Je hoeft me niet te geloven als ik je nog eens vertel dat een scan of fotokopie van je identiteitskaart NOOIT nodig is, er zijn immers tientallen andere geldige en betere manieren om je identiteit te bewijzen. Het hoeft maar één k…lnkd.in/e2KCvMwg lnkd.in/eFTjB3mC

Great question from @MsAzureAD What should you do when you need to urgently revoke a user's access? This could be a compromised account, employee termination, insider threat or another reason. The good news is we have a doc that outlines what you should do 👇 In short ❌…

In case of compromised user account, what should we do first and why ? Reset password in AD or revoke entra id session. @merill @JefTek @wiele @DrAzureAD

Good news: vote on chatcontrol postponed. But this monster keeps raising its head: efforts to stop it need to be continued.

Embarrassing how @EU2024BE ends its presidency by pushing #ChatControl, the umpteenth surveillance proposal that promises more safety. Real safety doesn't come with a quick tech fix that can have devastating consequences. Remember: function creep is real!

Owasp data breach. Personal data (from resumes) from 2006-2014 leaked. So important to maintain old ressources or decommission them if possible. Also this one of many examples why retention policies and (automated) clean up processes matter so much. owasp.org/blog/2024/03/2…

Dankzij het detectivewerk van @kennethdee weten we dit nu ook weer: hopelijk belanden je eigen processen-verbaal of gevoelige gerechtsdocumenten niet in een open containertje, klaar voor iedereen om erin te snuisteren. Datalekken, soms - en al te vaak - zijn ze belachelijk.

A #LinkedIn invite from someone who explicitly mentions my blog posts. Guess that counts as an introduction (I don't accept invites without proper introduction, which 95% are recruiters or bots). Great to see people still find their way to my blog, energizes in writing more.
