AppLocker whitelists applications by creating rules that specify which files are allowed to run. One of the primary methods for specifying these rules is through the use of Path Rules. Path Rules allow administrators to specify an allowed file or folder path, and any application within that path is permitted to run. This method is particularly useful for allowing applications from a known directory while blocking others that are not explicitly approved.

References: The official Microsoft documentation explains that AppLocker functions as an allowlist by default, where only files covered by one or more allow rules are permitted to run. Path Rules are a fundamental part of this allowlisting approach1. Additionally, other resources like security guidelines and best practices for Windows reinforce the use of Path Rules as a method for application whitelisting within AppLocker2

Chip-level security for IoT devices is achieved by implementing security measures directly into the hardware, such as secure boot, secure firmware updates, and device authentication. This involves storing cryptographic keys in a tamper-resistant environment within the chip, ensuring that sensitive information remains secure even in the event of physical attacks on the device. Closing insecure network services is part of a broader security strategy that includes chip-level measures to protect against cyberattacks. It’s important to note that while changing passwords and encrypting interfaces are also security measures, they do not pertain specifically to chip-level security.

References: The information provided is based on industry best practices and insights from sources such as EE Times1 and Semiconductor Digest2, which discuss the importance of establishing a root of trust and securing IoT devices from chip to cloud. These sources emphasize the need for a focus on endpoint devices and the implementation of security mechanisms and techniques depending on their specific function and security requirements. Additionally, they highlight the role of public key infrastructure (PKI) in providing strong identities for IoT devices, which is a critical element of chip-level security.

 In the context of containerization, setting resource limits is crucial for ensuring that applications do not consume more than their fair share of system resources. Michelle can limit a container to use only 2 CPUs by using the --cpus flag when running a container. This flag allows the user to specify the amount of CPU the container is limited to use. For example, --cpus="2" would restrict the container to using no more than two CPU cores.

References: This information is based on standard practices for managing Docker containers and their resources. The --cpus flag is a well-documented feature in Docker’s command-line interface for controlling CPU usage1.
