Wireless communications can be intercepted, disrupted, and manipulated due to the nature of wireless. A wired system puts limits on who can access or intercept the communication stream, however if a signal is broadcast wirelessly then anyone with the range can intercept those signals unless the signal is properly encrypted, timestamped, and/or authenticated. Risks from sending data wirelessly without proper encryption may be intercepted communications, tampering with the data being sent, unauthorized access to a network, or even a complete compromise of the system.
If you are a business client dealing in a B2B world, those risks can result in compromised or lost trade secrets worth millions, and potential financial loss in restoring security from a breach with potential legal ramifications for failure to protect the client, in addition to the potential damage to the business reputation. In industries that work with compromised or sensitive information, those risks have even greater consequences, such as healthcare, finance, and defense.
To protect data while transmitting it wirelessly, businesses must take a layered approach to protect data from the device level and up to the organization's policies for network use. Device-level protection is fairly common in modern wireless transmitters. For example, industrial-grade transmitters use an array of encryption technologies like AES 128 or AES 256 encryption standards, and device authentication mechanisms.
Encryption can protect your data, but it cannot be read without the decryption key. By using AES-128 or AES-256, on an industrial-grade transmitter the risk of spoofing or mill-in-the-middle attacks drastically goes down because this encryption technology utilizes an authentication mechanism to verify if the device is legitimate or not.
The use of frequency hopping spread spectrum (FHSS) technology is another important element because it also minimizes the risk of jamming and unauthorized interception because the transmission frequency is always changing. This method of transmission is very beneficial in environments that have multiple wireless systems operating simultaneously, such as large distributors, manufacturing plants, and logistics areas.
As important as the transmitters are, the design of the network architecture also plays a role in supporting the secure transfer of data. Enterprises should design the wireless networks to create a segmentation mindset and isolate critical systems from general-purpose networks. This limits the potential attack surface area, and it also prevents the problem of a single hack compromising the entire infrastructure. We recommend doing this through the use of VLANs for data services, and dedicated wireless access points used exclusively for sensitive operations. This provides another layer of control as well. Firewalls and intrusion detection systems using wireless monitoring tools should be employed to protect environments of concern by pre-emptively flagging satellite activity from unauthorized users before they escalate these into threats.
Additionally, zero-trust architecture keeps all devices unit-network perimeter are not trusted by default. Every device, user, and application on the network must confirm its identity to the system, and it must be authorized as a user or operation before being given access of use.
The inadequately configured transmitter, even if well-secured, will be no different from a liability. Changing factory-set passwords, disabling ports not in use, and regularly updating firmware to address vulnerabilities creates a good security posture for any business. Manufacturers typically release security patches due to a notified threat. Neglecting to install an update can leave systems exposed to compromise.
Wireless transmitters in the B2B context are expected to support OTA updates for secure firmware updates over the air without the need for physical access.
One way to establish foolproof data security is through periodic security audits and penetration testing. Through this weak configuration points can be found out. Such measures are vital to establish compliance with cybersecurity standards pertinent to various industries.
When it comes to regulations that guide the majority of industries, there are stipulations for the secure handling of data. One example of such stipulation is the HIPAA which states that healthcare need to safeguard sensitive information. In the EU, the GDPR regulation governs the sharing of data. According to this the manufacturers are required to secure the personal or sensitive data during transmission. Wireless transmitters used in these specific scenarios would certainly need to comply with higher standards for security. This usually involves maintaining audit logs and encryption standards.
Customers should select wireless transmitter suppliers certified in recognized security certifications, such as ISO/IEC 27001 for information security management and NIST standards for the requirement in data encryption and protection. Most of all, given this criteria certification, one gets a secure assurance that these devices will be used globally, keeping in view the various international security standards.
With the prominence of IoT and real-time analytics, edge computing poses a powerful ally in ensuring precise securing of wireless data transfer. In simple terms, when most data is processed at the edge rather than to the cloud, the organization will conserve true exposure by using less amount of data transmission sent through wireless channels.
Wireless transmitters that incorporate edge computing capabilities can analyze, filter, and encrypt data before it is sent to the cloud or central servers. Such a feature not only protects the data but also boos the speed and efficiency of the transmitter making it more suitable for commercial B2B applications where customer data is quite sensitive.
In the coming years, businesses will start embracing increasingly sophisticated wireless technologies, moving on from 5G to ultra-wideband (UWB) communications, and this will start a shift in the security landscape. While yielding all the advantages of more speed and lower latency, such advanced applications bring with them new vulnerabilities. One such vulnerability manifests itself as the massive device density enabled by 5G networks, thereby increasing the number of endpoints open to targeting by cyber criminals.
Artificial intelligence or machine learning is becoming a substantial involvement in offense and defense in cybersecurity. This has become so in that the defense part is considered in the form of AI-driven threat detection systems, tracking and analyzing data from anomalous sites in real time. On the contrary, the offensive side will use AI-assisted tools to design more sophisticated and targeted attacks. Staying ahead will mean continuous investment in research, and adaptation of policies.
The security of transferring data is important for B2B applications, where speed, accuracy, and reliability are expected. Even if wireless connections may be considered more vulnerable than wired versions, security can be created by implementing strong encryption, making correct configurations, segmenting the networks, and maintaining them. All in all, securing wireless transmitters goes beyond just data protection. This practice is vital for establishing and maintaining customer trust, and also for gaining a competitive edge in the digital world.
