💻 What’s on my mind

Unless you’ve been living under the rock you’ve probably heard about some really serious vulnerabilities Microsoft patched last week in on-premise Exchange servers. Tens of thousands of exchange servers mostly in the US, but otherwise globally, have been compromised.

And now a punch line: Exchange Online service was not vulnerable. As far as it is known Microsoft knew about vulnerabilities since January 5th and I guess they have patched Exchange Online in really short order.

In the light of these last events, it’s getting clearer that on-premise infrastructure is inherently more vulnerable than cloud.

I really think it’s time to fully embrace cloud and leave on-premise solutions to cover specific needs.

Have a nice week.

Sending files in Outlook… attachments or links? Old school email and Outlook users prefer to attach files. But is this still an optimal way to share files with others? Was attaching files ever optimal at all? In my humble opinion using email as a way of sharing and storing files is a serious abuse of the email service itself.
