Digitalization is radically transforming the large-scale retail sector (GDO). The adoption of smart devices such as next-generation Points of Sale (PoS), smart scales, and automated lockers has improved efficiency and the customer experience. However, this technological revolution has introduced new cybersecurity challenges. Smart devices, connected to corporate infrastructures and global networks, represent an ever-expanding attack surface, exposing retail companies to potential breaches. ISGroup, with its expertise in the cybersecurity sector, offers advanced solutions to protect retail infrastructures and ensure the security of smart devices.

Technological Innovation in the Retail Sector

Smart devices: opportunities and cybersecurity risks

New smart devices are changing the face of the retail industry, simplifying operations such as order management, payments, and logistics. Examples include:

• Next-generation Points of Sale (PoS): Integrated systems that accept digital payments and manage customer data.
• Smart scales: Connected devices that can calculate prices based on real-time weights and updated data.
• Smart lockers: Automated cabinets for the self-service delivery of products purchased online.

Although these tools improve operational efficiency, their connectivity makes them vulnerable to threats such as:

• Malware attacks that compromise PoS devices.
• Unauthorized access to sensitive customer data.
• Device tampering to alter transactions or disrupt services.

The retail attack surface

With the increase in digitalization, retail infrastructures have become complex ecosystems. Their attack surface includes:

• Internal networks and connected devices.
• Digital payment systems and customer data.
• IoT devices used to manage logistics operations.

Every connected device or endpoint represents a potential vulnerability. Without adequate security controls, a single compromise can propagate throughout the entire corporate network.

ISGroup’s cybersecurity services for the retail sector

ISGroup offers a range of solutions to identify, mitigate, and prevent vulnerabilities in smart devices and retail digital infrastructures.

Discovery: understanding what is public

The first step to protecting smart devices is identifying what is public and accessible. The discovery service includes:

• Mapping of exposed endpoints.
• Risk assessment associated with each connected device.
• Identification of misconfigurations that can increase vulnerability.

Design Review: design analysis

ISGroup analyzes device implementation to ensure they adhere to security principles. The activity focuses on:

• Authentication and authorization mechanisms.
• Management of credentials and access tokens.
• Compliance with industry standards, such as PCI DSS for payment systems.

Secure Code Review: code review in cybersecurity

The code of smart devices is analyzed to identify vulnerabilities such as:

• Hardcoding of credentials or access keys.
• Input handling errors that can lead to malicious code injection.
• Exposure of unnecessary sensitive data.

This activity allows for the identification of issues that would not emerge in dynamic tests, improving security at the root.

Devices Penetration Testing (PT)

ISGroup performs attack simulations on smart devices to evaluate their resilience. Tests include:

• Exploitation of known and unknown vulnerabilities.
• Attempts at unauthorized access to devices and data.
• Verification of the robustness of implemented security measures.

Best practices for retail cybersecurity

To ensure the security of smart devices and retail infrastructures, ISGroup recommends adopting the following best practices:

Authentication and authorization

• Use standard protocols like OAuth 2.0 to manage device access.
• Implement multi-factor authentication (MFA) to protect administrative accounts.
• Restrict device access based on the principle of least privilege.

Data management

• Apply encryption to protect data in transit and at rest.
• Limit data collection to what is strictly necessary.
• Implement retention policies to delete data that is no longer useful.

Monitoring and response

• Integrate a Security Operation Center (SOC) to monitor suspicious activity.
• Perform regular vulnerability assessments to keep defenses updated.
• Develop and test incident response plans to react quickly to attacks.
