US 2022/0012342 A1 · PROTOCOL SECURITY SYSTEM

Abstract

A protocol security system includes a protocol producer driver stored in a first memory range on a primary memory system, a protocol consumer driver stored on the primary memory system, and a firmware interface engine provided via the primary memory system. The firmware interface engine receives a protocol pointer from the protocol consumer driver, and identifies that the protocol pointer was provided by the protocol producer driver. If the firmware interface engine determines that the protocol pointer is not stored in the first memory range on the primary memory system, it generates a protocol security violation. If the firmware interface engine determines that the protocol pointer is stored in the first memory range on the primary memory system and points to an architectural protocol, it determines whether the protocol producer driver originated from a secondary memory system and, if not, generates a protocol security violation.

Dependent claims

A protocol security system, comprising:

a first protocol producer driver that is stored in a first memory range on a primary memory system;
at least one protocol consumer driver that is stored on the primary memory system;
and
a firmware interface engine that is provided via the primary memory system and that is configured to:
receive, from the at least one protocol consumer driver, a first protocol pointer;
identify that the first protocol pointer was provided by the first protocol producer driver;
determine, in response to identifying that the first protocol pointer was provided by the first protocol producer driver, that the first protocol pointer is not stored in the first memory range on the primary memory system;
and
generate, in response to determining that the first protocol pointer is not stored in the first memory range on the primary memory system, a protocol security violation.

6 more elements

An Information Handling System (IHS), comprising:

a processing system;
and
a primary memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a firmware interface engine that is configured to:
receive, from at least one protocol consumer driver that is stored on the primary memory system, a first protocol pointer;
identify that the first protocol pointer was provided by the first protocol producer driver;
determine, in response to identifying that the first protocol pointer was provided by the first protocol producer driver, that the first protocol pointer is not stored in a first memory range on the primary memory system that is associated with the first protocol producer driver;
and
generate, in response to determining that the first protocol pointer is not stored in the first memory range on the primary memory system that is associated with the first protocol producer driver, a protocol security violation.

5 more elements

A method for securely performing protocols, comprising:

receiving, by a firmware interface engine from at least one protocol consumer driver that is stored on a primary memory system, a first protocol pointer;
identifying, by the firmware interface engine, that the first protocol pointer was provided by the first protocol producer driver;
determining, by the firmware interface engine in response to identifying that the first protocol pointer was provided by the first protocol producer driver, that the first protocol pointer is not stored in a first memory range on the primary memory system that is associated with the first protocol producer driver;
and
generating, by the firmware interface engine in response to determining that the first protocol pointer is not stored in the first memory range on the primary memory system that is associated with the first protocol producer driver, a protocol security violation.
