In an era where digital transformation drives innovation, securing sensitive data has become a non-negotiable priority for businesses, especially given the constant emergence of sophisticated cyber threats. As cyber attacks grow increasingly sophisticated, traditional security approaches are no longer sufficient to prevent unauthorised access. For B2B ecosystems that rely on seamless file transfers, adopting a Zero Trust approach to security is critical to mitigating risks like lateral movement and ensuring data integrity even when dealing with external parties and potential unauthorised users.

IBM’s Sterling File Transfer solution empowers enterprises to secure file transfers and reinforce their Zero Trust security frameworks, ensuring that intellectual property and other sensitive data remains protected in transit and at rest both during inbound and outbound file transfers, even when accessed via remote access or mobile devices. In this article we focus on why it’s more important than ever to keep security your number one priority when it comes to file transfers and how the Sterling File Gateway, secure web gateway (Secure Proxy), and Control Center monitoring security capabilities within the Sterling Secure File Transfer solution address the many security concerns businesses have to pay attention to in today’s digital world, including those related to cloud infrastructure and maintaining a positive user experience.

What is Zero Trust in a B2B Context?
The Zero Trust security model operates on the principle of “never trust, always verify.” Unlike traditional models that assume users or systems inside the secure perimeters of corporate networksare safe, Zero Trust continuously validates every access request (i.e., access to transfer a file), according to specific configuration details and established trust policies and business policies. This is especially crucial when considering Third party access and external access to your private network.

For B2B data exchanges, this means:

1. Authentication at Every Step: Every user, system, or application must authenticate before accessing or transferring files, regardless of their level of access.

2. Granular access controls: Permissions are granted on a need-to-know basis, reducing the attack surface and limiting potential damage from compromised accounts.

3. End-to-End Encryption: Data is encrypted during transfer and at rest to prevent unauthorised access and protect against eavesdropping. This is vital whether data resides on-premises or in a cloud service or the public cloud.

4. Continuous Monitoring: All file transfer activities are logged and monitored in real time for suspicious behavior, with comprehensive audit trails maintained for accountability and analysis of potential security incidents.

Challenges in Securing B2B File Transfers B2B file transfers involve exchanging sensitive information—financial data, customer records, supply chain updates—between multiple stakeholders. This complexity introduces significant challenges, particularly concerning cloud security and the management of diverse systems.

1. External Threats: Threat actors frequently target vulnerable file transfer protocols to intercept or manipulate data, posing significant risks to critical infrastructure and sensitive information. Understanding different types of attacks is crucial for effective defense.

2. Internal Risks: Insider threats or misconfigurations can lead to data breaches, emphasizing the need for robust internal controls and adherence to security best practices in file management.

3. Regulatory compliance: Industries like healthcare (HIPAA), finance (PCI DSS), and retail (GDPR) impose strict data protection regulations, requiring organizations to implement stringent security measures for all data exchanges, including those involving external parties.

4. Scalability: As businesses grow, managing secure file transfers across multiple geographies and partners, each with unique requirements and potentially different security frameworks, becomes increasingly difficult, especially when considering the security of application traffic and the need for consistent policy enforcement across the broader network.

How IBM Solutions Support Zero Trust for B2B Data

The IBM Sterling Secure File Transfer solution, with its Sterling File Gateway and Sterling Secure Proxy capabilities, is designed to address these challenges, enabling businesses to implement Zero Trust principles effectively and establish software defined perimeters.

Sterling File Gateway capabilities for ensuring secure and scalable file transfers

• Protocol-Agnostic Security: SFG supports various secure protocols like SFTP, FTPS, and HTTPS, ensuring compatibility with each trading partners' systems while maintaining robust security and facilitating secure communication even with varying partner security postures.

• Encryption and Key Management: Data is encrypted using advanced algorithms, and encryption keys are centrally managed to simplify operations and enhance the security of data at rest and in transit, regardless of whether it's on-premises or in the cloud infrastructure.

• Role-Based Access Controls: Granular access controls limit users’ ability to access or transfer files beyond their roles, minimizing the risk of unauthorised access and potential data leaks.

• High Scalability: SFG handles high-volume file transfers without compromising security, making it ideal for enterprises with extensive partner networks and ensuring consistent security capabilities as data volumes grow.

Sterling Secure Proxy capabilities for safeguarding network edges

• DMZ-Based Security with Session Break: SSP prevents direct connections between external trading partners and internal systems, reducing the attack surface and mitigating the risk of lateral movement into corporate networks.

• In-Flight Virus Scanning: Performs in-memory scanning of incoming files to ensure malware is quarantined at the DMZ layer, protecting internal systems from cyber threats.

• Helps to enforce Data Loss Prevention scanning to ensure no sensitive information leaves your organization during outbound file transfers, safeguarding intellectual property and ensuring regulatory compliance.

• Multi-Factor Authentication (MFA): Adding an extra layer of authentication strengthens access controls and reduces the likelihood of unauthorised users gaining remote access.

Sterling Control Center security monitoring capabilities

• Failed Logins: Easily investigate potential unauthorised access attempts, providing real time visibility into suspicious activity.

• Weak Ciphers: Examine partners connecting with weak ciphers that pose a risk to data transmission security, allowing for proactive remediation to strengthen secure perimeters.

• Virus Scans: See virus scan report summary indicating the presence of potentially harmful software that has been quarantined or removed, contributing to the overall security capabilities.

• Expiring Certificates: Take action on certificates nearing expiry dates, necessitating prompt renewal to maintain secure communications and avoid disruptions to secure file transfers.

• Brute Force Attacks: Identify incidents of repeated login attempts via a brute force attack repository, indicating targeted attacks that must be addressed to protect against unauthorised access.

Why Zero Trust is Essential for Digital-First Businesses

The shift toward digital-first strategies has expanded attack surfaces, making data security more challenging than ever, especially with the increased reliance on cloud infrastructure and mobile devices. Zero Trust principles provide a robust framework to address these challenges by:

1. Minimizing Risks: Limiting access and monitoring all activity ensures vulnerabilities are addressed proactively, reducing the potential impact of cyber attacks.

2. Boosting Partner Confidence: Secure file sharing and robust security measures foster trust with partners and clients, demonstrating a strong commitment to data protection.

3. Enhancing Compliance: A Zero Trust approach aligns with regulatory compliance standards, helping businesses avoid penalties and maintain a strong security posture when dealing with sensitive data and external parties.
