Abstract: A method of acquiring an operational certificate for an application (140) running on an authorized and/or authenticated host node (130) in a network (100), the method comprising: transmitting, by the application, a request comprising a Certificate Signing Request to a proxy engine (145) running on the authorized and/or authenticated host node; receiving, by the proxy engine, the request, and submitting the Certificate Signing Request to a Certificate Authority (155); signing, by the Certificate Authority, the operational certificate and transmitting a response comprising the signed operational certificate to the proxy engine; and forwarding, by the proxy engine, the signed operational certificate to the application.

Abstract: Certain aspects of the disclosure are directed toward validation and installation of a file system. A method for mitigating security breach for a circuit platform subject to compromise by unauthorized changes to a file system includes abstracting the file system into an encrypted file with cryptographically signed components. The file system may have instruction code or other data for an operating system and may be stored by or on behalf of the circuit platform. During boot time of the operating system, an unencrypted version of the operating system and the encrypted file may be accessed and used by validating a signature associated with the file system. In response to validating the signature, the file system is installed into a transient, non-persistent storage circuit. As such, the operating system executes instruction code via a central processing unit (CPU) circuit under authorization based on the validated signature.

Abstract: A method for restricting write cycles to a storage device includes tracking a first count of a first set of writes to memory executed by a first subsystem of a computing device and, further, determining that the first count meets a write threshold of the first subsystem. The method includes determining that blocking criteria are met by the first subsystem based on the first count exceeding the write threshold of the first subsystem and, further, determining that blocking criteria are not met by a second subsystem of the computing device. The method includes blocking the first set of writes from being synchronized to the storage device, based on the blocking criteria being met by the first subsystem, and synchronizing memory contents of the second subsystem to the storage device, based on the blocking criteria not being met by the second subsystem.
