Financial Services Security for Legacy Banking Systems
Protect sensitive financial data, ensure PCI DSS compliance, and defend against ransomware with FileSure
Legacy Banking Systems Security Challenges
Financial institutions face sophisticated cyber threats targeting customer financial data, transaction systems, and legacy infrastructure that powers critical operations.
Legacy Financial Systems at Risk
The financial services industry relies on many legacy Windows applications for core banking, trading platforms, and customer management systems. These systems often contain irreplaceable functionality that cannot be easily migrated.
Ransomware groups specifically target financial institutions due to the critical nature of their data and potential for high-value payouts, with attacks increasing by over 200% in the past two years.
- Core banking platforms with limited security controls
- Trading and investment management systems
- Custom financial applications on outdated operating systems
- Branch operations software with direct customer data access
Regulatory Compliance Requirements
Financial institutions must adhere to stringent regulations that mandate specific security controls:
- PCI DSS compliance for credit card data protection
- GLBA requirements for customer information safeguards
- Detailed audit trails for all financial data access
- Strict access controls on customer financial records
- Transaction monitoring and fraud prevention
Regulatory penalties for non-compliance can reach millions of dollars, in addition to reputational damage and loss of customer trust.
FileSure's File-Level Banking Protection
ByStorm Software's FileSure product line provides security solutions tailored for financial institutions that protect customer data and transaction systems through innovative file system security.
Transaction System Protection
FileSure intercepts file operations at the system level, allowing you to monitor and control how financial transaction files are accessed, modified, or deleted.
This prevents malware from compromising transaction records and provides a critical layer of protection for core banking systems.
Financial Data Access Control
Implement granular rules that restrict financial data access based on program identity, ensuring that only authorized applications can access sensitive customer information.
For example, create policies that permit only your approved financial applications to read or modify customer financial records, blocking access from all other programs.
Detailed Audit Capability
Track all financial data access attempts with comprehensive logs that record who accessed data, which application was used, and what actions were performed.
These audit trails provide the documentation needed for regulatory compliance and help investigators trace potential security incidents.
Ransomware Prevention
Block unauthorized executables from running on your financial systems by implementing rules that prevent program files (*.exe, *.dll, etc.) from being written or modified.
This creates a powerful defense against ransomware targeting financial data, even on legacy systems where traditional anti-virus solutions are ineffective or cannot be installed.
Payment Card Data Protection
Secure payment card processing environments by controlling file operations and preventing unauthorized access to customer payment information.
FileSure helps maintain PCI DSS compliance by restricting file access to only authorized payment applications and providing detailed audit logs of all access attempts.
Flexible Deployment Options
Choose the deployment model that best fits your financial institution's size and IT resources:
- FileSure Defend for enterprise financial institutions
- FileSure Cloud for smaller financial services firms
- FileSure for MSPs for outsourced security management
