Is the management software that performs security relevant management operations and used when exercising security management procedures and controls. Chapter 6 is dedicated to covering the network protocols themselves. The network stack subsection covers software elements needed to secure the network stack, like firewalls and intrusion detection systems (IDS). It includes communication protocols and network interfaces. It straddles both the application/data plane and the management plane, because it is used extensively by both. Additionally, the network stack is the entry point for the majority of attacks on IoT systems. The network stack deserves its own separate treatment because it actually enables a system to communicate with other devices, turning that system into an Internet of Things device. However, for our purposes, including it in the operating system obscures it and diminishes its importance to IoT systems. Is most often included in the system software or part of the operating system. The management plane software is made up of security management, device management, and the system update service. Moving up from the platform software to the application software, we look at the management plane. These are shown in the diagram to aid in understanding the connection between the application part of the stack and the platform software. We devote a bit of time to discuss the differences and benefits of each.įigure 4-2 also shows two components that are not covered individually, but will be interspersed among the other platform software components: the filesystem and the network drivers. Both containers and virtualization with hypervisors provide containment. This level of additional containment improves security by reducing privileges and controlling unintended interactions between applications. The software containment element is optional, but if provided on the system includes technologies like containers and Trusted Execution Environments (TEE). This chapter does not cover any of these elements, but refers back to the content in Chapter 3 where appropriate.ĭirectly above the hardware is the operating system/hypervisor element which is the system software in direct control of the hardware and may be a commercial or open source operating system, or it may be an hypervisor that creates one or more virtual hardware devices for the rest of the software to operate within. All hardware is implied by this element, including the processor, memory subsystems, flash and other storage, security coprocessors, wired and wireless communication hardware, or anything else physically connected to the processing unit and its motherboard. Check the manufacturer’s instructions to see if an LED on the motherboard will signal the end of the update.Beginning at the bottom is the hardware covered in Chapter 3. #INTEL BIOS UPDATE CAPSULE HEADER INVALID PC#It’s important not to power down or restart your PC until the process is complete. Regardless of the installation method, a BIOS update can take around five minutes. Some motherboards even have specific ports and LEDs dedicated to this update process. #INTEL BIOS UPDATE CAPSULE HEADER INVALID DOWNLOAD#Similar utilities may also be available for download and installation onto a USB drive. #INTEL BIOS UPDATE CAPSULE HEADER INVALID MANUAL#The tools for installing the BIOS update from here will vary by manufacturer, but step-by-step instructions can be found either in the manual or the manufacturer’s website.ĭepending on the manufacturer, a simple update method may also be provided, such as a USB stick included with your motherboard that updates the BIOS from within Windows.
