UltraSoC Releases Next Generation Hardware-Based Network Security Products

UltraSoC today announced a new generation of hardware-based network security products that can be used to detect, block and record a wide range of cyber attacks, covering a wide range of applications, from vehicles and factory robots to consumer devices.

The embedded monitor detects, blocks, and logs attacks and prevents propagation.

UltraSoC today announced a new generation of hardware-based network security products that can be used to detect, block and record a wide range of cyber attacks, covering a wide range of applications, from vehicles and factory robots to consumer devices.

These new products embed advanced real-time network security protection into system-on-chip (SoC) to support and control every modern product. The first product in the series, the UltraSoC Bus Sentinel, enables SoC designers to control access to sensitive areas of their devices, instantly detect and block suspicious transactions, and establish a long-term collection of system operations to protect against current and future networks. Threat.

UltraSoC’s security solutions enable designers to integrate a separate internal monitoring system into their chips. This will continue to check that the device is operating as expected and to detect anomalous behavior that may indicate a security breach. Because it is embedded in the hardware, it can respond in real time (in microseconds, not the milliseconds required for traditional threat mitigation), it can be hard to be destroyed or circumvented, even for chip designers. A “zero-day” type of attack is blocked. In addition to detecting and blocking cyber threats, it can also be used to trigger actions that block propagation and provide an event “black box” record that can be used as evidence.

UltraSoC Chairman Alberto Sangiovanni-Vincentelli commented: “In this era of autonomous vehicles, ubiquitous connectivity and increasing reliance on technology, cybersecurity is one of the biggest challenges for technicians. We think we have one now. A truly unique solution to these problems: this is why more and more customers are turning to UltraSoC to ensure that their product functions operate safely, reliably and completely in their design mode.”

The new Bus SenTInel module monitors and controls the internal bus of the SoC and observes how the interconnected subunit modules interact in the chip. It can also be configured at run time to detect specific transaction types, such as a process attempting to access a memory controller’s control registers at any time other than a system restart, or an insufficiently privileged process attempting to access a protected memory region. The inspection process itself is performed through a series of configurable filters that can be cascaded to achieve complex conditions and detect extremely subtle differences in system behavior.

In addition to its detection capabilities, the Bus SenTInel can be configured to respond to threats in real time in a variety of ways: it allows transactions to be made without modification; it uses transaction gating techniques to block transactions in the monitor It goes on; it can modify the transaction in some way, for example by a flag, and it can generate a response on the bus. It can also issue a trigger event through a dedicated UltraSoC communication network fabric, allowing other system unit modules or external threat mitigation systems to generate instant responses.

David Rogers, CEO of Cyber ​​Horse’s Cyber ​​Horse professional and MBE medal winner, said: “As the threat camp continues to evolve and the consequences of attacks become more and more interesting, implementing security features in hardware has many advantages. Security is rooted in the heart of the SoC, and UltraSoC’s technology helps designers monitor, detect and resolve security issues at the most basic level they can achieve today.”

Bus SenTInel’s filters, counters, and timer systems allow it to be configured to detect common known security threats. These powerful features provide system designers with a variety of methods to handle any given threat vector. Suspicious transactions can be detected and tagged, and subsequent sequence events are monitored without the attacker’s knowledge, thereby analyzing the threats. Transactions can be blocked by responding to the initiator and collecting more information. Or the Bus SenTInel can trigger a response anywhere else in the system on the chip and communicate through a dedicated UltraSoC communication network structure.

Equally important, the Bus Sentinel is equipped with storage units that can record data for use by the filter in future transaction identification. It can also be used with the entire UltraSoC infrastructure to collect large amounts of statistical data. This can be used by the on-chip analytics engine or passed to an external cloud-based analytics system to analyze the system based on many deployed instances of the device and generate a “signature” of normal behavior. This in turn enables the threat mitigation system to adapt to the rapidly evolving threat camp.

The UltraSoC Bus Sentinel will be fully available in the first quarter of 2020. Its modular design enables it to support any bus protocol and directly supports popular on-chip buses including Arm APB, AHB, AXI-4 and ACE.
