Chasing Chipmunks: One Big Pro Tip for Identity in M365 Disaster Resilience -- Virtualization Review In a recent online tech-ed summit, 'How To Make Microsoft 365 Fail-Proof: Modern Strategies for Resilience,' experts John O'Neill Sr. and Dave Kawula discussed the critical role of identity management...

Thrilled to co-present with Dave Kawula at today's M365 summit! bit.ly/4l4lo3C

Key takeaway: Enable MFA on EVERY admin account (except break glass). No exceptions. The Ubiquiti breach? One compromised admin = millions lost.

Remember: Don't chase the chipmunk - prevent the breach! #InfoSec #MVPBuzz

The Microsoft 365 Security Crisis: 5 Threats That Could Destroy Your Business in 2025 – Azure Innovators

94% of orgs had some sort of breach via M365 last year. Most still think "Microsoft backs up my data" (spoiler-they don't).

M365 attacks are up 300%. One org lost $25.6M to a deepfake call.

Quick wins:
βœ… Test your backup
βœ… Enable admin MFA
βœ… Kill legacy auth

What a blast during my session today! I love talking about reframing cybersecurity through the lens of digital wellness and collective resilience. Nothing better than helping orgs realize that security should enable, rather than prevent, meaningful connections between people and orgs. #CRLVIRTCON

If you use Media Temple for web hosting, dig in ASAP to determine if attackers grabbed your data when Media Temple was breached in November. #BettertoKnow

Field Notice: FN - 70620 - Moving Existing HyperFlex ESXi Hosts to vCenter 7.0 Update 1 Can Unexpectedly Power Off and Delete the HyperFlex Controller VMs - Workaround Provided An interoperability issue between HyperFlex and vCenter 7.0 Update 1 (U1) has been identified that impacts HyperFlex controller virtual machines (VMs) that are managed by vSphere ESX Agent Manager (EAM). At the time of initial publishing of this notice, vCenter and ESXi 7.0 and 7.0 U1 were not supported with HyperFlex, and this notice was issued out of an abundance of caution.HyperFlex Data Platform (HXDP) Software Releases 4.0(2) and 4.5(1) and later now support vCenter Server 7.0 U1c (build 17327517) and later. Refer to the HyperFlex product documentation links in the Background section for full interoperability details.

A VMware bug in vCenter Server 7.0 U1 can power off and delete clusters. Yeah, it definitely stinks.@DaveKawula @SuperCristal1

If you allow RDP, VNC, or any other remote access solution from outside your network PLEASE restrict to only specific IPs. Otherwise, just assume you’re under a brute force attack RIGHT NOW. @DaveKawula @SuperCristal1 #mvpbuzz @betsyweber

Don’t want to force users to sign in with an Apple ID on company devices to install company provided apps? You don’t have to, just manage with @MSIntune. Set your iOS app to Device license instead of User License. @DaveKawula @SuperCristal1 @betsyweber #mvpbuzz

Microsoft Endpoint Manager users, if you allow the Apple Business Manager server token to expire, you must create a new one, revoke the old one, and re-assign your apps in the portal. Renew before it expires to avoid the extra work! #MVPBuzz @DaveKawula @SuperCristal1 @betsyweber
