Posted on by

Intel does not plan to release microcode updates for older generations of processors that are affected by the Spectre vulnerability, either because patching is not practical and for other reasons. The company released a microcode revision guidance doc… Continue reading Intel Won’t Patch Spectre on All CPUs→

DARPA is looking to avoid another version of Meltdown or Spectre

Posted on by

The Defense Advanced Research Projects Agency has contracted Tortuga Logic to develop hardware security tools that use commercial testing platforms to catch vulnerabilities in computer chips before they are deployed, the firm announced. The goal of the contract, awarded by the Pentagon’s R&D arm, is to prevent a repeat of Meltdown and Spectre, the security vulnerabilities revealed in January that affected virtually all modern computer chips. The contract is part of a DARPA hardware and firmware program that strives to make chips more secure at the “microarchitecture level.” DARPA says the program, which is tackling seven classes of hardware vulnerabilities, supports security methods that limit “hardware to states that are assured to be secure while maintaining the performance and power required for system operation.” Tortuga Logic says it can verify hardware security throughout the design process, arguing in a recent white paper that such verification is much more common in […]
