Ambarella, Inc., an artificial intelligence (AI) vision silicon company, announced that Ambarella and Amazon Web Services, Inc. (AWS) customers can now use Amazon SageMaker Neo to train machine learning (ML) models once and run them on any device equipped with an Ambarella CVflow-powered AI vision system on chip (SoC). Until now, developers had to manually optimize ML models for devices based on Ambarella AI vision SoCs.

This step could add considerable delays and errors to the application development process. Ambarella and AWS collaborated to simplify the process by integrating the Ambarella toolchain with the Amazon SageMaker Neo cloud service. Now, developers can simply bring their trained models to Amazon SageMaker Neo and automatically optimize the model for Ambarella CVflow-powered SoCs.

Neural network accelerator

Customers can download the compiled model and deploy it to their fleet of Ambarella-equipped devices

Customers can build an ML model using MXNet, TensorFlow, PyTorch, or XGBoost and train the model using Amazon SageMaker in the cloud or on their local machine. Then, they can upload the model to their AWS account and use Amazon SageMaker Neo to optimize the model for Ambarella SoCs. They can choose CV25, CV22, or CV2 as the compilation target.

Amazon SageMaker Neo compiles the trained model into an executable that is optimized for Ambarella’s CVflow neural network accelerator. The compiler applies a series of optimization that can make the model run up to 2x faster on the Ambarella SoC. Customers can download the compiled model and deploy it to their fleet of Ambarella-equipped devices.

Enterprise video security

The optimized model runs in the Amazon SageMaker Neo runtime purpose-built for Ambarella SoCs and available for the Ambarella SDK.The Amazon SageMaker Neo runtime occupies less than 10x the disk and memory footprint of TensorFlow, MXNet, or PyTorch, making it much more efficient to deploy ML models on connected cameras.

“Ambarella is in mass production today with CVflow AI vision processors for the home monitoring, enterprise video security, and automotive markets,” said Chris Day, vice president of marketing and business development for Ambarella. "The ability to select an Ambarella SoC and compile a trained ML model with a single click is a powerful tool that makes it possible for our customers to rapidly bring the next generation of AI-enabled products to market.”

Advanced security features

AWS has the deepest set of ML and AI services focused on solving some of the toughest challenges facing developers"

Manufactured using an advanced 10-nanometer process, Ambarella’s CVflow SoC family enables the design of compact, high-performance vision systems with ultra-low power operation. For example, the Ambarella CV22 CVflow SoC delivers computer vision processing at full 4K or 8-megapixel resolution at 30 frames per second (fps), while its image signal processor (ISP) provides outstanding imaging in low- light conditions and high-contrast scenes, further enhancing the computer vision capabilities of the chip.

The CV22 also includes a suite of advanced security features to protect against hacking including secure boot, TrustZone, I/O virtualization, and support for online upgrades over the air (OTA).

Machine learning models

“AWS has the broadest and deepest set of ML and AI services focused on solving some of the toughest challenges facing developers. Amazon SageMaker is a fully managed service that provides every developer and data scientist with the ability to build, train, and deploy machine learning models quickly,” said Bratin Saha, Vice President, Machine Learning & Engines, Amazon Web Services, Inc.

“We’re excited that VIVOTEK is using SageMaker Neo to simplify the deployment of ML models at the edge on Ambarella CVflow-powered IP cameras.”

Water Plant Attack Emphasizes Cyber’s Impact On Physical Security
Water Plant Attack Emphasizes Cyber’s Impact On Physical Security

At an Oldsmar, Fla., water treatment facility on Feb. 5, an operator watched a computer screen as someone remotely accessed the system monitoring the water supply and increased the amount of sodium hydroxide from 100 parts per million to 11,100 parts per million. The chemical, also known as lye, is used in small concentrations to control acidity in the water. In larger concentrations, the compound is poisonous – the same corrosive chemical used to eat away at clogged drains. The impact of cybersecurity attacks The incident is the latest example of how cybersecurity attacks can translate into real-world, physical security consequences – even deadly ones.Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. The computer system was set up to allow remote access only to authorized users. The source of the unauthorized access is unknown. However, the attacker was only in the system for 3 to 5 minutes, and an operator corrected the concentration back to 100 parts per million soon after. It would have taken a day or more for contaminated water to enter the system. In the end, the city’s water supply was not affected. There were other safeguards in place that would have prevented contaminated water from entering the city’s water supply, which serves around 15,000 residents. The remote access used for the attack was disabled pending an investigation by the FBI, Secret Service and Pinellas County Sheriff’s Office. On Feb. 2, a compilation of breached usernames and passwords, known as COMB for “Compilation of Many Breaches,” was leaked online. COMB contains 3.2 billion unique email/password pairs. It was later discovered that the breach included the credentials for the Oldsmar water plant. Water plant attacks feared for years Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. Florida’s Sen. Marco Rubio tweeted that the attempt to poison the water supply should be treated as a “matter of national security.” “The incident at the Oldsmar water treatment plant is a reminder that our nation’s critical infrastructure is continually at risk; not only from nation-state attackers, but also from malicious actors with unknown motives and goals,” comments Mieng Lim, VP of Product Management at Digital Defense Inc., a provider of vulnerability management and threat assessment solutions.The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online “Our dependency on critical infrastructure – power grids, utilities, water supplies, communications, financial services, emergency services, etc. – on a daily basis emphasizes the need to ensure the systems are defended against any adversary,” Mieng Lim adds. “Proactive security measures are crucial to safeguard critical infrastructure systems when perimeter defenses have been compromised or circumvented. We have to get back to the basics – re-evaluate and rebuild security protections from the ground up.” "This event reinforces the increasing need to authenticate not only users, but the devices and machine identities that are authorized to connect to an organization's network,” adds Chris Hickman, Chief Security Officer at digital identity security vendor Keyfactor. “If your only line of protection is user authentication, it will be compromised. It's not necessarily about who connects to the system, but what that user can access once they're inside. "If the network could have authenticated the validity of the device connecting to the network, the connection would have failed because hackers rarely have possession of authorized devices. This and other cases of hijacked user credentials can be limited or mitigated if devices are issued strong, crypto-derived, unique credentials like a digital certificate. In this case, it looks like the network had trust in the user credential but not in the validity of the device itself. Unfortunately, this kind of scenario is what can happen when zero trust is your end state, not your beginning point." “The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online for the first time as part of digital transformation projects,” says Gareth Williams, Vice President - Secure Communications & Information Systems, Thales UK. “While the move towards greater automation and connected switches and control systems brings unprecedented opportunities, it is not without risk, as anything that is brought online immediately becomes a target to be hacked.” Operational technology to mitigate attacks Williams advises organizations to approach Operational Technology as its own entity and put in place procedures that mitigate against the impact of an attack that could ultimately cost lives. This means understanding what is connected, who has access to it and what else might be at risk should that system be compromised, he says. “Once that is established, they can secure access through protocols like access management and fail-safe systems.”  “The cyberattack against the water supply in Oldsmar should come as a wakeup call,” says Saryu Nayyar, CEO, Gurucul.  “Cybersecurity professionals have been talking about infrastructure vulnerabilities for years, detailing the potential for attacks like this, and this is a near perfect example of what we have been warning about,” she says.  Although this attack was not successful, there is little doubt a skilled attacker could execute a similar infrastructure attack with more destructive results, says Nayyar. Organizations tasked with operating and protecting critical public infrastructure must assume the worst and take more serious measures to protect their environments, she advises. Fortunately, there were backup systems in place in Oldsmar. What could have been a tragedy instead became a cautionary tale. Both physical security and cybersecurity professionals should pay attention.
