Detecting alteration of boot code

An information processing apparatus, comprising a setting unit that executes a security setting on the information processing apparatus based on an installation environment of the information processing apparatus, wherein the setting unit executes the security setting again at a specific timing.

Information processing apparatus, control method of information processing apparatus, and storage medium

An information processing apparatus comprising a verification unit configured to verify, among a plurality of divided parts of software to be started up, a part of software to be started up next and setting data relating to startup of the part of software to be started next.

Information processing apparatus, information processing method, and storage medium

An information processing system includes a management server and a multi-function peripheral (MFP). The management server specifies an environment of a network to which the MFP is connected, selects a security policy associated with the specified environment of the network, and delivers the security policy to the MFP. The MFP receives the security policy associated with the environment of the connected network from the management server, and applies the security policy.

An information processing apparatus includes a rewrite request receiving unit configured to receive a rewrite request for rewriting an execution module, an update module determination unit configured to determine whether an update module that issues the rewrite request is an authorized module, a first falsification detection unit configured to detect falsification of a whitelist, an unauthorized-rewriting prevention unit configured to prevent unauthorized rewriting while maintaining a function of the information processing apparatus by rejecting the rewrite request without stopping the function of the information processing apparatus, in a case where the execution module for which the rewrite request is issued is registered in a whitelist for which the first falsification detection unit determines that no falsification is made and where the rewrite request is issued by an update module for which the update module determination unit determines to be an unauthorized update module.

Information processing apparatus, information processing method, and storage medium for detecting falsification of a module

An information processing apparatus stores first software and second software, the first software is stored in a first storage medium accessible by a central processing unit and an embedded controller, and the second software is used to restore the first software and stored in a second storage medium accessible by the embedded controller. The information processing apparatus includes an update unit configured to update the second software using the first software depending on a result of a comparison between version information about the first software and version information about the second software, a falsification detection unit configured to detect whether the first software is falsified; and a restoration unit configured to restore the first software using the second software in a case where the falsification detection unit detects that the first software is falsified.

An apparatus comprising: a unit configured to verify whether a first region that specifies a verification range of a first boot code and a second region that specifies a verification range of a second boot code have been altered; a unit configured to, when the first region has not been altered, verify whether the first boot code has been altered; a unit configured to, when the first boot code has been altered and the second region has not been altered, verify whether the second boot code has been altered; and a unit configured to, when the second boot code has not been altered, restore the first boot code using the second boot code, wherein the first and second regions are regions that are not rewritten after a start of the apparatus.

An information processing apparatus includes a verification unit configured to verify, using a method starting with hardware verification at a time of startup of a system, partial software which is divided into a plurality of parts and gradually started up, a second verification unit configured to verify another partial software based on the verified partial software, and a third verification unit configured to verify software to be executed at an arbitrary timing prior to execution of the software. In a case where the third verification unit is in operation at a time of update of the partial software, the operation of the third verification unit is stopped, and restart is performed after completion of the update, so that a sequence of verification processes starting with the hardware verification up to a result of verification at a time of execution is applied.
