Grant or Block Access

When a user tries to sign in, Azure checks conditions like user group, device, location, and app, then applies rules to allow or block access.

Execution Sample

Azure

If user in 'HR' group AND device is compliant THEN allow access ELSE block access

This policy checks if the user belongs to the HR group and uses a compliant device to decide access.

Process Table

Step	Condition Checked	Condition Result	Action Taken	Access Outcome
1	User group is 'HR'	True	Continue evaluation	Pending
2	Device is compliant	True	Grant access	Access Granted
3	N/A	N/A	End evaluation	Access Granted

💡 All conditions met, access granted to user.

DeviceCompliance	Unknown	Unknown	Compliant	Compliant
Access	Unknown	Pending	Granted	Granted

Key Moments - 2 Insights

Why does access get blocked if the device is not compliant even if the user is in the right group?

Because the policy requires both conditions to be true. As shown in step 2 of the execution_table, if device compliance is false, the action would be to block access.

What happens if the user is not in the specified group?

The evaluation stops early and access is blocked. Step 1 in the execution_table shows that if the user group condition is false, the policy denies access immediately.

Visual Quiz - 3 Questions

Look at the execution_table, what is the Access Outcome after Step 1?

A Pending

B Access Granted

C Access Blocked

D Unknown

💡 Hint

Check the 'Access Outcome' column in row for Step 1 in execution_table.

At which step does the policy decide to grant access?

A Step 3

B Step 1

C Step 2

D Never

💡 Hint

Look at the 'Action Taken' column to find when access is granted.

If the device was not compliant, how would the Access Outcome change at Step 2?

A Access Granted

B Access Blocked

C Pending

D No change

💡 Hint

Refer to the key_moments explanation about device compliance impact.

Concept Snapshot

Conditional Access Policies check user, device, location, and app conditions during sign-in.
If all conditions meet policy rules, access is granted; otherwise, it is blocked.
Policies evaluate step-by-step and stop early if a condition fails.
Common controls include requiring compliant devices or specific user groups.
This helps protect resources by enforcing security rules dynamically.

Full Transcript

Conditional access policies in Azure work by evaluating conditions when a user tries to sign in. The system checks if the user belongs to certain groups, if the device is compliant, the location, and the application being accessed. Based on these checks, it applies controls to either grant or block access. For example, a policy might require the user to be in the HR group and use a compliant device. If both are true, access is granted; if not, access is blocked. The evaluation happens step-by-step and stops as soon as a condition fails. This ensures secure and flexible access management.
