Intel’s plan to save cloud computing is to make walls, virtually. Earlier this year we released an alert to our customers regarding the Intel vulnerabilities Spectre and Meltdown. Intel has now released plans to install “Virtual Fences” in all future CPUs, starting with Cascade Lake (codenamed). “We have redesigned parts of the processor to introduce new levels of protection through partitioning that will protect against both Variants 2 and 3,” Brian Krzanich, CEO of Intel, said in a blog post. “Think of this partitioning as additional “protective walls” between applications and user privilege levels to create an obstacle for bad actors.”
The IT industry continues to wait to hear more in-depth details of these updates including how they will effect performance.
Intel did patch its current processor platforms Skylake, Kaby Lake, and Cannon Lake in February. However, these patches were known to have performance impacts while the proposed “virtual walls” are stated to be much more efficient in terms of performance impact.
