Hi All,

Greetings for the day!!!

We always talk about SECURITY of our tenant and of course why not, since which is one of the most critical aspect for my organization. I observed / realised that it is always confusing point from where to start implementing SECURITY for my organization. What features should I look into so to make sure things are in place and my tenant is secured

Microsoft suggests following top 10 ways to secure our organization’s business data

SECURITY = Top 10 ways to secure our organizations business data

First and simple step, I will go for MFA – one of the easiest option to secure my organization / company / tenant

Multi Factor Authentication

    • Identity-related attacks like password spray, replay, and phishing are common in today’s environment
    • More than 99.9% of these identity-related attacks are stopped by using multifactor authentication (MFA) and blocking legacy authentication
    • Ensuring that all organizations have at least a basic level of security enabled at no extra cost

Either we can use SECURITY DEFAULTS or CONDITIONAL ACCESS POLICIES to set up MFA. We can not use both the methods together

Available verification methods

  • When we (users) sign in to an application or service and receive an MFA prompt, we can choose from one of registered forms of additional verification.
    • Smart phone – Microsoft Authenticator smart phone app – Microsoft recommends this
    • Fingerprint, face or other biometric attribute
    • Windows Hello for Business
    • FIDO2 security key
    • OATH hardware token
    • SMS
    • Voice Calls

There is very good table provided by Microsoft ( ) – having details like Plan / Recommendation / Type of Customer as

PlanRecommendationType of customer
All Microsoft 365 plansUse security defaults, which require MFA for all user accounts. You can also configure per-user MFA on individual user accounts, but this isn’t recommended.Small business
