The object of the container network model (CNM) that contains the configuration files of a container’s network stack, such as routing table, container’s interfaces, and DNSsettings, is the Sandbox. A Sandbox is a logical entity that encapsulates the network configuration and state of a container. A Sandbox can contain one or more endpoints from different networks, and provides isolation and security for the container’s network stack. A Sandbox can be implemented using various technologies, such as Linux network namespaces, FreeBSD jails, or Windows compartments.A Sandbox allows the container to have its own view and control of the network resources, such as interfaces, addresses, routes, and DNS settings123.References:

System-based risk is a type of mobile device security risk that arises from the vulnerabilities or flaws in the operating system or firmware of the device. System-based risk can expose the device to malware, spyware, ransomware, or other malicious attacks that can compromise the data, functionality, or privacy of the device. System-based risk can be mitigated by applying regular security updates and patches from the manufacturer or vendor, as well as using antivirus or anti-malware software. In the above scenario, Stella’s device faced a system-based risk, as it ran with an obsolete OS version that had vulnerabilities that allowed the files to be replaced. She ignored the messages from the manufacturer for updates, which could have prevented the risk.References:
