RFID technology is essential to supply chain workflows. By enabling real-time visibility and seamless data exchange, businesses can operate at incredible speeds. However, supply chains are becoming increasingly connected, making every feature of this innovation vulnerable to cybersecurity risks.
RFID technology is becoming increasingly useful in today’s supply chains, increasing operational efficiency by automating various processes. RFID can improve productivity for businesses with its ability to read data without line of sight and capture it in real time. As a result, many industries are integrating such systems into their supply chain frameworks.
This technology has contributed more than $1.3 billion in revenue across the manufacturing and services supply chain. This revenue spike is due to the innovation’s ability to drive faster fulfillment, optimized inventory levels, and improved tracking accuracy.
However, as RFID systems become more widespread, businesses are at risk of data breaches and many other issues. These threats can negate the benefits of RFID.
The importance of cybersecurity in RFID systems
As RFID is integrated into more operations in the supply chain, new security risks are emerging that companies must pay attention to. These systems continuously collect and transmit data across multiple points in the supply chain. This connectivity makes it a prime target for cyberattacks. Without proper safeguards, vulnerabilities can disrupt critical operations.
Supply chain threats have proliferated in recent years, surpassing CEO fraud as one of the top cybersecurity concerns. It aims to exploit weaknesses in interconnected systems to allow hackers to infiltrate vendor systems and gain access to the infrastructure. Because RFID is critical to tracking goods across global supply chains, attackers view these systems as attractive entry points for data manipulation.
One serious incident occurred in 2020. Attackers infected up to 18,000 businesses with malware through a software supplier they all use. This incident illustrates the complexity of cyberattacks and makes it even more important to work closely with vendors and implement best practices to prevent cyberattacks.
RFID-enabled supply chain cybersecurity challenges and solutions
Despite the many benefits of RFID technology, it also poses risks that supply chain managers need to address immediately.
1. Data Interception and Eavesdropping. Because RFID systems communicate between tags and readers, malicious attackers can potentially intercept this data. They can eavesdrop on unencrypted signals and gain access to sensitive information such as shipping schedules and customer data. Recovering this could result in significant financial loss and reputational damage.
The best way to prevent eavesdropping is to adopt a layered security approach that prioritizes encryption and secure authentication protocols. Managers must ensure that all RFID systems in the supply chain use end-to-end encryption to protect transmitted data. If encryption is in place, even if an attacker intercepts the signal, they will not be able to read the code.
2. Cloning and spoofing attacks. Cloning and spoofing are increasing threats to RFID-enabled supply chains. In a cloning attack, a malicious attacker creates an identical copy of a legitimate RFID tag. This counterfeit product can then be used to bypass authentication systems and insert unauthorized goods into the supply chain.
Conversely, spoofing involves manipulating an RFID reader to accept false information from a malicious tag. This method allows hackers to tamper with shipping data or enter restricted areas. Both threaten operations and pose risks such as loss of revenue.
However, supply chain management can reduce this risk by implementing cryptographic authentication protocols. This strategy makes cloning and spoofing deployments extremely difficult. By giving these tags a cryptographic key, companies can ensure that each tag is unique and difficult to duplicate.
3. Denial of Service Attack. RFID systems are vulnerable to denial of service (DoS) attacks by disrupting communication between tags and readers. Malicious attackers can overwhelm these two with excessive data requests and signal interference. As a result, the reader is unable to process legitimate tag data, creating an operational bottleneck.
Therefore, it is important to build in system redundancy and implement traffic management protocols. Redundancy allows a backup system to take over if one reader becomes overloaded, minimizing downtime.
4. Replay attacks. Replay attacks allow an attacker to intercept communications between an RFID tag and a reader, record data, and replay it later to gain access to or manipulate the system. Since the system assumes that the reproduced data is genuine, it can be used to authorize fraudulent transactions or introduce counterfeit goods.
To prevent these, supply chain managers must implement time-based authentication protocols. These allow tags and readers to generate unique, time-sensitive codes for each transaction. When the intercepted signal is played back later, the system recognizes the expired code and refuses to send it.
5. Disposal or Reuse of Unsecure RFID Tags. RFID tags contain valuable data that can be exploited by malicious actors if improperly handled at the end of their lifecycle. Discarding tags in supply chain operations without deactivating or erasing them can potentially expose sensitive information. Similarly, reusing tags without proper reconfiguration can lead to data leaks.
To mitigate these risks, supply chain managers must adopt safe disposal protocols that enforce proper deactivation or reconfiguration. Disabling a tag makes it useless. However, brands may also physically destroy it if it contains highly sensitive information.
If a company plans to reuse tags, it is essential to reset and reconfigure each tag before redeploying. This process removes data left over from previous usage and eliminates the risk of data leakage.
RFID-enabled supply chain protection
RFID technology improves supply chain efficiency and accuracy, but it also comes with cybersecurity risks that managers often overlook. Cybersecurity vulnerabilities threaten business continuity, so strategic planning and proactive measures are essential.
When security becomes an integral part of your RFID strategy, businesses can feel confident about their future.
