CISA Report Only Scratches Surface of Securing Office 365

The CISA report titled “Microsoft Office 365 Security Observations” makes five recommendations to improve security of an Office 365 tenant. The recommendations are valid, but competent administrators won’t take long to implement them. In fact, the worst thing is that consultants brought in to help organizations didn’t seem to have much expertise in securing Office 365.

Unified Labelling Version of Azure Information Protection Client Now Generally Available

Microsoft has released the GA version of the Azure Information Protection client, which reads information about Office 365 sensitivity labels and policies from the Security and Compliance Center. It’s one more step along the path to making it easy for Office 365 tenants to protect their data. Work still has to be done, but at least we can see light at the end of the encryption tunnel.

Microsoft 365 Security and Compliance Centers Now Generally Available

The Microsoft 365 Security and Microsoft 365 Compliance Centers are now generally available. The new consoles will eventually replace the Office 365 Security and Compliance Center (SCC) but some work is needed to fill out their functionality and make the switchover possible. In the meantime, the Office 365 for IT Pros eBook writing team will stay focused on the SCC. And when the time’s right, we’ll switchover.

Eliminating Basic Auth for Exchange Online with AAD Conditional Access Policies

Exchange Online protocol authentication policies control what protocols a user can connect to mailboxes with, but it would be much better if we didn’t have to worry about some old and insecure protocols. Azure Active Directory gives Office 365 tenants the chance to clamp down on IMAP4 and POP3 connections and close off some of the holes that attackers try to exploit. Microsoft says that this can lead to a 67% reduction in account compromises, so that’s a good thing.

Phishing: Your Document Has Been Completed

Phishing attacks through email happen all the time. A new relatively crude one arrived today. It’s easy for the trained eye to detect phishing, but do your Office 365 admins know how to use the tools available in Exchange Online Protection to suppress malware, and do your users know the signs of bad email? In this case, it’s an invitation to click to get to a PDF document to bring you to digitaloceanspaces.com. Some interesting things might happen afterwards, but I really don’t want to find out what occurs when I click the link.
