will release server
this year with hardware features designed to block attacks that use serious new Spectre vulnerabilities, Chief Executive
The Spectre "side channel" attacks lets one software process snoop on another, gathering sensitive data like passwords or
keys. The industry has been scrambling to issue software patches to
and web browsers to thwart such attacks, but Intel now has detailed plans to block them with the chips themselves.
The fix will come later this year in the company's latest generation of Xeon server chips, called Cascade Lake and built for servers found by the thousands in data centers run by companies like
. The Spectre-snooping possibility is a particular problem for them since a server in cloud-computing services often handles jobs from different customers simultaneously.
Intel's fix uses a partitioning technology that effectively puts walls around different applications to block snooping, Intel said.
In the meantime, Intel has made progress on setting things right with existing chips.
"We have now released microcode updates for 100 percent of Intel products launched in the past five years that require protection against the side-channel method vulnerabilities discovered by Google," Krzanich said in a statement.
These are important steps in Intel's effort to get itself out of the Spectre hole. The company's stock price was punished when security researchers at Google and other firms revealed Spectre and a conceptually related attack called Meltdown. Adding insult to injury, some Intel software updates caused unexpected reboots.
But it's still just a step. Intel also plans to bring the update to a new version of its current Kaby Lake Xeon processors this year, but it's not yet clear when PC processors will get the fix. The fix will address the two variants of Spectre, but Intel is relying on software updates to block Meltdown attacks.
A big problem with patching the Spectre and Meltdown vulnerabilities is that the fixes curtailed acceleration features built into the software. Nobody wants a slower computer.
Addressing the problem in hardware has the potential to fix things without as much of a performance penalty. However, it wasn't immediately clear what effect the hardware fix will have on performance.
Intel wasn't alone in suffering from Spectre. It affects other chipmakers, too, including those building chips for PCs,
and other devices.
Krzanich on Thursday also offered a reminder that security fixes go only so far if users don't do their part.
"I encourage everyone to make sure they are always keeping their systems up-to-date," he said. "It's one of the easiest ways to stay protected."
