Meltdown and Spectre - What to do about it

[techlists at phpcoderusa.com]

Hi, 

I'm looking for more info or ideas on how one might protect them self
given Meltdown and Spectre. 

Now that it has come to light that computer memory is not completely
segregated or kept private by the CPU hardware... a failure in design
allowing a hacker access to even the CPU Kernel memory.  This is
catastrophic.   

I'm reading the initial solution is for the O/S manufactures to patch
their Kernel to secure the memory at its boundaries.  In and of itself
this seems to be a weak approach, however probably the only one at this
point. 

I am reading that the real solution is a new bread of CPU that does not
have this vulnerability. It would seem even modifying the existing CPUs
and manufacturing them would take months if not a year or so.  In the
meantime we have to survive with hardware patched with software.   

I read that desktops are the most vulnerable. Maybe that should be any
devise that runs a browser.  The browser is the point of failure. 
Introduce some rogue JavaScript and your memory is compromised.   

This article says [1] one should enable site isolation using Chrome. 

At this point my preventative steps are: 

1) flush all browsers of any usernames, passwords and history. 

2) Only run the latest version of Chrome and only Chrome. 

3) Configure Chrome to run in isolation mode.  

Anyone have any other thoughts? 

Thank you in advance.  

Keith
