IEC62443, NIS2 and security testing - a happy marriage? - Secudea bv When the NIS2 EU Directive came into effect, I wondered what the implications would be for security testing in industrial environments. After all, a large part of the NIS2 directive focuses on supply ...

Have a look at my newest post to learn more whether IEC62443, NIS2 and security testing are or can be a happy marriage.

I would not match them, but more like extending the test cases with what is found in the requirements.
But tbh, a good fat/sat approach should already cover all your own security requirements.

True, security requirements should idd be set during design phase and verified. First on paper allowing you to catch low hanging fruit and tailor any testing protocol, second by performing technical tests.

*sigh* this has been a good security practice for several decades already (when I was still installing firewalls), so I find it a bit strange that this suddenly becomes a hot topic... are people forgetting the good stuff, what works, the basics?? Is everybody falling for buzz words instead?

well... I sure hope other tools would also be possible to be used within segmented networks without needing direct access to the internet to fetch updates...

Microsoft ends development of Windows Server Update Services (WSUS) Microsoft has officially announced that Windows Server Update Services (WSUS) is now deprecated, but plans to maintain current functionality and continue publishing updates through the channel.

What are other OT/ICS security folk thinking about WSUS being deprecated?

I'd expected to see more reaction and alternatives being promoted.
