Agree with you right up to the last paragraph
Excellent article, except I take exception with your last paragraph.  Making the assertion that the solution lies at the App layer is living in a "fool's paradise".  

"Yes" the App has to have mitigations for its vulnerabilities as they exist at the App level, but that is a far cry from actually securing the operating environment. And without securing the OS operation the App can be made to believe that anything is occurring (or not occurring) as desired to exploit a weakness in the system.

Security is a chain that has to have 'strong links' at every level.

There has been a marketing trend of late, claiming that "their product" can magically secure the operating environment by running it on your App.  Managers love this type of easy solution; it is just a shame that they are largely ineffective, at best just securing some limited aspects of App operation.  At worst they are a lot of 'security theater' and hand waving.

In my opinion, the best approach is a multi-layered solution with a hardware root of trust.  The use of TrustZone is a good first step towards this, and with all the security company acquisitions that ARM is making lately apparently they must be headed in that direction as well.

Now all we have to do is to convince the OS manufacturers that security is important enough to us that they will then start to use some of these hardware security tools that are available to them.

Instead they are releasing "new features" like 'upper / lower case keyboards' and 'long press', as if these are some new revolutionary concepts.  We need them to focus on the real issues, not the fluff.

Maybe voting with our wallets will get their attention.

Improving Enterprise Cybersecurity With XDR
Enterprises are looking at eXtended Detection and Response technologies to improve their abilities to detect, and respond to, threats. While endpoint detection and response is not new to enterprise security, organizations have to improve network visibility, expand data collection and expand threat hunting capabilites if they want their XDR deployments to succeed. This issue of Tech Insights also includes: a market overview for XDR from Omdia, questions to ask before deploying XDR, and an XDR primer.
