Security - Tips On How To Protect Your Devices From Meltdown And Spectre Processor Security Flaws

Security researchers this week dropped a bombshell on pretty much everyone who owns a computer, saying there are inherent flaws in modern processors that could allow an attacker to access sensitive information, including passwords and other contents stored in what’s supposed to be protected memory. At first it was reported that only Intel processors were affected, but later analysis has revealed that AMD and ARM chips are flawed as well. It’s a stinky situation, right?

Well, yes, it certainly is. But it doesn’t have to be dire. To quickly rehash, the flaws have been dubbed Meltdown and Spectre. It was the former that was talked about most at the beginning, and for the time being, it seems limited to Intel chips, albeit every Intel processor made since 1995 (specifically, those that implement out-of-order execution). Spectre is a serious security flaw as well, and it affects all modern processors, including ones from Intel, AMD, and ARM.

There are patches being doled out to mitigate the risk, the impact of which is still being assessed. Early reports said they could cause anywhere from a 5 percent to 30 percent performance hit, though Intel refutes this, saying the fallout is highly workload dependent that most users will see little to no impact. That claim will be fact checked over time.
