With technology rapidly developing around us, the medical field has seen a huge leap in reaching consumers and providing them with better service. The Internet of Things has played a major role in making life much easier, but at the same time, there are hidden dangers behind IoT security holes. A less secure healthcare system can easily put people’s lives at risk, and therefore, security should never be behind. Many medical devices such as pacemakers, glucose monitors, depression and mood monitors are part of the Medical Internet of Things, which ensures immediate medical service even with little or no early signs or warnings of a patient’s condition. The data processed by these devices is extremely important and confidential. Any devices that are part of the Internet of Things are vulnerable to all kinds of cyber attacks. Hackers can tamper with medical devices and/or data, which could lead to unpredictable negative consequences for patients, hospital management and the product companies involved. Another threat is counterfeiting of original medical device parts. Medical devices with fake internal parts may not always guarantee proper performance and thus become a deadly challenge during critical times. Imitation can cause huge losses in life and money, as well as loss of brand reputation. This leads to times when the reliability of the product manufacturer is questioned and end consumers knowingly or unintentionally become a part of the fraud. What effective steps can be taken against healthcare IoT security attacks? A comprehensive, multi-layered security solution is something that can ensure the smooth functioning of healthcare IoT devices. The multi-layered security solution focuses not only on the software aspects but on the hardware components that ensure a secure environment. Here comes the importance of hardware root and chain trust. The origin of trust is now a popular phrase among security experts. The root of trust, which is the initial point of the chain of trust, runs from hardware to software, which ultimately secures other connected devices and makes the entire system relentless. Thus, the device must be able to run only the authenticated code and provide secure access to persistent storage. From the SoC level, with a validated bootable token, security should extend over external network connections to and from the device, ensuring that data is always sent and received only between the intended parties. How does the security package deliver better security against threats in the healthcare IoT? Security Suite is a comprehensive, multi-layered, comprehensive security solution with minimal integration effort for a new platform. Security Suite provides security services at every level, from SoC to the cloud. Thus, Security Suite acts as an integrated package of widely accepted security strategies to ensure a safe and reliable environment for end customers. The Security Suite includes the following components: Secure Boot: Events have been reported where people with diabetes had a tendency to build their own system by reusing various other hardware, possibly to reduce cost or to customize the work of the system. This came to light when a critically ill patient ended up with his custom medical device. These types of situations can be stopped completely using the secure boot feature. The Security Suite promises that the target platform always comes with a reliable, bootable image. Secure Boot is an effective weapon against attacks where a third party can take control of the entire system using a bootable image or newly created malware. Secure boot ensures SoC-level security using the CAAM module and random number generator. This feature makes the SoC simply reject rogue and unexpected code. Secure partitioning: Privacy is an important factor and one of the biggest concerns in the medical field, with the attacker having a huge advantage in exploiting the data. Private data such as patient records and medical images such as X-rays and CT scans should not be exposed or compromised by any kind of manipulation. Technically, keys and certificates for system encryptions should also be highly protected. These components must be well maintained and kept from any kind of attack or sharing risk. So the need for secure partitioning is beyond doubt. The key set used to encrypt the secure partition is from the CAAM module and is highly unique and unexpected. These attributes add to the security level and the secure storage partition will be in a completely closed state once it is removed from the system, leaving the attacker helpless. The secure partition APIs, which are part of the security suite, provide flexibility and ease for customers to create and maintain a highly secure partition for their target platforms. Wireless Security: When we talk about wireless technology today in the medical field, there is a huge demand for wireless pacemakers, which periodically send patient data to an external device via Wi-Fi. This helps doctors reduce monitoring tasks. But this kind of external connection to the system can be easily exploited by attackers. Wireless communication in particular has always been a vector for attack and another type of eavesdropping for hackers. Security Suite has adopted methods to ensure secure wireless communication through recommended IEEE 802.11 security standards along with automatic active intrusion detection system and firewall services. The secure scan feature blocks any kind of attempt to establish a connection to unsecured networks and the classic auto connect feature is completely disabled to avoid future connections with scammers. Together with devices that have tamper detection capability, a secured wireless connection with communication parameters unique and vendor-specific can be used to detect counterfeit parts. Wireless security features can be easily integrated with any platforms through APIs. Secure TLS Connection: Cloud-based medical IoT should always be at the forefront in terms of efficiency in storing and accessing data for analysis. Medical data is often time-critical and confidential, and this efficiency requires higher security when sending data over the network to the cloud. The transmitted data must be encrypted to avoid eavesdropping and hijacking by attackers. Security Suite is integrated with TLS communications services secured by wolfSSL cipher libraries. This enables a secure and secure cloud connection to the target platform. The APIs allow the end customer to take advantage of TLS facilities and integrate them into their applications with great ease. Error logging mechanism: The error logging mechanism can be considered the “black box” of the system when any unfavorable event occurs. Error logs help track if something goes wrong and check for warnings and alerts for malicious activity against the system. This will help to take timely measures and avoid a complete disaster. Error logging is important for the same reason the Security Suite includes error logging as one of its core components. iWave provides a complete Security Suite solution for end customers to rely on to build their own secure product. The Security Suite solution allows customers to focus on other aspects to improve time to market without worrying about how security is ensured at every stage of the product’s operation from boot to cloud. iWave also offers customized security solutions based on requirements: Enable security features on different ARM processors Support for portability for new versions of software and platforms Support on multiple cloud platforms such as IBM Watson IoT Platform, Amazon AWS and Microsoft Azure More detailed information about Security can Suite can be found here or a quick video can be viewed here. .
