We have a lot of standards are available to tackle the hackers or we call pen testers, ethical hackers and all that.

Now, when you said about advanced threats, are you talking about here using a cyber kill chain or APT or MITRE? What exactly when you said about we have to use different techniques? Can you just help me out to understand that?

Absolutely.

So the things you just named, the kill chain, these different techniques, MITRE ATT&CK framework, even the diamond model for attribution, all of those are tools to use and they're very valuable.

But, you know, when this first happened, that was not the case.

Oh, interesting.

And as you said about we have a TTPs, we have a diamond model, we have a cyber kill chain methodologies, we have IO and IOC.

Okay, fine.
