, cloud platforms, data processors and outsourced operational services. Each connection can affect availability or expose information, so supplier checks should begin before a contract is signed and continue throughout the relationship.
Ask potential providers how they manage access, apply updates, protect backups and notify customers of incidents. Contracts should define reporting times, data handling requirements, and your right to request evidence of security testing. Broad claims about high standards aren’t enough. Look for recent assessment results, clear control ownership and proof that recovery procedures have been exercised.
Preparation for coordinated cyberattacks also requires communication across organisational lines. Agree on named contacts and escalation channels before an urgent event. If a key service fails outside office hours, your team should know whom to call without searching through old contracts or support portals.
Segment supplier access so a provider can reach only the systems needed to deliver its service. Time-limit temporary accounts and review permanent connections regularly. When a contract ends, remove integrations, credentials and stored data according to a documented exit process.
Cyber readiness becomes measurable when responsibilities, recovery targets and evidence are clear. The strongest final check is a live exercise involving a critical supplier, because it reveals whether both organisations can exchange accurate information and restore the service within the agreed timeframe.
