POS (Point-of-sale) transactions make up 51%[1] of retailers’ most valuable data. This data can include average transaction value, sales per category, and sales per employee. Similarly, other industries, such as hospitality, healthcare, and logistics, equipped with Android POS systems are vulnerable to data threats. Given the sensitivity and importance of data security, managing and monitoring Android POS systems is necessary.
In this blog, we will understand the importance of Android POS security, learn about the threats these systems face, and the security features provided by mobile device management (MDM) solutions to safeguard the critical data handled by Android POS systems.
What is an Android POS System?
Android POS system refers to point-of-sale devices powered by the Android operating system. It utilizes Android POS devices such as smartphones or tablets to process transactions, track inventory, manage employee access, and gather customer data. These systems often include payment terminals and self-service kiosks.
Importance of Android POS System Security
Android POS devices provide comprehensive business insights by feeding data to central systems, maintaining financial status, inventory, and sales records, and automating multiple tasks. This ultimately saves businesses time and reduces errors.
POS devices handle sensitive information, including revenue and sales data and customer credit or debit card details. Android is an open-source operating system, so ensuring the security of POS terminals based on Android OS is crucial, as financial losses from sensitive data breaches can be substantial. The black market trade of stolen credit card information has made POS devices, terminals, and environments attractive targets for cybercriminals, posing significant threats to enterprises.
To safeguard against these cyberattacks, businesses must implement strict security measures to harden the POS environment. Protecting sensitive data and maintaining customer trust requires a comprehensive approach to POS security, which can be achieved via a robust mobile device management solution.
Android POS Systems: Security Challenges
1. Data Breach
Point-of-sale systems are highly vulnerable to data breaches due to the vast amount of sensitive data they handle. Some of the common methods that lead to data breaches include:
a. Malware attacks: Malware attacks are often initiated through spear-phishing emails, SQL injections, or exploiting default passwords on devices. This enables cybercriminals to enter various networks, seize admin credentials, and deploy tools like RAM scrapers or network sniffers to extract customer data. This information is then breached via compromised FTP servers or web hosts, causing substantial financial harm and jeopardizing customer trust.
b. Unauthorized access: Weak password combinations and the misuse of USB ports or SD cards facilitate unauthorized access, enabling data manipulation and extraction. This can lead to data theft and financial loss. Confidential information could be transferred and sold for malicious reasons.
c. Public Wi-Fi networks: Public Wi-Fis are unencrypted networks. Using public Wi-Fi networks can expose Android POS devices to data breaches or man-in-the-middle (MITM) attacks, further compromising the security of the information transmitted.
2. Device Theft
Theft of POS systems poses a serious threat to businesses, especially with multiple devices deployed across various locations. Stolen devices can grant unauthorized access to sensitive customer data, potentially leading to data breaches and tarnishing the brand’s reputation.
Businesses must implement robust security measures to protect against physical theft, ensure the integrity of customer information, and safeguard business operations from fraudulent activities.
Key Features of Android POS Security with MDM
1. Policy Enforcement
MDM solutions provide IT admins with the ability to implement security policies such as data encryption and password complexity. Admins can block or disable peripheral devices such as USB ports and prevent SD cards from factory reset, ensuring consistent data security and minimizing data loss. These enforced policies prevent unauthorized access to Android POS devices, safeguarding confidential data and maintaining secure POS operations. Furthermore, MDM solutions allow administrators to control website access by specifying which websites are allowed or blocked, securing POS devices from malicious link attacks.
2. Kiosk Lockdown
Kiosk mode restricts the device to a single-app or multi-app mode. Single-app mode locks the device to a single application and enables admins to block hardware keys and navigation. Alternatively, multi-app mode enables two or more apps on the Android POS device, blocking the rest. For instance, restaurant owners use Android tablets for ordering, and kiosk mode allows for single-app functionality. Retailers can limit access to work-related apps and restrict other applications.
Furthermore, if any POS device undergoes reboot or restart, it will still open in kiosk mode, ensuring allowed apps remain on the screen and cannot be closed or bypassed.
3. Location Tracking and Geofencing
An MDM solution enables administrators to set geofence for Android POS systems and track their locations. If any POS device breaches the geofence, IT admins receive alerts, enabling them to recover the lost or stolen device easily. MDM solutions offer remote wipe and lock features that can be used to prevent data misuse, ensuring the security of sensitive information.
4. Application Management
MDM platforms enable centralized enterprise application management. Administrators can configure, distribute, and update applications to ensure all Android POS devices run the latest, most secure versions. Additionally, MDM solutions allow admins to block unauthorized or potentially malicious apps, maintaining the integrity and security of the Android POS environment.
5. Android OS Updates
Regularly updating the Android POS software is crucial for security. MDM solutions enable the deployment of Android OS updates, a critical capability for maintaining Android POS device security. By scheduling these updates during maintenance windows, administrators can minimize downtime and ensure continuous operation.
6. Mobile Threat Defense
Open Wi-Fi networks are vulnerable to cybercriminals. These threat actors can seize sensitive customer and financial data if an Android POS device is connected to public Wi-Fi networks. An MDM solution integrated with mobile threat defense capabilities can automatically encrypt traffic on these networks, creating a secure tunnel for data transmission. This ensures the sensitive data is scrambled and unreadable to prying eyes, enhancing security in Android POS environments.
