In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
Cold start (or cold boot) may also refer to a booting process of a single computer (or virtual machine). [2] In this case services and other startup applications are executed after reboot. The system is typically made available to the user even though startup operations are still performed and slow down other operations.
Reboot to restore software is a system of restore technology that enables restoring the user-defined system configuration of a computing device after every restart. [1] The technology maintains systems in their optimal working conditions and is used in multi-user computing environments.
The corrective actions typically include placing the computer and associated hardware in a safe state and invoking a computer reboot. Microcontrollers often include an integrated, on-chip watchdog. In other computers the watchdog may reside in a nearby chip that connects directly to the CPU , or it may be located on an external expansion card ...
Windows Me does not allow a computer to boot into a DOS Kernel by shutting down Windows Me; thus TSRs became useless on Windows Me. The Windows NT series (including Windows 2000 , Windows XP , and later) replaced DOS completely and run in protected mode or long mode (later 64-bit versions only) all the time, disabling the ability to switch to ...
The key is kept in the memory if the WannaCry process has not been killed and the computer has not been rebooted after being infected. [75] This behaviour was used by a French researcher to develop a tool known as WannaKey, which automates this process on Windows XP systems.
Apple Computer's first computer, the Apple 1 introduced in 1976, featured PROM chips that eliminated the need for a front panel for the boot process (as was the case with the Altair 8800) in a commercial computer. According to Apple's ad announcing it "No More Switches, No More Lights ... the firmware in PROMS enables you to enter, display and ...
At boot time, a workstation that has been set to boot from PXE will issue a BOOTP request via the network. Once the request is received, the DHCP Server will supply an IP address to the machine, and the DNS server will point the client computer to the RIS server, which in turn will issue a disc boot image (often called the "OS Chooser").
